Common questions
- Which air filter fits the Blueair 108594?
- The Blueair 108594 takes the Blueair fabric pre-filter (Blue Pure 311) (part 108594). Compatible filters made to the same specification also fit.
- How often should I replace the air filter in my Blueair 108594?
- Every 12 months. Flow slows and performance drops off as the filter fills up, so it's worth doing on time.
- How do I fit the 108594 in a Blueair 108594?
- No tools, a few minutes: 3 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.
