Wow,this is a great product. Very easy to set up and use. I have a dachshund and his dander is alot. I also have asthma. This cleans the air so well that I don't have to use my inhaler at all do far. I can't believe it clears the air so well.it works great in my tv room and my bedroom. Filters out allergens and dander etc.. the touch screen led panel is easy to use. Best product I've tried so far. A,real health care product.
