This is a wonderful air purifier! We have been using it for a few weeks and I have noticed a big improvement in the air quality in my house. We have children & cats, so we are used to the smells, hair, and dust that comes along with life. Since I have been using this air purifier, the smells have gone down a lot and I've also noticed less dust & fur in the air. We sleep better as well. The frequency of allergy related issues have been greatly reduced. The sleek design fits in well with any decor and I love that it can be positioned either vertically or horizontally so fitting in with any room arrangement won't be a problem! It is also very quiet. On the low and medium settings you can hardly hear it. On the high setting it just sounds like a fan (a nice, white noise!)
