HEPA filters (or High efficiency particulate air) are filters that capture at least 95% of particles. The ones we use capture 99.9% of particles, including the really tiny ones.
We recommend replacing your filter after 140 days of use at 8 hours a day at the latest. That’s maximum 1000 hours in total. We ship replacement HEPAs starting at 75RMB from our store.
Why 140 days? Smart Air co-founder Gus tested a single HEPA on his Original DIY for 200 days 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.
We recommend changing your filter after 1000 hours. You can use this number to calculate how often you need to change your filter based on how often you have your purifier running. For example, if you keep your purifier on 12 hours a day, we’d recommend replacing your filter after 60 days.
We know that buying new HEPA filters is a significant recurring cost, so we do our best to keep prices low.
We tested a 30RMB filter from China and compared it to our own filters. We found the difference in effectiveness to be severe so we recommend avoiding unknown HEPA filters that appear too good to be true.
