I bought this product to clean the air because my husband has developed allergies. To what we don't know for sure, but starting in the home was the best idea to me. We removed all the carpets and had the duct work cleaned. It helped, but not enough. I chose this product because of the amenities and the reviews. It works wonders. I move it from room to room every other day and after I vacuum and dust. The dust on the furniture is less than 1/2 and there are no odors, even after cooking, it really cleans the air. We have a cat (husband doesn't react to the cat) and it even eliminates any litter box odors. It's quiet, unless you turn the fan on high. It monitors the air and the color of the light on the front lets you know what the quality is. It's light weight and the cord wraps at the back. I'm very happy with the purchase!
