Probably best bang for your buck. No issues so far

Wow i am super impressed. So i had a air purifier in my Livingroom that was a bit smaller than this one but not by much. When i received the box from UPS it was big but i was very surprised how lightweight it was. Now my old one has been running for almost a year and its way louder even on the lower setting its still pretty loud. This Blueair is so so quiet i did not even think it was running after a few hours when it had literally cleaned the air in my house. They have a few different models as small as one to clean the air in like a smaller bedroom and all the way up to one size bigger than the one i got. This one cleans a room about 928 square feet in about 30 minutes then it's sensors can tell the air quality and it will adjust the speed of the air purifier to a slower speed. Like i said mine has gone through the initial cleaning and now it's whisper quiet. I had to put my ear rite up to it to hear if it was even running,It is super quiet. As you can see in one of my screen shots of the app running on my phone where i initially turned it on and the air quality was not very good and that was with my other air purifier running constantly at a way higher speed for almost a year. So turning the blueair on and seeing that my old one was not even remotely doing the job was kind of disheartening because i feel like i have been running my old one and all it was doing is wasting my electricity and humming in the background and not doing what i paid over $130 for it to do. Another nice feature is the outer material comes in an assortment of colors, so you can match your paint or furniture so it doesn't stick out like a sore thumb. It was super easy to set up with the app and i had it out of the box and up and running in about 3 minutes. As you can see from the screen shot on the app the air quality in my house whent from bad even with my old air purifier running constantly for almost a year to very clean in under and hour. This is one of the best investments i have made in a long time and i can tell by the amount of dust in the air and it smells so much better in my house that this was a great purchase and its doing a great job. Like i said also if you have a smaller area to clean the air in they make several models that are less expensive so you can adjust your budget and save some money or you can buy the bigger ones put them in the smaller are and clean the air so much faster. All in all this was a great purchase and well worth every penny.

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!

We have two dogs, One is long haired and he brings in a lot of dust and dirt. This helps so much not just for our breathing but keeps the cleaning down also. The style is modern. A little bigger than I thought but perfect. It’s really cute. And it’s not loud.

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.

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

Nice filter, air quality improvement is noticeable. very quiet on low and looks nice.

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.

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.

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.

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, 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.

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.

Quiet and works well, has great features and has a nice modern appearance

Quiet,efficient, and good looking. Auto function is great for cooking and woodstove. Noticeable difference in air quality.

It works perfectly,love it. It also helps a lot for clean air.
