Frigidaire refrigerator water filter replacement guide

Start a Frigidaire water-filter replacement by reading the installed cartridge marking and complete refrigerator model. ULTRAWF, WF3CB and FPPWFU01 name different families. The table of names below identifies them; only your exact model's manufacturer listing establishes which one fits.

Safety boundary

Stop dispensing if water leaks. Avoid wet outlets and shut off an accessible water supply only when safe and consistent with the model instructions.
Use the exact model manual for cartridge access. Do not pull the refrigerator out, open panels, force a cartridge or modify the water plumbing for these checks.

Part typeFrigidaire refrigerator water-filter family identification

Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.

Required identifiers

Complete model number from the refrigerator label, including its suffix
Installed cartridge code and family name
Exact-model Frigidaire filter-finder result or applicable owner manual

Compatibility rules

PureSource Ultra is the ULTRAWF family; PureSource 3 is WF3CB; PurePour PWF-1 is FPPWFU01.
Use the installed cartridge as a starting clue, then verify it against Frigidaire's full-model filter finder or manual before ordering.
A family name or generic product page does not establish fit for an unlisted refrigerator or revision.

Never assume

ULTRAWF, WF3CB and FPPWFU01 are mutually interchangeable.
A cartridge fits because it is Frigidaire, looks similar or fits a neighboring model.
All filter families share removal, flush, reset or replacement-interval instructions.

Which name belongs to which cartridge?

PureSource Ultra — ULTRAWF
PureSource 3 — WF3CB
PurePour PWF-1 — FPPWFU01

What if the current cartridge and model lookup disagree?

Pause the order. An installed filter can be a clue without being proof of the correct prior choice. Recheck the entire refrigerator label, the cartridge code and the model manual; ask Frigidaire to resolve the mismatch. This family guide contains no new exact-model fit claims.

What happens after choosing the filter?

Follow the matched cartridge and model instructions for installation and flushing. A filter-light reset is a separate control task. Uneven flow or leakage after replacement deserves its own checks rather than another guessed cartridge purchase.
