We put this in my daughters room, she’s nine and we have two cats. She always seem to get allergies from the cats. Ever since we put the purifier in there she stopped completely with the allergies. The whole room smells and feels fresh. The purifier has a pretty specific smell of brand new. You can’t even smell the cat’s litter in the house. It’s blows cool air, heat plus it purifies.  It has different colors to identify the air quality. From blue, to orange to red. The best thing is that it has six speeds and is super quiet.
