    Best air cleaner I've purchased. It cleans the air and makes it easier to breathe. I'm an asthmatic and I can tell the difference in the quality of air I breathe.

    I liked this air purifier but because it had a chemical listed on California Proposition 65 that could cause cancer or problems with fertility I had to return it. I did not notice this problem because the warning was printed on the bottom of the box. There was never any warning Online next to the product. I have reactions to any chemicals list on Prop 65.

    It works great with cleaning the air at my house. The smell of fried foods no longer linger since I've purchased the air purifier. The only thing I dislike is how loud it is. I wish it was more quiet.
