Air takes out the freshness, EVAK Fresh Saver takes out the air! The longer your food is exposed to air, the faster it loses flavor. Plastic containers with air-tight lids are readily available, but they trap stale air in with your precious food. Evacuate the air and keep food fresher, longer with EVAK Super Savor BPA free plastic storage containers by Prepara. The twin valve system automatically forces the air out as you push down the lid and allows you to easily pull up and remove the lid for access. Lid acts as a plunger; hear the whoosh as the air is displaced! Our original Evak Fresh Saver container was tested against the leading brand of storage container and there was no comparison. The Evak Fresh Saver locked in flavors for longer and kept contents fresher. The new Evak Super Savor takes this concept to the next level by adding a second gasket to the mechanism. This provides a vacuum seal directly on the surface of your food! This is ideal for moist foods such as salsas, hummus, kimchi, guacamole, etc. In fact, due to the vacuum surface seal, our Evak Super Savors will actually keep your fresh guacamole green for days in the fridge! Still not convinced? Try one! We have a 5-year guarantee for satisfaction and quality. We are sure you'll love it. It's so simple- just push down, then pull up; no buttons or levers.
