Why Frigidaire names collide like this
Frigidaire’s cartridge codes encode program and revision, not readability, and the marketing names (PureSource, PurePour) rotate across generations. The result: two current cartridges whose codes share seven characters. The old cartridge in your fridge is the only naming authority that matters; read it, or photograph it for the free photo matcher and skip the decoding entirely.
Ordering logic for either format
We sell both as Genuine OEM cartridges, below typical retail prices. If your city water report flags lead or PFAS and your fridge takes EPTWFU01, the Genuine OEM PureSource Pro adds NSF/ANSI 53 and 401 coverage, the strongest stack in our catalog. Wrong pick despite everything? $1,000 wrong-fit guarantee, 365-day returns.
Frequently asked questions
My Electrolux manual says EWF02. Which column am I in?
EWF02 is the Electrolux twin of the EPTWFU01 housing: order the EPTWFU01 format.
The old cartridge is unreadable. Now what?
Photograph the cartridge and the sticker inside the fridge door, and run both through the photo matcher; if it stays ambiguous, email us the fridge model number and a real person confirms the fit the same day.
Where do ULTRAWF and WF3CB fit in?
They are the earlier PureSource generations for 2009-2018 models: the full family map is in EPTWFU01 vs ULTRAWF.
