Sediment and clogging for WF2CB
Replace earlier when sediment causes a sustained flow reduction. The published Frigidaire record identifies this cartridge as PureSource 2 Water Filter.
Start with fit verification
Match the complete refrigerator model and the code printed on the existing cartridge. Frigidaire PureSource 2 filter. Exact refrigerator models are taken from the manufacturer compatibility chart. Do not infer compatibility from color, overall shape or brand alone.
Service baseline
The available record uses 6 months. Water quality, usage and long periods of inactivity may justify earlier service.
Safe action
Follow the model-specific slide-and-click installation instructions and flush before use. If the cartridge does not seat normally, water does not return after flushing, or the housing leaks, stop and use the refrigerator’s model-specific manual.
Evidence
Open the linked source before purchase. FilterRef separates published compatibility from general troubleshooting guidance and does not treat an aftermarket cross-reference as automatically equivalent.
