“I love that I can operate it from anywhere with the app. I can get it going before I get home from being outdoors. It is a very quiet machine. It has night mode and will dim or turn off all lights on the machine.”
Lesann
“I like having a one for each high-traffic room such as our master bedroom, office, and living room. Although this one was intended for our office, it is by far the most attractive air purifier I have yet to see, so I swapped it for the one we had in our living room.”
MrsAdams
“The unit will automatically adjust according to the air quality, and there is a light indicator letting you know how it accesses the value. You can also set it manually, with three fan speeds, and wireless capabilities.”

The Blue Air 511i Max Bundle purifiers are excellent. They clean the air and are very quiet. The controls are easy to use. They provide great environment for my asthmatic symptoms.

I’ve been dealing with LA fires and it’s crazy how quickly this little monster clears the air. I like how it tells me what the air quality is and when it gets better with a little light indicator. It’s also super quiet but very efficient. And it looks nice too. I wish I had gotten one soon. Had a Levoit brand, but it wasn’t nearly as good.

My first 511i Max failed for no reason. It just stopped working.
Blueair replaced it immdiately...no questions asked. The sent a new unit and a mail lable to use to pack the failed unit into the incoming unit box and return it. It was as easy as a return from Amazon, which I consider the Gold Standard for product returns.
GREAT job, Blueair team.
