Blueair · SPECIFICATION PROFILE
Blue Pure 211i Max
Its higher smoke-CADR figure makes it a relevant larger-room comparison candidate. Placement, connected rooms and tolerable operating speed still matter.

What to check before choosing
No additional model-specific discrepancy is recorded here. That is not a guarantee that every source claim is consistent or complete.
Listed room coverage depends on the air-change and ceiling-height assumptions. Minimum noise should not be paired with maximum CADR as though they occur at one fan speed. A purifier does not supply fresh outdoor air.
Replacement-filter price snapshot: $69.99. This is not an annual ownership cost. Confirm the exact model, pack contents, change interval and current price before ordering.
