    Quiet and Efficient!

    I have 2 Blue Air Air Purifiers... the 311i+ MAX and the 511i MAX and they are great! You can tell the differnece in air quality when you walk into the rooms they are in. I love that I can control them from the App. Even when on Level 3 (I have them both set on Auto) they are much more quiet than the Levoit I have in my bedroom. I can see another 511i MAX in that room soon.

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.
