Can Air Purifiers Remove Odours?

Can Air Purifiers Remove Odours?

Unpleasant odours can really put a dampener on your indoor experience, whether it’s the lingering scent of last night’s meal, a pet’s playful escapades, or the fresh but pungent smell of new paint in your living room. It leads to the inevitable question: Can an air purifier help remove these unwelcome smells? The short answer is yes, but with a caveat - not all air purifiers are created equal when it comes to odour elimination. The key lies in the type of filter they house. Particularly, air purifiers equipped with activated carbon filters are your best bet in banishing odours from your indoor environment. But what about the common HEPA filter, and how does it fare in the battle against the stench? Let's dive in.

Key Points Summary: Odour Elimination Essentials

  1. HEPA Filters Efficiency: Excellent for trapping airborne particles like dust and allergens, but not so effective in removing odours.
  2. Carbon Filters Efficiency: Your go-to solution for neutralising unpleasant smells thanks to their expansive microscopic porous surface.
  3. Choosing the Right Carbon Filter: Seek air purifiers with actual carbon pellets for superior odour-fighting performance, unlike many models in NZ with basic sheets.
  4. Common Odour Sources: Cigarette smoke, pets, local smells, and new construction or renovation projects.
  5. Dangerous VOCs: Beyond odours, volatile organic compounds pose health risks and require a robust carbon filter for mitigation.
  6. Monitoring VOCs: Employ air quality monitors to keep tabs on VOCs and gauge your air purifier's effectiveness.
  7. Other Considerations: Ensure your air purifier is suitably sized for your room, operates quietly, and is budget-friendly while offering high CADR (Clean Air Delivery Rate) and odour elimination.
  8. Product Recommendations: Explore top picks adept at odour removal tailored for New Zealand homes, offices and more.

HEPA Filters: The Dust Busters

High-Efficiency Particulate Air (HEPA) filters are stars 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: Odour Extinguishers

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 prowess. 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 and How Air Purifiers Help

  • 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 be a game-changer in maintaining a fresh ambiance.
  • 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 minimize 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. A robust air purifier with a solid carbon filter can help keep these at bay.

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.

Monitoring VOCs: Keeping Tabs on Invisible Threats

Volatile Organic Compounds, commonly known as VOCs, are a group of compounds that can become gases or vapours. Often, they are the culprits behind unpleasant odours and can also have adverse health effects in certain concentrations. To effectively combat and control these compounds, it's crucial to monitor them.

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 in real-time.

Our Qingping Pro air quality monitor, adept at detecting VOCs, seamlessly blends 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:

  1. Power & Size: Ensure your air purifier matches the size of your room. A device too small might not effectively clean the air, no matter how advanced the filters.
  2. Noise Levels: Especially if the purifier is for a bedroom or study, a quiet operation is crucial.
  3. 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

Wrapping Up: Making a Stink-Free Investment

While HEPA filters play an indispensable role in trapping particulates, odour removal is a job for the mighty carbon filter. Whether you’re battling strong scents or harmful fumes, ensuring your purifier is up to the task is key. As we navigate this odorous journey, it's worth investing in a device that ensures both a pleasant-smelling and health-conscious home.
