I just received the Shark- Air Purifier 3-in1, and have to say the family is loving it. Not only does it purify the air, it has a fan for cooling the room. The main feature we use is the heat. We live in the Northern part of the Country and are having some cooler October mornings. I find my kids coming downstairs and turning this on to take the “chill” out of the air. We also love the heated purified air while we watch a movie. We just have it oscillate and heat or cool the room we are in. Very easy to set up and operate. The “puck” comes off the top and acts as a remote, though you will need to make sure to directly point it at the tower. Great product!
