Title: I am not very satisfied with the unit
Review: This unit says up to 500 sq foot for clean air usage, I currently am using it in my office that is approx 200 sq ft and I am not a heavy smoker and it just doesn't quite do the job, I guess when I close the door, leave it running on high and come back into the room about an hour later (after having one or two cigarettes) the room smells clean but that is about the level of performance you should expect out of this unit. I would not recommend it.
