Take an important step toward a healthy lifestyle with the FiltersFast FF21130. This efficient filter fits many French-door bottom freezer refrigerator models. It uses carbon block technology to reduce the taste and odor of chlorine, improving the clarity of your water and removing sediment. Replace your filter every 200 gallons or 6 months to maintain efficiency and performance. Enjoy the health benefits of fresh, purified water in your own home!

Note: The RPWFE is backward compatible and can be used in all refrigerator models that use the RPWF. However, if your refrigerator model requires the RPWFE specifically, you will not be able to use the RPWF, or any replacement for the RPWF.

The FF21130 is a FiltersFast brand product that is certified for NSF Standard 42, 53 and 401, which verifies that the product is made from safe and durable materials with claims backed by test data.
