How long it lasts
Usually every 6 months. The filter light is a reminder, not a water-quality sensor.
After replacing: Press and hold the button until the filter light goes out (about 5 seconds).
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 501DPF?
- The Blueair 501DPF takes the Blueair Classic 500/600 series DualProtection filter set (part 501DPF). Compatible filters made to the same specification also fit.
- How often should I replace the filter in my Blueair 501DPF?
- Every 6 months. Flow slows and performance drops off as the filter fills up, so it's worth doing on time.
- Where can I buy the 501DPF in Australia?
- We track 2 Australian sellers for the 501DPF; the lowest listed price when we last checked was A$137.25 at Amazon AU. Prices are re-checked daily and dated on this page.
- How do I fit the 501DPF in a Blueair 501DPF?
- 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?
- Press and hold the button until the filter light goes out (about 5 seconds).
