What’s inside a Blast Mk II
Purifier companies can make obscene profits when most people don’t understand how purifiers work. Here’s the honest truth: a purifier is a fan + a filter. In this case, that fan and filter are just really big.
Technical Performance Overview
Which Purifier Should I Buy?
Choosing the right air purifier can be difficult for first-time buyers. Here’re some important things to consider:
1. Know Your PurposeDo you have any particular needs? HEPAs are enough for allergies and asthma, but recent renovation may require a carbon filter.
2. Know Your SizeThe Sqair purifier is ideal for bedrooms, but larger spaces like offices or hospitals may require the more powerful Blasts.
3. Know the CostsThe main costs of air purifiers are filter replacements. Different purifiers have different HEPA lifespans and costs.

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.
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 purifiers’ HEPA filters capture many types of particulate air pollution, including nanoparticles as small as 5 nm (1/10th the size of the COVID-19 virus) 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

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!

Great service, delivered promptly before expected. Seriously notice the difference when I plugged it in and it is only summer.
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.
