The filter is an universal external replacement model for refrigerators. If your refrigerator does not include a built-in filtration system, you can use this inline filter. An inline filter connects to the incoming water line for the refrigerator and filters the water that feeds the ice machine and water dispenser. The inline filter is often put on the back of the refrigerator.
RFC0300A features simple push-in “quick connect” fittings on each end and can work with 1/4 copper, poly or cpvc water line.
