Seems to work well, really reduces odors and allergens
This is a review of the 211+ (not auto) product.I purchased this to take the place of a Winix 5500-2 that I moved to a smaller room. I did a fair amount of research before deciding on this model. I wanted something under $300 that could filter a larger room. Consumer reports and the Wirecutter both rating this model very highly (in the case of CR this model was only beat out by the Blueair Classic 6XX model and that one goes for nearly $800 right now and is only somewhat more powerful.The unit is very simple. It’s a large fan in an attractive white housing with a slightly larger white plastic base that houses the main filters inside. There are two different colors of the washable external cloth filter in the box. You can use whichever one you prefer. My unit had a reasonably bright blue one and a dark gray one. It’s nice that they give you 2 of them. They only give you one of the large internal filters.The power cord is attached to the back of the unit, so if you break it or a pet chews the cord, the whole unit will have to be replaced. That’s a shame.The unit itself is made mostly of plastic, which makes it light and easy to move, but it won’t stand up to abuse. If your kid sits on this, it will break.I find the size to be good. It’s not really enormous, as some large room purifiers are, but it will take up more floor space than the Winix 5500-2 (but it isn’t as tall).The unit pulls air from all 4 sides, so you can’t stick this right up against a wall if you want the best performance. The clean air comes out the top of the unit.As for the sound at full power, a noise meter registers 64 dB right at the top of the unit wheee the air comes out. To put this into perspective, my Winix 5500-2 registers 74 dB at the air release when it is also on full power. The Blueair’s sound is noticeable, but it is very even and is decent white noise at top speed. I haven’t had a problem falling asleep near it. The Winix can be annoying at full speed.At the lowest speed for both the Blueair and Winix, they register at 42 dB measured from the same spot as before. You’ll have a hard time hearing them at this level unless the room is really quiet.The Blueair really moves air well. At top speed, you can feel the air moving in all parts of the room. It will make the room feel a bit cooler. It is noticeably better than the Winix 5500-2 in this regard.Controls: there’s one button. You tap (not press) it to control fan speed or turn the unit off. The top rim of the button lights up with a pretty bright white light to let you know the fan speed.The one thing I miss with the Blueair 211+ is there is no automatic mode. The Winix 5500-2 offers this and kicks the unit into higher gear if air quality is poor. It’s not a deal breaker, but I do appreciate the feature so you can save money but still have very clean air. There is a newer version of this Blueair that does offer automatic mode with air quality sensing. If you want that go with the 211+ Auto model. The price difference wasn’t worth upgrading, but you might catch it on sale.The Blueair does not have a remote control like the Winix 5500-2, and that I definitely miss, especially without the automatic mode.The cost of replacement filters seems about the same as other popular air filters and they offer a wide variety of colors for the external filter.A word about putting on that external filter. It goes on like a sock, but in order to stay in place, you have to put the filter material over the top part of the bottom white plastic unit. This means the filter will cover the latching locations where the top part locks into the lower part. I find this makes the security of the latching not as good, but it works well enough to keep the two parts together.The Blueair is not very heavy and I find it easy to move (though you may want to move the two halves separately if you find it awkward).As for air quality, Consumer Reports seems to be correct. It has done wonders for reducing allergens and smells. It also does this without the trendy but potentially problematic negative ion generation that some other filters offer. I find this to be a pro for the Blueair. I don’t need more ozone in the room.I did not have any odd smells from this unit, even with my nose up close. Based on other reviews I may have gotten lucky or perhaps they’ve improved the production process.All-in-all, I find this a great unit for the price.

Very quiet very impressive
The media could not be loaded. I bought it less than a week ago i already love it. There are 4 fan speeds. Its silent at night mode, at fan speed one its almost silent hard to noice it sometimes at 2 its noticable but still quiet, 3 is lound but not very loud. I bought it to remove vape it it removes vape smoke at level 2 and 3 very well. It seems to help with nasal congestion and smell removal. The app is excellent. Auto mode is very good i leave it at auto whenever i vape it detects it and ramps up removing the smoke quickly. The only thing i don't like about it is the look. It also helps with dust collection, my room is very clean after using it but i dont like this fat bulky design its fatter in the bottom. I prefer sleek shrap designs

Awesome air purifier.
Awesome air purifirer, purifies the air quality quickly depending on room size. Bluetooth connection is easy and has a timer function, the app is easy to work and tell you when it's time to change the hepa filter. Works great.

Third time’s a charm?
Update: it appears that persistence with the phone number is the best way to get a response from this company. I got no reply via email but finally got a live person on the phone. They were pleasant and I will be exchanging the unit for another one. Hopefully this one will last. I’ve changed my star rating back to 4.I don’t know what the odor problem is that people keep mentioning. So far I have had no issue with odors from the device. My problem was the button keeps malfunctioning.Update: This is my second unit that I got when the first one stopped working in less than 6 months. This one too is stuck on the low setting and the indicator light is red. I can’t reset it. I can’t change the speed. The button just doesn’t work anymore. Tried calling but could not get anyone to answer the service line. Tried to click on the online chat but that didn’t work. Sent an email request and it’s been almost a week with no reply. For the price of these things they should last longer than a few months. Mine is mostly on one setting and I turn it off weekly to vacuum the outside filter so there’s no reason it should be broken. Again. I’m completely disappointed with this and have changed my original review from 4 stars to one. Like many other people on here I would like my money back.I bought this for a bird room. It does what it should. I wanted a filter that had a pre filter I could vacuum off easily and this had that. I could easily see how much dust was on it. Very quiet on low. It’s a bit noisier on the medium and high settings. Unfortunately, the unit stopped working properly after two months. It was stuck on the low setting. I could not get it to turn off or do anything other than run on low. I contacted Blueair customer service and got a live person who was extremely helpful and since it was under warranty they replaced the unit. I’d like to give a five star review and if the first unit hadn’t broken I would have but since I can’t be sure of whether this one will last or not I’m giving it 4 stars.
