I keep it in my bedroom where my 2 dogs sleep. You can't smell the dogs at all!  The other day I had to move it to the kitchen because something we cooked made the house smokey. The air purifier ran for 20 minutes at high and the smokiness was  completely gone. I'll have these in every room in my house before too long. I got the product I'm reviewing for free from the applicable brand in exchange for writing that review
