Customer Ratings & Reviews

Love the different settings. You can keep it quiet or ramp it up. Wife and I have allergies and this has helped a lot.

Absolutely works as described! You will see with your own eyes how much dust it collects.

Amazing filter. Quiet, automatic, and unobtrusive. Despite the annual cost for filters, this is a great product and worth it!

Love this air purifier. This is way quieter than our previous Honeywell. Leave it on constantly for a fresh smelling bedroom.

It’s my second Blueair air filter. Both of them are excellent. 121 is much larger than this one but does not have auto mode.

this unit is very quiet and it works great. if the air needs additional processing i hear the fan speed up.

Really nice unit, upgraded our old one. This is so easy to use and so quiet.

Love this! It’s so quiet you hardly can tell when it’s running. I have it set to auto and forget it’s even in the room.

Saved our vacation in a smelly old beach house. Easily a 90% improvement. 100% would have required removing rugs and furniture that don't belong to us! At first I thought maybe I was nuts spending this much on an air purifier, which I wasn't entirely convinced was even a thing. However, an upcoming visit from a relative with a severe cat allergy convinced me to give it a try.

Hello, This is the 2nd Blueair Purifier we have purchased. We use ours all the time. The one we just purchased we sent to my son who lives in OR. Last year he had to deal with some smoke in his home from the wild fires and this purifier will be a great addition to his home to help if they have that issue again. Otherwise it will be cleaning the air in their living room daily.

#1 Consumer Report rated. As always, they're on top of it. Best Buy had the item in stock and at the lowest price!

Excellent air quality and very, very quiet. The external filter is a bit fiddly to put on and take off.

Almost immediately, my wife went from coughing and having issues breathing to breathing easily. I swept dust up from our floors - a living room of maybe 400 square feet, 10 or so feet away from the filter, and almost immediately it started working harder to push more air (it was set to auto mode). That went far to say how sensitive it is to air quality. Only rated 4 stars because I have not yet looked at the filter to see how much stuff it filtered out, and I myself haven't felt a major difference.

Best purifier! After doing a lot of searching for the best purifier, this one outperformed. We already have one (older model) and recently got this for another room. I love that it is automatic and changes the fan setting depending on the air quality. The indicator also lets you know the air quality which is nice. I have allergies to dust/pets and my coughing and sneezing has stopped after buying the Blueair. Love this purifier!

Very quiet, hardly know it’s running. Seems to be effective so far.

I moved in to a new 1900 sqft home and bought two of these. One for upstairs, one for downstairs, and a 411 unit for the master bedroom. When we moved in it smelled like sawdust and paint. We left these on fullblast for the first few days while we weren't home and the air became 100x more breathable. It really works!! It filters allergens and looks good in our home too. Would highly rec. I got it on sale during black friday.

I am all about air purifiers, I suffer from pretty bad seasonal (seems like year round now) allergies, so I have an air purifier in each room. However, I've struggled to find an air purifier that would cleanse my living room/kitchen. It is about 320sq ft, but I have 18 foot cathedral ceilings. This air purifier does the trick in helping to cycle the air in my living area! This air purifier is pretty large, but very aesthetically pleasing, one of the most pleasing to look at on the market. It is sleek, modern, comes with fun fabric filters that you can change out to match your color scheme. It is very simple to use, just touch a certain amount of times to set the mode. No app, no frills, just a basic purifier. This is probably for the best, sure, smart features are nice, but add too much complexity to something as simple as an air purifier. The unit is easy to assemble and easy to change out filters. I would say you would get a year out of the HEPA filter before having to change it. You can remove the fabric filter and wash it whenever you want. I will definitely pick up more of these purifiers for my smaller rooms in the future, the quality of air I get from them is great. It removes odors, the auto mode kicks in when it detects any change in air quality, removes allergens, keeps me nice and sniffle free.

Best purchase we ever made , really helpful especially in the cold season

It has 3 different settings so its good for various occasions. It'd be amazing if it had an app to oparate it while away.

Great purifier! Nice and stylish, modern design that looks great in the room. Very quiet, too.
