Frigidaire WF2CB vs WF3CB vs ULTRAWF 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 or in the grille at the base of the refrigerator depending on the model. 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 WF2CB Filter?

Order a fresh WF2CB 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, and VOCs 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 WF2CB PureSource 2 Water Filter

1. Locate the filter housing inside the Frigidaire refrigerator fresh food compartment or base grille depending on your model
2. Press the release button to eject the old WF2CB filter from the housing
3. Pull the old filter straight out
4. Align the new WF2CB filter with the housing inlet and insert it firmly
5. Push until the filter clicks securely into the locked 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 WF2CB PureSource 2 water filter?

You can order the Frigidaire WF2CB 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 WF2CB the same as the WF3CB or ULTRAWF filter?

No. The WF2CB, WF3CB, and ULTRAWF are separate part numbers with different housing designs and different installation types. The WF2CB uses a push-button eject design while the WF3CB and ULTRAWF use twist-in designs. They are not interchangeable under any circumstances.

Is the WF2CB the same as PureSource 2 or 218904501?

Yes. PureSource 2, 218904501, 218732309, and FC-100 are alternative names and part numbers that refer to the same WF2CB filter format. If your refrigerator currently shows any of these codes, the WF2CB is the correct replacement to order.

Does the Frigidaire WF2CB filter water going to the ice maker as well as the dispenser?

On most compatible Frigidaire refrigerator models the WF2CB 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 WF2CB covers both functions on your unit.

What is the key difference between the WF2CB and the WF3CB installation?

The WF2CB uses a push-button eject installation design while the WF3CB uses a twist-in design. This means the two filters are not interchangeable even if they look similar. Always confirm the installation type matches your existing filter housing before ordering.

Can I use an aftermarket filter instead of the Frigidaire WF2CB?

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 in your Frigidaire refrigerator, a certified replacement rated for the WF2CB housing is the more reliable choice.
