  • A Sophisticated (and QUIET) Air Filter
I am reviewing the BlueAir 211i Max and 411i Max series in this review as I bought both - one for living room and one for bedroom. Bottom line, these are very impressive units and for the price I am impressed and pleased with each for functionality and effectiveness. Pros for the BlueAir series. very very quiet. On auto maintenance mode - you can't hear the thing. These are smart machines. You can monitor every aspect of your air quality through the app. You can adjust the control lights from off to bright. It tracks months of air quality data for the room it is in by month, week, day. You can adjust from sleep mode, auto, and 3 fan speeds using the app remotely. It tells you how much filter life is left. It tells you the outside air quality and compares to your inside. Example of its effectiveness; I was sautéing some Italian sausage and onions, the unit detected the particles and immediately went into high mode for about 5 minutes until all the odor was eliminated and then went back to silent. The front LED bar changes from Blue to Green, orange and red depending on the air quality while at the same time adjusting the fan speed to address the corresponding level of air quality indicated. Same thing happened when smoking some meat on the back patio. I left the door open to bring in the food, the unit detected the smoke and the front LED went red. After closing the door, it ran on high mode until the LED indicators began to regress back to blue and the fan speed decreasing accordingly until all the smoke odor was eliminated from the room. Cons for the BlueAir product. It is a bit pricier than other options - but for all the differences - so far, I feel the Blue Air product is definitely worth the price difference, for me at least. What I have not addressed: the longivity of the products; the life of the filter; ease of maintaining; Both of my purchases are within the first month; ... show more

  • 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

  • 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

  • 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.

  • Powerful quiet and truly automatic
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
