Some types of vacuum sealing machines are the FoodSaver vacuum sealing kit and the Waring Pro Pistol vacuum sealer. Another type is the Nesco vacuum sealer.
The FoodSaver model vacuum sealer features a hands-free one-touch button that seals food. It also takes up little counter space. As of 2015, it is one of the most expensive vacuum sealers on the market. The Waring Pro Pistol uses its own bags and cannot seal any others; however, users can clean the bags in the dishwasher. The Nesco sealer is a lower-cost option, but some people report that air gets into the bags.
