Product review (5 stars): Best dryer vent closure we have had
Best dryer vent closure we have had. Doesn't clog. Keeps moisture out which is really critical in our very humid climate. My old dryer vent closer (which had a hinged door underneath a louvered cover) eventually stopped completely closing due to corrosion of the metal and years of lint buildup. If clothes were left in the dryer over night, they would be damp again by morning! Not only does moisture not come in overnight, it doesn't permeate at all, meaning the clothes get dried more efficiently and less energy is used. Make sure when you install it to also take the opportunity to clean your vent hose and ensure it's not too long. Guidelines for vent hoses can be found online and will help you get the most benefit from the Heartland 21000.
