Customer Ratings & Reviews

Love this air purifier. The city flushed the dear line in front of our house. Odorscame up through our line and we had problems getting rid of the order until we turned this on.

Okay this thing is awesome. My office always smells like pet dander so i thought I’d give this a try. Left it running for just 1 day and its already SO much better! So happy with this purchase.

I got this just on time for sprin pollen season. Keeps my apartment dust-free and my breathing hasn't been better. Worth the money for sure!

I have been waiting a few months in order to review this. So far I am very happy. it picks up any smells all they way from my kitchen.

This product has a very interesting design as the filter is part of the structure of the device and it is quite solid. The device also includes a washable fabric prefilter. This fabric functions both as a filter and as a nice decorative cover over the carbon/particle big filter. Overall, an ingenious design including the structure and the touch controls. There is also an excellent app for the Blueair filters. I have another larger Blueair, so I was able to just add this filter to the same app. Controls are so intuitive you may not need to even look at the user manual which is also well done. The manual does show the parts of the system including a ‘noise/shield ring’ to reduce fan noise. There is a sleep mode which can reduce the fan speed such that there is no perceptible noise. The only way to tell the fan is even moving is to place your hand above the unit to feel the breeze from the unit as it filters your air so quietly. You also have manual controls on top of the unit which are touch controls - very nice, and they work great. One caution is to avoid touching the on/off button-area while changing fan speeds. You'll do this once I think and accidently turn the unit off. It is one small area that the engineers should look at, I'd suggest a double touch to turn the unit off would be a slight improvement. I recommend using the devices WiFi capability and installing the Blueair app. Open the app and it will show you available devices, pick the picture matching your unit and the rest of the steps are guided by the app. You do need to have Bluetooth on as well. Sometime products require several times to get connected, but this unit did it in one step and quickly - tip of the cap to the programmers and engineers at Blueair. Unlike cheaply made units, this one has the quiet fan speed which is very important if used in a bedroom. The entire unit is made of quality materials and the engineering is superb. I would highly recommend this unit for a bedroom or small living room.

Great equipment and easy to manage. My family has some allergies and the Blue Pure 311i helped reduced the allergies.

We love our Blueair! We returned our Dyson purifier that costed 4x as much and does not compare to the quality of Blueair! We will be buying more!

I have two of these units. What I like most is the "auto" feature....this unit ramps up when conditions in the air call for additional filtration.

Works great this is very easy to operate—- has an app you download to your phone—- simple to do

This does the job great. Filters the air in an auto body shop office. Makes a big difference.

It seems to have problems where the timeline doesn't remember what the past air clarity and always sets it to it's current air clarity

Best decision i made was to purchase this air purifier!

I can only run this for short spells because the plug gets very hot & I'm afraid of fire. I only plug it in to wall outlets as instructed but it still gets much too hot.

Great air filter we actually have a couple now and love them

Good looking and quiet air purifier. It’s a lot bigger than the pictures make it seem, with an overall size that takes up the same amount of space as a small ottoman. I didn’t remove the filter cover, but it feels like the filter spans a full 360 around the body, so it pulls in air from all sides. The purified air then comes out vertically through the vented top, which you can feel as you stand over it. It doesn’t come with a remote, but you can monitor and control it through the Blueair phone app that’s free on Android and iOS. And I guess this is what sets it apart from other HEPA air filters, because not only can you get a live feed of the current air quality (down to 2.5 microns!), but also a readout of the current outside air quality, and of course you can use it as a remote. Unfortunately, you’ll have to look at higher end models if VOC detection or UV capabilities are a priority. In terms of day to day use, air purifiers are kind of a set and forget thing. What I love about this one is that it has an Auto setting that automatically increases the fan speed depending on the quality of the air it’s pulling in. It mostly always stays at a low level that I can barely hear, but it ramps up quickly if someone has been smoking or vaping nearby. At the highest level, there’s clearly an audible whooshing sound with a little bit of intermittent whirring. However, it’s not so loud that I feel like I have to speak over it or blast the TV. Outside of the Auto and 3 speed settings, there’s a Night mode, which I’m honestly not sure what it does. I know it turns off the blue illumination light on the front of the purifier and dims the display, but I don’t know if it does anything in terms of limiting fan speed. What’s also pretty nifty about the Pure 311i series are the interchangeable prefilters. This is the cloth that wraps around the outside of the purifier. While I like the gray mine that came in, there’s currently 2 other colors available that I can swap over to and I can only imagine the third party designs that could be available in the future. Overall, if you’re looking for an attractive medium room air purifier I highly recommend checking out the Blueair Pure 311i Max. It’s has a HEPA filter, looks good, works well, is generally whisper quiet, has a customizable cover, and an air quality live feed. Works great on smoke, vapor, and pet smells.

I have been using a larger Bluair purifier for my kitchen and family room now for over 2 years and it has been an outstanding product. I wanted something small for my bedroom and bath and had the opportunity to test and review this new Bluair 311i Max. Bluair claims it cleans 387 sq. ft. in 12.5 minutes and 929 sw. ft. in 30 minutes. This is a really nice purifier. It is a great size and is fairly light weight. The manual instructs you to download the Bluair app and connect to Wi-Fi. When you first turn on the unit the Wi-Fi indicator will blink. The manual says to have the unit within 15 feet of your router. I first attempted to connect the unit in my bedroom and it was too far away apparently as it would not connect. I moved the unit to my office where the router is located and it connected right away. The app walks you through the set up which includes connecting to the Bluetooth on your device. Not sure why this is required as after this step is completed you no longer need to have Bluetooth on in order to use the app. After I finished setting everything up, I moved the unit back to my bedroom and began testing it. The unit itself has a series of buttons on the top for on/off (standby), fan speed, auto mode and night mode as well as an indicator to let you know the filter needs changed. There are indicators for the 3 fan speeds. There is also a colored light on the front of the unit to let you know what the air quality level is. If you push a combination of the fan speed and on/off button you can change the brightest for the lights. I tested all these functions and everything worked as expected. I primarily use the app to operated the unit. The app provides data on outside air quality (not sure how it knows). When you access the purifier, it provides data on the inside air quality. What I really like about the app is you can turn the unit on and off (standby), adjust the fan speed, set auto or night mode, set child lock and adjust the brightest of the lights. What is really interesting when adjusting the speed instead of just options for 1, 2 or 3 you can have incremental levels between each one and the app tells you what percentage the fan is running at. For example, at fan speed 1 it runs at 12% and fan speed 2 runs at 56% you can adjust between these values. I have been running this around half way between 1 and 2 at 30%. This gives me a good air flow and the noise level is very comforting. This purifier is very quiet. On night mode you can’t hear it at all and even at level 3 it is quieter than many purifiers I have used. Replacement of the filter is easy. Simply detach the top, remove the silencer ring and the sock pre filter and remove the filter. The filters are now expected to last up to 9 months versus some purifiers that last only 3-6 months. The filters are very reasonable at around $35.00 and even less if you have a renewal subscription. I have been using this product for the last 3 days and it has performed exceptionally well. My bedroom and bath smell noticeably cleaner and fresher. It this unit continues to perform as well as my larger Bluair this should be a great air purifier to have. This is probably the best air purifier I have found in this price range. I would highly recommend this product.

One of the standout features of the Blue Pure 311i is its straightforward setup process. It comes with clear and concise instructions, allowing users to assemble the unit within minutes. The filters are pre-installed, eliminating the need for any complicated filter installation procedures. The compact and lightweight design of the Blue Pure 311i further enhances its ease of installation and use. The unit's portability and versatility make it adaptable to various room sizes and layouts. The Blueair Blue Pure 311i air purifier boasts an intuitive control interface, making it very user-friendly. Located on the top of the unit, the touch-sensitive control panel offers a sleek and modern aesthetic. The panel features easy-to-understand icons and functions, ensuring effortless operation for users of all ages. The purifier offers three fan speed settings: low, medium, and high. Adjusting the fan speed can be done with a simple tap on the control panel, allowing users to customize the airflow according to their preferences and the level of air pollution in the room. The display also provides real-time feedback on the indoor air quality, thanks to the inclusion of a color-coded indicator. This feature enables users to monitor the effectiveness of the purifier at a glance. One notable aspect of the Blue Pure 311i is its whisper-quiet operation. Even on the highest fan speed setting, the noise produced remains minimal, allowing for uninterrupted sleep or work. The lack of excessive noise makes the unit ideal for bedrooms, nurseries, or office spaces where a peaceful environment is crucial. The unit comes equipped with a combination particle and carbon filter, ensuring the removal of airborne pollutants such as dust, pet dander, pollen, smoke, and odors. The filter's lifespan varies depending on usage and air quality but typically lasts around six months. The process of replacing the filters is straightforward and can be done in a matter of minutes. The purifier's top cover easily lifts off, providing access to the filters. Once removed, the old filter can be replaced with a new one by simply placing it back into the unit. The filters are readily available and can be purchased directly from the manufacturer or authorized retailers. To maintain optimal performance, it is recommended to vacuum the outer surface of the filter periodically to remove any accumulated dust. This simple step enhances the filter's longevity and ensures its efficiency in capturing airborne particles.

This is my second Blueair Blue Pure product. I upgraded from the Blue Pure 411i to the Blue Pure 311i. I am very allergic to dust, therefore an air purifier is a must in my home. I prefer to have one in each of the rooms instead of one for the whole house. This one was placed in my bedroom. The Blue Pure 311i is almost twice as large as my previous Blue Pure. It was delivered in a huge box. The set-up was pretty straightforward, remove packing plastics, place the dust cover on, then plug in the device. There is an app that allows you to control the air purifer remotely, plus many more additional functions. After bluetooth and Wifi connections were reached, I turned on the air purifier. First I was truly amazed at how this unit is so quiet. The noise shield works great! At the highest setting 3, it's about as loud as a box fan on low. This air purifier is great for my older home as it not only removes dust, it removes pollen, pet dander, mold, bacteria and viruses, cooking odors, chemicals, and smoke. The particle sensor measures the fine particles level. (PM2.5) There is an LED indicator to show the air quality in different colors, from excellent to very polluted. The BlueAir pre-filter can be cleaned in the washer. I have other brands air purifiers in my home that are slowly being replace with Blue Air. Highly recommend.

I have really bad allergies, especially during the Spring and early Summer, so I have quite a few air purifiers from different brands around the house. When I got a chance to try my first Blueair air purifier I had to jump on it. Here’s my review of the Blueair Blue Pure 311i. I’ll give you my overall impressions first and then break it down a bit. Overall I really liked pretty much everything about the Blueair Blue Pure 311i. It’s a great air purifier for small to medium-sized rooms. It's pretty simple to use, has a nice design that would blend into any decor, and can operate very quietly. It also has HEPASilent technology, which traps 99.97% of airborne particles. If you're shopping for an air purifier, the Blueair Blue Pure 311i is a solid choice. The Blueair Blue Pure 311i is a wonderful air purifier for small to medium-sized rooms. It's a breeze to use and has a sleek, modern design. I personally enjoy the ability to set the unit on quiet mode if it’s located in a living room but also can turn it on high if I want some white noise in a bedroom. The Blue Pure 311i advertises something called HEPASilent technology, which claims to trap 99.97% of airborne particles, including dust, pollen, pet hair, and other smaller particles. The pre-filter is there as well and that takes care of the larger particles before hitting the HEPA filter. The air purifier has a CADR rating of 150, which basically means that it can clean the air in a 150-square-foot room up to 5 times per hour. This rating is only true when it’s operating in full speed mode though, as sleep mode will be quieter but not clean the air nearly as quickly. As with any air purifier, you’ll need to replace the filters on the 311i occasionally. Blueair recommends replacing the filters every 6 months, but I usually use these a little longer as I clean them with my vacuum every couple of weeks to extend their life. Also, I wasn’t able to find filters for the 311i on the Blueair website as of this review, but based on their other similar air purifiers the filters are a bit pricey. Pros: -Simple operation -CADR rating of 150 -Sleek, aesthetically pleasing design -HEPASilent technology -Can operate quietly Cons: -May be too small for large rooms -Filters look like they may be pricey

Recieved this and the fan sounds weird on the highest setting. Got it on sale during Black Friday wanted to exchange it so I’d get it at the same sell price. They said they’d send another one it was supposed to be here yesterday. I checked status on line and they had canceled the order. Has spent and wasted a lot of time on mine texting and chatting with customer service to no avail. Will be returning this today and will have to wait for a new one. I’m supposing or I’ll get it elsewhere. Avoid Best Buy if at all possible the return policy and customer service is subpar. I feel like ive been herding cats trying to get a working purifier. They don’t care if you are put out because they are not.
