Clean Air Blog

Last updated: August 2025 This is our third year running this comparison, and it’s become our most-read page. Over that time we’ve seen plenty of models appear and then quietly vanish - often from brands where air purifiers aren’t a core focus. Some disappear entirely, leaving customers with no way to buy replacement filters. That’s why we update this guide each year: to show how purifiers actually perform, which are supported in New Zealand, and how much value they provide. If you’d like to skip ahead, here’s a quick way to jump to the section that matters most to you: Under $300 - Smaller spaces Under $500 - Medium spaces Under $1000 - Larger spaces Over $1000 - Large & commercial spaces Key things to know before comparing purifiers Before we get into the numbers, here are the fundamentals that matter most when choosing a purifier: Clean Air Delivery Rate (CADR):This measures how much clean air a purifier produces (in m³/h). The higher the CADR, the faster and larger a space it can clean. CADR is the single most important metric, far more reliable than “recommended room size” claims, which are often exaggerated. Noise levels (dB):Noise is one of the most practical factors when choosing a purifier. Many brands highlight their lowest “sleep mode” figures, but CADR drops heavily at those speeds. For this guide we’ve used maximum speed noise levels, so comparisons are fair. How to read the numbers: <50 dB - relatively quiet for daytime use, fine in living areas but still very noticeable at night 50–54 dB - modest background noise, upper limit for comfortable indoor environments 55–59 dB - similar to normal conversation, very noticeable if close by 60+ dB - loud and disruptive, best avoided for long periods Price vs performance:The price tag should reflect what the purifier actually delivers. Some big-brand models are expensive but produce less clean air than simpler, better-value units. A quick note on “extra features”When shopping around you’ll see lots of air purifiers with added bells and whistles. Some of these aren’t just unnecessary, they can be unhelpful or even harmful: Ionisers / Negative ion generators - can create ozone and just push particles onto surfaces instead of removing them. These are used to improve CADR figures, without filtering out particulates. UV lights - sound impressive, but don’t get enough contact time to work in fast-moving air. HEPA filters already capture these particles. Auto sensors - often cheap, inaccurate and misleading. We recommend a separate, accurate monitor if you want to track your indoor air properly. 👉 For a full breakdown, see our article: What features matter when choosing an air purifier. How we source and present the data We’ve made every effort to ensure the numbers here are accurate and up to date, but air purifier data can be patchy. Some brands don’t publish CADR or noise levels at all (we’re looking at you Dyson and Shark), or publish only partial figures. Here’s the approach we use, for all purifiers we find available in New Zealand: Manufacturer or retailer specs - when CADR and noise levels are published clearly. EnergyStar database - where CADR is independently verified. Independent tester reviews (e.g. Housefresh, Rtings) when official data isn’t available. If no reliable CADR data can be found, we exclude the model. That’s why this guide shows every purifier in NZ with verifiable performance data. While we’ve double-checked everything, there may still be small differences between sources. Why trust this guide? The internet is full of “Top 10 Air Purifiers” and “Best Purifiers for Dust” lists - even from well-known outlets. Unfortunately, many are built to generate commission, not to give you the best advice. We want to be upfront: yes, we are selling some of the purifiers in this guide. But unlike affiliate-driven lists, our business depends on you being satisfied years down the track. That means filters being available, performance matching the claims, and you getting genuine value. Why you can’t trust every “Best Of” list To show what we mean: in 2024, the NZ Herald published their “Best Air Purifiers in New Zealand” picks. The problems? Many. It was clear this was written by someone (or AI) with no knowledge of air purifiers. They included models with poor clean air performance, no filters available and unsupported models drop shipped from overseas. Their reason for publishing isn’t to inform you, it’s to earn commission on the products they list. We broke this down in detail here: It's a good reminder that while these lists look authoritative, they don't hold up when you check the numbers. Our aim is different: to compare all models where data exists, show how they stack up, and make it transparent why certain units come out ahead. Comparison Analysis (2025): Now that we’ve outlined the key considerations, let’s step into the results. This updated analysis, conducted in August 2025, covers Smart Air purifiers alongside other well-known brands like Breville, Dyson, Shark, Sunbeam, TruSens, Winix, Xiaomi and more. These are all available from New Zealand retailers including the likes of Briscoes, PB Tech, and Noel Leeming. We researched a total of 65 models, but we could only find reliable CADR and noise data on 59 of these. The others were excluded due to missing or unreliable specifications - as explained earlier, if we can’t source credible data, we don’t include the unit at all. Before diving into the detailed breakdowns, it’s worth noting a pattern you’ll soon see across the charts: price doesn’t always mean better performance. In fact, some of the highest-priced purifiers deliver relatively low CADR, while some of the most affordable units outperform their category. Budget Air Purifiers Under $300 (for smaller spaces, up to ~40m²) This category is aimed at bedrooms, nurseries, and smaller apartments. In 2025, we assessed 12 models in this bracket, from brands such as Fellowes, Breathing Better, Sheffield, Sunbeam, Breville, TruSens, and more. Among these, The Smart Air Sqair is the stand out winner. Its CADR of 315 m³/h is more than 50% higher than the next best competitor in this group. To put that in context, the Sqair is suited for spaces up to around 43m², while the next best options in this price range are only suitable for around 26m² (despite often advertising larger “room sizes”). Noise is another advantage. At 52 dB max, the Sqair runs 7–12 dB quieter than its closest rivals, making it more practical for everyday use. And with no ionisers or gimmicks, it remains a safe choice for households with respiratory concerns or young children. Graph 1: Air purifiers under $300 in NZ (price vs max noise vs CADR). Table 1: Budget Air Purifier Highlights   Brand Model Max CADR  Max Noise Price Smart Air The Sqair 315m³/hr 52dB $299.99 Sunbeam Fresh Protect 193m³/hr 59dB $248.00 Trusens Z2000 190m³/hr 64dB $229.00 Breville The Easy Connect 91m³/hr 60dB $270.00 A striking contrast. While the Sqair comfortably outperforms, the Breville Easy Connect struggles. Despite its $270 price tag, it’s loud (60dB) and only suited for spaces of ~12m². It’s a clear example of how price doesn’t always equal performance Air Purifiers $300 to $500 in New Zealand (for medium spaces, up to ~60m²) In this range we start to see purifiers suited to medium living rooms, apartments, and shared spaces. For 2025 we assessed 14 models in this bracket, from brands including Daikin, Shark, Winix, Breville, Breathing Better, Xiaomi, TruSens and more. This segment brings more competition - but one model stands out. The Smart Air SA600 delivers a CADR of 500 m³/h, making it suitable for spaces of ~60m². It shares the top cleaning power with Xiaomi’s Pro 4, but does so at just 53 dB on maximum. By comparison, the Xiaomi Pro 4 and Xiaomi 4 hit 64 dB and 63 dB respectively, which makes them noticeably louder if run at full capacity. Graph 2: Air Purifiers $300- $500 in NZ (Price vs max noise vs CADR). Table 2: Medium Air Purifier Under $500 Highlights   Brand Model Max CADR  Max Noise Price Smart Air SA600 500m³/hr 53dB $439.99 Xiaomi Pro 4 Smart Air 500m³/hr 64dB $400.00 Xiaomi 4 Smart Air 400m³/hr 63dB $325.00 Shark NeverChage 5 165m³/hr 55dB* $350.00 * Noise level reported between 55–65 dB depending on the source. The Shark NeverChange 5 is widely available in NZ retailers and heavily marketed - but its performance is underwhelming. With a CADR of only ~165 m³/h, it’s below the Sqair running on medium (180 m³/h) and only slightly above the SA600 on low speed (135 m³/h) - except the SA600 achieves that at just 24 dB, compared to the Shark’s 55+ dB. This highlights why sourcing transparent CADR figures matters, and why marketing alone can be misleading. Air Purifiers for larger spaces under $1000 in New Zealand (Up to ~85m²) Now we’re moving into units suited for larger living areas, classrooms, clinics, and open-plan apartments. Prices rise sharply in this category, but as we’ve already seen, cost doesn’t always equal performance. In 2025 we assessed 15 models from brands including Sharp, Daikin, Oransi, Winix, Mitsubishi, Breville, and Dyson. Performance varies widely - some units offer genuine large-space cleaning, while others fall far short despite premium pricing. The standout remains the Smart Air Blast Mini Mk II. With a CADR of 740 m³/h, it’s comfortably the most powerful purifier in this price band. Even more impressive: it achieves this at just 49 dB, making it one of the quietest in the group. This combination of high CADR and low noise sets it apart from the competition. The Oransi Mod HEPA is also worth noting. At 574 m³/h and 49 dB, it doesn’t quite reach the Blast Mini’s output but is still a strong performer for medium–large rooms. Like Smart Air, Oransi avoids ionisers and auto sensors, focusing on straightforward HEPA filtration. By contrast, Dyson’s premium models again show very low performance for the price. The TP07 manages just 153 m³/h, and the HP03 only 113 m³/h, both at a noisy 62 dB. With Dyson not publishing CADR, these figures are drawn from independent testing, where results have consistently been underwhelming. Graph 3: Air purifiers $500 - $999 in New Zealand (price vs max noise vs CADR). Table 3: Large Space Air Purifier Highlights Brand Model Max CADR  Max Noise Price Smart Air Blast Mini Mk II 740m³/hr 49dB $799.99 Oransi Mod Hepa 574m³/hr 49dB $850.00 Mitsubishi ElitePure 508m³/hr 55dB $520.00 Dyson Pure Hot+Cool HP03 113m³/hr 62dB $899.00 The Blast Mini dominates on CADR and noise, providing exceptional value. On the other end, Dyson’s numbers highlight how marketing can mask poor real-world performance. Large & Commercial Air Purifiers over $1000 in New Zealand (Up to ~130m²) This category targets large homes, gyms, clinical settings, and classrooms - places where serious air cleaning power matters. We evaluated 15 models in this price range from brands including IQAir, Trusens, Dyson, Breathing Better, and more. (Note: we excluded ultra-premium units above $10,000 from the graph to keep things readable.) As in previous brackets, cost doesn’t always align with performance - and noise. Many premium models may look impressive but don’t add up in real-world use. The Smart Air Blast Mk II remains the standout. At 950 m³/h CADR and a quiet 43 dB, it's the most powerful and one of the quietest options across all price categories. It outperforms or matches other high-end units while running significantly quieter. The Trusens Z7000 comes closest in raw CADR at 930 m³/h, but does so at a loud 66 dB, a big trade-off in daily use. The Trusens Z6000 is slightly less powerful (880 m³/h) but still noisy at 63 dB. At the ultra-premium end, IQAir models stand out for their build quality and serious filter packs, including substantial carbon beds in some variants. Units like the HealthPro 250 or GC MultiGas don’t compete on CADR per dollar, but they are trusted for specialist applications where filtration quality (including gases and chemicals) matters. By contrast: Breathing Better X-Large Room: 800 m³/h at 70 dB - very loud for the output. Fellowes AeraMax Pro AM4: 748 m³/h at 68 dB, but costing over $2,000. Dyson’s premium Hot + Cool range: CADR only 239–311 m³/h with noise around 62 dB - performance more akin to the Sqair, despite being sold as a premium purifier. Their appeal lies in sleek design and fan/heating features, but in pure cleaning efficiency they lag behind. Graph 4: Air Purifiers $1000+ in New Zealand (price vs max noise vs CADR). Table 4: Large & Commercial Space Air Purifier Over $1000 Highlights Brand Model Max CADR  Max Noise Price Smart Air Blast Mk II 950m³/hr 43dB $1100 Trusens Z7000 930m³/hr 66dB $1830 Trusens Z6000 880m³/hr 63dB $1700 IQAir CleanZone SL 820m³/hr 56dB $11,500 Breathing Better X-Large Room Purifier 800m³/hr 70dB $1499 I-Air Pro Air Healer 600m³/hr 61dB $12,883 Dyson Purifier Hot + Cool 311m³/hr 62dB $1099 Takeaway: In this price bracket, the trend is clear! Most high-CADR units are very loud. The Blast breaks that pattern, combining the best output with surprising quietness. Trusens offers similar airflow but at far higher noise, while IQAir justifies its pricing more through specialist filters and build quality than through raw CADR. Dyson, once again, illustrates how sleek design and multi-function marketing can mask very modest air cleaning performance. Wrapping Up: Our 2025 analysis makes one thing clear: price alone is not a reliable guide to purifier performance. Time and again we’ve seen models marketed as premium struggle to match the cleaning power of more straightforward units, and in many cases they’re also far noisier. Across every price bracket, the purifiers we stock have consistently come out among the top performers, not just on CADR but also on noise. When choosing a purifier, focus on the fundamentals: CADR, noise, HEPA filtration and of course price. If those aren’t right, no amount of flashy features or brand reputation will make up the difference. 👉 Still not sure which model fits your space?

We’ve expanded our air quality monitor range to include Temtop. Like our existing models from Qingping, Temtop has a reputation for well-priced products with high levels of accuracy. Accuracy is non-negotiable for us, so we started with models that already have independent test results and used those as anchors in a simple, real-world comparison. We then co-located all six monitors (Qingping and Temtop) and aligned the data over several days. The curves moved together, and the typical gaps were small. That gives us confidence that the new additions sit in line with our verified units. Independent Testing Anchors Southcoast AQMD, based in California has a program where they compare air quality monitors with high grade reference equipment. This provides independent test data for dozens of models, from low cost ones like the QP Lite to ones costing thousands of dollars. For PM2.5, all the results are published here. Several of our units already have results available from Southcoast AQMD. All showed strong correlations with the reference equipment for PM2.5 measurements, and low mean errors - often beating monitors costing thousands of dollars!  Model Field R2 (Correlation) Field MAE (Absolute Error) Qingping Lite 0.85 to 0.93 1.8 to 3.6 Qingping Pro 0.86 to 0.90 1.8 to 2.3 Temtop LKC-1000S+ 0.91 to 0.92 3.1 to 3.6 Note, original model of Pro and Temtop LKC were tested, updated models used for our comparison testing. Why PM2.5 Matters PM2.5 are tiny particles that can reach deep into the lungs and even the bloodstream. When air pollution is talked about, it typically refers to levels of PM2.5, due to the serious health impacts. In New Zealand, indoor levels can often be higher than outdoors. Seeing the levels and changes in your home or workplace can help you decide if interventions such as ventilation or air purification is required.  What we tested   Models: Qingping Lite, Qingping Pro 2, Temtop M10i, Temtop M10+, Temtop S1+ and Temtop LKC-1000S+ 2nd. Environment: Same bench in an apartment (Christchurch), co-located and away from air vents. Period: 14 - 18 August 2025, hourly measurement results Objective: Check how closely the models track together in real conditions, using indepdently tested units as the benchmark Method and limitations Recording frequency: We aligned measurements to the unit with the lowest recording frequency (M10+), so all results are reported hourly.  Time adjustments: Not all units were recording exactly on the hour, so the closest recording to the hour was used. In some cases this was 5mins before or after the hour. Units plugged in: All units were plugged in to ensure regular readings and updating PM2.5 Exposure: Two spikes occured due to cooking with the frypan. No air cleaning was used, in order to keep levels high for longer. Results By the numbers Most pairs have correlations between 0.95 and 0.99, indicating very high levels of correlation Typical difference: Around ~1 µg/m³ when averaged over the period Mean reading: Small spread across devices, mean PM2.5 reading for the each device across the entire period was between 3.2 and 5.0 µg/m³. Variances observed during initial PM2.5 spikes, due to timing of readings. What this means for buyers We can confidently say the PM2.5 readings on our units are all accurate and reliable! Models we have which haven't got independent Southcoast AQMD reports very closely track those that do. This is as good as it gets for air quality monitors! If you're looking for affordable and accurate air quality monitors, look no further than our range of PM2.5 capable monitors! A note about PM10 One of the reasons we focus on PM2.5 is that PM10 numbers from low-cost optical sensors are generally less reliable than PM2.5. This is shown in the Southcoast AQMD results, where PM10 accuracies were always quite a bit lower than for PM2.5. This essentially boils down it it being more complex to measure for PM10 sized particles. If you'd like to learn more, there's a great writeup about this here.

It's hard to beat the aroma of garlic or steak sizzling away on the frypan as it fills your kitchen with flavour. But under those delicious scents lies fine particles called PM2.5, that can travel deep into your lungs and affect your indoor air quality. In a test in a Christchurch apartment in May 2025, cooking on a front burner pushed PM2.5 levels throughout the apartment into the hazardous range, even with the rangehood set to full power. In this article we'll show you exactly how we measured those spikes, how bad it got and how much of a difference using Air Purifiers made. Armed with this information, you can ensure you keep your air clean, whatever you're cooking! Figure 1: Rough Layout of Apartment + Positions of Monitors and Purifiers First Test: Baseline (No Air Cleaning) This experiment actually started accidentally, after noticing the air quality as measured on my QP Pro units was at very concerning levels. It turned out that even at full power, my rangehood barely captured smoke from the front two hobs. This is definitely a bit of a surprise given this is a relatively new apartment.After frying for about 15 minutes, it seemed a little hazy and smokey inside. I checked my air quality monitors in both the lounge and separate bedroom, and both showed very high readings! With PM2.5 counts of over 300 µg/m³, you really want to limit your exposure to this. For perspective, this is about three times higher than the average pollution level in Delhi, and is well into 'hazardous' air quality levels.  If you stop cooking, you immediately remove the PM2.5 source. But on a chilly day with windows closed, those particles can linger for hours. While the rangehood extractor fan was used, it hadn't effectively drawn out the cooking smoke. Being a chilly day, no windows or doors were opened. Here is how the air quality looked over the evening: Figure 2: PM2.5 Readings in Bedroom and Lounge from Cooking Note: PM2.5 to air quality ratings sourced from EPA AQI breakpoints. As you can see, the PM2.5 levels shot up very quickly when the cooking started. For several hours the air quality was at or above unhealthy levels, even lingering at hazardous amounts for awhile! What does this mean? Basically the equivalent of smoking about 1.3 cigarettes! Definitely not something you want to be regularly exposed to. Especially if you have asthma or other breathing sensitivities. Second Test: With Air Purifiers This time, our accidental experiment was repeated with one key tweak, switching on air purifiers when the concentrations peaked. The apartment is well covered on that front, with a Smart Air Sqair in the bedroom and a Smart Air SA600 in the main living/kitchen area.You'll notice from the layout graphic earlier, we've also placed the purifiers away from the air quality monitors. This helps ensure the readings are representative of the actual air quality in the apartment, and not just the air quality around the purifier.Now the big reveal, how much of a difference can the air purifiers make? We allowed the PM2.5 concentrations to reach similar levels to our baseline test, and then turned both purifiers on at their max power settings. Figure 3: PM2.5 Readings in Bedroom and Lounge from Cooking, using Air Purifiers The outcome? In just 30mins, PM2.5 concentrations had dropped by over 90% - this is compared to between 25% and 29% when we didn't use them. Air quality reached the optimal 'Good' level within 45mins in the bedroom and within 1 hour in the main living area!Why are these air purifiers so effective at removing cooking pollutants and smoke? It's all thanks to the combination of HEPA filters and high Clean Air Delivery Rate (CADR).  The HEPA filters on both units are very effective at absorbing harmful particulate matter in the air, such as from frying and smoke. However, a good HEPA filter won't do much if the purifier isn't able to send much air through it. With CADRs of 315m³/hr and 500m³/hr respectively, the Sqair and SA600 are able to push significant amounts of polluted air through their filters. This makes them best in class when it comes to how effectively they purify air. As you can see, we can back this claim up with real data! Smart Air Sqair Smart Air SA600 Stylish, powerful and quiet at a great price. Perfect for the bedroom, or any space up to 43m². Dual inlets with filters on each side. Serious cleaning power for larger spaces up to 60m², while remaining quiet. Other air quality measures you can take: Ensuring your rangehood is working effectively will certainly help reduce the amount of PM2.5 in the air. Mechanical ventilation i.e. HRV/DVS etc if you have it. This will bring in air from outside or the roof space which should be much less polluted. Finally opening windows and doors to let a breeze through, even if for just a short while will also quickly help lower the amount of pollutants. A note around Gas stoves: This experiment was done with an electric hob. Gas stoves are known to release more PM2.5 as well as Nitrogen Dioxide as they combust - the same concerning compound released by car exhaust fumes (diesel particularly). It's even more important to ensure effective ventilation if you're cooking with gas! Wrapping Up These tests show cooking can spike PM2.5 into hazardous levels, and that a quality HEPA purifier (like our Sqair or SA600) cuts those peaks by over 90% in under 30 minutes. Combine purifiers with a properly positioned rangehood and some fresh-air ventilation, and you’ll keep your home’s air in the “Good” zone, even at dinner time. Want to test this yourself? Grab yourself one of our selection of affordable air quality monitors which can measure PM2.5, such as the QP Pro 2, and gain insights like this into your air quality!

Like many Kiwis, I used to never give a second thought to the air I'm breathing. Our landscape isn't covered in polluting factories or coal plants and we're known for our (relative) clean air. However, after learning more about indoor air quality, I decided to start monitoring the air inside and was surprised by what I discovered! How do you Monitor the Air? While it's not an uncommon thing to do overseas, monitoring air quality is still something not many Kiwis are familiar with. While it's possible to pay professionals to come in and do a detailed report, there is a much easier (and cheaper) way. Enter the Indoor Air Quality Monitor, a device with sensors to measure air quality issues such as PM2.5, CO2, VOCs and more. For the past 2 years I've used a QP Lite, QP Pro and Smart Air CO2 Monitor to keep tabs on the air in my home. With an affordable price, high accuracy and data download ability, they're some of the best options on the market and we're pleased to stock them here at Snap Air. First Surprise: CO2 Levels While Sleeping Like many of us, I took it for granted that sometimes we'll wake up feeling groggy, tired and maybe with a bit of a headache. While there are many possible causes for this, have you ever considered CO2 might be behind it? Bedrooms are small spaces and if you close the door and windows, where does fresh air come from? As we breathe oxygen is converted to CO2 and without ventilation the levels can rise surprisingly fast! Especially if you have a partner in the same bedroom. CO2 levels are reported in parts per million, with outdoor air being around 420ppm. Once the air reaches 1000-2000ppm you'll typically experience drowsiness and from 2000-5000ppm headaches and other complaints can occur. I was very surprised to see the levels for my bedroom at night regularly reach over 3000ppm! Once I improved the ventilation, I noticed I'd wake up feeling less groggy and more alert.  Below is an example comparing relatively good ventilation in a bedroom (initially) then poor ventilation later in the week. You can also see just how quickly the CO2 levels drop when ventilation is introduced (opening the door) in the morning! CO2 Concentration Levels: Measured with Smart Air CO2 Monitor Second Surprise: VOC Levels in a New Apartment Having moved into a newly built apartment for a period of time in 2023, I found the 'new building smell' very powerful and I would often get headaches. Unfortunately this is a common experience for many new home owners, as the off gassing from paint, flooring and fabrics etc. produces VOCs like Formaldehyde and Benzene. These can cause symptoms like headaches, respiratory issues, dizziness and throat irritations. There was a sharp increase in average VOC levels reported on my QP Pro after moving into the apartment, compared to an older existing house.  Previously, measurements were around 0.3-0.4 mg of TVOC per m³. In the new building, it was 10 times higher and would be between 3 and 4mg per m³. This puts it in the potentially dangerous threshold. Luckily there is action that can be taken to help reduce these levels. The most effective measure is introducing fresh air by opening doors and/or windows. You can also achieve this with mechanical ventilation. If neither of these options are possible, consider an Air Purifier with Activated Carbon Filter. Here are some readings from the apartment showing the slow rise of VOC levels, then how quickly they get eliminated by opening windows and allowing a breeze through! TVOC Concentrations: Measured by QP Pro Air Quality Monitor Third Surprise: PM2.5 Levels from Vaping While there has been a surge in vaping in recent years, we're still learning about its potential impacts. Having lived with someone who vapes in their room, I've been able to see how it impacts on air quality - especially when ventilation is limited. While it produces a fine mist and sends chemicals into the air, the process of vaporising the liquid also sends particulate matter into the air, including harmful PM2.5. To learn more about PM2.5, see the below video: While I wasn't surprised to see vaping having an impact on air quality, I was surprised at just how high the PM2.5 levels would get - even while in a different room. We've had reports from some of our customers about being impacted by others in their household vaping, which isn't surprising given these results! On the plus side, levels do drop fairly quickly back to normal once the vaping stops. However, peak concentrations ended up at levels you'd see in the most polluted cities in the world, at their absolute worst! The below graph shows the levels of PM2.5 measured from an adjacent room to the one being vaped in. PM2.5 Levels: Measured with QP Pro Air Quality Monitor: Wrapping Up Ready to make your own discoveries in air quality? We've got you covered with accurate and affordable air quality monitors! Feel free to leave a comment below if you found anything interesting when you started monitoring your air!

Whether it's moving into a new home or doing some DIY renovations, many of us will be familiar with that 'new home smell'. Unfortunately, behind that smell are a number of potentially dangerous chemicals or VOCs such as formaldehyde! For some this may cause headaches, dizziness and other health issues. This brings us to the question: How do you keep yourself safe from these VOCs and can an air purifier help? The good news is there are ways to mitigate these VOCs and the right air purifier can definitely help! Understanding VOCs and Their Sources VOCs are emitted as gases from certain solids or liquids. Common sources in new builds and renovations include: Formaldehyde: Found in building materials like plywood, particleboard, and adhesives. Benzene: Emitted from paints, glues, and cleaning products. Toluene: Present in paints, paint thinners, and adhesives. Health Impacts Exposure to VOCs can cause, amongst other things: Headaches Dizziness Respiratory issues Eye, nose, and throat irritation Monitoring VOC levels with an Air Quality Monitor Using an air quality monitor with a TVOC sensor, like our QP Pro 2 or the Temtop M10 can help you gauge VOC levels in your home. While you won't see levels of each specific chemicals, measuring the VOCs will help give a picture of baseline levels of VOCs in the air and can show the effectiveness of different tactics in reducing VOCs. Effective Strategies for Reducing VOCs Ventilation The most effective way to reduce VOCs is through ventilation: Mechanical Ventilation: Use exhaust fans or air exchangers like HRV systems. Natural Ventilation: Open windows and doors to create a strong cross breeze. Formaldehyde Cookouts These are a way to force more formaldehyde from building materials, furniture etc. in a shorter period of time. Note you should avoid being inside when the cookout is run. Smart Air have written a detailed guide here, however the basic process is: 1. Close windows/doors and increase temperature, through heating or naturally with sunlight. Aim for 30+ degrees if possible. 2. Keep the temperature up for a few hours, ideally 6-8 if possible. 3. When you return, open windows and doors to remove the formaldehyde from the air and return the space to a normal temperature. 4. Repeat this several times  Air Purifiers with Activated Carbon Filters An air purifier with a carbon (VOC) filter can provide additional assistance, especially when ventilation isn't possible. Key Factors to Consider: Amount of Carbon: This determines the amount of VOCs which can be filtered before the filter becomes saturated. Some mesh-style "carbon filters" may last only a few minutes in high VOC environments. Separate Carbon Filter: Allows for easy replacement when needed, as in high VOC situations the Carbon Filter will likely need replacing well before the HEPA filter. Our Recommended Purifiers: Sqair: 120g of activated carbon per filter. SA600: 140g per filter (2 per purifier). Blast Mini: 650g of activated carbon per filter (optional extra). Blast: 1.06kg of activated carbon per filter (optional extra). For additional VOC cleaning power, you can remove the HEPA filter and use multiple carbon filters in our purifiers.   Wrapping Up VOCs are an unfortunate reality in newly built or renovated homes. It's essential to tackle these to maintain good indoor air quality and health. Ventilation, both mechanical and natural, is the most effective strategy. Additionally, using air purifiers with plenty of activated carbon can provide assistance, especially when ventilation is not possible. Formaldehyde Cookouts are an additional tool to help lower the levels of formaldehyde being released.

In New Zealand, many homes struggle with dampness, especially over the colder winter months. This makes dehumidifiers a common household appliance. As awareness about indoor air quality increases, you might naturally consider an air purifier and dehumidifier combo unit. They promise the benefits of both devices in one, but are they truly effective? This blog explores whether these combo units are worthwhile, especially compared to standalone devices. How Air Purifiers and Dehumidifiers Work Air Purifiers Air purifiers are designed to remove pollutants from the air, including dust, pollen, pet dander, mould spores, and other allergens. They work by drawing air through filters, such as HEPA filters, which trap these particles before releasing the cleaned air back into the room. Dehumidifiers Dehumidifiers, on the other hand, are built to reduce moisture levels in the air. They work by drawing in humid air, cooling it to condense the moisture, and then expelling the drier air. This process helps prevent mould growth and reduces dampness in homes. The Promise of Combo Units The idea behind combo units is appealing: one device that handles both air purification and humidity control. Since both appliances deal with air, combining them seems logical. Why get two separate appliances when they can be combined into one? Different Machinery Requirements However, as you can see from the above images, air purifiers and dehumidifiers require very different internal mechanisms to perform their functions. Combining them into a single unit results in a compromise, where neither function is performed as effectively as in standalone units. Performance in Small Spaces In small spaces like bedrooms or laundries, a combo unit might be passable. However, in larger spaces, the limitations become more apparent. Evaluating Combo Units in NZ We did some research on the available combo models in New Zealand. Note we haven't physically tested these, but rely on the figures provided by the manufacturers. The primary metrics we looked at were CADR (Clean Air Delivery Rate) to assess the air purification ability and the daily moisture removal amounts. As a benchmark for the CADR, 200m³/hour makes it suitable for a space of about 27m². Our base model air purifier, the Sqair has a CADR of 315m³/hour and is available for a price of $299.99. Generally moisture removal levels for standalone dehumidifiers start at about 10L/day for low price models and top out at about 40-50L/day for higher end models. High-End Models Philips Series 5000: Priced around $1200, it offers moisture removal of 25L/day and a CADR of 270m³/hour which is close to our Sqair, but comes at a big price tag to achieve this. Breville Smart Dry 2 in 1: Priced at round $600, it removes 21L/day of moisture and has a CADR of 195m³/hour. This is comparable to the Sqair running on medium speed. Budget Models Unfortunately we're extremely limited in our ability to compare other models we've seen by Sheffield, Dimplex & My Genie. None of these provide any information about CADR, but given their small sizes and low dehumidification performance we can't imagine the CADR is suitable for anything except the very smallest of spaces. However a model shared by Sheffield & My Genie was only able to dehumidify 750mL per day, much much lower than any comparable unit! The Case for Standalone Units Given the high cost of a half-decent combo unit, let's look at why standalone units are the best option for most situations. Efficiency and Performance Standalone air purifiers and dehumidifiers are designed specifically for their respective functions, ensuring optimal performance. A dedicated air purifier will have a higher CADR, and a standalone dehumidifier will remove moisture more effectively. Flexibility Using separate units allows you to address specific needs as they arise. For instance, you can run just the air purifier during pollen season or just the dehumidifier during humid months, saving energy and wear on the devices. You also have significantly more options for features, performance ability etc. Another point is a combo unit means there is one point of failure. For example we've seen reviewers unable to find replacement filters, meaning they can't use the air purifier and they're left with an under-performing dehumidifier. Final Thoughts While air purifier and dehumidifier combo units might seem convenient, they often fall short in performance compared to using separate, dedicated units. If you have space for only one device and are willing to spend a considerable amount, a high-end combo unit might suffice for a small area. However, for most situations, investing in separate air purifier and dehumidifier units will provide better air quality and moisture control.

Why should you consider CO2 monitoring? Whether its the home, office, school, clinic or bar, monitoring CO2 levels is an important consideration to keep people healthy! Awareness about indoor air quality has been growing, especially since covid has brought in many lessons about virus transmission indoors. The importance of ventilation and filtering has been made clear but it's important to have the right data to know how effective this is and when to take action. Why CO2 Monitoring Matters The Importance of CO2 Monitoring to Avoid Illness Monitoring CO2 levels is important because high concentrations indicate that you're breathing in recycled air from others, increasing the chances of transmitting viruses and other pathogens. When CO2 levels are high, it's important to take action by opening windows or increasing ventilation to ensure fresh air circulation. When this isn't an option, using an air purifier will help by capturing viruses and pathogens in the HEPA filter. The Impacts of CO2 on your health High concentrations of CO2 can also have direct impacts on your health. That afternoon lull in the office? Might be because of high CO2 levels! It can cause feelings of drowsiness, headaches and difficulties concentrating.

As New Zealanders, we're used to relatively clean air and beautiful nature. However, with the recent Port Hills fire near Christchurch in February 2024, we're reminded of the fact it isn't always the case. While we were fortunate that the smoke largely stayed away from the city, we aren't always that lucky. Smoke from fires, whether from local sources or even as far away as Australia, can travel large distances and impact our air quality. And it's not just wildfires; in cooler times, farm burn-offs and wood burners can also affect the air we breathe. Can Air Purifiers Help with Smoke? Absolutely! Air purifiers equipped with HEPA filters can capture virtually all smoke particles, including the harmful PM2.5 and smaller sized ones. These particles are so small they can penetrate deep into our lungs, causing a range of health issues. The only thing to note is that the purifier needs to be sized correctly (see more below). A carbon filter can also help remove the odour of smoke and any potentially dangerous volatile organic compounds (VOCs). Key Points Summary Wildfire smoke and pollution from wood burners can significantly impact air quality in New Zealand. Even brief exposure to smoke can be harmful, especially due to PM2.5 particles. Staying indoors, closing windows and doors, and turning off external air ventilation systems can help reduce exposure. Air purifiers with HEPA and carbon filters are effective at cleaning indoor air from smoke particles and odours. The Health Impacts of Smoke Understanding PM2.5 Particles Smoke is rich in PM2.5 particles, which are tiny enough to bypass our body's natural defenses and penetrate deep into the lungs and bloodstream. This can lead to respiratory issues, aggravated asthma, and even cardiovascular problems. The importance of reducing exposure to these particles cannot be overstated, especially during smoke events. Reducing Smoke in Your Home Seal Your Home The first line of defense is to keep smoke out. This means staying indoors as much as possible during smoky conditions, closing windows and doors, and turning off ventilation systems that draw in outside air. However, since homes are not completely airtight, some smoke will inevitably get in. Clean the Air This is where air purifiers come into play. A good air purifier, appropriately sized for the room, can significantly reduce indoor smoke levels. The HEPA filter captures fine particles, while a carbon filter tackles smoke odours and VOCs. Choosing the Right Air Purifier When selecting an air purifier, consider the size of the area you need to purify and ensure the purifier is rated for that size. Look for models with true HEPA filters and activated carbon filters for the best protection against smoke. Also look to avoid ones which disperse negative ions or contain ionisers, as these may worsen respiratory symptoms. For more information check out our detailed guide on choosing an air purifier. Wrapping up Despite our generally clean air, our natural environment comes with its challenges, including the risk of smoke from wildfires and other sources. By understanding the risks and taking proactive steps to protect indoor air quality, we can safeguard our health against the harmful effects of smoke. Remember, the right air purifier can make all the difference in keeping your home's air clean and safe. Our online store contains a selection of effective and affordable air purifiers and air quality monitors designed to keep you safe from smoke. Stay safe, breathe easy, and protect your health by being prepared for smoky conditions.

Do air purifiers work for mould allergies? Absolutely, air purifiers with HEPA filters can be a game-changer for those with mould allergies. They're great at capturing airborne spores that can trigger allergic reactions. However, it's important to understand that while air purifiers can help manage the allergens in the air, they don't eliminate the source of mould growth. For that, you need to tackle the dampness and humidity that mould thrives on – and a dehumidifier can be instrumental in this battle. Key Points Summary Air purifiers can help with airborne mould spores, reducing allergens in the environment. They cannot remove existing mould growth, which requires physical cleaning and humidity control. Dehumidifiers are essential in preventing mould by maintaining low humidity. Combined air purifier and dehumidifier units exist but may not be as effective as separate appliances. HEPA filters in air purifiers are effective against mould spores, benefiting those with allergies and asthma. Our range features powerful, affordable air purifiers with HEPA filters, perfect for New Zealand homes. Understanding Mould Allergies and Air Purifiers The Battle Against Airborne Spores Air purifiers are designed to filter out the tiny, airborne adversaries that mould spores can be for many of us. A HEPA filter is particularly effective, capturing particles smaller than 0.01 microns. Much smaller than the typical 3 to 40 micron sizes of mould! When Air Purifiers Meet Mould While air purifiers are perfect for cleaning the air, they can't fight mould growth on surfaces. Regular cleaning and controlling room humidity are essential steps in preventing mould from taking hold in your home. Combating Humidity with Dehumidifiers Dehumidifiers play a pivotal role in mould prevention by maintaining an environment that's inhospitable for mould growth. Keeping indoor humidity below 50% can significantly reduce the risk of mould and keep you comfortable. All-in-One: Solution or Compromise? The market offers devices that combine an air purifier and a dehumidifier. While they save space, they often lack the power needed for larger areas, making them suitable only for very small rooms. When it comes to the Air Purifiers on these units, they fall well short of being effective for anything beyond a medium sized bedroom. Because of this, we recommend purchasing standalone units of each. If you're interested in learning more, we've written an article on these combo units. Health Impacts of Mould Mould is not just an aesthetic issue or a homeowner's nuisance; it's a health hazard, particularly for those with allergies or respiratory conditions. Understanding the full scope of its impact can help prioritise why air quality management is essential. The Allergic Reactions to Mould Exposure to mould can trigger a variety of symptoms in sensitive individuals. These may include sneezing, runny or blocked nose, red eyes, and skin rash. For those with mould allergies, these symptoms can be more severe, leading to persistent allergic reactions that can significantly affect quality of life. Mould's Effect on Asthma and Other Respiratory Issues For asthmatics, mould can be particularly harmful. It has the potential to increase the frequency and severity of asthma attacks. Even those without pre-existing conditions may experience respiratory issues in mould-infested environments, such as coughing, wheezing, or shortness of breath. Chronic exposure can even lead to the development of respiratory illnesses in otherwise healthy individuals. Our Powerful, Affordable Solutions Meet Our HEPA Heroes Our air purifiers are equipped with HEPA filters and are designed to be powerful enough for New Zealand's varied home sizes, yet affordable to fit within your budget. With our units, you can ensure that the air in your home stays clean and clear of mould allergens. Wrapping Up Air purifiers are a formidable defence against mould allergies, but remember, they're part of a larger strategy that includes moisture control and regular cleaning. With the right combination of air purification and humidity management, you can create a home environment that is safe, healthy, and mould-allergy friendly.

When it comes to buying an air purifier, a common question arises: "Can this air purifier really clean the air in my entire room?" Unfortunately, the answer is not as clear-cut as manufacturers' claims might suggest. In an industry that lacks official standards in New Zealand, some brands overstate their product's capabilities, leaving you with a machine that's not up to the task. What's coming up: Air Purifier Room Sizes: Many manufacturers' suggested room size claims should not be believed. CADR Explained: Luckily we have an industry-standard measurement for air purifier effectiveness you should use instead. Unregulated New Zealand Market: Understanding the implications of the lack of official air purifier standards. Comparing Air Purifier Brands: The truth behind their CADR ratings and actual performance. Honourable Competitors: Acknowledging brands that maintain integrity with accurate figures. Unveiling the Truth Behind Air Purifier Room Size Claims The Heater Analogy: A Case of Selective Marketing Imagine purchasing a heater rated for spaces up to 50m². You place it in your living area, expecting it to create a nice cosy environment. Unfortunately the warmth falls short of what you'd expect. The heater, it turns out, is only powerful enough to increase the temperature by a couple of degrees in a space that size. To achieve the comfort promised, it would be better suited to a 20m² area. This scenario mirrors the tactics used by some air purifier brands: the product might technically work in the advertised room size, but the level of purification is inadequate for the intended use. What is CADR and Why Does it Matter? Clean Air Delivery Rate (CADR) is the amount of filtered air volume an air purifier delivers. Measured in cubic meters per hour (m³/h) in New Zealand, CADR is the industry standard way to judge effectiveness. However, if you can't find this number, it's possible the manufacturer is intentionally obscuring less-than-ideal performance. How to calculate the required CADR for a room To calculate the required CADR for a room, you'll need to know the room's size, ceiling height, and desired Air Changes per Hour (ACH). Multiply the room size by the ceiling height to get the room volume, then multiply the volume by the desired ACH (typically at least 3) to get the required CADR. A simple rule of thumb for CADR calculation As a quick rule of thumb, multiply the room's area (in square meters) by 7.5 to estimate the required CADR. This method provides a rough estimate for most residential situations. This is also in line with generally accepted standards overseas, such as AHAM in the USA and GB-18801 See further details here The Wild West of Air Purifier Standards in New Zealand A Market Without Regulation In the absence of official standards, air purifier recommendations in New Zealand are a mixed bag. Companies are free to claim almost anything, which can mislead well-intentioned customers. It gets more interesting when you look at these air purifiers being sold in other countries, where they often are required to use these standard ways of calculating room sizes. This suggests to us its not through ignorance that they inflate their figures here, but a deliberate attempt to mislead customers. Comparing Brands: The Good, the Bad, and the Ugly Based on using the standard calculations used overseas, there's some fairly stark differences between what some air purifiers claim, vs their actual effectiveness. Above are examples of some the worst ones in the NZ market, where their effectiveness is less than half of what they state. We've looked at dozens of models sold in NZ, and have been able to break down how much each brand on average inflates their room sizes compared to the benchmark (current as at November 2023). Our findings show while a handful of companies provide realistic room sizes in New Zealand, unfortunately most inflate their numbers by quite significant amounts!  *Based on standard calculations used overseas, dividing CADR by 7.5 to get effective room size coverage The Ugly: We couldn't even fit this on our chart! The prize for the most misleading unit goes to the i-air Pro. Which with a Clean Air Delivery Rate of 600m³/hour, claims to be suited for spaces up to 500m². This is a whopping 6.25x the room size it should be used in!

Finding the perfect balance of air purifiers for your home is key to ensuring that every breath is as clean and healthy as possible. Let's explore how to tailor your air purifying strategy to your home's unique layout and your personal needs. Key Points Versatility of Powerful Units: A single, powerful air purifier like the Blast can clean air in multiple rooms of an open-plan home when left running over time, similar to how one heater can warm multiple areas. Individual Needs Matter: Tailor the number and placement of air purifiers based on specific needs. For pet allergies, have purifiers in rooms where pets spend time. For localized allergies, one purifier in a high-use area may be enough. Strategic Placement: Position air purifiers centrally if possible for maximum efficiency, ensuring they're not obstructed by walls or furniture for optimal air distribution. Portability for Flexibility: Models such as the Sqair and SA600 offer easy mobility to provide clean air where it's needed most, adapting to your daily activities. Noise and CADR: Balance purifier performance with acceptable noise levels for your environment. Ensure the purifier's CADR (Clean Air Delivery Rate) is appropriate for the size of the room for effective air cleaning. Do I Need an Air Purifier in Each Room? The question of whether you need an air purifier in each room is like determining how many heaters you require during the chillier months. A powerful air purifier, like our Blast model, can make a difference in adjacent rooms over time, especially with doors open, allowing air to circulate freely. According to Smart Air, a larger unit can effectively clean a spacious apartment, making it a cost-effective option for open-plan layouts. Is One Air Purifier Enough? For many homes, especially those with an open plan, a single, powerful unit can significantly improve air quality in multiple connected spaces. The key is continuous operation, allowing the purifier to cycle through the air in one room and then pull in air from others. However, in homes with separate, closed-off rooms, you may still consider additional units to ensure that each space maintains optimal air quality. Understanding Individual Needs The number of air purifiers you need also depends on specific needs. If pet allergies are a concern and your pets have free range in the house, you might need a purifier in each room they frequent. But if allergy flare-ups are localised to where you spend most of your time, like the living room, one purifier in that space may suffice. Where to Place an Air Purifier Place your air purifier in a spot where it can distribute clean air evenly and isn't hindered by walls or furniture. It should be a minimum of 15cm off the wall. Central placement is typically recommended for maximum efficacy. But remember, even the most powerful air purifiers work best when they're not fighting against closed doors. The Practicality of Portable Air Purifiers Our portable models, like the Sqair and SA600, can be easily moved to where they're needed most, reflecting the dynamic nature of daily life. For larger spaces, our Blast and Blast Mini come with wheels, combining high efficiency with convenience. Tailoring to Your Home's Layout While a powerful purifier can impact multiple rooms, strategic placement is crucial. In a multi-story home or a layout with many separate rooms, several purifiers may be the answer to ensure comprehensive coverage. Considering Noise Level and CADR The noise level is a vital consideration, particularly in bedrooms or quiet spaces. Choose a purifier that balances performance with a noise level that's comfortable for you. Additionally, sizing air purifiers appropriately based on their Clean Air Delivery Rate (CADR) is crucial for efficiency. This is because many air purifiers sold in New Zealand unfortunately mislead customers with their quoted room sizes. Visit our Guide to Choosing an Air Purifier to understand how to match the purifier's power with your room's size. Wrapping Up The right number of air purifiers for your home blends the consideration of physical space, personal health needs, and practicality. With the correct placement and sizing, based on CADR, you can ensure your air purifiers work quietly and effectively, wherever you need them. Ready to breathe easier? Explore our selection of air purifiers, and let's find the perfect fit for your space and lifestyle.

You might have heard about air purifiers with ionisers or negative ion generators claiming to purify the air by releasing negative ions. But have you ever wondered, can these negative ions be harmful? The answer is, unfortunately, yes. Despite the apparent benefits, there's a dark side to these ion-generating purifiers which is often overlooked. In this blog, we dive deep into the unseen hazards associated with negative ion air purification. Key Points Summary: Negative ion air purifiers claim to clean the air by releasing negative ions which cause particles to fall to the ground. These ions can produce ozone, which is harmful to respiratory health. The Ministry of Education in NZ specifically requested air purifiers without ionisers due to the potential risks. Our range of air purifiers avoids negative ions completely, opting for safer, more reliable purification methods. Many air purifiers sold in NZ contain ionisers, sometimes labeled as plasma generators or other names. The Allure of Negative Ions Negative ions are often touted for their apparent ability to improve air quality. They adhere to airborne particles, causing them to become heavy and fall to the ground. This is also used to artificially inflate CADR (Clean Air Delivery Rate) values of some air purifiers. However, the truth behind these claims is more complex and potentially harmful. The Hidden Dangers: Ozone Production Negative ions can lead to the production of ozone. While ozone is certainly helpful up in the atmosphere for the planet, it's also harmful to human health, especially for individuals with respiratory issues. The Ministry of Education in NZ also expressed concerns about this technology, specifically requesting schools do not purchase air purifiers with ionisers for classrooms. The Reality of Negative Ions While there might be potential benefits associated with negative ions, the concentration produced by these purifiers is typically too low to provide any significant advantage. Moreover, the idea of particles falling onto your furniture, bed, or even yourself is quite unsettling. Because of this if you operate the ioniser function, you need to make sure to regularly wipe down and vacuum any surfaces in the area. Instead, it’s far more hygienic and efficient for these particles to be trapped in a HEPA filter. Misleading Marketing Tactics Many air purifiers in NZ carry ionisers, sometimes referred to as plasma generators or by other names. Keep an eye out for any 'special technology' in air purifiers, especially relating to ions. The misleading naming used can lead to unaware consumers purchasing products that might be harmful in the long run. Our Stand on Negative Ion Purification We are firm believers in providing safe, effective air purification solutions. Our range of air purifiers completely avoids the use of negative ions, ensuring a healthier environment for you and your loved ones. Thankfully Smart Air also share the same belief, so nothing in their range includes negative ions. If you already have an air purifier which generates negative ions, we recommend where possible ensuring this feature is turned off at all times. Wrapping Up: When it comes to ensuring clean, safe air, it's essential to choose a purifier that does not pose additional risks. We aim to provide reliable information to help you make an informed decision for the betterment of your indoor air quality.

The answer is a resounding yes! With a good HEPA equipped air purifier, you can significantly reduce dust accumulation in your home, creating a healthier and cleaner living environment. Key Factors to Reduce Dust Dust in homes can trigger allergies, asthma, and other health issues. Air purifiers with HEPA filters are effective in trapping dust particles. Consider CADR, noise levels, and affordability when choosing an air purifier. Other dust-reducing measures include regular cleaning and reducing fabric surfaces. Our range of air purifiers offers the ideal solution for a dusty home, balancing performance with affordability. Why is My House So Dusty? Even with regular cleaning, dust accumulation is inevitable. Dust comprises various particles including dirt, pollen, pet dander, and even tiny fragments of dead skin. The presence of fabric surfaces like carpets, upholstery, and curtains also contribute to a dusty home. Moreover, outdoor pollution from construction, vehicle emissions, and fireplaces can introduce additional particulate matter indoors. The Hidden Hazards: Impacts of Dust on Health Dust isn't just a nuisance; it can also be a health hazard, particularly for individuals who suffer from allergies or asthma. Here's how dust can affect your health: Allergies and Respiratory Issues Dust can trigger allergic reactions in sensitive individuals. Common symptoms include sneezing, runny or stuffy nose, and itchy or watery eyes. Moreover, dust can worsen existing respiratory issues such as asthma, making symptoms worse and potentially leading to more frequent or severe attacks. Asthma in Children and Adults New Zealand has one of the highest rates of asthma in the world. It affects around 1 in 7 children and 1 in 8 adults [Health Quality & Safety Commission NZ) . Dust, especially when combined with other allergens like pet dander or pollen, can be a significant trigger for asthma symptoms. Reducing dust levels in your home can help manage asthma symptoms and improve the quality of life for asthma sufferers. Dust Mites Dust mites are tiny creatures that thrive in dusty environments. Their droppings and remains are potent allergens and can trigger allergic reactions and asthma symptoms. An air purifier equipped with a HEPA filter can help reduce the presence of dust mites in your home by trapping dust mites and the dust particles that these mites thrive on. Skin Irritations Dust can also cause skin irritations, especially in individuals with sensitive skin or conditions like eczema. By reducing dust levels in your home, you may experience fewer skin irritations and a more comfortable living environment. The presence of dust in your home is more than an aesthetic issue; it's a health concern that warrants attention. Investing in an effective air purifier with a HEPA filter is a step towards a healthier home and improved well-being for all its occupants. The Hero: HEPA Filter HEPA (High Efficiency Particulate Air) filters are the gold standard when it comes to trapping airborne particles. They can capture up to 99.97% of 0.3 micron sized particles, which are much smaller than common dust particles. When it comes to battling dust, ensuring your air purifier is equipped with a HEPA filter is crucial. Evaluating Air Purifiers for Dust There's probably hundreds of different lists on the internet showing various models of air purifiers which can help reduce dust. So let's make it easier for you! Clean Air Delivery Rate (CADR) When shopping for the best purifiers for dust, considering the Clean Air Delivery Rate (CADR) is the most important factor. CADR indicates the volume of filtered air delivered by an air purifier. The higher the CADR, the more effective it will be in larger spaces. Make sure to compare different models based on their CADR and not just the room size recommendations from manufacturers - as these are often misleading. Noise and Affordability The quiet operation is essential, especially if the purifier will be running in bedrooms or living areas. Getting one which is too loud for you means you've just bought an expensive decoration. Moreover, affordability doesn't always mean compromising on quality. Our guide to choosing an air purifier can help you find a balance between price, performance, and noise levels. Our Top Picks for Dust Reduction Our range of air purifiers is perfectly tailored to meet the demands of a dusty home while ensuring you don't break the bank. With high CADR ratings and low noise levels, they are the go-to choice for creating a fresher living environment in New Zealand homes. Other Dust-Busting Measures Besides investing in a quality air purifier, there are other steps you can take to reduce dust in your home. Regular cleaning, using doormats to capture dirt from shoes, and maintaining your ventilation system can all contribute to a less dusty home. Wrapping Up Reducing dust in your home is a multi-pronged approach. A reliable air purifier with a HEPA filter forms a key pillar of this approach, complemented by regular cleaning and maintenance routines. With cleaner air, your home becomes a more comfortable and healthier place to live.

It's your best defense against pet dander, ensuring you, your family and friends breathe easier. 3. Pre filter: Catching the Fur Before air hits other filters, the pre filter catches larger particles, such as fur. This not only helps in keeping your home fur-free but also extends the lifespan of the HEPA filter. Finding the Right Purifier: It's All in the Details Choosing an air purifier isn't just about picking the priciest model. In fact the priciest are often some of the worst performers! When looking for an air purifier, factors like the Clean Air Delivery Rate (CADR), noise levels, and of course affordability come into play. CADR: Indicates the volume of filtered air delivered by an air purifier. The higher the CADR, the faster and more efficient the air purifier. Noise: Especially for bedroom purifiers, noise levels matter. No one wants a noisy machine disrupting their sleep. Affordability: Getting value for money is essential. An efficient air purifier doesn’t always have to break the bank. It can be hard working out what air purifier to look for, so we've put together a guide to help you.

When setting up a nursery for your precious little one, there's a checklist of essentials most parents are aware of - a crib, changing table, soft lighting, and comforting decor. But have you considered the air quality in the nursery? You might wonder, "Is an air purifier a good addition to my nursery?" The answer is a resounding yes! An air purifier can be a nursery necessity, safeguarding your child's health by filtering out harmful pollutants and ensuring a peaceful sleep. Key Points Summary: Childhood Asthma in NZ: Asthma is prevalent among children in New Zealand; an air purifier can help by removing airborne irritants. Negative Ion Concerns: Avoid air purifiers releasing negative ions as they can produce ozone, harmful to tiny lungs, especially concerning given some are marketed for nursery use in NZ. Combatting Odours and Allergens: Air purifiers tackle odours, pet dander, and outdoor pollution that seeps indoors, ensuring a fresh and clean nursery environment. Virus and Bacteria Reduction: Create a healthier space by reducing the presence of viruses and bacteria, crucial in a child's early years for better immunity. Noise and Light Considerations: Choose a quiet air purifier with minimal light emissions to maintain a serene, sleep-conducive nursery ambiance. Affordable, Effective Options: Our range of air purifiers offers high CADR (Clean Air Delivery Rate) and low noise levels without breaking the bank, tailored for New Zealand homes. Why An Air Purifier is Essential The early stages of life are certainly special. But this phase also brings vulnerability, especially to elements in the environment. The air that we breathe can either help us become strong and healthy, or harm us. Here’s a deeper look into why investing in an air purifier is an important consideration for your nursery: The Unseen Threats: Viruses and Bacteria While sickness is inevitable at young ages, there are ways to mitigate this risk. Air purifiers work to reduce the presence of viruses and bacteria in the air.  The Surprising Risk of Outdoor Pollution New Zealand's picturesque landscapes can be deceiving when it comes to air quality. Construction, vehicle emissions, and fireplaces contribute to outdoor pollution, including the dangerous PM2.5 pollutants, which can infiltrate your home, posing a risk to your little one. Pet Dander and Other Allergens Many families couldn't be without their furry companions, but pets can introduce dander and other allergens into the air. An air purifier can significantly mitigate these allergens, ensuring a fresher environment for your child. Take a look at our article to learn more about how an air purifier can help with pets. The Impact of Air Quality on Children Children, with their still-developing organs and faster breathing rates, are more susceptible to the adverse effects of poor air quality. This article by Smart Air sheds light on how air pollution can affect children even before birth, linking exposure to certain pollutants with birth defects. Air pollution doesn't spare the toddlers and young children either. It has been associated with neurodevelopmental disorders, childhood obesity, reduced lung growth, acute lower respiratory infections (ALRI) like pneumonia, asthma, and even childhood cancers. A staggering fact is that air pollution accounts for 1 in 10 deaths in children under five years old globally. Given these alarming facts, the case for a quality air purifier in your nursery becomes a compelling one. An air purifier equipped with a HEPA filter and a carbon filter can significantly reduce the exposure of your child to these harmful pollutants, providing a safer environment for them to grow and thrive. Choosing the Right Air Purifier Not all air purifiers are created equal, especially when it comes to safeguarding the health of our little ones. We've got an in depth guide here, but here are some crucial factors to consider: No Negative Ions It’s alarming to find a range of air purifiers in New Zealand marketed for use in nurseries that release negative ions. While they might sound harmless or even beneficial, these ions can produce ozone—a gas that’s harmful to the lungs, particularly the still-developing lungs of a child. In New Zealand the negative ion generation 'feature' is often marketed with different names including ionisers, plasma generators and more. HEPA Filters Are Your Friend HEPA filters HEPA filters are the gold standard in air purification, capturing over 99% of 0.3 microns sized particles - the hardest to capture. Ensure that the air purifier you choose has a genuine HEPA filter, and avoid products with "HEPA-like" filters, which are less effective. Consider the Noise and Lights You’ll want an air purifier that operates quietly to ensure your baby can sleep soundly through the night. Similarly, many air purifiers come with bright lights which could disturb your child's sleep. Look for models that operate under 30dB on low and allow you to turn off the lights (or like ours which have no lights!). Price and Performance Investing in a quality air purifier pays off in the long run. Make sure to look at the Clean Air Delivery Rate (CADR) when comparing air purifiers, and not the room sizes recommended by manufacturers as they can be misleading! Our Selection for Your Peace of Mind We’ve curated a range of air purifiers tailored for New Zealand homes, ensuring safety and effectiveness. Our selection of Smart Air purifiers avoids any models that release negative ions, operates at low noise levels and most importantly is affordable! For use in a nursery, we recommend either: Smart Air - The Sqair, or Smart Air - SA600 Wrapping Up Investing in a good air purifier is investing in your child’s health. As parents, we can’t control the outdoor air quality, but we certainly have a say in the air our little ones breathe indoors. Take a step towards creating a safer, cleaner environment for your baby, and breathe easy knowing you’ve made a sensible choice.

One of the most important factors in how well your air purifier will keep the air clean, is ensuring the filters are changed at the right time. But how often do you need to replace these filters and when do you know its time to change them? Let's delve into the answer, with a focus on our range of air purifiers from Smart Air. Key Points Summary The lifespan of air purifier filters largely depends on the air quality and the usage. HEPA filters typically last longer in relatively clean environments like New Zealand, as compared to more polluted areas. Carbon filters' lifespan can be tricky to determine due to varying levels of VOCs they tackle, but a very rough ballpark is every 3-6 months for our Sqair or SA600 and longer for models with more carbon like our Blast and Blast Mini. The absence of standardised testing across manufacturers makes comparing filter lifespans very challenging. Filter Fundamentals: HEPA and Carbon Filters Air purifiers primarily employ two kinds of filters: HEPA filters and Activated Carbon filters. While HEPA filters trap tiny particles, Carbon filters are your go-to for odour and gas absorption. Let’s explore their lifespans in a bit more detail. HEPA Filters: The Color Cue and Real-World Results HEPA filters work tirelessly to catch particles like dust, viruses, smoke and more. Over time, these particles accumulate, and the filter slowly becomes less efficient. A simple way to gauge a HEPA filter's lifespan is by checking its colour. A filter that’s turned from white to gray or black is ready for replacement. The lifespan of HEPA filters can significantly vary based on the air quality they are subjected to. The main factors determining lifespan are the amount of pollutants in the air and the surface area of the HEPA filter. Our SA600 and QT3 models include a filter replacement light which comes on after a set number of hours. This is a good cue to check if the HEPA filter needs replacing, or is still good to go for longer. Based on real-world testing, we have estimated the following lifespans for our models:  Model Lifespan (hours) Lifespan (months) QT3 (Travel) 1200 10 Sqair 2550 10 SA600 4750 19 Blast Mini Mk II 7800 32 Blast Mk II 10200 42   These figures are based on the HEPA filter lifespan calculator from Smart Air and use average pollution levels in New Zealand. This may increase or decrease depending on the pollution levels where you live. So, remember, the cleaner the environment, the longer your HEPA filter will last. Carbon Filters: The Smell Test Determining the lifespan of carbon filters is much more complex due to the immense differences in levels of VOCs seen in different areas. The more activated carbon a filter has, the longer it will last. This can be measured in the grams of carbon contained in the filter. Our models use actual pellets of carbon, extending the lifespan significantly compared to some other models out there. Carbon filters, when exposed to high levels of VOCs - as is common in newly renovated or constructed homes can become saturated and lose their effectiveness far quicker than under regular indoor conditions. To determine the effectiveness of your carbon filter, we recommend the “smell test”. It's a straightforward sniff test conducted on the carbon filter; if a sour or chemical odour is detected, it's time for a new filter. For more detail on performing this test, check out this link. Shifting Standards: A Word of Caution A noteworthy point is the lack of standardised testing for filter lifespans across manufacturers. A claimed lifespan of 12 months by one manufacturer might be based on just 4 hours of daily usage in low pollution conditions. It’s a murky area that makes comparisons very difficult. This is why we provide estimates in both months and in hours of usage. As a rule of thumb, filters with larger surface areas tend to last longer. The Perks of Separate Filters All our air purifiers are designed with separate HEPA and Carbon filters, allowing you to replace them at different intervals. This not only is cost-effective but also ensures each filter operates at its peak efficiency for longer. On the flip side, many air purifiers on the market come with 2-in-1 or 3-in-1 filter systems. While they might seem convenient, once one of the filters reaches the end of its lifespan, you are required to replace the entire set. This not only can be more costly in the long run, but also wasteful, especially if the other filters within the set may still be useful. Wrapping Up Ensuring the timely replacement of your air purifier's filters is essential for maintaining clean air in your home. With the right air purifier and regular filter replacements, you can breathe easy for years to come. Explore our range to find the perfect companion for your clean air journey.

With many homes equipped with heat pumps or air conditioning units, it's common for individuals to wonder if an air purifier is necessary. Both systems influence the air you breathe indoors, but they serve different functions. Let's explore if and why you might consider adding an air purifier to your living space. Heat Pumps/Aircon Units: What Do They Do? Primarily, heat pumps and air conditioning systems are designed to control indoor temperatures. They either cool or heat the air, ensuring a comfortable environment, especially during extreme weather conditions. One of the common misconceptions about air conditioners and heat pumps is that they bring in fresh air from the outside. In reality, most residential units simply recirculate existing indoor air. This circulation is crucial for managing indoor temperature but doesn't necessarily lead to improved air quality. These systems have built-in filters, primarily designed to trap larger particles to protect the machine and ensure efficient operation. However, the filtration system in most air conditioning units is very basic. While they can catch larger dust particles, they aren’t typically designed to handle smaller pollutants, allergens, or harmful microorganisms. Air Purifiers: A Deeper Dive into Air Quality Air purifiers are specifically designed to improve indoor air quality. Their multi-layered filtration systems can target a wide range of airborne pollutants, from large dust particles to microscopic allergens. Key Benefits of Air Purifiers: Superior Filtration: They can capture particles down to 0.01 microns and less! This includes pollen, mold spores, and certain bacteria and viruses. Odour and Chemical Neutralisation: Those equipped with activated carbon filters can absorb and neutralise unpleasant odors and volatile organic compounds (VOCs). Negative Ions: A Word of Caution Some models of both air purifiers and heat pump/aircon units come with ionisers that release negative ions. While these ions can help in precipitating airborne particles, there are concerns about them potentially generating ozone, which can irritate the lungs and is harmful to breathe in. Notably, our range of air purifiers does not generate negative ions, prioritising your health and safety. Do You Need Both? If you’re concerned about the purity of your indoor air, the answer is clear: having a heat pump or air conditioning unit isn't a replacement for an air purifier. While the former excels in temperature regulation, the latter is designed purely for air purification. Consider your specific needs: Are allergies or respiratory issues a concern in your household? Do you want to neutralise odours from cooking, pets, or other sources? Are you keen on reducing potential harmful chemicals or VOCs? If you answered 'yes' to any of these, an air purifier is a worthy addition to your home, even if you already have a heat pump or air conditioning unit. Browse our range of effective and affordable air purifiers here. Wrapping Up A heat pump or air conditioning system can make your living space comfortable, but if air quality is a concern, an air purifier is also required. Explore our selection of air purifiers and ensure not just a comfortable but also a healthy living environment.

Waking up to a stuffy nose, feeling congested, or experiencing exacerbated asthma symptoms can be early signs that the air quality in your bedroom needs improvement. Air purifiers are a proven way to enhance the air we breathe as we snooze. However, while on the search for cleaner air, the last thing anyone wants is a noisy machine buzzing through the night. This piece dives into the essential factors that contribute to making an air purifier both effective in purifying the air and quiet enough to ensure a peaceful night's sleep. Top considerations for your bedroom air purifier: Noise Concerns: A loud air purifier can be a deal-breaker for restful sleep. It's important to find a balance between effective air purification (CADR values) and low noise levels, especially on lower speed settings. Transparency in Performance Metrics: Many manufacturers may not provide clear CADR values at quieter settings or may overestimate the recommended room sizes. Transparency in noise level and CADR metrics is key to make an informed choice. What Does 'Quiet' Really Mean? For undisturbed sleep, experts recommend air purifiers with noise levels below 30dB. Some models, like The Sqair (23dB), SA600 (24dB), and Blast (29dB), fall within this quiet spectrum. Don’t Let the Lights Disturb You: The display lights on air purifiers can be disturbing in a dark room. Opt for simple models with no lights or displays which can switch off to maintain a dark, sleep-conducive environment. The Balancing Act: Noise Levels and Air Purification Efficiency The Noise Factor The tranquility of your bedroom is paramount. While some air purifiers may sound like mini-tornadoes on their max settings, finding a quieter option that doesn't compromise on air purification is key. CADR Values at Quieter Settings Lower settings often equate to quieter operation but may also mean decreased CADR (Clean Air Delivery Rate). It's a tad challenging since many manufacturers often skirt around providing CADR values at these quieter settings. Manufacturers can also be a bit too optimistic with their recommended room sizes. In reality, on lower speed settings, a few of these units might just about manage the air in your wardrobe! Transparency in Performance Metrics We believe in transparency and provide the noise level and CADR of all our products to help you make an informed choice: Model Speed CADR Space cleaned in 20mins Noise The Sqair High 315m³ 42m² 52dB Medium 180m³ 24m² 43dB Low 65m³ 9m² 23dB SA600 High 500m³ 67m² 53dB Medium 260m³ 35m² 39dB Low 135m³ 18m² 24dB Blast Mini High 740m³ 99m² 49dB Medium 450m³ 60m² 43dB Low 340m³ 45m² 36dB Blast High 950m³ 127m² 43dB Medium 680m³ 91m² 37dB Low 450m³ 60m² 29dB  So, How Quiet is 'Quiet'? For peaceful sleep, experts generally recommend noise levels below 30dB. To give you a helping hand: Model Noise level (low) The Sqair 23dB SA600 24dB Blast 29dB However, if you’re a fan of white noise (pun intended) and find it soothing, then you can afford to crank your air purifier up a notch without compromising on sleep quality. Lights Out for Better Sleep One often overlooked aspect of air purifiers in bedrooms is their displays. While many air purifiers come with display lights that can disrupt your sleep, our models are designed with simplicity and effectiveness in mind, devoid of any light-up displays. This ensures nothing comes between you and a peaceful night's sleep, maintaining a dark, serene environment perfect for rest. Wrapping it Up Selecting the right air purifier for your bedroom might take a bit of research, but the rewards — in the form of undisturbed, rejuvenating sleep — are well worth the effort. Ensure you consider noise levels, CADR values at those levels, and the option to have a light-free night. Here’s to breathing easy and sleeping even easier!

Whether it’s the lingering aroma of last night’s meal, the aftermath of a pet’s playtime, or the fresh but overpowering scent of new paint, these odours are never pleasant. So, can air purifiers help eliminate these unwelcome smells? The short answer is yes, but not all air purifiers are equally effective at tackling odours. The key is in the filter type. Air purifiers with activated carbon filters are especially good at removing smells. But what about HEPA filters? Let’s dive in and find out how different filters handle odours. HEPA Filters: The Dust Busters High-Efficiency Particulate Air (HEPA) filters are great when it comes to trapping airborne particles. From pollen to pet dander, these filters capture up to 99.97% of 0.3 micron sized particles. Impressive, right? But here's the catch: while they're great against dust and allergens, they don't have a direct impact on eliminating odours. Carbon Filters: Stink Stoppers Enter activated carbon filters. These are your go-to for removing nasty smells. At a microscopic level, activated carbon is porous and has an expansive surface area, making it perfect for adsorbing odours and gaseous pollutants. However, not all carbon filters are created equal. To effectively tackle strong odours, your air purifier should house actual pellets of carbon. Beware of many 2-in-1 or 3-in-1 filters available in NZ, which often just have a basic sheet, lacking the same odour-fighting ability. All of our air purifiers use separate carbon filters with real pellets (optional on Blast & Blast Mini) The effectiveness of carbon filters is largely determined by the amount of carbon they contain. A greater weight of carbon not only enhances the filter's odour-absorbing capacity but also extends its longevity in keeping your air fresh. The Common Culprits of Indoor Odours Cigarette Smoke: For homes with smokers, an air purifier equipped with a quality carbon filter is indispensable. Pets: Our furry friends bring joy, but sometimes they can also bring unwanted smells, especially from litter boxes or wet fur. Air purifiers can make a huge difference when it comes to keeping your house smelling fresh. Local Smells: Those near industries or specific areas, like certain suburbs of Christchurch still dealing with the impacts of that wastewater treatment plant fire, can benefit immensely. New Construction & Renovation: Fresh paint, new furniture, or even flooring, can off-gas chemicals like formaldehyde. A good air purifier can help minimise these harmful VOCs, protecting both your nose and health. The Invisible Threat: VOCs and Your Health Beyond mere odours, volatile organic compounds (VOCs) such as formaldehyde can pose genuine health concerns. Commonly found after new house builds or renovations, these compounds can irritate the eyes, nose, and throat, and even harm the central nervous system. An air purifier with a solid carbon filter can help improve the situation. However make sure to combine this with as much ventilation as possible and consider formaldehyde cookouts. Given the very high levels of VOCs present in these situations, we'd recommend our Smart Air Blast Mini (Or Blast) with added Carbon Filter. We've written an article about this specific issue, so make sure to check it out! Monitoring VOCs: Keeping Tabs on Invisible Threats Fortunately, there are advanced air quality monitors available that can detect and measure the concentration of VOCs in your environment. By having a reliable monitor in place, you can not only detect odours but also gauge the effectiveness of your air purifier and ventilation efforts in real-time. We have a range of air quality monitors which can measure VOC levels. Our units are the perfect combination of precision, user-friendliness, and affordability! Selecting the Right Odour-Combatting Air Purifier In addition to what we've mentioned earlier about choosing the right carbon filter, make sure to also consider the following factors: Power & Size: Ensure your air purifier matches the size of your room. One too small might not effectively clean the air, no matter how advanced the filters. Noise Levels: Especially if the purifier is for a bedroom or study, quiet operation is crucial. Price: Investing in a quality air purifier pays off in the long run, but that doesn’t mean breaking the bank. Check out our affordable range with high CADR and low noise levels For more detailed information, including why you shouldn't trust what manufacturers recommended room size, check out our comprehensive guide to choosing an air purifier.
