(Refills packets only; no Bluapple containers are included in this kit.)The 3 vital factors for successful and longer produce storage are temperature (38-48 degrees at all times), humidity (moist but not wet environment), and ethylene gas control (using the Bluapple®). Disruption of any one of these factors will cause premature spoilage. Fruits and vegetables naturally produce ethylene gas, which has a profound effect on the freshness of produce. Once concentrated in your refrigerator or other storage areas, the presence of ethylene continues to speed up ripening and hasten spoilage.The average household throws away over $600 worth of produce per household each year due to accelerated spoilage from ethylene gas. The Bluapple is designed to provide effective ethylene gas absorption for three months in a typical home refrigerator produce bin or storage container. The Bluapple does not release any gas or chemical, but only absorbs, constantly removing harmful ethylene from your produce storage area, so your food cannot be harmed. The Bluapple is not "magic,” but a scientific and essential part of keeping produce fresh.Bluapple is refillable and works best in an enclosed space such as a refrigerator crisper, covered bowl, or paper bag. The active ingredient in Bluapple continues to absorb ethylene until it has reached its capacity. When it is time to replace the packet, open the used packet and add it to your houseplants or in your garden, as it makes a great fertilizer. Your plants will love it!In order to slow down ripening and spoilage, commercial warehouses, ships and trucks in the produce industry are nearly all fitted with ethylene absorption technology. Bluapple has been thoroughly tested to bring this same technology to your home, helping you to save you money and benefit the environment.Includes:Eight replacement ethylene gas absorbent packets, enough for two Bluapples® (not included) for a full year of protectionHandy chart to help you remember the Produceology™ of various produce varietiesFeatures:Replacement packets designed for BluapplesBluapples prolong freshness and storage life of fruits and vegetablesUtilizes the same technology used by the produce industryPut Bluapples in refrigerator crisper drawers or anywhere you keep fruitBluapples work best in a confined spaceEarth-friendly Bluapple is designed to be refilled and not added to landfillsBPA-freePays for itself dozens of times over in the first year aloneAverage household can save up to $600 per yearMade in the USA
