Start with the complete device model
Every published Frigidaire catalogue family has its own model answer here. Keep the full prefix and digits because the WF and PWF names describe different cartridges.
Published model records
Each route keeps the documented device model, filter reference, region and manufacturer sources together. A source review records a documentary check against manufacturer materials; it does not mean the filter was physically fitted or tested.
FPPWFU01, FPPWFU02 and EPTWFU01 each have a distinct answer. ULTRAWF, WF3CB, WF2CB and WFCB are also separate families rather than shorter aliases.
