A highly effective yet low-cost DIY air purifier
Our DIY 1.0 Air Purifier is a simple and low cost yet effective DIY air purifier that eliminates PM2.5 and PM10 particles.
Our tests show that the DIY 1.0 can remove up to 82% of PM2.5 particles from a 150sqft room, all for less than Rs.3000
How does it compare to expensive purifiers?
We tested this simple DIY air purifier against some of the biggest brands on the market, and found that the simple DIY filter 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 DIY air purifier in action.
How often should I change my DIY’s HEPA 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 DIY 1.0 air purifier 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 and ship Smart Air verified filters for as little as Rs.1300.
