Frigidaire WF3CB (PureSource 3) questions, answered
How often should I replace the Frigidaire WF3CB?
Replace it every six months or after 200 gallons, whichever comes first. Frigidaire also instructs users to prime a new cartridge by running and discarding about 1.5 gallons of water.
Sources: [1]
What refrigerators does the WF3CB fit?
It fits the 32 refrigerator models in Frigidaire's current WF3CBC Works With These Models list. Check the exact appliance model against that list before ordering; a family name or visual resemblance alone does not establish fit.
Sources: [1]
What does the Frigidaire PureSource 3 filter reduce?
Verified health claim
The active IAPMO R&T listings name chlorine taste and odor, nominal particulate Class I, 13 NSF/ANSI 53 claims, and atenolol, ibuprofen, trimethoprim and microplastics under NSF/ANSI 401. The full claim-by-claim list is shown in this record and should not be extended to contaminants absent from the listings.
Is the Frigidaire WF3CB certified?
How do I install a WF3CB filter?
Push the old cartridge to release it, slide the new WF3CB into the housing, and push until it locks. Then run and discard about 1.5 gallons of water and reset the refrigerator's filter-status indicator; Frigidaire's current instructions do not require shutting off the water supply for the cartridge change.

What we could not establish, and why
| Field | Why it is blank |
|---|---|
| identity.upc | The Frigidaire product page, current performance data sheet, refrigerator manual and confirmed Amazon listing did not publish a carton UPC for this exact WF3CB SKU. |
| certified.certIndexKey | A repository search for WF3CB and PureSource 3 found no match in the local certification index; live IAPMO R&T and WQA checks were recorded separately and do establish current listings. |
| fit.bathroomsServed | Bathroom sizing does not apply meaningfully to this point-of-use refrigerator cartridge, and Frigidaire's product page and data sheets publish no bathroom count. |
| fit.householdSize | Frigidaire's product page, performance data sheet and refrigerator manual publish capacity and flow but no supported household-size range. |
| fit.roOutputGpd | This is an activated-carbon refrigerator cartridge, not a reverse-osmosis membrane; the manufacturer documents no RO output. |
| fit.roTankCapacity | This is an activated-carbon refrigerator cartridge without an RO storage tank; the manufacturer documents no RO tank capacity. |
| fit.dimensions | Frigidaire publishes retail-package dimensions, not verified cartridge dimensions; retailer measurements were not substituted for an OEM dimensional specification. |
| fit.connectionSize | The Frigidaire product page, performance data sheets and refrigerator manual describe a push-lock cartridge but do not publish a connection-size measurement. |
| fit.requiresElectricity | The cartridge itself has no published electrical specification; the refrigerator's electrical requirement was not imputed to the element. |
| fit.requiresDrain | The cartridge documentation does not state a drain requirement, and absence was not inferred from the installation illustrations. |
| cost.msrp | Amazon labels a higher reference price as a list price that may come from a manufacturer, supplier or seller; no manufacturer USD MSRP for the exact WF3CB was established. |
| cost.wasteRatio | Waste ratio is an RO-specific metric; the Frigidaire activated-carbon cartridge documentation publishes no product-water-to-waste-water ratio. |
| cost.warranty | The manufacturer sources reviewed refer readers to the refrigerator guide for warranty information but do not state an exact warranty term for the standalone WF3CB cartridge. |
| cost.moneyBackGuarantee | No Frigidaire money-back guarantee specific to the WF3CB cartridge was located on the product page, data sheets or manual. |
| install.estimatedHours | Frigidaire and the exact-model installation video explain a short tool-free swap but publish no duration; a time estimate was not invented. |
