Get rid of air pollutants for a whole year using our super awesome Cannon DIY Air Purifier. We’ll send you a Cannon fan, 1 HEPA filter with pre-filter attached, and an elastic strap. That’s all you need to breathe easy quickly.

Please note that there is some assembly required. The legs of the Cannon have to be screwed on and there’s a handy screwdriver in the package. Then the HEPA filter has to be slipped under the elastic strap. Scroll down to see our video that explains the assembly process. If this is too complicated for you, we can come over and assemble your fan for a small fee. Send us a message and we'll figure out a time that works.

How effective is the Cannon DIY Air Purifier? From our testing, we’ve seen that the Cannon is 96 – 97% effective against PM2.5 in a room size of 250 sq-ft. So the Cannon works in a room about twice as large as the Original DIY. The shape of the fan, with a large tube between the fan blades and the HEPA makes much more air go through the HEPA rather than deflect to the side or back.

The Cannon DIY's CADR (smoke) rating is 289 CMH (m3/hr).

Just so you know, our H13 HEPA filters are CE certified:

CE Certified

CE 2047 according to PED (97/23/EC). Certified by Regal Quality Registrars, Inc, UK. Made in India with imported HEPA material.

    Just wondering how should we clean the filter?

  2. 5 out of 5


    Works as well or better than BluAir / Sharp units I have. Economical and convenient availaibility of replacement filters. Keep up the great work!

    Can feel the difference in the air quality.

  4. 3 out of 5

    (verified owner):

    Its doing the job of cleaning the air — AQI drops from 150+ to 55-65, PM2.5 goes under 15 as per Laser Egg monitor within 2-3 hours with window slightly open for ventilation (AQI drops below 30 if room is tightly closed, though this is not recommended) — on “high” fan (medium and low fan speeds are useless); BUT the design is not kid friendly — strap provided is not what is sold separately, becomes lose often, extremely inconvenient to put back on; If filter is removed, the fan gets exposed which is dangerous; A lot of air is being deflected back as air is pushed on to filter — a pull approach would have worked same/better with a less powerful silent fan — it does make significant sound in high speed; I ordered extra pre-filters and face masks, for which delivery charge was added-up, even though they didn’t add any extra weight to consignment;
