Customer Ratings & Reviews

Great and sleek looking air purifier. I love how silent it is and how easy it is to set it up. Keep in mind it is not a smart air purifier and you can’t access the settings on the blue air app but it does the job well and looks good doing it so. We are using it in our mid size bedroom and significantly can tell the difference in air quality, especially with the pet dander.

I’ve used Blu Air purification for years. It was time to replace the old with the new and I trusted what I had before. I love the new design. It’s stylish in the home without being intrusive. It keeps the room clean and smelling fresh without any noise. You just know it’s working. You can feel and smell the difference in the quality of the air

I think this looks modern and sleek. Works quietly during the night time. It's been over a month, so far so good.

It seems the dust buildup on my entertainment center has slowed significantly and has become less noticeable after I started using this. I leave it on auto and it does it’s job.

Love this air purifier the auto mode is excellent for adjusting speed when needed

Outstanding item. I have allergy problems, but having a Blueair in the house has helped a TON. This is my third Blueair and the best one yet because of its high capacity and auto setting. I love being able to set it and forget it. It reminds me it’s working because when I cook something smoky I can hear it whirr up. Recommended!

Zeus (my dog) and I live in a 540 Sq ft loft apartment, and the windows don’t open. We lived here for 2 years, and even with a few plants I could tell the air quality wasn’t up to snuff. So I decided to by Blue… Right off the bat after an hour I could tell. Now, understand, on air purifiers I suggest whatever your room size is…double it for the allowed coverage size in air purifiers. Otherwise you will be replacing the filter more than you think.

Effective and good looking air purifier. The outside removable and washable cloth part makes it really easy to keep this clean. The automatic mode let’s use set and forget the air purifier. We liked this one so much that bought the 411+ A few months later

It really takes out the bad odor when we cook. Quite and very cool.

Excellent airflow, quite and nice addition to the home.

So far, I love my air purifier, its definately serving its purpose of cleaning the air in my home. Easy to use and not much to set up. It's very quiet.

I love how it detects smoke even at the dar corner of the room. Product has great form factor. The auto works like a charm. I bought my second one 2 days later. It also helps with pet dander. Absolutely worth the money.

Bought it to help with daughters allergies. The whole house has benefited. Less allergy attacks all around, very little dust on the furniture, and the house just smells better. Buying two more today

This is our first purchase of the Blueair - Blue Pure 211+ Auto 550 Sq. Ft. Hepa Silent Air Purifier and so far in been working really well for a little over a month. We keep it on for everyday use and it does help clean the air and minimize allergens. Let's see how it does in six months.

Great buy!! I have had my air purifier for almost a year. It has worked great so far. It really freshens the air and sucks up a lot of air pollutants. I got this during a Black Friday event and it was well worth it!

On low speed it is really quiet It adjusts automatically when there is a smell in the room

Bought this to compare to a handful of air purifiers and ended up keeping this one. I was surprised how quickly it kicked in while cooking and it's ability to filter smaller particles. Having family members that are basically allergic to everything and saying they don't have any reactions while at my house makes me feel like I made the right decision!

The Blueair Pure 211+ Auto has impressed me both in styling and performance. In its first 48 hours of use, I've seen and felt the impact it has made to the air I breathe. With the pandemic still lingering, I've had a lot of time to transform my 500 square foot garage into another inhabitable spot in our home. A man cave, if you will. Here is where I perform my work-from-home duties, watch TV and play video games. The trouble with the garage is it's not quite as insulated nor sealed as the rest of the home, so particulate matter and dust roams freely. I notice daily because my keyboard is covered in it by the time I begin my day. The 211+ Auto changed that overnight! On the first night, I ran it full blast to get the air in a nominal state before switching to auto. Within a half hour I can already smell the difference; the air was removed of garage smells and it was very pleasant to inhale the fresh air. I couldn't believe it. Waking up to see that the keyboard had much less dust on it was a happy sight to see. The next day I decided to take it up a notch for the sake of experimentation. With the garage door closed, I took my leaf blower and proceeded to cloud the garage air with many months old dust and dirt that has settled on cabinets, crevices and everything in between. It was terrible! Immediately, the 211+ Auto signaled that the air was full of pollutants with the red light. About 20 minutes later, it had changed to amber to signal an improvement in air quality and shortly after, nominal blue. It took about 30 minutes total to change from dust storm to clear. The dust haze was gone and the air was fresh again. That's fantastic. This thing has been engineered to clean your air effectively, yet move huge amounts of air. The dust that ended up settling back on the floor and other places...well...that’s on me to clean up. Using the 211+ Auto is very simple with a single button up top with 3 lights to form a circle. Each light represents low, medium and high speed settings, and all lit means automatic speed setting using the particle detector for speed metering. I plan to use it in auto as it is the best combination of clean air maintenance and quiet operation. Medium and high settings can definitely be heard, but it's not terrible, in my opinion. A small LED in front of the unit informs you of air quality status and only illuminates in amber or red in the presence of higher levels of particulate matter. Aesthetics-wise, the Blueair Pure 211+ Auto can complement any room (or garage) by changing the pre-filter to color-match its surroundings. In my garage, I have blue and gray nitro floor tiles and the gray pre filter that comes with my 211+ Auto matches it perfectly. The pre-filter is machine washable as well. Maintenance is case by case, but for most it will be every 6 months to replace the internal filter. For my garage, I’ll probably have to replace the filter 3 times a year, but for me it is totally worth the cost. The Blueair app cannot be used in conjunction with the 211+ Auto, but you can get outdoor air quality information about your specific location (PM2.5, PM10, CO and SO2). It would have been a nice touch to add this capability to this unit since they do have other units that support wifi connectivity. You can also manage your filter replacement subscriptions in the app as well, but honestly the app doesn’t add a whole lot of value if I cannot monitor/control my air purifier remotely. This is really not a deal breaker at all as it automatically adjusts itself to the air quality so I don't have to know its status and make the adjustments manually. Just turn it on to auto and make sure to keep the power running at home. As I continue to run it daily, I often seen quick moments of the light indicator switching to amber and back to blue. It's really a comforting sight to see that it was recognizing the air quality and making automatic speed adjustments to clean the air. And it looks good too.

My house smells cleaner and also I haven’t had a headache since I purchased this

I have been using Blueair purifiers for about 7 years. My 403 got so old but still worls great. We added the 211 and 411 Auto. They both work fantastic. I would recommend for the hepa silent tech they use. Its not true Hepa its better at 99.99 percent filter rate. Their filters allow air at high rates or CADR higjer than the competitors.
