Keep produce fresher longer with this Rubbermaid FreshWorks Produce Saver 3 Piece Set. Revolutionary FreshVent technology creates an optimal environment for fruits and vegetables by regulating the flow of oxygen and carbon dioxide in and out of the produce container. The CrispTray at the bottom of the food container elevates produce away from moisture and promotes airflow to help prevent spoilage. The built in lid filter never needs to be replaced and will last a lifetime. Use the medium food storage container for strawberries or sliced fruit and the large storage containers for heads of lettuce or whole veggies. Longer lasting produce means fewer trips to the grocery store.
