Amazing at keeping clean air
Product does its job keeping the air clean the auto mode is really useful and it is very quiet when set in night mode
JujuSep 10, 2026
AirDoctor comparable quality, but more affordable.
I love the Auto adjust feature, as you can really tell when it is working. I have a large AirDoctor in my living room, and this device works very similarly, just obviously designed for smaller areas. My only complaint was the LED light indicator; Turning on Night mode disables them, but then you lose the Auto mode. I was able to disable the LED lights using the Blueair app though ultimately. Would recommend!

Essential for wildfire season
This air purifier works. Now I can better tolerate outdoor wildfire smoke exposure when I can recover by sleeping in the clean air from this product. The white noise from leaving it at the second fan speed is a major bonus for me as well.

saved my life
i left the stove on and fell asleep the air filled with toxic smoke while i slept in background the blue pure detected a rise in contamination and was able to remove smoke more efficiently. the filter may need to be replaced but it didn’t enter my lungs

Blueair Blue Pure 511i HEPA silent air purifier
I bought this hen my two big granddoggies came to stay with us for over a month. Though I love them, they do shed and in the warmer months their smell can aggravate my allergies. We have this in our living/dining rooms. This is powerful, yet very quiet and does an amazing job of keeping the smell at bay. There is nothing I do not like about it. I am very happy with it and now thinking of purchasing another for my bedroom.

Quiet Purification
The product is very quiet even when running on high. We have ours in the kitchen/dining and originally got it for keeping the cat litter smell down (which works as expected), but as a bonus it removes all of the kitchen cooking smells (like fish). Easy to set up and the outer filter is easy to remove and clean.
