    • 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

    • Works Surprisingly Well
Style: Mini Max
We put this in a guest bathroom where we keep a cat litter box. This helps a lot to minimize any smell. It is a relatively small size, so we keep it on the counter in the bathroom. Very simple design. We found that the adjustment buttons from the fan speeds were a little bit finicky. However, we don’t plan on changing the speed very often so we just set it on 2 and leave it there. It is not too loud. More like a white noise background machine. ... show more

    • Good for the size, quiet, instructions aren't helpful though if you can find them
Style: Mini Max
This air purifier is quiet and doesn't take up a lot of room. Small but powerful. Setting one is great for sleeping. I love that the outer filter is washable. It seems like the inner filter lasts a long time, too. After having this maybe 3 months the HEPA filter still looked really white and seemed there was no dust on it at all, and I was running it all night every night (on setting one). Now I use it in my office at my new place and run it all day on setting two. Not sure how long the filter will last on 2, but the replacement filters are not too expensive. The company is in Sweden and apparently there is no way to contact them. They say "Contact your local retailer for questions" which is basically Amazon! I bought the mini air purifier and it came without instructions, or maybe I lost them. Because somehow I knew there was a child lock system. I tapped on the fan icon and the fan setting wouldn't change. I held it down and it didn't change. Sometimes it turned off. Apparently there is some kind of child lock on it. I tried holding the on/off button for 5 seconds to unlock it and at some point I accidentally turned it up from fan setting one to setting two (which I was happy about, because one wasn't doing enough). Later I somehow accidentally turned the child lock off, I guess, because I was miraculously and thankfully able to easily change the setting from 1, 2, or 3 and back again. I just hope I don't lock it again. Between this and my washing machine lock getting stuck this month I'm fed up with the child locks! Make some items or optional models for people without kids at home! Or at least make it easier to turn the child lock off or post some actual instructions on the website. ... 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

    • Perfect and quiet!
Style: Mini Max
I have tried a few different air purifiers but never loved them. I got this one because it is small, quiet, and looks nice. The others that claim that they're quiet never actually are. They're usually bigger than pictured, and they just don't look nice. This one you barely can hear at the low setting unless you're extremely close to it! It's nice, not bulky, made well, and quiet! Highly recommend! ... show more

    • Love blue air purifiers
Style: 511
We have two in the house right now and they work so well. I felt a difference in the air after it ran for 30 minutes. We keep one in my son's room because he has a guinea pig and I hardly every smell the cage.
