Product review (5 stars): Laundry area is in a half bath so we like to keep the door closed
Installing this unit in place of the traditional flap style greatly reduced the draft I was getting back through the dryer. Laundry area is in a half bath so we like to keep the door closed, with the traditional flap style the room became very cold. Since I have changed to this unit the bathroom stay s much warmer. Works great.
