    Very quiet!

    When we first plugged in and got the purifier setup, all the PM ratings were 0. I was thinking something was wrong. It was like that for several weeks…until our area was affected by the northern MN/Canadian fires. Then in jumped up! I keep the fan on auto most of the time, but I did bump it up to 3 so that it could clear out the air faster. When on auto, I can hear when the fan kicks on at a little higher speed, but it didn’t go as high as 3 or 4, so I manually did that. It would be nice when the purifier detects a PM number above the “excellent” level, that auto kicks on high to get the air back down to excellent level quicker. Overall, I’m happy with the purchase. I wish I had 2 - one for master bed and one for living area. Right now, I just move it to LR during the evening and to Master bed at night time. It’s light enough for me (51 y/o female) to easily carry around to the different rooms.

    I love this air purifier

    That’s a great air purifier. I had the larger model for years and absolutely loved it, but I’m very pleased with the small, quiet Compact 511. I highly recommend it.

    I’ve also owned a Shark air purifier, and I wouldn’t buy one again. In my experience, the quality of the Compact 511 is far better.

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.
