Rated 5 out of 5 stars
Very quiet!
I have only had the 311i+ Max for a week. I was initially concerned that at night it would be too loud. Much to my surprise it is very quiet even at higher speeds. If you are considering purchasing an air purifier, I highly recommend this one.

working great
following from a outstanding warranty program (Blue Air standing behind products even when "expired"), I received this unit which was easy to set up and seems to be working as expected, well.

Helps allergies!
I put this in my bedroom and I am amazed how much better I sleep. The night mode is perfect! I run the fan on 2 or 3 most of the day.

Best ever
I bought this product to clean the air in our home. I have pulmonary hypertension and it has been a godsend at keeping the air clean and helping breath better. From the moment you turn it on, with minutes you can tell the difference. The air just smells different, clean. We are just changing the filter for the first time and to see what it has removed is unbelievable. I would recommend this product if you want to breath fresh air.

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.
