Customer Ratings & Reviews

This is a good filter for the price but there are some odors it doesn’t get rid of fast even though it is a strong little guy it is good enough to get the job done. I know later on in the future when it dies I will get a real filter that is worth the big cost cause you can tell the difference when a good high priced filter cleans the air and a slightly cheaper version cleans.

I have owned this purifier for a few months and it does remove smoke from the area and it feels like fresh air. This purifier does cover a nice size room area.

Bought for my allergies in Spring. Keep near my bed for those months i suffer. Looks great works really well as far as I can tell. has helped a lot with my allergies when I'm sleeping

So far this has been well worth the money. I have noticed a huge difference in the amount of dust on the furniture in the room. It is very quiet, on the lowest speed you can't even hear it.

Super quiet, especially on the lowest setting. Very basic controls. I wish that the control dial light could be entirely turned off in the dark for nighttime use, instead of just dimmed. Otherwise, no complaints.

This is the best item we've ever purchased. Allergies were cleared up in days, daily dusting is no more. The machine is quiet, attractive and takes little space. I would give it 10 stars if I could!

The Blue Air 211+ works well in my home. It runs continuously and is not too noisy to interfere with conversations. It sits in our LR-DR area (L shaped). It is light-weight and easy to unpack and plug in.

Best air purifier on the market hands down. This has made a huge difference in my apartment. Would recommend to anyone with allergies or just looking for better air quality.

After educating myself on the best air purifiers our there, I decided to purchase the Blue Air Purifier. I have seen a difference in the amount of dust my Eufy Robot Vacumm is capturing and an overall difference of my allergies in the morning. I use this in my living space during the day and in my bedroom during the night. My partner loves to sleep with it on because of how relaxing it sounds. It’s also not heavy so you can move it with ease. The only thing I wish Blue would change in future products is to be able to have the option on having the light on. Overall a great product.

I use a Dylos particulate meter on the other side of my bedroom to verify performance at 0.5 and 1.0 micron partial sizes. The Blueair easily keeps the partial count amazingly low.

Bought this to help with pet odor and air borne allergens. I have no way of testing either other than I cannot smell the pets when walking into the room and have almost no allergy reaction since purchasing.

Works as advertised. Filters all the air in the house. Surprisingly haven't had to change the filter yet. At least the machine hasn't told me i have to change it yet.

It is big, seems to clean well, and is very quiet on first two settings.

Love everything about it but the fact that there is no timer. Especially that it has a “pre filter” to catch dust. Works great and noticed a great quality of air improvement. The fab also helps keep upstairs cooler by circulating the air around. We bought this for dust and definitely noticed less dust after a few weeks.

I always wake up in the morning with dry and irritated eyes. I ran this unit for 1 night and the problem was gone. It makes the room overall cleaner and more livable. Would highly recommend.

As a CA resident, the year has been tough. Hot temps with highly toxic air due to fires all across the western states. This has literally kept me and my family breathing. If I could buy another I would.

Researched a few similar air purifiers and decided on this one. $50 off plus $50 rebate helped with the decision. It has excellent reviews and they are well deserved. Does a great job and is by far the most quiet one I've ever owned.

We bought 2, one for kitchen- great room, one for basement office. Removes kitchen cooking odors quickly and improves basement air quality. I used to cough a lot and that has been reduced greatly.

Highest rated air purifier on Consumer Reports, and it works very well. It gets noisy on the highest level, but is very effective at removing dust and other particles from the air even at the lower levels.

Excellent, allergies are gone and no more red eyes because of allergies. My wife suffers from some enzymes that causes itching and after a couple of days of using this product, the itching is gone!
