Refrigerator Maintenance 101: Keeping Water and Air Filters Fresh in 2026
By Chloe Bennett
Frigidaire has shifted its water filtration architecture over recent model generations, leaving many homeowners confused about which genuine OEM filter cartridge fits their specific French-door or side-by-side refrigerator. The two dominant form factors across the Gallery lineup are the PureSource Ultra II (EPTWFU01) and the PurePour PWF-1 (FPPWFU01). While both cylinders share similar exterior styling and slide into the upper-right interior ceiling or the door pocket, their locking tabs and push-to-release mechanisms differ enough to prevent interchangeability.
The PureSource Ultra II relies on an extended push-and-turn cylindrical housing engineered for earlier Gallery refrigerators, featuring dual O-rings designed to withstand standard household pressures between 30 and 100 psi. In contrast, the PurePour PWF-1 employs an effortless slide-in snap mechanism, favored in contemporary French-door configurations. Installing the incorrect housing or forcing a misaligned unit can crack the water filter manifold, leading to slow interior leaks that pool beneath the lower crisper drawers before being detected.
