FAQs

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

No. The EPTWFU01 and ULTRAWF 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 only NSF 42 and 53. They cover different Frigidaire refrigerator model generations and are not interchangeable under any circumstances.

Is the EPTWFU01 the same as 242069801 or EWF02?

Yes. 242069801 and EWF02 are alternative part numbers that refer to the same EPTWFU01 PureSource Ultra II filter format. If your refrigerator currently shows either of those codes on the existing filter label, the EPTWFU01 is the correct replacement to order.

What does NSF 401 certification mean for the EPTWFU01 water filter?

NSF 401 is an independent certification that confirms the filter has been tested and verified to reduce select emerging trace compounds not covered by NSF 42 and 53 alone. Whether these compounds are present in your water supply depends on your local water conditions. Checking a current water quality report from your municipal provider confirms whether NSF 401 coverage is relevant for your household.

Is the EPTWFU01 available as part of a combo pack with an air filter?

Yes. The EPTWFU01 is available paired with the PAULTRA2 Pure Air Ultra II air filter as a combo pack for compatible latest generation Frigidaire models requiring both the water filter and air filter on the same 6 month replacement schedule.

Does the Frigidaire EPTWFU01 filter water going to the ice maker as well as the dispenser?

On most compatible Frigidaire refrigerator models the EPTWFU01 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.

Can I use an aftermarket filter instead of the Frigidaire EPTWFU01?

Aftermarket filters may physically fit the housing but the EPTWFU01 carries NSF 401 certification in addition to NSF 42 and 53, a combination that many aftermarket filters do not match. Using a filter that does not carry all three certifications means reduced coverage across the full range of contaminants the EPTWFU01 is rated for. For consistent tested performance use a certified replacement rated for the EPTWFU01 housing.
