Wirecutter's top pick for large spaces, capable of cleaning up to 750 sq ft on high. Quiet for its power level and energy-efficient enough for all-day use.
If you have a large living room or open-plan space, the 211i Max is the one to get. Wirecutter tested it extensively and CNET's lab confirmed Blueair's performance claims — this is the rare case where expert consensus and real-world results align perfectly.
“If you need to purify the air in a space of 500 square feet or so, we recommend the Blueair Blue Pure 211i Max. It's extremely powerful, and in fact capable of delivering our recommended four ACH in spaces as large as 750 square feet”
