Frigidaire Refrigerator Water Filters

The 3 Frigidaire filters verified here cover 12 side-by-side, French door and four-door refrigerator families. FPPWFU01 is the push-to-lock PurePour PWF-1, ULTRAWF is the push-to-lock PureSource Ultra, and EPTWFU01 is the twist-in PureSource Ultra II. Frigidaire rates all three for a six-month interval and claims NSF/ANSI 42, 53 and 401 on its current product pages; capacity and flow rate vary by cartridge.

Match the full refrigerator model number before ordering. The similar names are not interchangeable: model-linked Frigidaire manuals in this catalog explicitly separate ULTRAWF from EPTWFU01, and other Frigidaire refrigerators can use PWF-2, WF3CB or WF2CB instead.
