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.

Common questions
- Which filter fits the Blueair F3MAX?
- The Blueair F3MAX takes the Blueair F3MAX Particle + Carbon filter (Blue Pure 311i Max) (part F3MAX). Compatible filters made to the same specification also fit.
- How often should I replace the filter in my Blueair F3MAX?
- Every 6 months. Flow slows and performance drops off as the filter fills up, so it's worth doing on time.
- How do I fit the F3MAX in a Blueair F3MAX?
- No tools, a few minutes: 4 steps, listed on this page with the replacement video where the maker has one.
- What happens if I don't change it?
- The fan works harder for less airflow, and the carbon layer stops taking smells out well before the filter looks dirty.
- How do I reset the filter light?
- Hold the button on the top of the purifier until the filter light goes out, or clear it in the Blueair app.
