How long it lasts
Usually every 6 months (6–9 months on RealTrack (app tracks actual use)). The app reminds you when it is due.
After replacing: Hold the button on the top of the purifier until the filter light goes out, or clear it in the Blueair app.
Flow slows and taste drops off as the filter fills up. Changing on time is the whole point.
Not due yet?
Get a nudge when your filter is due — it's every 6 months. One email two weeks before, no newsletter. Manage or stop it anytime.

- No tools, a few minutes: 4 steps, listed on this page with the replacement video where the maker has one.
