    Well designed air purifiers!

    We have now purchased three Blueair 511i Max air purifiers - one for each floor. I really like the size and the look of the units. We run them on the middle fan speed setting and you barely notice the sound. On the high setting, you can definitely hear them running. The removable, washable cover is a great idea. So far, my sense is that most of the dust gets caught in the outside cover so the main filter should last quite a while. It’s pretty easy to remove the outside cover and shake it out or blow it out using compressed air. These air purifiers are well designed.

    Excellent

    I really like how quiet this is despite its size. It cleared the smoke from my wood stove quickly and automatically went back to automatic setting.

    Wonderful!!

    The minute I turned it on, I could start to smell and feel a difference in the air in my home. I live in an old building, there’s lots of mold. Within an hour, my living room felt much easier to breathe in. It’s incredibly quiet, I’m looking forward to buying one for my bedroom!

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.
