Frigidaire WF3CB (PureSource 3) Water Filter Compatibility Finder

By Neo Pecorro, Founder · Last updated August 27, 2026

Buying the wrong Frigidaire water filter wastes money and can cause a poor seal in the housing. The WF3CB, sold as PureSource 3, is a push-to-lock filter that fits Frigidaire, Electrolux, and Kenmore side-by-side refrigerators manufactured after 2009. FilterFitNow verifies your match against manufacturer part-fitment data and independent retailer cross-references, not just similar-looking part numbers.

Find Your WF3CB Filter Match

Use the Refrigerator Water Filter Compatibility Finder → and enter WF3CB or your refrigerator’s model number to confirm your exact match.

WF3CB Model Reference

WF3CB Model Reference

Filter Code	Compatible Series	Replacement Interval
WF3CB / PureSource 3 (242069601, 242294501, AP4567491)	Frigidaire, Electrolux & Kenmore side-by-side refrigerators made after 2009 — including BFHS2611LM, CRSE233T, CRSE263T, CRSH232P, CRSH237, and CRSH238 series	200 gallons / about 6 months (Frigidaire’s official WF3CBC product page)

Frigidaire does not publish a complete model list for this filter through its own site — fitment is confirmed by filter location and refrigerator generation (side-by-side, filter in the back right corner, made after 2009) rather than an exhaustive model number list from a single source. If your side-by-side Frigidaire was made after 2009 and the filter sits in the back right corner, WF3CB is very likely your match — confirm with the finder tool above or the code on your existing filter before ordering.

How We Verify Compatibility

We don’t confirm a fit until it clears three checks:

• Manufacturer documentation and official part-fitment specs
• Compatibility lists from filter makers and retailers
• User-reported data, cross-checked against the first two

Any disagreement between sources gets flagged as unverified rather than published as fact. See the full verification process →

How Do You Replace a Frigidaire WF3CB Filter?

Push to release the old cartridge, pull it out, slide the new WF3CB into the housing and push until it locks into place, then flush the filter before drinking. (Frigidaire’s official WF3CBC product page)

1. Locate the filter in the top right-hand corner of the refrigerator’s fresh food compartment.
2. Press the existing filter in to unlock it, then pull it straight out.
3. Check the code printed on the old filter to confirm your replacement matches.
4. Align the new filter with the slot and push it firmly into the housing until you hear it click.
5. Run the dispenser for about 3 minutes (roughly 1.5 gallons) to prime the filter, discarding that water before drinking.

Frequently Asked Questions

How do I know if my Frigidaire uses the WF3CB filter?

Check the filter compartment in the back right corner of your side-by-side refrigerator’s interior. If your fridge was made after 2009 and uses a push-to-lock filter in that location, WF3CB is very likely correct — confirm with the code on your existing filter or the finder tool above.

How long does the WF3CB filter last?

About 6 months or 200 gallons, whichever comes first.

Can I use a compatible filter instead of a genuine Frigidaire WF3CB?

Compatible third-party filters exist, but fit and filtration performance vary. We only confirm a match when it passes our verification process — see above.

Is WF3CB the same as ULTRAWF?

No. ULTRAWF is a separate, higher-capacity Frigidaire filter for different models. Check the code on your existing filter before assuming either one fits.
