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: It's new, working, silent, looks good, and I feel like I'm breathing better. - Simple to set up. Works fine. I've only had it for a few days and will put up another review after I have changed the filter in about five months. I'll be able to see the dirty filter and know how well it keeps my room dust free. The air here many times is loaded with dust from the desert winds when they really pick up.

### ⭐⭐⭐⭐⭐ I'm REALLY impressed with this
*by T***S on November 20, 2025*

This Blueair air purifier is pretty amazing. I should preface by saying my husband and I are both indoor vape users. I was worried an air purifier wouldnt be effective because of this fact. Add in that we have two large dogs and 4 indoor cats. - Blueair proved me wrong. So I bought this unit in May 2025. It's now the 20th of November and the filter JUST turned red promoting me to replace it!!! Holy cow! That's an amazing value and effectiveness!! It made a huge difference this entire time with lowering the smell of dog and indoor air pollution I could constantly smell in this home of ours. We have an older home with fixed windows, add in the 4 indoor cats and the inability to leave the doors open to let in fresh air regularly thanks to the constant Florida heat and humidity, and I was always feeling like the air was just stale and gross in here, even before the vaping came into account. But this air purifier has been a game changer. It was so easy to set up, so easy to maintain and clean (both regular maintenance and with washing the exterior cloth filter) and replacing the interior filter took no time at all. Highly recommended product!!
