I purchased two of these. One for my daughter’s room and one for mine. My biggest concern was the mildew smell in my bedroom and this purifier instantly cleared it up!! I had purchased one for my daughter because she was getting all sorts of different viruses from school and I just wanted to put in another safe measure. This purifier has not disappointed. They are aesthetically pleasing and the perfect size for a bedroom. I have been referring to friends and family. Highly recommend.
