Frequently Asked Questions
Which is better for a large living room?
The Blueair Blue Pure 211+ is better for large living rooms due to its 540 sq ft coverage and 350 CFM CADR. If your living room is under 350 sq ft, either purifier works well.
Is Blueair HEPASilent better than True HEPA?
Blueair's HEPASilent uses a different approach combining electrostatic charging with mechanical filtration, which can capture smaller particles at a higher rate. Both effectively clean air. HEPASilent is proprietary and has less standardized testing than True HEPA.
