I got this a few weeks ago and set it up right away in my family room. It is about 2.5 feet tall and needs to be 3 inches away from the wall. It was very easy to set up and turn on. It displays a percentage of clean air right on the side of it. There is a place for an odor circle that can be replacement. The one that came with it does smell really good. You can change the intensity as well! Highly recommend this product! It does a great job!
