Waste less and save more with OXO GreenSaver. Three things cause produce to rot and spoil quickly: ethylene gas, improper airflow and uncontrolled humidity. The OXO GreenSaver system has the solution. GreenSaver Produce Keepers feature all-natural, non-toxic activated carbon filters filled with nooks and crannies that trap and absorb ethylene gas, slowing down spoilage and keeping fruits and vegetables fresh longer. They also have elevated, removable baskets that promote proper airflow and help prevent moisture build-up by lifting produce up and away from the bottom and sides of the container. These baskets can also be used as a colander to rinse fruits and veggies before enjoying. The vent on top of each Produce Keeper slides open and closed to maintain optimum humidity levels for different types of produce. These three factors work together to keep your produce fresh longer.PlasticHandwash recommendedLifetime guarantee on mechanism Shop At House Of Fraser
