Customer Ratings & Reviews

I first used an air purifier a few years ago at my job where dust was a problem. It was small, but it helped a little, especially with my allergies. A few months ago, I pulled it out while I had a sinus infection and it helped slightly, but it's a very small unit and it just wasn't sufficient for my bedroom or living room. I wanted something bigger, and this Blueair Air Purifier showed me the difference a bigger unit can make. I knew this unit was bigger than the little one I have, but I could not believe the size of the box when it arrived - it's really big (almost 19 inches tall, 11 inches diameter). What is surprising is that even with it's large size, it's really lightweight. This is good because there is no handle or grip, so it takes two hands to pick it up. Of course, the most impressive feature at all is how quiet it is. They are not kidding! The air intake the side of the unit, which has an outer filter. This filter, which feels a little like a loose-weave fabric, and this is removeable and washable. The air comes out through the top. In the center of the top are the controls. These are buttons, but they are more like a touchscreen, as a light touch is all it takes to operate them. Blueair also has an app that can be used to control the unit as well. This is good because in an effort to minimize the buttons, there are a few functions that can be controlled with the buttons, or combinations of buttons, held for various amounts of time. In other words, if you don't want to use the app, expect to memorize some button combinations and/or "press and hold" times to control things like changing the LED brightness and child-lock. If you use the app, it is much easier to manage these controls, and even have greater control. Here are some of the great features of this air purifier: - Cleans the air of a large room in about 30 minutes - Clear labeling of the buttons which are easy to use due to their touchscreen-like sensitivity - Child-lock to prevent accidental changes to the settings - Washable outer filter and inner filter is less expensive than a lot of other brands - Air purifier notifies you when it's time to change the filter - Outer filter is washable - LED's are bright if you need them to be, but can be dimmed to the point of being off completely - Smart device app available for greater and easier control Here a couple of things I wish it had, or did differently: - No handle. It cannot be easily lifted or picked up with only one hand. - There is no timer (meaning no option for auto-shutoff after 1 hour, 2 hours, 4 hours, etc). It does have a schedule feature which I'll explain below. - I had trouble a couple of times getting it to reconnect to WiFi after unplugging it. When I moved it to another room, I sometimes had to disable and re-enable the WiFi feature to get it to connect. - Some features are only usable with the app (such as scheduling), and other features, like the LED brightness, require pressing combinations of buttons to adjust, which are not clearly labeled and can be tricky to memorize until you do. Using this air purifier with the app gives a few extra features, including being able to control multiple Blueair Air Purifiers (if you have more than one, and they don't have to be the same model). One that I particularly like is the fan speed. The unit has 3 fan speeds, which can be adjusted with the buttons and the LED will indicate the selected speed. However, if you change this in the app, it has a slider that allows you to adjust the speed anywhere between these levels, giving you the ability to fine-tune the speed. I really like this because I found that anywhere from the lowest setting to about 1.5 was barely audible to me. Speed 2 is where I could start really hearing the fan blowing. The unit contains a noise shield, which I believe makes quite a difference. Additionally, it seems to keep the fan noise at a lower pitch, which makes it more like a white noise and less disturbing in the background. It also has a "night" mode, which disables the LED's and turns it down to the lowest setting to essentially eliminate the noise, but if you sleep with a fan on at night, you can go higher than the night mode provides and your fan will likely drown out any noise from this unit. There is also an LED light on the side of the unit that is color-coded based on how clean your air is (5 levels), so this should change if the room air is "dirty". Mine measured clean from the start, so I haven't seen this yet, but opening the windows on a pollen-filled day, or an evening of a lot of cooking might be a different result. The app also shows this as well, with a graph to show how it has changed over time (assuming the unit is running). One feature I wish this model had was an auto-off mode. Instead, it has a schedule, which can only be programmed in the app. You can set multiple schedules right down to the minute. However, if you just turn the unit on, you have to manually turn it off, even if you create a schedule that puts the present time in the middle of that schedule. The scheduler only works if the unit can enter and exit that scheduled time without interference. The larger and more powerful (and therefore more effective) Blueair Air Purifier is a really good choice if you are using it in a larger space. It does not require the use of the app, but if you decide to download it onto your smart device, you will have a very easy time operating this unit. If you value less noise and do not feel the need to run the unit at max, this is the quietest air purifier I have ever used. Overall, highly recommended! -

Very easy to setup/use and is whisper quiet. It is a nice looking purifier for the room.

I chose the Blue Pure 311i Max to replace my older model BlueAir Filter. The new filter can connect to Wi-Fi for remote app control. The app seems to report the air quality on a chart, but so far, it's saying my existing air is "Excellent," which may be because it replaced the existing filter, which was also doing a decent job. However, some PM 2.5 was detected in the room (PM2.5 is "Fine particles", such as "fine dust, exhaust, bacteria, and pet dander"), so it's working already. The app controls Fan Speed (lower speeds are quieter/silent, higher speeds filter quicker), Automatic Mode, Night Mode (extra quiet and dimmed lights), and a child lock function. Of course, the app will tell you how much life is left in your filter as well - and yes, the device has a filter warning light on it; however, the app may let you know how close you are to that 'replace filter light' coming on. The app has a welcome home feature to filter the air as you get closer to home, but you have to make sure you give the app (1) background location permission, and (2) unrestricted battery (no optimization). My previous blue air filter did not have Wi-Fi features, so this is a nice upgrade. I will tell you immediately there is a different quality in the air and a different feel in the room on the first day of its running. I feel more relaxed (my skin even) in this room than before I replaced it. There was previously only one or two other places (outside the house, such as other businesses) where my skin had this relaxed feeling, probably because of good filtration there (I suspected). Now I have it at home. Time will tell if this remains true or if it's just like a placebo effect appearing because I was hoping for something like this. Most air filters work best in a room with closed windows because, with open windows, you are filtering outside air with an endless supply of allergens. In reality, most of us do occasionally open the windows, especially (in my case) in fall and spring (which may be the worst time for allergens) when temperatures outdoor are nicer. It's unclear if doing this will shorten the filter life. I chose this product after already owning another BlueAir purifier, because i was happy with the brand. This product is even better than my last one, and I recommend this especially if you have allergies,

If you are in need of a filter that has excellent auto detection, isn't too loud, and looks fairly good while sitting there? Here you go! Setup: to get the most out of this filter, you'll want to install the app. You can use it without it the app by using the buttons on the top of it, but to get the most out of it...get the app! The app is easy to set up. I already had another Blueair filter, so adding this one to my app was very easy. Following the instructions it only took a few minutes. Use: You can use this in manual mode, or automatic mode. In manual mode you set the fan speed and it just sits there and runs. In automatic mode, it senses particles in the air and adjusts fan speed as needed. This filter only senses one "type" of particle (which is basically smoke and actual small particles in the air). This overall works very well. There are some higher end filters that are able to detect multiple different types of particles, but they do cost much more. If you are using the app, you are able to see what the filter is sensing, and also change modes. You can also set schedules. This filter is in my bedroom, so I have it scheduled to go into "night" mode at, well, night. This turns off the LED's on the filter, and also sets the fan to its lowest speed. You are also able to buy different colors of "wraps" if you choose. They slip on and off the bottom (the gray part in the picture). Overall: This is a nice filter, and isn't too noisy even on its highest setting. I set it on auto mode during the day, and it seems to sense stuff very well. I burned some food cooking (which is on the floor below), and I went upstairs and it was on high working to clean the room. 30 or so minutes later, it was back down on low.

This is the air purifier you are looking for. Comes in a nice sized easy to unbox package. Comes as 1 unit that doesn't need to be assembled. Just take it out of the box, plug it in, and you are good to go. Comes with an instruction manual that I would recommend to read. You have to download the app to pair your phone using bluetooth which is very easy to do. The air unit itself is very light surprisingly so it's easy to carry and move around to different rooms if need be. All the buttons are on the top of the unit, making it easy to access and so that you don't have to bend down and strain yourself to see the buttons if they were on the front of the unit. This also has 3 speed settings, which are useful depending on the environment, and unlike my experience with other units, even on the 3rd speed which is considered "high", it still is not super over powering to the point of being annoying. You can run it on high during the night if you have it in your bedroom and would not be distracted by this. The app like I mentioned is great and easy to use. Very intuitive. You can turn it on/off from the app, or adjust the speed. From the app you have more than just the 3 standard speeds as well. You can do fine adjustments and do 1.5 or 2.5 if you like instead of full speed changes. You can also turn off the led light if that is distracting or enable the child lock. The app also gives you a status of the filters so you know when to change them. It also tells the quality of the air and if you were running it it will show you the time remaining until the air is cleaned. Very helpful and useful stuff. I have no issues with this and would recommend it to anyone.

Works great! Not too loud. I have noticed an improvement in my daughters allergies since using this.

I just love this air purifier it keeps the air fresh

Great air purifier, quiet and efficient. I love the application that shows when you need a new filter.

This air purifier has a modern attractive aesthetic but the performance is nothing special. Even though they call it "HEPAsilent" it seems just as noisy to me as any other air purifier I've had, so don't buy the marketing on that. To me the fan also seems a bit high pitched and shrill at higher speeds compared to other air purifiers I've had. At very low speeds it is quiet, but it's also barely moving any air so it's hard to count that. The app is a neat feature to have and seems to work great.

Easy to setup, runs very quiet. The automatic setting is ideal forour setting

Quiet and great at dust particle reduction thank you

We love the auto feature as it kicks on by itself when cooking odors are strong
