“I recommend Blueair air purifiers to my patients because of their strong performance and their commitment to third party testing, which gives me peace of mind that the airborne particles that commonly exacerbate allergy and asthma symptoms are being captured*”

Dr. Priya Bansal

“Blueair's 311i+ Max was the best at capturing the full range of contaminants floating through the air in a typical home. Its advanced multi-level filtration captures contaminants of all sizes — not just dander and pet hair, but also cooking fumes, dust mites and pollen.”

Blue Pure 311i+ Max
Purchased the Blue Pure 311i+ Max unit for a space that totals 545 square feet. The unit is doing everything the manufacturer says it will do. I keep it on auto and the machine adjusts itself when it detects pollution. I used hairspray near the unit once and it increased the fan speed to clean the air. It returned to auto when the space was clean. I run the fan on 2 for about an hour if I find allergies are bad. We have had two different name brand air purifiers in 6 years, this one is superior.

I bought two of these, and they have been a tremendous help with my allergies by keeping the air in my house clean and crisp. I love the automatic and sleep settings. This is in a league of its own compared to the previous device I owned. This worthy investment

Fantastic air purifier
As someone with severe allergies and asthma my Blueair 211i max has been such a blessing. I’ve only owned the unit for two weeks but can already feel a significant improvement in my symptoms. I highly recommend this unit.

¹ Tested on PM 2.5 up to 90 mins

² Based on ELISA deactivation testing of Pollen (Cry J1), Pet Dander (Fel d1, Can F1), Dust Mite Matter (Der f1) on the filter media in 60 minutes.

³ Compared to standard in-unit filter. Based on removal testing of particles 0.4-0.7 μm in 60min in a 30m3 room. Performance may vary.

⁴ When similar CADR was measured, Blueair models with mechanical and electrostatic filtration achieved less noise with less energy than same models with only H13 HEPA mechanical filtration.

⁵ AllergenBlock refers to inanimate allergens pollen, dust and pet dander.

* Comparing CADR performance of Blueair models with mechanical and electrostatic filtration vs same models with only H13 HEPA mechanical filtration.
