Go to StoreThis Refrigerator In-Line Water Filter removes contaminants from the refrigerator water supply. Compatible with many refrigerators with an automatic ice maker or water dispenser, we recommend that this Refrigerator Water Filter be replaced every 6 months to ensure clean, fresh-tasting drinking water. Replacing this part will require basic hand tools, some disassembly of the refrigerator and novice repair experience. Recommended Item: Copper Ice Maker Water Line Kit (item 8003RP). Includes 15' long 1/4" diameter copper tubing, drill type saddle valve, and all necessary hardware. A water filter can also be added inline with the copper supply line to improve the quality of your ice.
