Customer Ratings & Reviews

Yes there is a plastic seal which you will see when pulling the purifier out of the box. I upgraded from the 211+ Auto which I ran on high 24/7. There was definitely a storage smell that had been built up on the 211i Max so I ran at full speed for 72+ hours and that smell was gone. That’s the only thing with this one. Pros: Upgrade from 350 CADR to 401 Smart Display which shows EVERY PARTICLE SCANNED into the filter which is also included on the Smart BlueAir APP (iPhone) So you can see exactly how clean the air is. I have mine automated to turn to auto when I leave the apartment and then when I am about 2 miles away from the apartment, the purifier goes full blast for about 15 minutes so by the time I get home, the air is fresh. This is a crazy advantage filter wise which they are now boasting 9-12 months. The 211+ Auto I swapped out religiously every 6 months. The sensor on this air purifier is the true intelligence behind this Swedish engineering. I vape in my room which is a dorm (so maybe 150 sq feet). When I vape medical marijuana and have the device on auto, it is picked up immediately. The part per million jump to over 300, and in about 30-60 seconds, the display shows ZERO PPM and your air has effectively been cleansed. No Smell or Mary J. It’s like it never happened. Even if I cap from across the room, it kicked in and auto tunes to the proper cleanse to get that number back down to 0 PPM. The Auto Feature on the 211+ Auto wasn’t bad in my opinion. I thought it was good. After owning the 211i Max, its like a halo. There is 4 fan speeds and an auto and night. Power on Power Off and wi-if signal, to show it is connected. Your remote Control, is your phone which in my case is an Apple iPhone 14 pro. The highest gear (level 4) is where I keep it, which is one decibel lower then level three on my old 211+ Auto. The 4th gear is noticeabley different suction pulling in more air at a ever so slightly quieter decibel level that the 211+Auto. Part of me wants to smoke a cigarettes in my room just to see how well it does and how fast it goes to 0 PPM, but I quit smoking cigs a long time ago and the last thing I need to know is that I can smoke cigs in my room. Marijuana Vapor, when placed on Auto before the session, eliminated the odor in about 1-5 minutes. Once it kicks in I set the setting on high. Overall, I do not know how they beat this one. Wish it came with an extra pre-filter but whatever. Price of the replacement filter is the same price as the replacement on the 211+ and 211+Auto. A lot of people will probably be turned off by the initial smell. 72+ hours of full speed and you now have the new number one rated air purifier of 2023 (guaranteed), the 211i Max being #1 next to the 211+ Auto, which is 2nd. Before returning my 211+ Auto I placed both purifiers at opposite sides. When blowing vapor in the middle, the 211+Auto was left powerless to the suction of the 211+ max. It might be nice to have this one turned on at all times and another on auto. For me its the Dyson HP01 (COOL-HEAT). I just keep it on oscillating and auto. Jet stream no intake on the Dyson. I use the Dyson at night for Direct Clean air on my face at a preferred speed. Or in the winter, I will set the temp to 70 degrees and still keep it on auto. The 211i Max spreading the heat within seconds and then the Dyson stops as it reached the temperature set. I think this Air-Purifier will make both my Dyson filter and the 211i Max filter lasting longer as the 211i Max has the smart features and the Dyson is left on auto and never turns on. Which is why I use it at night to oscillate or agitate the already clean air pushing it all back into my room. Best air purifier for the Money CADR and Smart Features hands down.

Blueair air purifiers are sleek, quiet, and excellent at cleaning the air—especially in medium to large rooms. Their HEPASilent™ technology combines strong filtration with low noise, making them great for bedrooms or living spaces. However, the filters can be pricey, and some users notice a slight smell when first installing new ones. Overall, they’re a solid choice if you value design and performance and don’t mind the higher cost.

quiet and cleans the air great. when you cook it goes on and takes away the smell of food also. easy to clean the filter and easy if you have to replace the filter. Takes the odor out of the air

I love this product. I remember searching for recommendations for air filters since my house was built in 1984! I wanted to have as much clean air as possible. This filter works perfectly, the air feels cleaner and less heavy, and it's not loud at all I have it in my bedroom or sometimes in the living room. It connects with the app and you can switch the type of filtration needed, for example, if you are cooking much one day you can select the boost mode, I usually have it in automatic. I do not reject buying it, it works great, and I love it. If you need an air filter this one won't disappoint.

No Sound detected from Blueair. Great for Big Room, quiet and does its work that I needed it too. Customer Service was excellent, my compliments to Peter Abbott and his supervisor Victor for helping me with my purchase and recommending Insurance for 2 years.

We had several air purifiers from a major brand. They were decent but pretty basic. No onboard intelligence or real knowledge about the air in the house. So we bought the smaller room-size 511i Max for the bedroom as a test. WOW. Immediately noticed the room smelled like nothing…a good thing…and we slept better. After a month, we bought the big 211i and let it go to town. Again…WOW. It is in our main hallway, under a HVAC return. The whole house is better. The app is pretty good. I was surprised, actually. There are videos for changing the filters. Easy to use. Noise on Auto is nearly silent, even standing next to them. When we had something smoke a little on the grilltop one night, we heard both cycle up to HIGH and they were audible but not LOUD or annoying. And, they cycled back to Auto when the air was clean…about 20 minutes. Now, the filters are not cheap. BUT, you know…from the app…where your filter is at, so you know when to replace. 511i is at 10 weeks use and still has 77% filter life. There are 3rd party filters for about 1/2 of what Blueair charges. They also have a 15% discount if you subscribe to a replacement plan. We will probably try the 3rd party option first. Overall, our allergies and wife’s asthma are just not a problem now. Very pleased.

Very happy with this air purifier. Super quiet and definitely gets the job done. Easy set up and user friendly. I like that you can simply wash the outside fabric filter which catches larger particles and helps save on the replacement filter. I purchased 2 - this one for living room and a smaller for bedroom. Very happy with both.

This air purifier is great. It works quickly and quietly enough that we can sleep with it running. We purchased it to help with cat dander and within minutes of starting it the air in our bedroom was noticeably improved.

Me and spouse were looking for a new purifier for our bedroom since we moved our 211+ auto (previous generation) to our living room. Bought this new generation purifier and it’s absolutely amazing! I must say it did get rid of all the allergies from the pollen that was discovered in my room. One thing I noticed is, when you open this out of the box for the first time be sure to put the purifier on max so it can air out completely for at least 30 minutes to an hour. It does have a new type of smell but after the timeframe it should go away. I think this smell happens after setting in the warehouse for a while.

Great air purifer! Very well designed, extremly quiet and worked great during the spring pollen season.

Bought the filter when the wildfires were having our air quality so pour I was getting really sick. The filter is easy to set up, the app is fairly easy to use. The app can be a little glitchy if you use multiple phones to talk to it. Sometimes the air quality readings can be glitchy. Aside from these small issues though, the filter does an amazing job. Also, at 4am when the neighbors dog starts barking and waking me up, I turn the air filter up and the white noise drowns it out. It's quiet on low but turned up it gets loud. Not annoying though, just loud.

For people with pets. This is hands down the best filter that i have used. I love the wifi control. I have 3 of them throughout the house. One inside where the air intake for the house is. These capture dust and hair on the outside protector. So easy to vacuum off. Prefer over Dyson Purifier. If you have Pets this or the smaller models or even the older I would highly recommend. Prior to this i had the 211 auto.

This air purifier is simple to set up and looks great anywhere you have it in a room. I just use the "automatic" setting and let it run. It's very quiet and could be used in a child's room as they sleep.

If you have allergies buy this immediately. It clears all pollen and allergens that cause sneezing and watery eyes. It’s a great product and works well and very quiet when put in automatic mode.

This is an awesome purifier - works in minutes, not loud, and is also attractive looking.

I placed this Blueair purifier between my living room and kitchen, and it’s been excellent. It quickly eliminates cooking odors and leaves the space smelling fresh. It’s also pleasantly quiet, which makes it easy to keep running without any disturbance.

Wow! Just Wow! Amazing air purifier. I have it in my apartment t and this thing rocks. The app is super easy to use and the air is so clean. I leave mine on auto all the time and when it detects something in the air, it gets to work. Pretty amazing. I have a dog and my allergies have gone away inside my house. The air is crisp, fresh and it takes care of any odors. Would buy another one.

If you think you "might" need an air purifier think again because you definitely will not regret it. I was in the market for one and procrastinated buying one because i was unsure of how effective they really were, and not to mention some of the huge price tags they come with ! I stumbled upon this brand over and over throughout my browsing over the past few months and saw really good reviews about them. I have had this product for a little over a month now and i noticed results within the first DAY, its very efficient with picking up dust, odors, smoke, pet hair and has made a day and night difference with my allergies. Also the app is really neat and very easy to use and setup. Looking forward to purchasing another in the near future! Overall this is one of those products that deserves way more than just 5 stars lol !

So far so good! This has helped a ton with the air quality in our house. We added a golden retriever to our family and I can see dog hair collecting on the outside of the unit. It has different settings, the higher settings are loud but the lowest one is quiet. I just adjust mine a# needed. Most of the time I don’t mind the high setting.

With the wildfire smoke and yearly allergen cycles we decided to pick up this purifier. What a difference its made in our daily lives! Allergy symptoms are down and its had thr added benefit of working to clean the air after we cook. …which I didnt even realize was polluted. Beautiful design aesthetic, incredible performance, and a healthier lifestyle, can’t recommend this enough.
