Clean Air is not a Luxury
Our Original DIY Air Purifier is a simple and low cost yet effective purifier that eliminates PM2.5 and PM10 particles.
Our tests show that the Original DIY can remove up to 82% of PM2.5 particles from a 150sqft room, all for the under Rs.4000
How does it compare to expensive purifiers?
We tested this simple DIY purifier against some of the biggest brands on the market, and found that the simple DIY performed almost just as well as purifiers costing over 20 times as much!
Does it really clean the air?
Tom the founder of Smart Air and a professor at the University of Chicago tested this using a laser particle counter. What he found was that even low cost filters and fans can provide clean air. Watch this video to see the test he did.
How often should I change my filter?
We recommend replacing your filter after 90 days of use at 8 hours a day at the latest. That’s maximum 720 hours in total. We ship replacement HEPAs starting at Rs.1300 from our store.
Why 90 days? Smart Air co-founder Gus tested a single HEPA on his Original DIY for 200 days in Beijing to see how long it would last in real Beijing air. After 100 days of use at 8 hours a day, effectiveness dropped 4%. After 200 days of testing, Gus’s dirty filter was only removing half the particles in the room.
India’s air is on average more polluted than Beijing’s air, so in India we recommend replacing the filters sooner, at 90 days or 720 hours.
We know that buying new HEPA filters is a significant recurring cost, so we do our best to keep prices low.
