Not sure if this matter to you, I just install a Sam Sung unit for a client's bedrooms on the upper floor. this has a photo insert and it looks like a picture frame instead of that big-o-square box of a blower. Its a few bucks more, but a lot better looking and quiet too. Three blowers for two small bedrooms and their study. A single one can be had I suppose?
