    Just wondering how should we clean the filter?

  2. Rated 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!

    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;

    I don’t feel air flowing thru the Hepa filter. Is that normal?

    • Paddy Robertson (verified owner)

      Hi n_anand! We’ve run tests on the Cannon, and despite it feeling like not much air is flowing through the HEPA, there is still clean air coming out and its enough to clean a 300sft room! You can see Tom’s HEPA outlet test on Youtube showing how we’ve tested this: (this test was done on the DIY 2.0, the Cannon has an even stronger fan!)
