OXO Good Grips GreenSaver is a complete food storage system that keeps your produce fresh longer and fits perfectly inside your fridge. Our enhanced carbon filter is filled with nooks and crannies that trap and absorb ethylene gas, slowing down spoilage and keeping fruits and vegetables fresh. The elevated colander keeps produce away from the container walls to promote 360° air circulation and prevent rotting. The adjustable vent optimizes humidity for different types of produce -- from delicate berries to leafy greens. Dishwasher safe and BPA-free, available in three convenient sizes designed to store all types of produce. Each GreenSaver comes with one enhanced carbon filter that lasts up to 90 days. Refills sold separately.
