Air pollution is a serious environmental and health issue. And it’s hard to escape – even our homes are filled with these dangerous microscopic particles. The Blast Mini's 3-stage filtration effectively traps dust, mould, pollen, and PM2.5 – the main cause of air pollution.

PM2.5 VOCs Smoke Viruses
Allergens Dust Pollen Mould

The Blast Mini gives out as much clean air as 2.2 Blueair 203s in a minute

That's a whole load of clean air!

It's quieter too

If it's more powerful than 2 Blueairs, it must be loud as heck, right?

It's actually quieter. Think of it as the strong, silent type. A huge fan and an oversized HEPA means that more clean air can be pumped out at lower noise levels. You’ll hardly notice while it’s running

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 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.

What's inside a Blast Mini?

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 and a filter. In this case, that fan and filter are just really big!

* Tests on the highest setting show that adding a carbon filter reduces airflow by 11%. This means that this purifier with both HEPA and Carbon filters will have an the airflow of1246m³/h and a CADR to 659m³/h

** The GBT 18801 standard recommends replacing HEPA filters after effectiveness drops to 50% of its initial value. Our lifespan tests were conducted in Beijing but the UK average lifespan is based W.H.O. air quality data. Our filter calculator gives you a rough guideline of lifespan based on how many hours a day you run your air purifier but note, the lifespan will vary depending on the pollution levels in your city and is based on running at top speed (it will last longer on lower speeds).

    Really pleased with these filters. Sturdy enough to survive in a class full of rowdy teenagers. Not too noisy and a nice stream of fresh air but not too breezy.

    I've had time to read and check here and there and finally chose this one. Delivery was quite fast and when the box arrived, I was surprised because it was so big. Fortunately, the original size of the item corresponds to the description and the item is very sturdy. It's quiet and it seems like the wind volume is quite strong.

    Fast delivery, assisted by a courier, good quality, unfortunately the coating has a little defect on the lid, but overall it's good, works well, complete with the adapter too

  11. 5 out of 5


    Seller is very responsive and delivery is very fast.

    According to expert testimony, this product is the safest product because it does not produce ozone and does not use ions. I researched +-2 days, then I really believe this product is the safest.

    Good luck, hopefully soon there will be a product that is smaller in size so that it is easy and light to move or travel with.

    I got to know the smart air brand after researching for an air purifier for my house which is on the edge of the Jakarta highway. After trying it, it turns out that its performance is not inferior to other expensive brands with more affordable prices.

    Top seller explains the product well

    It’s my second Smart Air air purifier (the first one is a Sqair) and highly recommended for excellent value for money and good performance. No frills - just remove from box and plug in to get clean air.

    Best value and filter around. stop buying the Mi purifiers!

    I bought Blast Mini purifier alarmed by severe pollution levels inside my house. Strategically placing it I could ensure clean air in 3 bedrooms during night. Any time at day I turn it on and it’s able to bring down pollution levels quickly in a large area of living room and adjoining dining area. I am happy with the product and highly recommend it. It does what it is designed for without any being.
    You would have to, however, invest separately into buying Air quality monitor to monitor AQI levels inside house as the filter has no monitors on it.

    I had been looking to purchase one reasonably priced purifier that had the ability to clean the air throughout my three-bedroom apartment. The Blast Mini arrived on a day with particularly poor air in Beijing, which in this case was great, as it presented an immediate opportunity to test its effectiveness.

    First things first- the machine was somewhat larger than other air purifiers I had seen in friends’ apartments, restaurants, or offices. However, this is perhaps not surprising, considering the size of the fan and its immense power. The machine was easy to move around as it comes with wheels, which are lockable, so you don’t need to risk injury when moving it between rooms. The purifier itself is very simple: there are just three speeds, which is honestly all you really need in terms of functionality. The first thing that struck me when switching it on was just how quiet it was, even on full speed. It was just about loud enough for you to know it was on and working yet quiet enough for the sound to blend in with background noise and to not disturb you.

    One customization to the machine was that I opted for a carbon filter, as they’re designed to capture gas pollutants. Like many apartments in Beijing, my apartment occasionally becomes swamped in a lingering sewage smell stemming from the drain. I hoped that the carbon filter may be prove useful in such moments. I noticed that occasionally leaving the machine on a low power mode while out definitely helped minimise the sewage smell.

    On the Blast Mini’s first evening, the PM2.5 levels outdoors read 172 while indoors read 43: still 4 times higher than a healthy level. I positioned the Blast Mini in the living room and the air quality monitor in the spare bedroom, which was adjacent to my bedroom. I set up the air quality monitor to record levels hourly, opened all the doors in the apartment and switched the machine on. I then headed to bed.

    I was very impressed to see these results in the morning ! Within an hour, the Blast Mini successfully reduced PM2.5 levels to 31. Within 6 hours, PM2.5 levels were down to 8. This was throughout the entire apartment!
    Considering the machine’s power and reasonable price tag, the Blast Mini is definitely a smart investment. Would recommend to anyone looking for an effective and affordable solution to indoor air pollution!

    I LOVE my Blast Mini. I bought it for the common area of my Dhaka (Bangladesh) apartment. Through our previous airpocalyptic winters here, I haven’t managed to get our PM2.5 solidly in the good range, despite using five additional Sharp purifiers throughout the apartment, which is a huge problem for me because I have young kids. I was lucky to buy my Sharp purifiers from a friend leaving Dhaka a few years ago so I got a good deal, though I’ve had to order replacement filters through Amazon India and pick them up at my in-laws house in Kerala when we visit. Now that Smart Air is in Dhaka (currently accessible through the Facebook Page Clean Air BD), it’s a game-changer. Apartments in Dhaka are huge, and very few people I know have a couple grand (or more?) to drop on purifiers to fully secure their indoor spaces. Plus, people love their cool winter air, which means opening the window sometimes in winter and letting the pollution waft in. The Blast Mini sits right in the center of my apartment, near both the kitchen and the common area where my kids spend most of their time. With this set up, the air inside is always in the green and I can breathe easy knowing my kids are protected. My husband really appreciates the lower noise of the Blast Mini compared to the Sharp purifiers (poor guy…). Plus, I think it looks super nice and you can even set stuff on top of it if needed (convenient!). Thank you Smart Air for your brilliance.

    Very big machine suitable for people with space. The sound is very quiet. Importantly, the price is not high. After using it, the dust issue in the house is noticeably better. good value for money
