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.

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.

In 2023, I purchased this device for my bedroom and it functioned satisfactorily. However, two years later, the power button has ceased to operate. I contacted customer service, who advised me to perform troubleshooting, which proved ineffective. Subsequently, I was informed that the device lacks a warranty, necessitating either replacement or repair at a third-party shop. I am perplexed by the necessity of seeking repair services elsewhere when you the manufacturer, especially considering the potential for future purchases. This experience has eroded my trust in the brand’s reliability, which is concerning given the quality of other products they offer. The customer service representative offered me a mere 20% discount or 10% if the device is currently on sale. Having owned two blue air purifiers in the past, this incident has prompted me to reconsider my loyalty to this brand. I am now seeking a more reliable alternative.

This air purifier is read to use out of box - no configuration needed, just plug it to the outlet, power on and select mode to use. Devices has 4 modes (press once for auto mode, twice to night mode, three times to everyday mode which is medium speed and four times to boost high speed mode – fifth press will turn device off). Fan has 3 speeds and device is very quiet which makes it perfect for bedroom use. We use ours in the kid’s bedroom which seem to feel fresher than before. Very good design and great size of the unit, and since is really light weight it could be easily moved anywhere. Side LED indicator will change color from blue, orange or red to inform you on air quality. Fabric pre-filter is washable, filter is not they need to be replaced. Light indicator on the top will turn red when time to replace/clean filter. Good for rooms up to 190sq ft. Energy officiant, uses less energy than one LED bulb. Simple as it could and should be. Pros: Ready to use out of box Very quiet Easy to use Washable filter Energy officiant Cons: None so far

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.
