How the Blast protects you from air pollution

Air pollution in Bangladesh is a well-known problem, with Dhaka’s air quality index reaching very unhealthy levels in 2019. The Blast’s massive  H13 HEPA filter effectively traps dust, mold, pollen, and PM2.5 – the main cause of air pollution.









Powerful and efficient – your lungs will have a “Blast”!

The Blast is simple. It’s a fan and a filter, packed into one box. But it’s also simply powerful. We’ve tweaked every part of this machine to give it the max performance for the money.

Over 200 tests

Alright, alright, we staged this photo. But aeronautical engineer Paddy really did run over 200 tests on noise, particle capture, wind speed, and power usage. That’s how it can be strong and yet quiet. has days and days of raw room test data for the nerd curious!

The Blast gives out as much clean air as 3.4 Blueair 203s in a minute

That’s a whole load of clean air!

It’s quieter too

If it’s more powerful than 3 Blueairs, it must be loud as heck, right?

It’s actually quiet. Think of it as the strong, silent type.

The Blast contains a huge fan, and an oversized HEPA, this means that it can pump out more clean air at lower noise levels.

H13 Grade HEPA Filter

Chosen among 10 different tested HEPA materials. Effectively filters 99.95% of PM2.5, dust, pollen and viruses.

Blast Activated Carbon Filter

Add a carbon filter to your Blast if you need to remove odours. Absorbs formaldehyde, volatile organic compounds (VOCs) and other harmful gases.

Covers up to 1400 sft

With that type of muscle, the Blast 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.)

What’s inside a Blast

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.

  1. 4 out of 5



    1. Large air cleaning capacity.
    2. Works almost silently even at highest fan speed. Sometimes I have to put my hand 2-3 inches away from it to see if it works.
    3. Expensive but costs less than other large air purifiers with same cleaning capacity.
    4. Prefilter is thicker than what comes in Philips and traps a lot of dust. The HEPA and carbon filters were relatively clean when I changed them.

    1. Sometimes the power cord behind it gets loose and it turns off until pushed back in. Since it’s mostly silently, hard to know when that happens.
    2. There should be a better design than opening 3 screws to take out the pre filter. I have swapped the side holding metal strips with the top and bottom ones. It’s not a good fit but this way I have to only open the top screw to get the pre filter out.
    3. Filters are heavy. It’s hard for a single person to change them, try to get 2 persons to change it. Once I was changing it on my own. The loose power cord behind, unknown to me fell on the bottom frame. The filters with the front frame wouldn’t fit, since there was a power cord blocking the frame at the back. After some time the front metal frame with carbon filter and HEPA filter fell on my toe, which caused a subungual hematoma.

    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 ?
