How long it lasts
Replace every 6 months (6–9 months on RealTrack (app tracks actual use)) — the app reminds you.
After fitting: 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 of the filter.
