This container automatically creates a vacuum when you close its lid, providing oxygen-free food storage that preserves the freshness, flavor, and nutrients of food by up to three weeks. By removing all of the oxygen, the container inhibits microorganism growth and slows the oxidation of fruits, vegetables, bread, and pastries to a fraction of its natural pace. The device automatically maintains 16mbar (the optimal pressure for preserving foodstuffs) and reduces air moisture that can encourage mold growth. The lid opens by lifting the latch, providing easy access to food, and the unit automatically reseals once the lid is closed. The container is large enough to hold up to 16 apples and has a dial on top of the lid that allows you to mark the date food was first stored. About the size of a breadbox, the unit stores unobtrusively on a countertop or table. Interior tray removes and is dishwasher-safe. Plugs into AC or uses four D batteries (not included). 10" H x 19" W x 9" D. (7 1/2 lbs.)
