How They Work

Once the bag is loaded, again permitting a two-three inch gap, and the bag is closed, the user connects the household vacuum hose to the air valve and draws all the air from inside the bag.
The air-tight seal protects the goods from water or other moisture related conditions. The process is safe and healthy.
