Frigidaire PureSource 2 Refrigerator Replacement Filter WF2CB
Lower-concern water filter; activated carbon is a standard PFAS removal media, but no third-party PFAS claims or testing disclosed.
PureSource 2 filters use activated carbon, which is well-established for removing PFAS and other contaminants from drinking water. Frigidaire makes no explicit PFAS claims or disclosures about the filter composition.

The full breakdown
What it's made of and why it matters
The WF2CB uses granular activated carbon as its primary filtration medium, a well-established material that adsorbs chlorine, odors, and some chemical contaminants through a porous structure. The housing is plastic, typically polypropylene or similar food-grade polymer, which sits inside the refrigerator's cold environment and does not experience heating. Activated carbon itself is inert at refrigeration temperatures and poses no leaching risk under normal use conditions.
The brand's record and disclosure
Frigidaire has not published third-party certifications (NSF, WQA) or independent PFAS testing data for the PureSource 2 line. The brand's public documentation focuses on chlorine and taste/odor reduction rather than heavy metals or emerging contaminants. No recalls or safety violations are recorded for this specific filter model. Frigidaire's parent company (Electrolux) maintains general food-safety compliance but does not disclose detailed filter media sourcing or contamination screening.
How it compares in its category
Refrigerator filters are typically lower-performance than standalone pitcher or under-sink systems because they prioritize cost and ease of use over exhaustive contaminant removal. The WF2CB is a common OEM replacement, meeting baseline NSF/ANSI Standard 42 (aesthetic filtration) in most markets but lacking third-party verification for this specific SKU. Premium alternatives (e.g., Aqua-Pure, Cuno) often carry NSF certification and explicit testing data; the WF2CB trades transparency for affordability and brand compatibility.
If you buy it
Replace the filter every 6 months or per manufacturer guidance; delayed replacement can allow bacterial biofilm growth inside the cartridge, especially if the refrigerator sits unused for extended periods. Ensure the filter housing is clean and that water lines are flushed after installation to remove loose carbon particles. Do not use with untreated well water or highly contaminated sources; this filter is designed as a secondary polishing step, not primary treatment. Store unopened filters in a cool, dry place and discard if the package is damaged or the cartridge appears compromised.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Bacterial growth in filter media if unmaintained
Activated carbon, while inert, provides a growth substrate for biofilm if water flow stagnates or filter replacement intervals are missed. Risk is mitigated by regular 6-month replacement and keeping the refrigerator's water line clean.
Loose carbon particles or fines post-installation
User reports document initial black-tinged water or particles immediately after installation; this is cosmetic and resolves within 1-2 days of water flushing but is not a safety hazard.
Plastic housing leachables under thermal stress
The polypropylene housing operates well below its melting point inside a refrigerator (typically 40F or below). No documented leaching of BPA, phthalates, or other polymer additives has been reported for this filter model under normal use.
Microbial contamination from source water not addressed by filter
Activated carbon does not reliably remove bacteria or viruses; if source water is microbiologically unsafe, this filter alone is insufficient. Use only with municipally treated water or verify source safety independently.
Inadequate contaminant reduction claims without third-party verification
Frigidaire markets chlorine and taste/odor reduction but does not disclose independent testing for heavy metals, pesticides, or pharmaceuticals. Consumers relying on this filter for comprehensive water quality should verify actual source water quality via external testing.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
