How many filters do I need for my blueair 211? null

Only one at a time. The filters last several months, and the light turns red to indicate when it’s time to change it.

A single replacement filter is needed.

Hi there! Thanks for reaching out! The 211 only takes 1 filter that you'll want to change after 6 months of use.
