The Blast Mk II is our simplest yet most powerful air purifier. It’s a powerful fan and huge HEPA filter  – all packed into one minimalist box.

Backed up by Open Data Tests

Alright, this photo is staged! But aeronautical engineer Paddy really did run over 200 tests on noise, particle capture, wind speed, and power usage. Because of this, the Blast Mk II can be a powerful yet quiet air purifier. And you don’t have to believe us. All this is backed up by thousands of hours of open data in our Clean Air Blog.

The Blast Mk II gives out as much clean air as 1.54 Coway AirMega 400S in an hour.

That’s a whole load of clean air for large spaces!

Don’t break the bank

Our purifiers (and filters!) are the most cost-effective in the world. Save $75 on your clean air annually, when compared to Coway AirMega 400S’ filters. At Smart Air, we firmly believe that clean air shouldn’t be a luxury. Many purifier companies stuff their purifiers with unnecessary gimmicks to drive up the prices. We too were subject to the exorbitant prices of clean air.

The Story of Smart Air

Subscribe to Smart Air on YouTube Smart Air Youtube

That’s why we simplify our purifiers to the bare essentials – a fan and a filter. Clean air at the simple turn of a dial.

Silent as a Sea Breeze

The Blast Mk II’s powerful fan and refined engineering give you extra-quiet clean air that sounds like a gentle sea breeze.

A huge fan and an oversized HEPA mean that the Blast Mk II can pump out more clean air at lower noise levels. With its quiet design, the Blast Mk II is ideal for those sensitive to noise, or those just wanting a good night’s sleep. Unlike most air purifiers for large spaces, the Blast Mk II  is the strong, silent type.

Use it anywhere

The Blast Mk II air purifier covers large spaces up to 130m², or 1400 sqft. With that type of muscle, the Blast Mk II can cover big apartments, offices, or gyms.

(Or run it on low in a normal apartment, and you’ll have the quietest clean air on the block.)

Use the Blast Mk II in your:

Bedroom

The Blast Mk II’s whisper-quiet operation lets you enjoy clean air and peaceful sleep.

Living room

The Blast Mk II’s powerful filter can purify large apartments of allergens and viruses.

Office

Clean air while you work. Don’t let your homes be the only spaces with clean air.

Hospital

The Blast Mk II’s H13 HEPA filter makes it suitable for health facilities, like hospital rooms or clinics.

Choose your filter

The Blast Mk II air purifier offers 3 levels of protection to filter out a range of particles and allergens. Its H13 HEPA filter is ideal for capturing allergens and viruses, making it the perfect purifier for those with allergies and sinus problems.

1. Pre-Filter
  • Removes dust, lint, pet fur and human hair
  • Captures larger particles so your HEPA filter lasts longer

2. Carbon Filter
  • Add a carbon filter to your Blast Mk II if you need to remove odors
  • Absorbs formaldehyde, volatile organic compounds (VOCs) and other harmful gases

3. H13 HEPA Filter
  • Effectively filters 99.95% of PM2.5, dust, allergens and viruses
  • Tested to be effective for 5280 hours, just shy of 2 years if used 8 hours daily

Why Hospitals Love the Blast Mk II

Clean air is especially important for crowded hospitals and medical facilities. The Blast Mk II’s H13 grade HEPA filter traps 99.95% of viruses and bacteria, making it extremely effective for use in health facilities. Hospitals around the world are using Smart Air’s powerful air purifier to help filter out the virus in their facilities, and the Blast Mk II is popular in major hospitals around the world for COVID-19 protection.

The Blast Mk II against COVID-19


A common concern is whether HEPA filters can filter viruses like the COVID-19 coronavirus. HEPA filters removes particles greater than or equal to 0.3 microns, but virus particles are smaller. The coronavirus measures 0.06 to 0.14 microns in diameter. So are air purifiers powerless against viruses? Actually, HEPA filters actually work great at capturing viruses. This is because a HEPA filter works not like a net, but through a process called diffusion. Learn more about how this works here.

Which Purifier Should I Buy?

The Blast Mk II FAQs

Are Smart Air purifiers better than other air purifiers?

Smart Air purifiers use the same cleaning principle as most other air purifiers. The technology behind air purifiers is not complex, and readily available.

However, Smart Air is the only air purifier company committed to transparent communication through open-data. We avoid overcomplicating our air purifiers with high markups and marketing gimmicks. Smart Air purifiers are honest, data-backed, and streamlined to do one thing: clean air.

And because we don’t overcomplicate things, our purifiers are some of the quietest and most energy-efficient on the market.

Can Smart Air’s purifiers filter COVID-19?

HEPA filter air purifiers like Smart Air’s have been shown to filter out COVID-19 viruses, and lower transmission. View the CDC data on how HEPAs reduce COVID-19 transmission here.

What pollutants does the Blast Mk II filter?

Smart Air purifier’s HEPA filters capture many types of particulate air pollution, including nanoparticles as small as 5 nanometers (1/10th the size of COVID-19) to 30 μm (the size of pollen). The whole range includes viruses, bacteria, PM2.5, PM10, pet allergens, dust, and mold.

An additional activated carbon filter can be added on top of the HEPA filter in all of Smart Air’s products. The carbon filters can absorb VOCs (Volatile Organic Compounds) such as formaldehyde, paint thinners, petroleum fuels, or dry cleaning agents. Carbon filters also remove odors. Learn which filters you need in our in-depth guide on air purifier filters.

Where should I position my Blast Mk II air purifier?

Smart Air tests show the position of an air purifier in a room does not matter, as long as: 1) The air purifier is at least 6 inches (15 mm) away from the wall. 2) The air purifier is strong enough for the room it is in.

How to know when it is time to replace the Blast Mk II’s HEPA filter?

We recommend replacing the Blast Mk II

filter every 21 months. But the truth is the exact time depends on many factors such as the number of hours used and local pollution levels. The most accurate way to determine when to replace a HEPA filter is to use an air quality monitor. Learn More: How to use an air quality monitor to test a HEPA filter

    Anna

    We couldn’t be happier with our Blast. I work in a large apartment that has been converted into an office. Some of my co-workers have small purifiers in their closed offices, but my desk is in the 70m2 open-plan living room and the front door is often cracked open to run cables back and forth so I knew we needed a powerful unit. The Blast arrived just in time for the recent Beijing sandstorm (2000+ AQI outside) and it was down to 30 AQI within half an hour. I couldn’t believe it, nor how quiet the machine is. It’s almost silent, even on the highest setting. We’re in love!

    Everything from the shipping packaging, design, quality of build is exceptional. Being unable to see a product in-person can be daunting. I cannot be more pleased with the Smart Air Blast.

    Shipping was quick to my office in Xi’an. Arrived sooner than promised.

    I am very impressed with the construction — sheet steel is thick, finish is uniform, 3-speed fan is quiet — quiet enough for an office setting even at the highest fan speed.

    The Blast is so simple that it hardly needs any instructions. I had it unpacked and running in less time than it took me to configure the AirVisual Pro Air Pollution Monitor. I also got the monitor in order to know how bad things were in the office. When I unpacked the monitor, the air quality in my office was exactly the outdoor reading. What I like about the monitor is that it exports data, so I could see how the Blast was doing. It cleared the PM2.5 matter from a 3.5mx6mx2.8m office in less about an hour. I plotted readings. (yes, I am a data geek)

    These are awesome. We have one in our bedroom at full blast constantly and have never considered it loud at all. We watch films fine and don’t even notice it. And we sleep in perfectly clean air… seems like a pretty good deal to me! Thanks guys!

    I’m not sure what everyone is talking about, referring to noise etc. the unit is pretty damn quiet…
    thanks team, I will recommend your product to other ex-pats like myself. Cheers ?

    Love it!
    To say the least. As a new ex pat in China, buying an air purifier could have been a real headache, but Smart Air helped immensely. I did my research and it made sense to choose SmartAir. It arrived quickly as it had to be shipped. A couple of days after using it a friend with an egg that reads air quality stopped by and honestly, I was concerned. Even told my wife perhaps we are better off not knowing because if we don’t like the results, what could we do?
    That wasn’t a worry because the results were better than expected. Phew.
    I know quite a few people who have bough purifiers since they moved here and I am 100% confident I made the best decision to purchase from Smartair. Some who already bough a purifier are considering buying a SmartAir because their more expensive machines are not cleaning their air nearly as well.
