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.

Blueair Blue Pure 211i Max Pros & Cons

Pros
  • Cleared our room in 11 minutes on high at only 50 dB — quietest for the airflow
  • 23 dB on low
  • Washable fabric pre-filter in colours
  • App with sensor and filter tracking
Cons
  • $80 filters every 6–9 months — most expensive to run
  • Little carbon; not for smoke or smells
  • HEPASilent is not a traditional sealed HEPA
