    • Small Size, but Big Performance.
Style: Small Room - Wifi
I read a ton of reviews, this one seemed to be Solid. App was easy to install and set up. Provides air quality statistics and other information. Provides plenty of options. Very quiet on the lower settings. The # 3 is louder that the rest, but never obnoxious. The air in the room is noticeably cleaner. Before I started using this, the dust would build up on all the surfaces. Should be a huge help when allergy season hits in the spring. Now there is hardly any dust at all. This is a very nice looking unit. Small size works well in small rooms and even on counter tops, etc. Well worth the price, would buy again. ... show more

The media could not be loaded. So far, this air purifier has been excellent. The app is very detailed and easy to use, and I like how it explains the readings and what each level means. The technology is great, and the system actually adjusts on its own when windows are open, while cleaning, or when cooking. I do prefer the smart display on the larger unit, but this definitely gets the job done for bedrooms. It runs much quieter than it sounds in up-close videos, even on higher fan speeds. The air feels noticeably cleaner. We have noticed a difference in stuffiness and allergies. We have one large unit for the main floor and two medium ones for bedrooms. I plan to buy at least one more large and three more medium units because they work that well. Great value for the price and quality. I run these all the time at the moment, but love the option to schedule. The size is perfect for a bedroom. ... show more

    • Breathe Easy with BLUEAIR Air Purifier
Style: Large Room
I have pet and seasonal allergies and this air purifier helps keep my airways clear. Most effective unit I've ever purchased. Since adding one to my bedroom, I'm not needing to use my inhaler at night and sleep much better. This unit is especially quiet and not distracting. The washable outer filter is easy to switch out, and the unit wipes clean. We have three units placed throughout the house and they've kept running for 5 years so far, with regular filter changes. Very impressive! ... show more

    • Alexa does not work with this !!
Style: Small Room - Wifi
Good Product. Alexa Integration does not work. Amazon says that the Blueair skill is no longer supported. This is a disappointment and honestly false advertising as it clearly states that it is Aleza compatible. Does what it supposed to do - clean air very well.

    • Five years of nonstop operation and it still works like new!
Style: Large Room
This review is for the two 211+ (not automatic) units I've had since 2020. Initially, I purchased these after the devastating wildfires in the Pacific Northwest when people were sealing off their windows with tape and using box fans with furnace filters on the back in a desperate attempt to remove the wildfire smoke that had infiltrated all our homes. And with three not-small dogs anyway, it just made sense. Five years in now, I can say that I have been EXTREMELY satisfied and impressed with both of my BlueAir 211+ air purifiers. The initial setup and subsequent maintenance is effortless. You take it out of the box, put it's little prefilter on the base, drop in the air filter, pop the top of the unit containing the fan back on, and forget about it for a while. I replace the filters about every 6-9 months, and wash the prefilter cover way less often than I should considering the amount of dust it very efficiently sucks up. With one in the living room and one in the main bedroom, I have both ends of my home more than covered, as with the two combined, they are rated to filter more square feet of air than the size of my house. I've literally had them both running *nonstop* for the ENTIRE five years I've had them, and haven't had a single problem with either of them. Once in a while I'll come home to find that during rambunctious play or a particularly assertive barkfest at a delivery person, a dog butt has grazed the power button on the one in my living room enough times to turn the unit off. Kept on low, the fan is incredibly quiet and barely perceptible if at all. The only reason I notice it's been turned off immediately when I come home because the living room smells noticeably different when the purifier hasn't been running; the air smells comparatively stale and decisively more like dog than when it's running. I also noticed and appreciated their impressive performance in 2022 when once again, my city was infiltrated by wildfire smoke from fires that were literally hundreds of miles away. The air quality outside was dangerously high, but inside my home, per my thermostat app, the air quality was normal. This was particularly impressive considering it was literally snowing ash outside, harkening back to the much closer terrifying fires of 2020 that nearly breached city limits. Having these in my home gives me piece of mind that I'm about as protected as I can be against airborne pollutants like smoke, dust, pet dander, and the occasional cooking-adventure-gone-awry. Eventually when these do stop "biting the dust" as it were, I'll gladly replace them with the newer model that has the power button on top and the ability to turn off the power indicator light, which I desperately wish my older model had for my bedroom unit. ... show more

    • Powerful quiet and truly automatic
Style: Medium Room
Review Image by Kelly B Kelly B
The media could not be loaded. This air purifier has completely exceeded my expectations. It is extremely quiet on every setting and you can see in my video how smoothly it runs. The auto mode is the best feature by far. It is so sensitive that it will kick on from across the house if I spray hairspray in my bathroom about twenty feet away. I love knowing it is constantly monitoring the air and adjusting on its own. The design looks clean and modern, it covers a large space easily, and the setup took just a minute. I have noticed that the air feels fresher and the room does not get stuffy at all anymore. It works so well that I am planning to buy another one. ... show more

So the unit itself is very good, this is my second purchase. The air feels crisp and clean even with 2 dogs and lots of plants! Noise level, for me works like a white noise, it does have a barely noticeable night mode. Oddly enough I actually had to return and reorder both units due to damage while shipping! Not sure what is happening there so maybe order two lol ... show more

    • Quiet and efficient air purifiers powered by two different types of filters
Style: Large Room
I have four of these high quality BLUEAIR 211+ large room air purifiers, two upstairs and two downstairs placed on both sides of each floor. I run them 24/7 on the lowest of three settings and they are very efficient in removing dust and other allergens. They come with two filters: one is a reusable cloth filter that I wash inside a mesh laundry bag every three months. The other is a disposable correguated paper and plastic filter that I replace annually. At the lowest setting, the BLUEAIR 211+ emits a barely perceptible hum. While they may be larger in size compared to other air purifiers, I have not found that to be an issue and I have been able to fit my four 211+ units comfortably into each room where they function well to keep the air clean. ... show more
