Frigidaire EPTWFU01 vs ULTRAWF vs WF3CB Water Filter

This is the most important section if you are unsure which Frigidaire refrigerator water filter to order.

How do I check my current filter part number?

The part number is printed directly on the filter currently installed in your refrigerator. The filter housing is typically located inside the fresh food compartment. Remove the existing filter and check the label before ordering to avoid a mismatch.

What happens if I order the wrong filter?

An incorrectly ordered filter will not seat properly in the housing and will not deliver effective water filtration. In some cases it may appear to fit but leave gaps at the housing connection that allow unfiltered water to pass through to the dispenser and ice maker. Always order by part number rather than by appearance or size.

How Often Should You Buy a Replacement Frigidaire EPTWFU01 Filter?

Order a fresh EPTWFU01 every 6 months or 200 gallons, whichever comes first. Households with higher water consumption may reach the 200 gallon mark before the 6 month period is up. A saturated carbon block past its service life stops reducing chlorine, lead, VOCs, and select trace compounds effectively and may begin releasing previously captured contaminants back into the water. Replacing on schedule rather than waiting for taste or flow changes maintains consistent filtration performance through the full service life.

How to Install the Frigidaire EPTWFU01 PureSource Ultra II Water Filter

1. Locate the filter housing inside the Frigidaire refrigerator fresh food compartment
2. Twist the old filter counterclockwise until it releases from the housing
3. Pull the old EPTWFU01 filter straight out
4. Align the new filter with the housing inlet and insert it firmly
5. Twist clockwise until it locks securely into position
6. Run 2 to 3 gallons of water through the dispenser before drinking
7. Reset the filter indicator light per the Frigidaire refrigerator user guide

FAQs

Where can I buy the Frigidaire EPTWFU01 PureSource Ultra II water filter?

You can order the Frigidaire EPTWFU01 directly from the shop link on this page. Confirm the part number against your existing filter label before completing your purchase to avoid ordering the wrong filter for your model.

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

No. The EPTWFU01 and ULTRAWF are separate part numbers with different housing designs. The EPTWFU01 is the latest generation filter and carries NSF 401 certification in addition to NSF 42 and 53, while the ULTRAWF carries only NSF 42 and 53. They are not interchangeable.

Is the EPTWFU01 the same as PureSource Ultra II or 242069801?

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

What makes the EPTWFU01 different from other Frigidaire water filters?

The EPTWFU01 carries NSF 401 certification in addition to NSF 42 and 53, which means it is tested to reduce select trace compounds not covered by NSF 42 and 53 only filters. This makes it the most comprehensive certified water filter option across the current Frigidaire water filter lineup.

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 to verify whether the EPTWFU01 covers both functions on your unit.

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

Aftermarket filters may physically fit the housing but certification levels and contaminant reduction performance vary widely between manufacturers. The EPTWFU01 carries NSF 401 certification in addition to NSF 42 and 53, a combination that many aftermarket filters do not match. For consistent, tested performance in your Frigidaire refrigerator, a certified replacement rated for the EPTWFU01 housing is the more reliable choice.
