The FilterWow Door Snake Draft Stopper is the perfect simple, cost effective and practical item to help you save money and keep your home at the temperature you want. Whether using it in the winter as a door draft blocker to block the cold air out, or in the summer to keep the cool air in, this product has your gaps and cracks covered. A straightforward design, it is a 36 inch long tube made of woven synthetic fleece cloth with a satin trim and filled with nylon fibers and cotton bags of ground stone beads for weight, similar to a beanbag or sandbag. It is machine or hand washable and has a woven satin loop handle on one end to hang around the doorknob when not in use or drying. It can be placed at the threshold of interior doors to help soundproof between rooms and hallways blocking and absorbing unwanted sounds from outside the room. It can also be placed on a windowsill as a wind block. Regardless of what season you choose to use it in, home insulation should help to keep your home warmer in the colder months and save on energy costs.
