I really like this air purifier but I've only had it a couple of months and it's become temperamental and won't actually start everytime I turn it on. I have to turn it off and on a few times to get it running. When it does work I do feel like it's making a difference to the air quality.
Noise wise its not super loud it's like having a fan running.
I'm just not sure how long it's going to last for which is a little disappointing but hopefully it keeps ticking!
