OXO GreenSaver Carbon Filter Refills - 4 Pack V1

Each filter lasts 90 days, giving you a year of freshness from a 4 pack, and can be used with any GreenSaver product. Fruits and vegetables naturally emit ethylene gas, which causes premature spoilage. GreenSaver’s non-toxic, enhanced carbon filters help keep produce fresh longer by absorbing ethylene gas.
