Culligan 10 Cup Pitcher
Lower-concern filter design, but verify pitcher plastic composition and actual PFAS removal claims independently.
Culligan/Clearly Filtered pitcher filters use activated carbon, a standard safe filtration material with no known PFAS use. The brand claims PFAS reduction capability.
Brand says: “Clearly Filtered markets its filters as PFAS-reduction products and emphasizes removal of contaminants including 'forever chemicals'”

Why this grade
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The Clearly Filtered pitcher uses activated carbon filtration, which removes chlorine, taste, and odor but relies on mechanical contact between water and carbon granules. The pitcher housing is plastic, likely polypropylene or similar food-grade polymer, but the specific resin composition and whether the pitcher contains BPA or BPS is not disclosed in public materials. Activated carbon itself is inert, but housing durability and potential leaching depend on plastic grade and water temperature exposure over time.
The brand's record and disclosure
Clearly Filtered markets itself as PFAS-free and emphasizes carbon-based filtration without ion exchange or reverse osmosis, which aligns with lower PFAS risk. However, the brand does not appear to hold NSF/ANSI 42 or 53 certification for the Culligan pitcher line, which would independently verify contaminant removal claims. Public disclosure of pitcher material safety testing or third-party verification of actual PFAS removal is limited; claims are largely marketing-driven rather than certification-backed.
How it compares in its category
Pitcher filters with activated carbon are standard consumer products; Clearly Filtered's design avoids legacy PFAS-containing Teflon-family coating (unlike some competitor pitchers with Teflon-type coating or older membranes), which is a relative safety advantage. Most pitcher filters lack NSF certification, making this product typical rather than standout. Performance and safety depend heavily on regular cartridge replacement and water source quality, meaning usage discipline matters more than the product itself.
If you buy it
Replace cartridges every 2-3 months or per manufacturer guidance; standing water in an unused pitcher creates conditions for bacterial growth and mold, especially in warm environments. Do not use boiling water or expose the plastic housing to prolonged heat above 100-120F. Verify the pitcher plastic is food-safe polypropylene or equivalent; if material is not labeled on packaging, contact Clearly Filtered directly. Keep the pitcher sealed when not in use and store in a cool, dark location to slow carbon saturation and plastic degradation.
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 and biofilm in cartridge/housing
Pitcher filters create a static environment where water sits for hours or days; if cartridges are not replaced on schedule (every 2-3 months typical), bacteria and mold can colonize the carbon bed and plastic seams. This is a usage hazard, not a design flaw, but common among pitcher filters.
Plastic housing leaching (BPA/BPS unconfirmed)
The pitcher housing material composition is not clearly disclosed in available product information. If the resin is polycarbonate or recycled plastic of unknown origin, BPA or BPS exposure is possible but unverified; food-grade polypropylene would lower this risk.
Cartridge durability and carbon saturation
Activated carbon filters have a finite lifespan measured in gallons filtered or time, not indefinite performance. Culligan pitchers use proprietary cartridges; once saturated, the filter will not remove contaminants and may even release trapped particles back into water if not replaced promptly.
Housing seal degradation
Silicone gaskets and plastic seams in pitcher filters degrade over months to years with repeated filling and temperature cycling. Degraded seals allow water to bypass the cartridge entirely, defeating the filter's purpose.
Lack of third-party certification verification
The Culligan pitcher line is not listed under Clearly Filtered's NSF-certified products in publicly available certification databases. Consumer claims of PFAS removal or contaminant reduction are not independently verified, making it difficult to assess actual performance.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 68% 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.
Formulations and coatings change between production runs. Always check the current label before buying.
