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!

### ⭐⭐⭐⭐⭐ Works great with no problems
*by A***R on January 26, 2026*

We have had this machine since around 2020 and it works great. I replace the inner filters every 6 months. The outer cover helps make the filter last longer. It had various speeds and noise levels. Overall I would say it’s quiet. It helps reduce dust accumulation, smells and allergies. It is very lightweight and portable, it has been a great value and is still running great five years later. My only complaint is that I have to reset the filter notification. Sometimes it takes me a bit a couple of attempts to reset the notification lights.
