Blueair Blue Pure 211i Max (Smart) review 2026
Swedish design with a fabric pre-filter, 635 sq ft coverage and the quietest high setting for its airflow — at a premium in filters
Is the Blueair Blue Pure 211i Max Worth It?
Best-looking large-room purifier. The 211i Max moves big-room air quietly and looks like furniture, which is why people love it. Five years of filters cost twice the Coway's, and there is not enough carbon to help with smoke.

- Washable fabric pre-filter in colours

- $80 filters every 6–9 months — most expensive to run
