Love it, just wish I would've gotten a bit larger ones. Got 2 of them for up too 700sq feet each but wish I would've gotten at least the 900 sq foot. Still have some dust but a lot less than we had prior. Also, we have 6 cats and these help so much. I Definitely recommend Alen air purifiers!

Beautiful air purifier! Works extremely well and can be SO quiet on lower 2 modes. The air physically feels cleaner if that makes any sense… Have this above my two litter boxes and the locations of the vents are really convenient. Does not have an automatic sensor but find that it really doesn't matter for day to day use! Tiny bit pricey but will wait for sales!!!

So much more better than Dyson. Im prone to getting respiratory infections. I can feel that the ALEN brand works because I don't get allergy attacks or wake up with irritated eyes hence, I'm able to sleep longer. I had my ALEN for about a month and so far so good it's been going strong. The sound it emits doesn't bother me. It actually puts me to sleep. If you're thinking about purchasing one, don't hesitate— you will notice the difference!
