  • 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

  • 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

  • Difficult to understand use, no clear on and off
Style: 511
I like the effectiveness of this air purifier so as far as performance goes, I think it should have five stars. Since there’s no way of testing air quality and we just have to go on faith, I’m guessing that it’s a good quality machine. However, clearly it was designed with aesthetics in mind and not practicality. It’s difficult to turn on an off or to know how to turn it higher or lower. You do this with a series of taps on the top ring. It’s very Star Trek in a very unnecessary way. I love Star Trek. I love everything about Star Trek. I don’t think even they would’ve kept this on the enterprise because it’s too annoying to use , however, having said that I just turned mine on low and keep it on all the time. I have noticed that environmental allergies bother me much less this year. If you are into the super modern look and have the gray walls that all designers think everyone should have now, you might love this look and usage facility might not bother you. I don’t think an older person would be able to use this easily. The only thing that lets you know if it’s on or off is a light that shines for a moment when you tap it. There is delay in the action so you don’t know if you’ve actually turned it up higher or turned it off for a few seconds, so if you’re impatient like me and tap it again, you’ll probably accidentally turn it off and have to start all over again . Again, weird design, leaving you confused. Is very silent and that’s a big plus. It probably deserves one more star, but I’m too annoyed with the lack of the on and off clarity to increase my stars. Here’s an idea, how about somebody make a vintage looking air purifier with simple on off switches, make it look like a vintage radio. I bet that would be a big seller, the nice old-fashioned knobs. On and off. I have no idea how I’m going to change the filter when it’s time to change it, the whole thing is a mystery as to how it’s assembled, and I wish they would just include a few extra filters with the purchase so then you weren’t trying to figure out what kind of machine you have and which kind of filters to buy six months later. I’d be willing to pay extra to have the extra filters delivered with the purchase. If I sound annoyed it’s because I am. But I’m sure the machine is good quality. Updated review 9/11/24: The machine is actually silent on low. It’s been on all day and I didn’t even know it. You literally cannot hear it at all on its lowest setting. It also did a great job getting rid of a smell that was from something burned in my kitchen. So it is a very effective machine. I also now am wondering if the thing that I found fault with is actually a benefit to older people with arthritis if they cannot turn a knob, then just tapping the top might be very helpful to them. In fact, anyone with mobility issues could put this beside their bed and just tap it at night in the dark and it would be easy to use for them. Because it is silent, it will not work for you as a white noise machine. I’m now going to add a star. Xo ... 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

  • A burst of fresh air!
Style: Mini Max
I love this machine and take it with me around the house. At night, it’s in my room. During the day, in my office. Setting number 1 is so quiet that I absolutely cannot hear it. I can hear number 3, but it’s still low enough that I can have it in the background during Teams meetings and it’s not at all a problem. One of my favorite things about this device is when I leave the room for a little while, then come back. I love that walking into the room with the purified air feels like stepping outside into the woods. The air just smells so good! In fact, it’s so good that in the morning, the air in my room is not at all stuffy. It’s light weight and super easy to carry. So, I actually take it into the office sometimes. When I do, my colleagues love meeting in my office because they like the way the air feels and smells. It’s also very pretty to look at. I love this thing! ... show more
