“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

“It has a night mode, which turns off all of the onboard lights and quiets the fan even more, making it the perfect option for a room where you primarily sleep and relax.”

Best For Bedrooms

“It has a quiet operation which, along with the dimmable display, makes this a great option for the bedroom—or you can set it up right by the litter box or dog crate to absorb odors.”

Kitty Litter Lifesaver
These air purifiers have been one of the best investments since I got my kitten. I love him, but he has some big bathroom odors and I don’t love that. I put a unit upstairs and one downstairs next to the bathroom where his litter box is and it has been a game changer.

Quiet and Stylish
Did some research and liked the look of the 311i Max. Wanted one with a cleanable filter as well as a HEPA. Packaging was well done, setup easy and the app works well. Super quiet machine.

Love Blueair products
Quiet but high powered. Immediately felt a difference in air quality. Wish it came with a second pre filter like my other blue air purifier.

False Advertising
The product is great but the packaging and website has false advertising. This model does NOT have sensors to monitor PM10 or tVOCs in the app, which I was expecting when I purchased.

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.

⁵AllergenBlock 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.

Note: CADR and room size values have been updated to meet new DOE standards. Website listings reflect the most accurate information. You may notice slight differences versus product packaging during the transition.
