PFAS in Refrigerator Filters: Which Brands Grade Best and Worst

When it comes to selecting a refrigerator water filter, most consumers prioritize contaminant removal and cost—but PFAS (per- and polyfluoroalkyl substances) contamination in the filter media itself is rarely top of mind. Based on available materials and public disclosures reviewed in our database, Kenmore Kenmore 9690 Refrigerator Water Filter 1-Pack emerges as the top-graded option, achieving our model-based estimate of a grade A (100/100 safety score). This product's NSF/WQA/IAPMO certifications and BPA-free construction, combined with transparent material sourcing available in public documentation, position it at the lower end of concern for PFAS presence in the filter matrix itself.

However, the broader refrigerator filter market reveals a cautionary landscape. A significant majority of available filters—including popular brands like Whirlpool's EveryDrop line, LG, and Aqua Fresh models—earn our grade B rating (85/100 safety score), reflecting gaps in third-party PFAS testing disclosure and reliance on brand-stated claims rather than independent verification. This guide examines the current state of PFAS in refrigerator filters, identifies which products show lower concern based on available data, and highlights models to approach with scrutiny.

Why PFAS in Refrigerator Filters Matters

Refrigerator filters are designed to reduce contaminants in drinking water—chlorine, sediment, and sometimes volatile organic compounds. However, many filters use activated carbon and ion-exchange resins that, in some cases, have been manufactured using PFAS-based processing aids or surfactants. While the filter removes some contaminants from water, PFAS can migrate from the filter matrix itself into the filtered water, defeating the purpose of filtration. Based on available materials and data, this association does not automatically mean harm will occur, but it does indicate a risk pathway worth considering when selecting a filter product.

The regulatory gap is significant: the U.S. EPA has not mandated PFAS testing for filter products, and most manufacturers do not voluntarily disclose PFAS presence in their filter media. This places the burden of investigation on consumers and independent testing organizations.

Grade A Winners: Lowest Concern

Kenmore Kenmore 9690 Refrigerator Water Filter 1-Pack

Grade: A (100/100 safety score—our model-based estimate from materials and public disclosure, not a lab test)

Materials & Claims: Kenmore states this filter reduces 99% of chlorine and odor, is BPA-free, and carries NSF/WQA/IAPMO certification. These multi-standard certifications require third-party verification of material composition and performance claims, which indirectly supports lower concern for undisclosed PFAS contamination in the filter itself. The brand emphasizes transparency around filter composition in product documentation.

Pros:

• Multiple independent certifications reduce likelihood of unregulated PFAS-processing additives
• BPA-free designation suggests attention to endocrine-disrupting chemistry
• Widely compatible with Kenmore refrigerators; cost-effective at typical retail prices
• Long filter life (approximately 6 months for standard use) minimizes replacement frequency

Cons:

• No published independent lab results specifically testing for PFAS presence in filter media
• Certifications do not explicitly address PFAS; they validate performance on regulated contaminants only
• Limited to Kenmore and compatible LG models; not universal

Clearly Filtered Water Pitcher Replacement Filter 3-Pack

Grade: A (100/100 safety score—model-based estimate)

Materials & Claims: Clearly Filtered distinguishes itself by publishing independent lab results on its website that test for PFAS and PFOA removal. The brand's public data shows third-party verification of filter performance on PFAS-contaminated water samples. This is a rare example of proactive PFAS testing disclosure in the consumer filter market.

Pros:

• Published third-party lab results for PFAS removal—not common in this product category
• Transparency on materials and manufacturing processes builds confidence
• 3-pack format offers value and convenience
• Works with Clearly Filtered pitcher system and compatible models

Cons:

• Pitcher-style filters require manual filling; not integrated into refrigerator like in-line models
• Higher upfront cost than some conventional filters
• Results shown are for PFAS removal from water, not for PFAS in the filter media itself (separate concern)

Clearly Filtered Water Bottle Filter Replacement 25 Gallons

Grade: A (100/100 safety score—model-based estimate)

Materials & Claims: Similar to the pitcher filter above, Clearly Filtered's water bottle filter is marketed with emphasis on independent testing for PFAS and PFOA. The 25-gallon capacity claim reflects the filter's expected lifespan under normal use conditions.

Pros:

• Extended filter life (25 gallons) reduces replacement frequency and cost-per-gallon
• Portable design; can be used in multiple locations
• Third-party PFAS performance data available
• Lightweight and easy to use

Cons:

• Not integrated into refrigerator; requires external pitcher or bottle system
• Does not reduce chlorine taste/odor as effectively as carbon-based filters
• Capacity claims assume ideal conditions; actual lifespan varies with water quality

Grade B: Moderate Concern

The following products earn our model-based grade B (85/100 safety score), indicating moderate concern. These filters generally meet basic safety standards and perform adequately for common contaminant reduction, but lack published PFAS-specific testing data and rely on brand-stated claims rather than third-party verification of PFAS absence or minimal presence in filter media.

Whirlpool EveryDrop EDR1RXD1

Materials & Claims: Whirlpool states that EveryDrop filters reduce chlorine taste and odor and are compatible with multiple Whirlpool refrigerator models. The brand claims the filter uses a blend of activated carbon and ion-exchange resin, but does not disclose PFAS testing or manufacturing practices related to PFAS.

Pros: Wide compatibility; affordable; established brand reputation for appliance parts

Cons: No published PFAS data; relies entirely on brand assurances; unclear filter material sourcing

LG LT700P

Materials & Claims: LG manufactures this filter for its own refrigerators. The company's public documentation emphasizes NSF certification for chlorine and taste/odor reduction, but does not address PFAS in the filter media or published independent testing for PFAS.

Pros: Original equipment filter; guaranteed compatibility with LG fridges; meets NSF standards for regulated contaminants

Cons: No PFAS transparency; proprietary materials not fully disclosed; LG has not published PFAS-specific testing results

Aqua Fresh Refrigerator Water Filter

Materials & Claims: Aqua Fresh markets filters as universal or brand-specific replacements. The brand claims to reduce sediment, chlorine, and odor using activated carbon, but provides no information on PFAS or independent verification of materials.

Pros: Budget-friendly; widely available online; compatible with many refrigerator models

Cons: Minimal material transparency; no third-party PFAS testing; limited quality control documentation publicly available

Other Grade B Products

The following filters share similar profiles—moderate concern due to lack of PFAS-specific disclosure:

• EveryDrop EDR4RXD1
• Aqua Fresh WF537
• EveryDrop EDRARXD1
• LG Select
• LG Waterdrop LT1000PC
• EveryDrop EDR2RXD1
• Whirlpool EveryDrop EDR4RXD1
• Aqua Fresh WF425
• Whirlpool Waterdrop 3-Pack

All of these filters are NSF-certified for basic contaminant reduction and perform adequately in standard refrigerator use. However, none publish independent PFAS testing results or disclose PFAS-related manufacturing practices, placing them in the moderate concern category.

What to Avoid

Based on available materials and data reviewed:

• Filters with no third-party certifications: Avoid any refrigerator filter that does not carry NSF, WQA, or IAPMO certification. These certifications, while not PFAS-specific, ensure some level of independent material verification.
• Brands that make unsubstantiated "PFAS-free" claims: Be skeptical of any filter marketed as "PFAS-free" without published lab results from an accredited independent laboratory. Brand-stated claims are not the same as verified data. Association with a claim is not proof of absence.
• Products with opacity around materials: Filters that do not disclose the specific composition of their filter media (e.g., "proprietary blend") or manufacturing origin offer no basis for assessing PFAS risk. Transparency is a proxy for quality assurance.
• Extremely low-cost filters from unknown manufacturers: While price alone does not determine PFAS risk, filters from manufacturers without established quality standards or public accountability are higher risk by default. These products often lack material traceability.

Our Pick: Best Grade Refrigerator Filter

Based on available materials and public disclosures reviewed, Kenmore Kenmore 9690 Refrigerator Water Filter 1-Pack represents the lowest concern option for consumers seeking an integrated refrigerator filter. Its grade A score (100/100, model-based estimate) reflects multiple third-party certifications, BPA-free designation, and publicly available material documentation—not a guarantee of PFAS absence, but a strong indicator of manufacturing rigor and transparency.

For households using external pitcher or bottle systems, Clearly Filtered Water Pitcher Replacement Filter 3-Pack stands out as the only consumer-accessible filter product with published independent lab results specifically testing for PFAS removal. This transparency sets a higher standard for the category.

Consumers should note that even grade A products have not undergone EPA-mandated PFAS testing for filter media content. Our grades reflect a model-based estimate of lower concern derived from available disclosures, certifications, and published materials—not laboratory confirmation. The refrigerator filter market would benefit from mandatory PFAS transparency and standardized testing protocols, which currently do not exist in the United States.
