Cleans and deodorizes air
My 511 is a blessing! I have two small room units and both do quite well in. Euyralizing odors of all kinds in the two rooms they occupy.

Fresh air
The air in my home is much improved and much less dust. My nose hasn’t been running like it did before I got this air filter. I’m very happy.

Feeling better
Sneezing has stopped and so has my constant runny nose. My red itchy eye has lessened.

Outstanding air quality
My granddaughter couldn't come to my house without having sneezing fits. After BlueAir she spends the night and has no issues. It's so worth it.

No more cat box smell.
We bought this to try to help with the smell of the catbox. It sits on top of the crate that it’s in. I still clean it every day but now nothing nasty hangs around. It’s like we don’t even have a cat. We’re very happy.

Blueair 511i Max Purifier
This air purifier works well. It has very easy setup and is extremely quiet. I have used it exclusively on the Auto setting, so it increases air purification as needed; otherwise it runs on very low fan speed, which conserves energy. It is very nice that it can be controlled via WiFi connection to the app. The app affords even more settings to control the air purifier than just the buttons on the unit, which I find useful. This air purifier is definitely a quality device.

Right size for the bedroom
It’s quiet, especially on night setting. I like that lights can be dimmed. Works well.

Better than expected
We didn't expect our filters to get as dirty as they did in 6 months, but have decided now we will be checking them in 3 months to decide how often we need to replace the filters.
