FAQs

Is the EPTWFU01 PAULTRA2 combo the same as the ULTRAWF PAULTRA combo pack?

No. These are two distinct combo packs designed for different Frigidaire refrigerator model generations. The EPTWFU01 carries NSF 401 certification in addition to NSF 42 and 53 while the ULTRAWF carries only NSF 42 and 53. The PAULTRA2 is the updated Pure Air Ultra II while the PAULTRA is the earlier Pure Air Ultra. Always confirm both part numbers on the existing installed filters before ordering to ensure the correct combo for your model.

What makes the EPTWFU01 PureSource Ultra II different from the ULTRAWF PureSource Ultra?

The EPTWFU01 carries NSF 401 certification in addition to NSF 42 and 53, covering select trace compounds not addressed by the ULTRAWF. It is also designed for a newer generation of compatible Frigidaire models with a distinct housing design that is not interchangeable with the ULTRAWF housing.

Is the PAULTRA2 the same as the PAULTRA Pure Air Ultra air filter?

No. The PAULTRA2 Pure Air Ultra II and PAULTRA Pure Air Ultra are separate part numbers designed for different Frigidaire refrigerator model generations with distinct housing designs. Check the part number on the existing air filter before ordering to confirm which version your refrigerator requires.

Can I buy the EPTWFU01 and PAULTRA2 separately instead of as a combo pack?

Yes. Both the EPTWFU01 water filter and PAULTRA2 air filter are available as individual replacements. The combo pack is the more convenient and cost-effective option for households replacing both on the same 6 month schedule.

Does my Frigidaire refrigerator need both the EPTWFU01 water filter and the PAULTRA2 air filter?

Compatible latest generation Frigidaire refrigerators that use this combo pack require both filters to maintain full water filtration and air purification performance. The EPTWFU01 filters contaminants from dispensed water and ice while the PAULTRA2 reduces airborne odor compounds and ethylene gas inside the refrigerator compartment. Both need replacing on schedule for consistent performance across both systems.

Where can I find my Frigidaire refrigerator model number to confirm compatibility?

The model number label is typically located inside the fresh food compartment along the upper door frame or side wall. On some Frigidaire models it may also appear on the back of the refrigerator near the compressor panel.
