Why OEM, not compatible?
For most homeowners, our Compatible WF3CB (NSF 42/53 certified, $11.99) is the smart choice. Buy the OEM if:
- You are still under Frigidaire warranty and want it intact
- You prefer the official packaging and serial number for records
Installation (2 minutes, no tools)
- Locate the filter compartment (top-right inside the fridge or bottom grille)
- Push in and rotate or pull the old filter to release
- Insert the new WF3CB and push until it clicks
- Run 2-3 gallons through the dispenser to flush carbon fines
