Want to organize your pantry and keep food from going stale? The Prepara Evak Airtight Glass Food Storage solution may be just the thing for you. I have been looking around for a durable airtight solution, but not necessarily to stave off stale food. My desire is to find a product that is truly airtight to prevent insect infestations. Many products have claimed to be airtight, but when tested, really are not. I cannot say for sure if this product is truly airtight, but it would be nice to check it out. The lid has air inlet and outlet valves. As you push down on the handle the air escapes through the outlet valve to remove the air over the top of your dry food. To remove the lid, all that is necessary is to pull up on the handle (no buttons or levers) which then allows air back into the jar through the inlet valve – no Herculean strength needed! It is made of glass, stainless steel, and has a silicone gasket. It is BPA free and dishwasher safe. There are two different sizes available: medium for $19.99 (3.75″ D x 3.75″ W x 6″ H, holds 1/2 lb of coffee | 24 oz | 3 cups | 0.75 qt | 709 ml); and large for $24.99 (3.75″ D x 3.75″ W x 9.825″ H, holds 1 lb of coffee | 46 oz | 5.75 cups | 1.4 qt | 1.36 l). They may be purchased from the Prepara website.
