This in-line water filter is designed to connect to your ice maker and/or refrigerator. The 2-ends of the filter have a 1/4 in. compression connection that installs easily on the water supply line that goes from a water valve to your appliance. This water filter is designed to improve the overall taste of water and to remove odors. It has a greater capacity than traditional water filters that are installed in the refrigerator or ice maker.
