Customer Ratings & Reviews

Ever since I found out as an adult that I have severe allergies, I’ve made it a point to make sure my house is treated for allergens, and that includes the use of air filters. I now have several different brands and types of air filters in my house, and while I have no objective evidence - like test data - of better air quality, I can say that anecdotally my allergies and the quality of my sleep has never been better. When I focus on features, ease of use and design, I’m comparing it to Dyson products, 3M and Molekule (which I all own). SETUP AND EASE OF USE In terms of setup and simplicity, the Blueair is easily one of the best. I had issues connecting my Molekule to my Wi-Fi network, the 3M doesn’t have any smart features, and the Dyson was easy to setup. (Granted, Wi-Fi app access is not necessary). I plugged it in, the lights on the display came on, and after downloading the app, the app immediately found it and immediately connected to my phone. It comes with a manual which is an easy read and simple to understand, but it’s somewhat unnecessary. At least when it comes to the controls, it’s very intuitive. There’s two buttons, one to turn it on and off and the other to switch between fan speeds. There’s 3 fan settings with the 4th putting it in automatic mode and the 5th being night mode which sets the fan speed at the lowest settings and sets the brightness of the display to the lowest. Bottomline is setup and ease of use is an A+. DESIGN With air filters, especially larger ones, are meant to be focal points in your rooms. They are supposed to be placed away from walls so it’s difficult to keep them hidden or otherwise have them blend it. Bottomline is that the design of the air filter does matter (at least to me, and presumably most people). You have the Molekule which to me is a sophisticated looking filter, to me it’s the filter Apple might design. At the bottom you have the 3M which is definitely function over design (it’s a large ugly black box). Obviously design is subjective, but I find the Blueair filter to be very attractive. It starts with the fabric filter cover that filters large air particles on the outside. If you don’t like the color, there are other colors that fit your look. The interface blends into the top of the filter and is not distracting (vs. Molekule which has a small OLED screen), but basic. To me it almost looks like a round laundry hamper, but to me, it’s handsome and I don’t mind having it on display in the middle of my room. AIR QUALITY AND SOUND As I said before, I really don’t have a way to test the filtration quality. I rely on the app, which I admittedly had to educate myself on, and anecdotal evidence. As I said, my quality of sleep has improved and my allergies are better. From my perspective, it works well. The app tells you the air quality based on particle pollution, or PM. It also measures AQI or air quality index. The AQI index appears to be based on your location, so the app is pulling that information from external sources. So you’ll notice that the AQI is listed as outdoor. For indoor, it simply tells you whether the air quality is “Excellent” or otherwise (i.e. Good, moderate, polluted, etc.). The filter can apparently capture PM of 2.5 which includes fine dust, animal dander and bacteria. I don’t think it actually tells you what it’s filtering (again, I’m ignorant on some of the science - I have to take this at face value). The other big thing is sound. The Molekule air filter can sound like a jet engine, as does the 3M model. The Dyson does too when it’s on full blast. The Blueair is quite the opposite and is very quiet, even on the loudest settings. It apparently has a “noise reducer” on the inside. Now, some people may like the low hum of an air filter as white noise when they sleep - something to consider when choosing an air filter - while others might think it’s distracting. The Blueair is extremely silent; on automatic settings I can barely hear it even at night. It’s quite impressive. MAINTENANCE I think a major factor in deciding on an air filter is maintenance costs. First there’s the hurdle of initial costs, but if you don’t think you’ll need to change the air filters - you probably do - you’ll soon realize they’ll need to be changed. Just look at one of your filters after several months and you’ll want to change it. Then comes the frequency of having to change any filter or filters and the cost. Molekule and Dyson brands fall on the expensive end, with a suggested replacement time of every 6 months. It’s about $60-70 to replace Molekule filters (in my model, there are two filters). The 3M filters are cheaper, about $13 each, but they require more frequent replacement. This particular model recommends filter replacement every 6 months, and the costs if you opt for a subscription (which I recommend so you don’t have to remember to order them, and you get a few dollar discount) is about $44. This gets you a replacement filter, but you still have to perform some maintenance on the outer fabric cover. The manual recommends vacuuming the outside (if you see dust on it) with a brush vacuum attachment. Or you can opt to wash it and air dry it. When taking into account the Molekule, which requires the purchase of two filters, I certainly don’t mind washing the outer fabric every so often to prevent my from paying for a second filter, so that’s another bonus of this model. CONCLUSION This is a great looking, quiet, air filter that has relatively low maintenance costs. Yes, it is a little ont he expensive side compared to some other options, but taking everything into consideration, it’s a great option. Especially when you take into account that it’s intended to cover a large area like a large bedroom or even a living room. I can comfortably say tha the use of air filters (this model specifically, but also just the use of air filters in general) has increased my quality of life at home; especially living in an area where my allergies can be difficult to manage.

The Blueair 311i Max air purifier was designed in Sweden, which might explain its no frills design. It is short and squat (19 x 11.5 inches) and has a cloth pre-filter that can be washed and/or swapped out for one of a different color and design. There are no fancy controls to show % filter life or a numerical air quality value. The control module is a very thin circle that controls the 4 fan speeds. There is a colored light bar on the side that indicates 5 stages of air quality status from excellent to very polluted. There is also a light that comes on to indicate that the filter needs to be changed. This air purifier is for medium spaces and per the manufacturer can clean up to 387 square feet in 12.5 minutes or 929 square feet in 30 minutes. My air quality is “excellent” so I wasn’t able to verify the claims. It uses both electrostatic and mechanical filtration and captures particles down to 0.1 microns in size. It is said to remove cooking odors, smoke, pollen, dust, pet dander, mold, bacteria and viruses. It is very quiet. The noise level ranges from 23 dB at the quietest setting to 50 dB at fan setting #3. I couldn’t hear it at all on the auto or the night settings and had to look at it to know it was turned on. The air filter comes ready to pair with an app. There is an option to cancel out the pairing and not use the app. I prefer to not use apps whenever possible because I don’t like giving up my location and personal information or cluttering my phone. However, due to the design of the 311i Max, the app is almost a necessity. It is possible to set the child lock on the control module and to adjust the brightness of the lights by pushing 2 buttons simultaneously, but it’s not easy to do. The app can be used to change the fan speed, activate child lock, adjust the brightness and check the filter status. It is also possible to set a schedule for the fan mode and brightness by the day of the week and time of day. If you don’t mind letting the app always know your location, there is a Welcome Home feature. The air purifier will go on standby when you leave home and turn back on when you get close to home. I had no problems pairing the air purifier to my phone. There were warnings about having to disable the VPN and about needing a 2.4 GHz wireless connection. I didn’t have to change any of my wireless or security settings. It is lightweight and easy to move. The plastic circle with the manual controls seems flimsy and overly sensitive. Just getting my finger close to, but not touching it, can activate the on/off button. A couple of times just walking by it turned it on. There is a section in the manual about potential TV interference - maybe due to the electrostatic mechanism. I get my TV reception via a free TV antenna (not cable) and I have the air purifier about 30 feet away from the TV. I did experience some blipping and distortion in the TV reception when the air purifier was on and the reception did improve when I turned it off. But since the distortion is random I couldn’t verify that the air purifier was the cause. The Blueair 311i Max air purifier should do a good job of purifying the air in an uncomplicated manner. If set on auto you wouldn’t even know it was there.

This is a good quality air purifier! Its basically just a filter with a fan on top. I used the filter it came with and while it did make the air feel more “clean” and crisp, I could still smell some light household odors. I did some research on other compatible filters and I ended up purchasing the allergen filter. There isn’t much information or customer feedback about the filters online, so I decided to just go for it. Out of the box I noticed a more refreshing flow of air coming from the purifier. I left and returned home after about 8 hours and the air smelt completely clean and fresh. There were no lingering smoke or cooking odors at all! Definitely worth it as long as you upgrade from the stock particle filter to either the smoke blocker filter or the allergen filter. The app is nice to have as well. You can turn it on or off, adjust the speed and view the air quality history. Definitely recommend this!

It works great and having the app to be able to control it is amazing. Same with the filter life on the app to remind me when to change it. I would recommend thing product and buy another too

This is a great tool to add to the home or office space. The design is modern and fits into any space without standing out. The best part about using the product is the app and the ability to control the unit from anywhere. To save on cost it has an auto feature that will run based on the quality of the air. Another cost saving feature is the ability for the unit to turn on and off based on your location via cell. depending on the fan speed it can be very quiet to somewhat noisy. If ran on Auto and the fan is at full power, it doesn't stay noisy for long periods of time depending on the situation at the moment. The sensor is able to pick up very quickly to smoke, aerosol fragrance sprays, oil diffusers, you name it, it can sense it and act accordingly.

I purchased 3 of the Blue Pure 311i Max for our house- one for each floor. These replaced older generation Honeywell HEPA filters (lasted 10+ years). I've had these for over a month now and am very happy with the design and operation: high efficiency HEPA filter media, very nice design with the colored fabric cover, and much quieter (but provides just enough white noise for sleeping). Five Stars. Great pricing at BestBuy too.

As a Winix customer of over 15 years, this was my first Blueair purifier purchase. With 2 cats, allergies and living on a gravel road (lots of dust), for such a lightweight unit - WOW - such amazing results! Blueair has won my business and my loyalty going forward. Maintenance/cleaning is so much easier than Winix and most importantly, it certainly outperforms my Winix XLC, Winix 5500 & 6300.

Quiet, easy to use, and not too big. Cleans and purifies the air quickly and doesn’t take up much room. Highly recommend grabbing one of these if you suffer from allergies.

Quiet, effective. I use auto setting usually and air quality indicator light color displays blue (the best level) so I questioned whether it was working until a neighbor had a wood fire and we could smell it in our room. The indicator light displayed orange and soon went back to blue. After a few weeks of using all night, I breathe better at night.

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 bedroom and a larger one for living room . Very happy with both and definitely recommend.

Easy set up easy use actually matches the furniture and pretty quiet .theres ecen a noticable difference in teh air quality now, the air no longer smells stale and moist

Purifier is very quiet and easy to use moving it from living room to bedroom. Air quality feels cleaner and doctor approved.

I have had a lot fo air purifiers in my home over the years. This is my second BlueAir air filter unit. This model is much better than the first generation. It is super quiet and the fabric sleeve can easily be washed. The fabric sleeve is the first layer of filtration and prolongs the lift of the unit’s HEPA filter. The unit has an okay mobile app thst connects to the filter and provides data on air quality and run time. Id say the best feature is the quietness of the unit and the washable sock.

SO MUCH QUIETER THAN THE CLASSIC SERIES AND WAY LESS BULKY SHAPE. DOES A GREAT JOB CLEANING THE AIR

It’s worked out great in my small apartment. Its set and forget with an auto feature that kicks on when I’m cooking or something else pollutes the air. It never gets too loud and it’s got a decent look to it. The app is also nice for changing settings and monitoring air quality in my home.

Easy set up. Works great! Fast delivery! We would buy again.

I bought this Blueair for my bedroom. Keeping it running at level 2 during the day and at the Sleep level at night seems to be working to help with alleviating allergies. It's larger than I thought it would be, but it fits on the floor inconspicuously enough. Best features include the wifi connection to a phone app and the sleep mode - can't hear a thing but I know it's running.

Unboxing reveals the air purifier itself with a light grey pre-filter and the user manual. Purifier is of a solid plastic construction with rubberized feet. Filter is well-designed and small 12.5” footprint fits in perfectly in my home. Power cord is long yet cannot be disconnected from the purifier. Fan is quite large and is whisper quiet. On low, the fan is barely audible at 23dB and is still impressively quiet on high at 50dB. 250 cfm fan moves an immense volume of air and is advertised to clean 387 ft2 in only 12.5 minutes. Refined design with only two capacitive touch buttons. One for fan speed, night and auto modes and another for power. Fan speed of 1 is 12%, 2 is 56%, and 3 is full steam ahead. Wi-Fi LED indicator light doubles as a notification for when a filter-change is due. Blueair’s RealTrack algorithm accurately calculates filter life to provide a more precise time to change the filter. Filters are marketed to last from 6-9 months. Purifier also has a child lock to prevent unwanted tampering with settings. Top part of the air filter easily twists off to change the filter. Air purifier uses 3 stages of filters. A fabric pre-filter on the exterior is washable and reusable. Main filter removes 99.97% of particles as small as 0.1 microns and a final activated carbon layer eliminates unwanted odors. Pre-filter also comes in 5 elegant colors sold separately to customize the look of the purifier. Blueair app is well designed and feature packed. An account must be made to access the app’s features. Connection is simple, simply choose the product family and the filter appears via Bluetooth in the app. After Bluetooth connection is established, one can add the filter to a 2.4GHz Wi-Fi network to control the filter and monitor data anywhere. Features of the app include a chart comparing the air quality reported by the purifier with the outdoor air quality, granular fan speed control, LED brightness, schedules, and a Welcome Home feature. Welcome Home feature automatically turns the filter off and on when in proximity of the house. Blueair filters are compatible with major voice assistants as well. Overall, the Blueair Blue Pure 311i Max is the stylish, no-nonsense air purifier of the future.

This is by far the best air purifier that I have tried. I bought several high tech super smart air purifiers before I bought this one and they were all disappointing. The Blueair air purifier is quiet and efficient. The auto mode works very well to detect when I'm dusting or cooking or doing anything that increases particles in the air.

Super lightweight. Very quiet. Easy set-up and makes a real difference in air quality
