Details & Specs
The Blast Mini Mk II is a durable air purifier with an all-metal construction, ensuring longevity and robust performance. With an impressive Clean Air Delivery Rate (CADR) of 740m³/hour, it can efficiently clean an 85m² space in just 17 minutes, making it perfect for larger areas like offices, classrooms, and hospitals.
Despite its powerful cleaning capacity, it operates quietly, maintaining a maximum noise level of just 49 decibels, ensuring minimal disruption.
Equipped with an H13 HEPA filter, the Blast Mini Mk II captures 99.97% of the most challenging to filter, 0.3 micron-sized particles. It traps dust, allergens, virus-laden droplets including Covid and more. This makes it ideal for demanding environments that require high standards of air quality, like offices, clinics and more.
For those dealing with volatile organic compounds (VOCs) and odours, the optional Activated Carbon Filter effectively removes unwanted chemicals and smells.

What the Experts Say
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.
