Customer Ratings & Reviews

I don’t really notice a difference since we got it. I keep it running in my son’s room since he has allergies, but it doesn’t change color like it’s sucking up any dust until we sweep.

This is a tiny unit. This is a quiet unit. It doesn't have many bells or whistles, but it's great at doing its job. My wife is particularly sensitive to the air and she immediately noticed the improvement in quality. There's not much to operating the unit. I do like the automatic mode and the LED that provides overall air quality. Again, it's a pretty quiet unit (with full power mode being louder but still not that bad.) Finally, and this is probably more a subjective thing, the design of the unit is unobtrusive and blends in well with the room. Being a relatively small device means it doesn't really stick out - and that's a good thing.

Havent Noticed a difference at all. Ive struggled with asthma and sinus congestion my whole life and this has brought zero relief. Have used for over a month and my headaches are worse than ever

I bought it, got home, opened the box, it was broken... I exchange it, after a while it broke down. Horrible, cheap product. Waste of money!

Ive had the pleasure of using this air purifier in my bedroom for the last two weeks, and it's been pretty awesome. Here in central Texas we have mountain cedar season, and every year it messes me up bad. I haven't had my usual severe allergy reactions this year and I'm convinced that this air purifier might be the reason. I also noticed that my bedroom doesn't get as dusty as before. It was very easy to set up, I just screwed the top fan into the filter and voila. good to go. The purifier has several different settings, but I leave it on auto mode. It will kick on at higher speeds if it senses that your air quality is poorer. Even at its highest setting, it isn't very loud or bothersome. I haven't had to change the filter yet, but I know it will be easy to change. Its a quick easy twist, and remove the washable pre filter cloth cover. Filters are very affordable as is this purifier. I highly recommend it, especially if you suffer from allergies. This has helped me a lot. I breathe easier and my bedroom is noticeably less dusty. Pros: Easy filter changes Very quiet Auto Mode that detects air quality Cons : None

Seems to work, not sure how well it does everything is claims.

Was filled with spiders when I turned it on did not like at all too scary

The unit was great while it worked. Right after 1-year point, I had problems with it. I tried contacting Blueair by phone and email and couldn't get any help.

I will start by saying I am literally allergic to just about everything environmentally, trees, grass, my own dogs, everything. I was able to use this before my recent round of testing when I wasn't able to take any antihistamines and this was used in my bedroom. Needless to say, this little whisper-quiet machine helped me through and was able to give me some relief rather quickly. The unit itself is easy to set up and the fact that the internal filter lasts 6 months, is better than any other machine I have had previously. It is discreet, barely audible (even on the highest setting it is still quieter than any other machine I have had before), and easily blends in with the decor. Definitely a really great investment for anyone suffering with allergies.

We wanted a HEPA air purifier for a student isolation room for return to school during COVID. The room is relatively small, around 100 SqFt. but due to the risks associated with children and adults going in and out of the room throughout the day, we wanted something that could turn the air over sufficiently and not take up much space. This did the trick. It was easy to set up in the room and the one button design made it easy for people to adjust up and down the circulation with little surface touching. Since the button is very slick, we're confident a simple wipe will eliminate worry about surface transmission.

I am uncertain exactly how to explain my lack of satisfaction; has not worked; cannot make it work. The good air signal has not changed EVEN when it is obvious the air quality is NOT good. I’ve done EVERYTHING I can think to change it’s uselessness.

I have used this for months and I cannot tell you the difference between when it is on and when it is off. I honestly have no idea what this product is supposed to do.

We are using this air purifier in the bedroom. I feel less nasal congestion since the first night we plugged it in. The machine is so quiet. I have noticed no dust particles floating in the air when the sun shines in the windows. This is a great machine. I need more of these.

It simply stopped working. I had it for about two weeks or so. I will not buy it again.

Operates well but, doesn't last long, you have to rebuy or exchange for another Air Purifier that is a different brand.

Overall I am very impressed and pleased with the Bluair blue pure 411. I have had a few air purifiers during this pandemic and this has been by far the easiest to use. Once you unbox it and plug it in all you need to do is press the power button and the blueair will adjust to your room and start purifying. Its a very elegant and aesthetically pleasing product and happens to match the room it is in perfectly. Since receiving this product I have recommended it to a few others who have purchased it and enjoy it as well. I really recommend it. It also is HEPA approved product which is key.

Stop working after a week. Don't recommend this product.

My first air purifier. I read various reviews and decided on this one. Seemed sold out everywhere including the BB I got it at. But they had it. On the lowest setting it is silent. Second setting is very quiet, if 10 feet away, you can’t hear it. Full speed I use while away. I haven’t seen it single bad air, but seems to keep my little space space smelling clean.

Works like a dream. I haven't been having nose issues this past two weeks. Usually my nose feels pretty stopped up due to the stuff in the air in my home office. I have not had a stuffy or nose itching issues. The air definitely feels cleaner and my nose is proof that it is working. Absolutely love this cleaner. I have it on auto so basically set it and forget it.

The filter is a huge upgrade from my previous one, I can tell a difference with my allergies do not bother me as much as they were before. The filter is being used in a small bedroom / office, the smells that would linger from my lunch are not hanging around as long as they were before. The filter came in simple packaging that was recyclable and was pretty much a plug and use device, there were no components that needed to be put together. There are options to turn off on or auto. I did not want to bother with remembering when to turn it off or on so I set the filter to auto, The filter is not quiet to me but it is also not loud. It is definitely noticeable to me when it is on but it has a white noise effect to me and kind of fades to the background if there are other noises in the room. If the room is quiet you will hear it but I have sort of tuned it out. The filter is compact but not small, I have it sitting on the floor in the corner of the room. It can fit on a shelf or desk but the profile of the filter is not slim and kind of stands out and is noticeable. I wish that it would blend in a little bit more, maybe more furniture like? The filter has both a pre filter that is bright and colorful and a standard filter inside. The prefilter is designed so that its the first layer of filter and should catch most of nastiness and allow the other filter to do less work. I am curious to see how long the filters will last, it looks like it should be easy to change. The pre filters have different color options to switch things up. The main filter is a bit more but heh. The indicator light on the fiter will let you know when it needs to be changed out. I don't know but it is definitely a buy and works so I would suggest if you have allergy problems to give it a try, it's the best one that I have used.
