Nice clean air .
I’m very happy with my air purifier, as the owner of a cat who sheds and loses a lot of dander it’s nice to know that the air in the room she and I sleep in is clean and fresh .I put it on automatic and don’t even hear when it comes on ,it’s very quiet .There is just one thing and nothing to do with the quality of the product ,I would have liked it in white as it’s in my bedroom.Since I’ve had it I’ve noticedt my sinus problems have been a lot better.It’s a great product.
