My Comment: 23 x 20 x 11; 70W; 33 lbs. This air purifier has a remote control, which I find to be a very handy feature. The smells in the air, as well as the condition of it, is actually reported on the screen of this purifier. Most people don't leave their air purifiers on all day long, which is why the timer on this is extremely useful. I thought the 10 year warranty on this model was an excellent selling point as well. Not many home air purifiers offer that long of a warranty for their products.2
