Replacement Filters:

Allergies

Large H13 HEPA filter and a powerful CADR quickly trap pollen, dust mites and mould spores - reducing sneezing, itchy eyes, and other allergy symptoms in even large spaces.

asthma inhaler icon

Asthma

The Blast Mini delivers strong, consistent airflow through genuine H13 HEPA filtration. No ionisers or ozone - just safe, effective clean air for sensitive lungs.

dust icon

Dust & Dust Mites

High CADR ensures fast air changes across large rooms, capturing dust and mite allergens before they settle. The oversized HEPA filters hold more, lasting longer.

mould icon

Mould

While purifiers can’t remove mould at the source, the Blast Mini’s high-output H13 HEPA filter captures airborne spores, ideal for those with mould sensitivities.

Pets

From pet dander to odours, the Blast Mini's genuine HEPA filter captures fine hair and dander, while the optional activated carbon filter absorbs smells for a fresher home.

Smoke

Woodburners and urban air bring fine particles that linger indoors. The Blast Mini’s strong CADR plus optional carbon filter help remove both smoky particles and odours.

virus icon

Viruses

H13 HEPA filter captures airborne viruses, including COVID-19. With its high CADR, the Blast Mini delivers more air changes per hour, even in large office spaces or classrooms - reducing the time viruses stay suspended in the air.

Smells & VOCs

Optional carbon filter absorbs odours and gases like formaldehyde (from furniture/renovations) and nitrogen dioxide (from cooking or traffic), keeping air fresher and safer.

What the Experts Say

House Fresh

“This beast of an air purifier makes light work of clearing airborne pollutants in large spaces … The Blast Mini outperformed all the units we’ve tested so far. It’s not loud, incredibly easy to use thanks to its one-dial operation, and built to last with a durable metal body and smooth-rolling wheels."


"Our sound tests showed it is incredibly quiet, considering how powerful its fan is … After our performance tests, the Blast Mini took the #1 spot as the fastest unit at cleaning the air and the #1 spot as the quietest large air purifier."


"All in all, I really like what Smart Air is trying to achieve with the Blast Mini. It’s easy to operate, built to last, and the most effective large-space purifier we’ve ever tested.”

What Makes the Blast Mini Different?

01. No Ionisers

Ionisers/negative ions can create ozone, a lung irritant that can make asthma and allergy symptoms worse. They also inflate CADR readings, giving a misleading picture of performance. The Blast Mini skips the gimmicks - just powerful, proven H13 HEPA and optional carbon filtration for safe, reliable clean air.

02. Huge HEPA Filtration

The Blast Mini’s H13 HEPA filter has 7.05m² of surface area - many times larger than what’s found in standard purifiers. That means it captures 99.97% of particles like dust, smoke, and viruses, while lasting longer and maintaining strong airflow before needing replacement.

03. Powerful Clean Air

With a CADR of 740m³/hour, the Blast Mini refreshes up to 85m² in just 17 minutes. That’s more clean air, faster, making it perfect for open-plan living rooms, offices, classrooms, and clinics where large volumes of air need to be cleaned quickly and continuously.

04. Quiet Yet Mighty

Despite its industrial-strength motor, the Blast Mini runs at just 36dB on low - quieter than a library. Even at maximum speed, it reaches only 49dB, making it one of the quietest large-space purifiers available. Clean air without disrupting work, study, or rest.

05. Durable, Sustainable Design

With an all-metal body, the Blast Mini is made to last longer than plastic alternatives and is more sustainable too. Built on smooth-rolling wheels, it’s easy to move between rooms or across larger spaces, combining industrial durability with everyday practicality.

06. Packed Carbon Filtration (Optional)

The optional carbon filter holds 700g of activated carbon pellets - far more than typical filters that use only a thin layer. This sheer volume allows it to absorb more VOCs such as formaldehyde and odours, from cooking and traffic fumes to light renovations and new furniture.

07. Backed by Data, Not Hype

Many purifiers inflate coverage numbers without real CADR testing. The Blast Mini is different. Independent tests show it’s both the fastest and quietest large-space purifier reviewers have ever tested, with every performance claim backed by published data.

Blast Mini FAQs

The carbon filter is optional. To keep the Blast Mini cost-effective, it comes standard with the large H13 HEPA filter (for capturing particles, viruses, allergens). If you need protection from VOCs and odours - such as during light renovations, with new furniture, or for heavy cooking then you can add the carbon filter for stronger coverage.

No. Many purifiers add cheap sensors that look good on paper but often misread pollution levels and turn off too early. The Blast Mini is built for reliability and simplicity, with 3 manual fan speeds. For accurate readings, we recommend pairing it with a dedicated air quality monitor. Most users run the Blast Mini whenever people are present - or 24/7 in offices, classrooms, or clinics.

HEPA filter: Expect around 32 months of life with 8 hours/day of use in NZ conditions. Replace when the filter turns grey/black or when airflow drops noticeably.

Carbon filter: Lifespan varies depending on odour/VOC levels. Do the “smell test” - if it develops a metallic/acidic smell, it’s saturated and needs replacing.

Yes. H13 HEPA filters capture 99.97% of particles at 0.3 microns, but they’re also highly effective below that size. Thanks to Brownian Motion, ultrafine particles as small as 0.01 microns - including viruses like Covid, are trapped by the fibres. This makes the Blast Mini an excellent choice for reducing airborne viruses in large, shared spaces.

Yes. Once you’ve set your preferred fan speed, the Blast Mini remembers it. When power is restored via a smart plug, timer, or wall switch, the unit restarts at the same setting. No app, Wi-Fi, or extra setup required.

At NZ’s average $0.25/kWh, running costs are:

  • Low: ~$0.29/day
  • Medium: ~$0.49/day
  • High: ~$0.73/day

(24 hours continuous use).

Despite its size, the Blast Mini is impressively quiet. On its lowest setting it runs at just 36dB (library-level quiet), while even at full speed it reaches only 49dB. This makes it one of the quietest large-space purifiers available.

With a CADR of 740m³/hour, the Blast Mini can refresh an 85m² space in just 17 minutes (1 air change). It’s ideal for classrooms, offices, clinics, or large open-plan homes where rapid and consistent clean air is essential.

The Blast Mini ships via freight on a small pallet from Christchurch, with full tracking provided. Delivery is typically 2–4 business days locally and 3–5 business days elsewhere in NZ after ordering.

Yes. The Blast Mini comes with a 1-year manufacturer’s warranty, plus full coverage under the Consumer Guarantees Act (1993). Thanks to its robust all-metal build and simple design, issues are rare - but if anything goes wrong, you’re supported locally.
