I have 3 air purifiers in my house and this is the best of them. I keep this in the living room near the kitchen and it works silently. Plus the fragrance diffuser smells good. Some features that I like, it runs on eco mode, fragrance diffuser, silent running and indicators for air quality on the front. This air purifier is very light so easy to move around if you need it. Amazing product. This is my second Shark Product and yet to be disappointed,
