Review: Blueair is hands down the best. - Put this next to any other air purifier around the same size and price, no contest. I just returned a LeVoit I bought for the same price. Boy was that dumb. Louder than hell, super weak air flow, and smelled like toxic plastics. It was absolute CRAP. This Blueair is very quiet, has amazing air flow, smells like clean air, and looks SO much classier to boot (Scandinavian styling). I have another bigger Blueair in my office. It's been going for years (+ filter changes). Still works perfectly. Sometimes you get what you pay for. But other times, even when you pay the same, you don't. So shop smart. There's a reason good brands are good and cheaper ones aren't!!
Review: Actually quiet and works wonders! - I’ve been looking for a solid air purifier that wouldn't break the bank, and after seeing this one for around $100, I decided to give it a shot. Honestly, it’s one of the best purchases I’ve made for my home recently. What I Love: Whisper Quiet: This was the dealbreaker for me. On the lowest setting (sleep mode), I can barely hear it at all. Even on the medium setting, it’s just a very gentle white noise that doesn't interfere with the TV or sleep. Noticeable Air Quality: I have a dog that sheds quite a bit, and within two days, the "stale" pet smell in my living room was completely gone. The air just feels... crisper. Sleek Design: It’s compact enough to sit in a corner without being an eyesore, and the controls are super intuitive. The Verdict: If you’re looking for something effective without spending $400 on a high-end brand name, this is the sweet spot. It does exactly what it promises and stays quiet while doing it. Definitely worth the $100 investment if you have allergies or pets!

### ⭐⭐⭐⭐ Difficult to understand use, no clear on and off
*by M***E on September 10, 2024*

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
