The plus side of this purifier is that it looks nice and is compact enough to stay out of the way.... if you are looking for a useless and expensive piece of equipment that gathers dust. It worked for about 2 months, and we cleaned it and took good care of it. After two months the clean light came on and would not go off despite numerous attempts to thoroughly clean it and reset it. We thought it might just be a defective one, but after a little research we found that a lot of people have the same problem with this brand. The company was of no help either. Unfortunately we held onto it for too long (trying to fix it) that we couldn't return it. It was the biggest waste of money. I would not recommend it to anyone, nor would I recommend purchasing items from this company. I only gave it one star because I have to rate it with some value for the review to be created.
