Product review (4 stars): Keeping out the cold!
The best way to know if this works is during a cold blast so comparing this to a flapper vent .........this is much better. I have two apartment units. One with this vent and the other with the old standard flapper vent. The laundry area with the flapper vent is cold and you can feel the draft coming in from the flapper vent. This vent shown helps to keep the vent noise down and helps to avoid the wind from just blowing inside the dryer. The top doesnt come off, the air comes out from the bottom of the vent.....sort of like an upsidedown cup. It helps to keep the chill to a minimum so I am planning on changing out the flapper vent to this and save money!! This arctic blast in the midwest is going to cost money!
