Have you ever noticed your clothes dryer feels cold in the winter and warm in the summer? If so, your dryer’s vent pipe is likely not sealing properly, and you are wasting energy as outside air leaks into your home. To prevent this, you should consider installing a new style dryer vent closure.
These easy-to-install vents allow your dryer’s hot air exhaust to escape when the dryer is operating, and uses gravity to seal it tight to keep outside air from leaking into your home when the dryer is not operating. The way this vent closure works is that inside the cylinder part, there is a plastic cup-like apparatus that rises when hot air is flowing out of your dryer. And then when the flow of hot air stops, the cup floats back creating a nice seal which prevents outside air infiltration. And further, it tightly blocks the path for insects or pests which might try to crawl in.
