FAQs
What filter does the Blueair 211i Max use?
The Blue Pure 211i Max uses its own replacement main filter, which combines particle and activated carbon layers, offered in versions such as the AllergenBlock filter. It does not use the older Blue Pure 211+ filter. Check the model label on your unit before ordering.
How often should I replace Blueair filters?
Blueair generally recommends replacing the main filter about every 6 months with regular use, sooner with heavy smoke, pets or continuous high-speed use. The fabric pre-filter can be washed or vacuumed as needed. Smart models show filter life in the Blueair app.
Can I wash a Blueair filter?
Only the fabric pre-filter is washable. You can machine wash it on a gentle cycle or vacuum it, then let it dry before reinstalling. The main particle and carbon filter is not washable and must be replaced. Washing it would damage the media.
