Frigidaire WF3CB PureSource 3 refrigerator filter guide

WF3CB identifies PureSource 3

Frigidaire uses WF3CB for its PureSource 3 water-and-ice refrigerator filter. This family is different from ULTRAWF, EPTWFU01 PureSource Ultra II, and FPPWFU01 PurePour PWF-1.

A listing that says only Frigidaire refrigerator filter is too broad. Record the appliance model and the exact code on the current cartridge before choosing a replacement.

Check model and cartridge together

Use Frigidaire's filter finder or the refrigerator owner's manual to identify the required family. If the result is WF3CB, compare that code with the installed filter and its push-to-lock connection.

• Complete refrigerator model
• WF3CB part number
• PureSource 3 family name
• Push-to-lock connection
• Manufacturer confirmation

Replacement interval and installation

Frigidaire recommends replacing WF3CB about every six months under normal use. Water quality, usage, reduced flow, or the filter-status indicator may call for an earlier change.

Install and flush the cartridge according to the refrigerator manual, reset the indicator only after replacement, and inspect the housing during the first dispensing cycles.
