Blueair - Blue Pure 311i Max 387 Sq. Ft Smart HEPASilent Air Purifier - White/Seabed

The Blueair brand of air purifiers were new to me, so I did not have any special expectations. I decided to go with the Blue Pure 311i model since it was the best size for a medium-sized room. I was pleasantly surprised when I unboxed the product because it was much bigger than I thought it would be and looked classy with the grey colored fabric that surrounded the filter. I also liked how the top of the unit had a central area for all the controls for manual use along with all the lights to alert you to the different settings that are available. It was easy to set up the filter and after downloading the Blueair application on my smartphone I was impressed with the various features and controls that it added. I liked that it would show you the air quality outside of your home based upon allowing the location service enabled and then it would also monitor the air quality inside the room where it is used. I initially set it up right next to my bed because of the severe allergies that I have, and I was looking forward to having extra relief that I expected from the HEPA filter. I was impressed with the ability to setup schedules of when it could run, adjust a night mode for it to reduce the brightness of the control lights on top of the unit, and to turn the unit off or increase/decrease the fan speed. After setting up the unit and researching the expected length of time before you needed to replace the interior filter and found out that it could last up to 9 months but that the app keeps track of when you need to replace it. The Blueair app also has voice control assistance via Alexa or Google Assistant activation. It also has a feature called Welcome Home that you enable to turn off the machine when you leave home, and it will turn it back on when you are getting close to your home. The application features are an excellent way to get the best use of your air filter with the latest technology. Blueair air purifiers also have the Energy Star certification for low electricity use, so you do not have to worry about leaving it on for too many hours. I have enjoyed the change of the air quality in the two rooms that I move the air filter to depending on if I am working or sleeping and it has made a difference in my allergies already. I will be looking for more Blueair products for the rest of my home now that I have tried out the brand and am pleased with the high-quality work.

I absolutely love this air purifier, and have to say it is one of the most effective purifiers I have used! The purifier is the perfect size to put in the corner of any room, with a neutral, simple look that is stylish and fits any room you may put it in. The controls are extremely simple, with a power button and a filtering-level adjustment button to cycle through the 6 filtering modes. You can connect the purifier to your phone too via the Blueair app and wifi for more advanced controls and visualizations of the air quality in your home, a neat and useful touch! This air purifier is extremely strong as well, definitely enough to allow the purified air to circulate a medium sized room in a home or bedroom with ease (the highest mode honestly could double as a fan for a room)! It should be noted that while this product is advertised as HEPASilent (which as a sidenote, the noise output from this purifier is very low, and almost all settings are silent as advertised except higher settings with standard ambient air blowing noise!), it is not indicated that it is an actual HEPA air purifier, but, I have dust and pet allergies, and with a cat present in my home and dust circulating at times (ie. with hvac running), running this air purifier 24/7 in common spaces in my home seemed to improve my indoor allergies, which, while I am no scientist and can't make any scientific efficacy claims with certainty, I happily observe while running the purifier! Overall, this air purifier is a great and very helpful addition to any home, and has greatly improved the quality of air in my home!

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.

Before agreeing to use and review this Pure 311i I have purchased several other Blueair air purifiers and find the brand to be the best: I like the Scandinavian minimalist design with different coordinating fabric prefilters. They run quiet with a simple color-coded visual of air quality. I have the 411 in both my kids and my own bed room and I feel like we all breath better having these run silently while we sleep. The 311i is a larger model, the largest from Blueair I've tried: and is great for my 24 x 20 ft living room, while its size means that it isn't invisible, I feel like I can put it in a corner next to the sofa and it gets good airflow without being obtrusive. Like I expected: it runs quiet and I've enjoyed the color coded notifications of my indoor air quality. I also like that this one now comes with a mobile app: professionally I'm a product manager and I'm obsessed with analytics, so it's great to be able to get historical context around when my indoor air quality caused the 311i to run harder and how that indoor air quality related to the outdoor air quality at my house. I found it pretty straightforward to setup the app, easier than setting up some other IoT devices like lightbulbs or thermostats. I was hoping that the air purifier was compatible with the Matter smart device standard so that I could add it to my other Smart Home suite of devices but given that the app and air purifier are both nice I'm happy with them in their stand alone format.

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.

I am so happy with this air purifier. I live in a condo with neighbors on both sides and i was bombarded with odors that were unpleasant. I have found this purifier has solved that problem and has helped my allergies as well. It is quiet on the automatic setting and very energy efficient. I highly recommend it!

I recently started using this air purifier, and I’m genuinely impressed with how it clears the air. It’s amazing how fresh the air feels now, much better than what I’ve experienced with other big brand air purifiers. The difference is noticeable—I can really tell that the air is cleaner and more refreshing.

The air quality feels amazing. I like the connectivity of the air purifier to an app. Very easy to use. Very informative.

This is what I imagined an air purifier should be in 2023. It comes with an easy-to-use app, it's quiet, and above all, it filters the air your breathing everyday. This unit has a soft outer layer and is easy to pickup and move around the house if necessary. Controls are very simple to understand and operate. You can download the app for iphone or android. There's a quick install, pairing up with your phone and your wifi network. You plug it in, and it starts to do it's job. If you would rather hit buttons manually, they are on top of the unit and are fairly easy to understand and control. The first thing you see once you have the app running is a graph with a rating from very polluted to excellent air quality. Then you have a fan speed from 0 to 3. You begin to hear the fan at 3 but it's very tolerable even on high. You can put a child lock, run it in night mode, or set it to auto filter the air as necessary. Night mode turns down the LEDs and the fans while you're trying to sleep. You can also see a filter rating so that you know when to replace. LED's can be adjusted here as well if you want to turn them down or off. At the bottom of the page is a schedule where you can change air purifier settings based on your own hours and days. I've set my setting for an 8am to 5pm Monday through Friday while I'm at work. I was surprised at how quiet this unit is. It's nice for a soft white noise at night. I typically don't turn the fan higher than 2 because the air quality is usually excellent in my apartment. This unit can purify almost my entire apartment in 30 minutes. I have approximately 1100 square feet. Filters are also suprisingly affordable for this unit. The only time that I've need this purifier to work right away it passed the test brilliantly. It was after we burned our food on the kitchen stove this past week. Within about 15 minutes the burned smell was completely gone. I didn't even realize the air purifier was doing it's work. I would recommend putting this unit in a large area or a room connected to the kitchen because it can filter out air and strong smells quickly. It's also nice for the peace of mind that pollens, pollutants and dust are removed from the air that I'm breathing in my home. I highly recommend this unit if you're considering an air purifier. It's simple to operate, it works perfectly, it's quiet, and it looks good in any room due to it's light color and rounded edges. An added plus is there's an extensive amount of literature and support on their website.
