This is a Brand New Refrigerator Replacement Water Filter. It replaces GE / General Electric part #s WR97X215, WR97X215A, & WR97X215R. This filter is designed to remove tast and odor from your refrigerator water. It is 6 3/8" long and 1 5/8" in diameter and connects with a 1/4" compression fitting on either end. If your filter is 10" x 2 1/4" inch, then you can buy the same filter in that size by searching our store for "Water Filter 172". Your water filter should be changed every 12 months. Thanks for looking and good luck!
