      • A great budget purifier with AUTO feature!
    Style: 411 Auto
    Having an AQI sensor with an auto mode is pretty rare for purifiers at this price range. BlueAir is really cool for creating something inexpensive to be a set it and forget. I’ve tested and tried many different air purifiers and while I have a favorite already, this one really deserves its praises. For starters, I want to say this is definitely a bedroom-centric purifier and isn’t meant for larger open concept spaces (Opt for the 311 Auto for bigger area). The 411 auto is virtually silent on level 1. Level 2 is also pretty quiet but has a very gentle breeze sound (personally my fav for sleeping bc the white noise is calming). Level 3 definitely is a jump in sound but is good for brief quick air cleaning. Auto mode is pretty accurate with detection rate. I put out a candle that was relatively close proximity to the purifier and the sensor light turned red and gradually revved up to sift out the smoke. In another test, I blew out a candle that was further away from the purifier across the room. The sensor did take longer to begin revving up the fan (about 5 mins give or take) but nonetheless still managed to detect. I find dissipation of odors and smoke to be pretty decent. Today I was indecisive about outfits and tried on many diff things while looking in the mirror and I guess all the dust and lint kicked up and got the little guy revving up. All this to say, the AQI sensor and Auto Mode is great! Other positives: -low power consumption. It’s gonna be so inexpensive on your electricity bill. Only 10watts of power max! -stylish! The prefilters are very attractive I’m in a very modern minimalist space with black and whites and grays. The default pre filter it ships with fits perfectly! Diff decor? They have many different colors for you. I have to say, I doubted this thing for a bit because of its seemingly lacking power. It reminded me a lot of the Levoit Vista 200. However that model is awfully weak and not worth the money. I believe the reason why the Blue Pure 411 Auto works so efficiently well, is because it is 90% filter. There’s no plastic unibody or restrictive intake grills. Just fabric and filter. Because of this, less fan power is needed to pull in air through several layers of plastic holes and super dense materials. Pretty innovative and a true example of “less is more”. Highly recommend for those who want a stylish, efficient minimalist air purifier for a small space. ... show more

      • Easy Breathing & Clean Air
    Style: 511
    Unit was slightly larger than expected, but still small enough to be discrete. Attractive design. Basic, no frills model that does a terrific job. It is completely silent on lowest and very quiet on higher fan speeds. No annoying light stays on to show the unit is operating. It does an excellent job in our primary bedroom. Highly recommend. ... show more

      • It simply works, and it’s fantastic
    Style: Mini Max
    I never thought I’d need one of these, but my son has been getting stuffy at night for these past few months and it disrupts his sleep. This air purifier started working pretty much immediately. Even I didn’t realize how bad my allergies were til we started using this, and I breathe so much easier now. It has a “night mode” which just means the fan is lower and quieter, but we sleep with a fan anyway and like the noise. So we turn it all the way up for max effect during the night and just leave it running on the low setting during the day. We got the mini as our rooms are on the smaller side and it works exactly as I’d hoped it would. It’s also a nicely sized and cute machine. There are different color fabrics you can put over the outside which I plan on getting later on. It’s extremely simple to use and so lightweight I was actually worried about the quality, but it works so well and is totally worth the price point. Zero complaints about this machine. Will buy this one again if the need ever arises. ... show more

      • Decent air purifier … so far so good
    Style: Mini Max
    So far I’ve purchased two mini max units and they seem to be working fine. One in the bedroom and one in the living area. I’ll check the filter that came in the unit, but product description says it comes with one temporary filter in unit and one extra filter, and there was no extra filter in either box, only the filters that came in the unit. I contacted the supplier via chat message and they say that the filters that came in the unit should last about 6 months. So i went ahead and ordered four extra filters which run about $9 each. I do like the size of the units and they are quiet. Also the price is good as compared to many others. Otherwise, my cat isn’t sneezing like she used to. And I feel they are working as expected. ... show more

      • Quiet and Effective Air Purifier for Any Small Space
    Style: 511
    The Blueair Blue Pure 511 air purifier has been a fantastic addition to my home. It’s compact, sleek, and fits perfectly in a bedroom, nursery, or small living area. The design is modern yet simple, making it easy to blend into any space. Setup was straightforward—plug it in, and it’s ready to go. This purifier’s standout feature is its HEPASilent Technology, which combines electrostatic and mechanical filtration for top-notch performance. It captures dust, allergens, and even pet dander without making a sound. I noticed a difference in air quality within hours—my room feels fresher, and my allergies have significantly improved. Another big plus is how whisper-quiet it is, even on higher settings. It’s perfect for nurseries or bedrooms where noise can be an issue. The energy efficiency is impressive too, so you can leave it running without worrying about your electricity bill. Maintenance is simple, with a quick filter change every few months. If I had to nitpick, I’d say it would be nice to have a built-in air quality sensor, but for the price and performance, this purifier is excellent. Whether you need relief from allergies or just want cleaner air, the Blue Pure 511 is a must-have! ... show more

      • It works as advertised!
    Style: 411 Auto
    I purchased the 411 auto several years ago after the first huge Northern California fires, and I love it. I have dust and pollen allergies that challenge my immune system year-round, and smoke just adds to my misery. This machine keeps my bedroom a safe haven. It's easy to clean, energy efficient, quiet, and even helps keep my bedroom clean. ... show more

      • Works well to clear the air. Highest setting makes a nice white noise.
    Style: Mini Max
    If you like quiet use first setting or if you like a little white noise use the third. It does a great job of clearing the air. I've had it a few months running several hours a day and had no issues. I have a cat and I can tell a difference in allergies.
