ADAPTER GE SmartWater Filter Adapter
Our customers tell us this GE filter adapter can be tough to find, so we always keep a healthy supply in stock. If your fridge uses one of those old GE or Culligan filters with a silver metal housing, this adapter will let you upgrade to the GE MWF Filter which is better and cheaper. Best of all... the adapter is designed to be reused so you'll never have to buy another one!
