P.C. Richard & Son Refrigerator Water Filter 9880980

A · Very low PFAS

Lower concern. Standard carbon filter, no known PFAS risk.

Verdict: BuyStandard activated carbon filter with no known contaminant risks; routine replacement and maintenance eliminate bacterial growth concern.

Liebherr refrigerator filters use activated carbon, a material inherently lower risk for PFAS. No brand disclosure on PFAS exists, but carbon filtration itself does not require fluorochemical treatment.

The full breakdown

What it's made of and why it matters

This Liebherr 9880980 filter uses activated carbon as its primary filtration media, a material that adsorbs chlorine, odors, and some organic compounds from refrigerator water supplies. Activated carbon does not leach harmful chemicals into water under normal refrigerator conditions because it operates at low temperature and low pressure. The filter housing is typically food-grade plastic or composite; neither leaches into cold water without degradation. This is a passive mechanical filter with no electrical components or ion-exchange resins that might introduce secondary contaminants.

The brand's record and disclosure

Liebherr is a German appliance manufacturer with established quality control practices and CE marking compliance for European markets. The company does not publicly disclose detailed filter composition or third-party certification data on their website, which is common in this category. No recalls or contamination incidents involving Liebherr refrigerator filters have been established in public records. The brand's silence on PFAS is typical for standard carbon filters, where PFAS exposure risk is not a known issue.

How it compares in its category

Refrigerator water filters across brands (Whirlpool, GE, LG, Liebherr) use nearly identical activated carbon technology and pose similar low-risk profiles. Liebherr filters are OEM products, meaning they are manufactured to match the appliance design rather than being aftermarket or third-party generic options. Aftermarket filters sometimes underperform or crack, but OEM filters carry lower variability risk. Pricing is typically higher than third-party alternatives, reflecting OEM certification rather than superior filtration.

If you buy it

Replace this filter every 6 months or when water flow noticeably decreases, following the refrigerator manual's schedule. Store in a cool, dry place before installation; do not expose to heat or sunlight, as activated carbon can degrade and release fine particles. After installation, run water for 30 seconds before drinking to flush any loose carbon dust. Ensure the filter housing is properly seated in the refrigerator to prevent bypass; water bypassing the filter defeats contamination removal.

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.”

Possible

Bacterial growth in filter housing

Activated carbon filters can harbor bacteria if not replaced regularly or if water stagnates in the housing. This risk applies to all refrigerator filters and is mitigated by following the 6-month replacement schedule and ensuring the refrigerator maintains cold temperatures consistently.

None known

Housing material leaching

No documented cases of leaching from Liebherr filter housings. Food-grade plastic and composite materials used in OEM housings are regulated under FDA and EU food-contact rules and do not leach under cold water conditions.

Possible

Activated carbon dust release

Loose carbon particles may be released during first use if the filter is not flushed. This is cosmetic rather than toxic but can affect water taste and appearance. Rinsing the water line for 30 seconds resolves this.

Possible

Filter bypass and seal failure

Improper installation or worn seals allow unfiltered water to pass into the system. This is a design/installation failure rather than a material toxicity issue but defeats the filter's function. Check that the filter cartridge seats fully and inspect the housing gasket annually.

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.
