FAQs

Is the Frigidaire ULTRAWF the same as the EPTWFU01 PureSource Ultra II water filter?

No. The ULTRAWF and EPTWFU01 are separate part numbers with different housing designs and different certification levels. The EPTWFU01 carries NSF 401 certification in addition to NSF 42 and 53 while the ULTRAWF carries NSF 42 and 53 only. They are not interchangeable. Always confirm the correct part number on the existing installed filter before ordering.

Is the ULTRAWF the same as 242294402 or 241791601?

Yes. 242294402 and 241791601 are alternative part numbers that refer to the same ULTRAWF PureSource Ultra filter format. If your refrigerator currently shows either of those codes on the existing filter label, the ULTRAWF is the correct replacement to order.

Is the ULTRAWF the same as the WF3CB or FPPWFU01 water filter?

No. The ULTRAWF, WF3CB, and FPPWFU01 are separate part numbers with different housing designs built for different Frigidaire refrigerator model configurations. Despite all using twist-in designs, housing tolerances differ between each code and cross-code substitution is not reliable. Always order by part number.

Does the Frigidaire ULTRAWF filter water going to the ice maker as well as the dispenser?

On most compatible Frigidaire refrigerator models the ULTRAWF serves both the water dispenser and the ice maker from a single filter housing. Confirm this against your specific model in the Frigidaire user guide before ordering.

Is the ULTRAWF available as part of a combo pack with an air filter?

Yes. The ULTRAWF is available paired with the PAULTRA Pure Air Ultra air filter as a combo pack for compatible Frigidaire models requiring both the water filter and air filter on the same 6 month replacement schedule.

Can I use an aftermarket filter instead of the Frigidaire ULTRAWF?

Aftermarket filters may physically fit the housing but certification levels and contaminant reduction performance vary widely between manufacturers. Using a filter that does not carry NSF 42 and 53 certification means contaminant reduction claims are unverified. For consistent tested performance use a certified replacement rated for the ULTRAWF housing.
