Blueair - Blue Pure 311 Auto 388 Sq. Ft. HEPASilent Air Purifier - White

Great buy! We purchased two units and felt it to be pricey but it’s giving us peace of mind. The units are quiet at all levels. Really enjoy having them.

I've been using this for the past few days and can already feel a big difference. My allergies had really been acting up over the past few weeks, especially early in the morning when I wake up. I placed the air purifier near my bed and let it run throughout the day. It is relatively quiet, really just a whisper of the motor running. After using it for three days, my sinuses aren't as stuffy in the morning and throat isn't sore either. The purifier has 5 settings, though I have only used the main run setting and night mode so far. Although it is relatively quiet, in a quiet room at night it woke me up when it started up, so that is when I put it in night mode. There is also a sensor for how clean the input air is. The air in the bedroom in now clean (blue), but I didn't notice what the color was when I first turned it on. I haven't had to replace the filter yet (roughly 6 months according to the documentation), but Blueair has a subscription service where they will automatically send you replacements (~$34). Buying the replacement filters from their site when needed will cost you about $40. Overall, I would recommend this air purifier. It seems to have made a difference with my allergies.

Designed in Sweden, under the Unilever umbrella of brands, the Blueair 'Blue Pure 311 Auto' Air Purifier is a simple, honest, no frills air purifier that does exactly what it says it will do, and does it well. A simple plug and play, very minimalist unit, very in keeping with Swedish Style, all you have to do is plug it in and press the button on top. This sets it into auto mode, and it will kick into life, very quietly indeed. The sensors inside monitor the air quality and adjust the fan speed as necessary to clean the air in the a room up to 388 sqft. Designed for medium sized rooms, with a sleek grey outer filter (that is interchangeable with other colored filters available from Blueair), protects the main 2 stage HEPA filter from large particle debris, such as pet dander, hair and dust. The particle and carbon filter is effective against Pollen, Pet Dander, Dust, Bacteria and Viruses, VOCs (paint fumes etc), Chemicals, Smoke (cigarette), Dust Mites, Mold and Cooking Odors. The HEPASilent filter system ensures that you get the maximum air quality in the shortest time, with minimum noise. In my experience, the sensors are sensitive, and they do react to changes in the air almost instantly. I have it set up in my master bedroom, and even walking past it, you can hear it kicking into medium speed, to counteract the stirring of the air and any particulate that may come through, in most cases it's freshly sprayed deodorant from myself or perfume from my wife. It kicks into high gear when the air quality is deemed too poor, and a red indicator lights up on the front. It works quickly and efficiently and helps get the air quality back to acceptable levels without fuss. I've noticed a marked difference in the air quality in the master bedroom, especially overnight, when you can get that 'sleepy air' odor. That has all but disappeared now, which is very nice indeed. You can bypass the auto setting by pressing the button on the top and choose night, medium or high, or off. The night mode maintains the lowest setting, and turns off all LED illumination for uninterrupted sleep. I do wish this feature was included in the 'auto' setting, so that it would automatically set to night mode, at a predetermined time. That would save having to adjust it every night before going to bed. This air purifier is NOT app enabled either, so you can't schedule it to come on and off at certain times. That would be a nice feature, or to be able to control it via Alexa or Google via voice would be a welcome addition. Overall tho, this is a simple and very easy to use unit, that is really silent in it's low mode, and only kicks it up a notch when the sensors detect a change in the air quality, ramping up the fan speed. You can purchase different colored outer filters to match your decor online on the manufacturers website, and also sign up for a filter replacement program that will ship out new filters before the current ones expire, should you so choose to.

The BlueAir Pure 311 is a great little machine. As someone who suffers from many airborne allergens, I was excited to see how an air purifier would work for my situation. I'll first remark about how "clean" and modern this machine looks. Mine has a nice grey fabric bottom with a white plastic upper piece. This fits the decor of my house very well and I imagine many others as well. Setup is as simply as just plugging it it and pressing the "on" button. Thats it. Pressing the "on" button multiple times puts this in various modes. Press once for "on" mode and the fan sill auto adjust itself based on air conditions. Press twice for night mode: this is the mode I have it on most of the time. It turns off the LED on the front as well as turns the fan low so it runs pretty quite. This is a great feature to aid in sleeping. Press three times for "every day mode" which is medium fan speed. Press four times for "boost mode" which cranks the fan up to high speed and helps eliminate poor air quality situations faster. My unit has always detected good air quality so I cannot comment on how much better the air really is as I have no way to measure otherwise. I can state that I feel like I sneeze less at night and tend to sleep through the night, which is not something I've always been able to claim before I started using this machine. My bedroom is about 400 sq feet and I keep all closet, bathroom and hallway doors closed while this is running. I tend to keep doors open during the day so I do not run this during that time, it is reserved for night time only. Overall since I am sleeping better and this offers no annoyances at night, I cannot think of a reason not to like or recommend this unit. It's simple to operate and thoughtfully designed.

The Blueair Blue Pure 311 Auto is probably one of the finest air purifiers you can get. Beautifully designed, very simple to use with its one-touch button, and yet so easy to maintain. You unpack it from the box, there’s nothing to assemble, just plug it in, touch on the top button once, and the air purifier turns in in auto mode. It then takes 30 seconds for the purifier to determine the air quality, i.e., how much air cleaning is needed, and then settles on the right fan speed (low, medium, boost). There is also a visual confirmation through the front “air quality indicator” LED: Blue means good air quality, orange means moderate air quality, and red means polluted air. Now, one of the reasons why I wanted an air purifier was to ensure I get to breathe perfectly cleaned air in my master bedroom. The good news is, when you select the “Night Mode” by pressing the top button twice, it selects the low fan speed and leaving all indicator and air quality lights off. No light pollution whatsoever. Awesome! - Not so good news: Though I knew there would be some noise from the low-speed fan, I was surprised about hearing different hums in various frequencies to the degree I wouldn’t want the air purifier turned on anymore. However, I had another need where this air purifier is doing a fantastic job: My home office! It is a smaller room in my house where I spend lots of time due to the current pandemic, filled with lots of electronic gadgets: From laptops to desktops to printers to networking stuff (Ethernet switches, routers), where most of them run their own fans. I feel with the Blueair Blue Pure 311 Auto air purifier that I now run day in and day out in auto mode the air quality in my office has greatly improved. Much less coughing than before! For this reason alone, I am giving this air purifier 5 stars. And, if I could, I’d give another 5 stars for the design. It’s a beautiful air purifier that harmonizes beautifully with its surroundings. P.S. The Blueair Blue Pure 311 Auto comes with two filters that need regular maintenance: (1) The fabric pre-filter which you can clean simply by vacuuming the exterior with a soft brush attachment, and (2) the Main Filter which you need to replace with a new one when the indicator light on the top button glows red.

Amazing product. Me and my kids can breath better A

I live in south Texas and its cedar season. I was very excited to receive this product because I currently don’t own an air purifier and this season cedar has really been bad on me. I can walk outside and I typically get hit with it immediately. So, I was hoping this would do something to help with my allergies and with any potential cedar pollen in the air. The design is fantastic and practical. I like the round cylinder shape because it really gives you more options with placement. I chose to put this in my master bedroom, mainly because its where I spend a lot of time (sleeping) and at night when I lay down, I typically get congested and stuffy. We have our ceiling fan on high all the time so its constantly moving air around. I placed it in a corner away from the wall and it seems to be doing great there. It came ready to rock and roll in the package. I literally opened the package, peeled off a sticker on top of the power button, plugged it in, and turned it on. There was NO setup whatsoever. Plug and play which is very convenient. I also like the fact that the outermost pre-filter that wraps around the HEPA filter is replaceable and they offer many different colors to choose from. They state the filter has approximately 6-month life spans and it is very easy to replace. The 6 months is perfect because it falls in line with my whole house air filter on my AC unit. The air quality indicator I feel is pretty accurate. We will see it change from time to time and it seems to change when my wife vacuums the carpet in the master bedroom as well. The results of using this in my master bedroom were pretty much what I expected. I sleep very well and I am much less congested and stuffy at night. I will be purchasing another one of these units for my living room. I feel like one in the master and one in the living room would really make a difference in my home. I am very glad I got this air purifier and I highly recommend anyone in the market for one to check this one out especially because of the design, ease of use, and effectiveness.

One of the things we are particularly cautious about these days is our air quality. Even though most air purifiers can’t protect against pandemic-level viruses, it’s good to include them in your home to help with air circulation and the filtering of other dangerous chemicals that seep into the air. The Blue Pure 311 is a great option for homes because its easy operation and low maintenance. The purifier arrived in its retail box, which doesn’t have a lot flair to it. It’s a simple cardboard box with blue printing on it. The details are highlighted on the box. The retail box was nested inside of a larger shipping box that also had some identifying information on it - like an outline drawing of the purifier. The purifier has its power cord permanently attached to the unit. The wall plug is quite large and will require being plugged directly into the wall or possibly across two outlets on a power strip. Setting up the purifier is very easy. It’s ready to go right out of the box. This is a refreshing change to other purifiers that I’ve worked with that require filter installation or app set up. You take the purifier out of the packaging, plug it into power, and then tap the top of the unit to select the mode you want it to work with. I chose AUTO and just tapped the control panel once to activate it. I have to admit that it would be really nice if this were a ‘connected’ purifier so that I could see exactly what its sensors detect in the air, but that would eliminate some of the simplicity of its functionality. There is an indicator light on the front of the unit that changes colors when impurities in the air are detected. When the air is clean, the purifier’s light shines blue. It’s a very quick visual that tells you immediately if there is a problem with your environment. There is a user manual included with the unit and it has suggestions for best performance for the purifier. In order to ensure that it can clean all the air in a given space, the purifier needs room to ‘breathe’ and shouldn’t be placed any closer than 4 inches to any given object. This can present a little bit of a problem if you are trying to hide the unit in a room. You can’t just stick it into a corner and hope it’s going to do its best work. It also suggested that you keep the room closed off while the purifier is in operation. This presents a different problem, too. If your home is anything like mine, the larger spaces are open to other parts of the house. For example, our living room has open doorways to our hallway and dining room/kitchen. Ideally, this purifier would be in the living room since it’s one of the larger rooms in the house. But for testing, I pulled it into a smaller room that didn’t exceed the size limitations of the purifier (no more than 388 sqft) and could be closed off per the user manual’s suggestion. In this smaller bedroom, I also happen to have a air quality monitor. This room is approximately 100 sqft in size and is used primarily as an office space. My fiancé uses it to work from home as well as personal projects. She has noted that the air quality monitor that’s in the room tends to alert her to rising CO2 levels after working in the room for a couple of hours. We hoped that maybe by placing the purifier in that room that the CO2 levels would decrease with continued use. When we first plugged in the purifier and turned it on AUTO, the unit took about 60 seconds to fully boot up. When it did, the sensor detected that the air wasn’t as clean as it could be and the fans kicked onto a moderate level. Noise-wise, it’s about what someone would expect from a purifier trying to actively clean the air. After just a few minutes, the fan speed/noise decreased and the indicator light turned blue. The specs on the unit indicate that it takes approximately 12 minutes to fully cycle the air in a larger room and I noticed that after less than 10 minutes the purifier had gone to a lower fan setting and the air quality had changed (according to the indicator on the purifier). As for the other air quality sensor in the room, its readings indicated that there were still higher levels of CO2 and other air particulates in the room, but its app indicated that overall levels had decreased after an hour of monitoring it. I’ve been fortunate to work with this brand of air purifier before and I absolutely love how easy it is to work with. Sure, I would love to have advanced monitoring options available for it, but it does a great job and I can recommend it for homes and offices.
