Details & Specs
The Blast Mk II is a durable air purifier with all-metal construction for long-lasting 24/7 use. It boasts the highest Clean Air Delivery Rate (CADR) in New Zealand (that we've seen!) at 950m³/hour, capable of purifying a 130m² space in just 21 minutes. Despite its power, it operates quietly at only 43 decibels, making it also the quietest high-capacity purifier available.
This purifier features an H13 HEPA filter that effectively captures 99.97% of tricky to filter 0.3 micron sized particles. It traps dust, allergens, virus-laden droplets including Covid and more. This makes it perfect for large areas such as hospitals, offices, retail, classrooms and more.
Additionally, it offers an optional Activated Carbon Filter to remove VOCs and odours, ensuring complete air purification. The Blast Mk II is your go-to solution for maintaining a clean and healthy indoor environment, whether in a home, office, or healthcare setting.

What the Experts Say
What Makes the Blast 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’s H13 HEPA filter boasts a massive 14.85m² of surface area - providing exceptionally high capacity to trap 99.97% of airborne particles. The larger surface not only boosts efficiency, but also extends lifespan, delivering consistent clean air for longer.

03. Unmatched Clean Air
With a CADR of 950m³/hour, the Blast delivers more clean air than any purifier we’ve found in New Zealand. It refreshes a 130m² space in just 21 minutes - perfect for open-plan living, offices, clinics, and classrooms.

04. Quiet Yet Powerful
Despite its industrial strength, the Blast operates at just 43dB on max - quieter than many smaller units. That means powerful purification without disrupting work, study, or patient care.

05. Durable, Sustainable Design
With an all-metal body, the Blast 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 Blast’s optional carbon filter contains 1.7kg of activated carbon pellets - one of the largest quantities in any purifier. This huge capacity makes it highly effective at removing VOCs such as formaldehyde and odours from paints, adhesives, new furniture, or heavy-use spaces.

07. Backed by Data, Not Hype
While many brands inflate coverage claims, Smart Air publishes real CADR and noise data. Independent testing shows the Blast is both the fastest and quietest large-capacity purifier in its class.
