“How long do the filters last before having to be changed?”

1-2 of 2 Answers

• Change the main filter every 6 months depending on the operating conditions. The outside prefilter (sleeve) depends on use. I change our prefilter every month. The prefilter can be washed which is nice. The device comes with two prefilter (sleeves).

• Thank you for your interest in Blueair. We recommend changing the filters every 6 months and the units have a filter timer that will let you know once the time has passed and a filter change is needed.
