Why choose Blue Pure 311i+ Max?

“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.”

    Another Happy Customer

    I have purchased several Blueair air cleaners, for different rooms, and have been very happy with the results. Allergies from pollen are already affecting people in Las Vegas now and the air cleaners are very effective in cleaning up the air inside my house. Thanks for a great product!

    Don't wait like I did, just get it

    I do not know why I waited so long to get this. I don't have a lot of allergies or anything but I do live in a house with a lot of pets (even though they aren't in my room). I noticed my bedroom air just felt kinda stuffy and stale. Well after only like 15 min of this thing going you can tell a difference. The air feels lighter and more pure. Love it already. Also the modern design and quietness of it makes it just blend it at home, you forget its there. Would recommend!!!

    timing was great

    Had to have plumbers break up a 4 foot section of our concrete slab to fix a pipe. The dust was bad. The filters cleaned it right up. Had both the 311 and the 511 going!

    I have purchased a total of 3 of these now! They make the air feel so much lighter, especially living in the middle of country farming fields!

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.

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.
