The Shark Air purifier has a sleek contemporaty design that blends well with your style, without being annoying. It oscallated half turn so it does not heat the wall  . It is easy to set up, basically plug up and the buttons are self-explanatory, I like the fact that it heats and cleans the air of my choosing. It is great in my home, I use it down-stairs in the basement where we spend most of our time with our pets. it definitely makes breathing better. I really love the Shark Air Purifier 3-in-1 True Hepa filter
