PUR Plus 11 Cup Water Filter Pitcher
Lower concern, standard carbon-filter design, but PUR provides no public PFAS disclosure.
PUR Plus pitchers use activated carbon filtration, a method that doesn't inherently require PFAS. However, PUR (owned by Pentair) makes no public statement about PFAS in their filters or plastic components. The pitcher housing is standard food-grade plastic.

The full breakdown
What it's made of and why it matters
The PUR Plus 11 uses activated carbon as its primary filtration media, a well-established, inert material that binds chlorine, taste, and odor compounds without leaching. The pitcher housing is plastic (likely polypropylene or similar food-contact polymer), which is stable at room temperature and not heated during normal use. No ceramic, enamel, or metal surfaces are in contact with stored water, eliminating leaching risks common in cookware-style filters.
The brand's record and disclosure
PUR is owned by Culligan and has maintained NSF/ANSI 53 certification for the Plus line, indicating third-party validation of contaminant reduction claims. The brand does not publicly disclose PFAS removal testing or stance, which is typical for consumer pitcher manufacturers but reflects limited transparency on emerging contaminants. No significant product recalls or safety controversies are on record for this model.
How it compares in its category
Pitcher filters like PUR Plus occupy the middle ground: cheaper and simpler than under-sink systems but less precise than reverse-osmosis units. Activated carbon pitchers are the category standard and carry no inherent material hazards that distinguish them. Performance differences between major brands (PUR, Brita, ZeroWater) are modest; choice typically hinges on cartridge cost and filter longevity rather than safety.
If you buy it
Replace the cartridge every 2, 3 months or after 100 gallons, whichever comes first, to prevent bacterial growth in saturated carbon and maintain filtration. Do not store the pitcher in direct sunlight or extreme heat, as plastics can degrade over time if exposed to thermal stress. Rinse the housing and lid weekly and allow to air dry to prevent mold; keep the pitcher in a cool, dark cabinet. Never run the pitcher through a dishwasher, as heat and detergent can compromise seals.
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 cartridge
Activated carbon is a nutrient-free medium but can accumulate biofilm if not replaced on schedule or if water sits stagnant; risk is operational rather than material-based and is mitigated by regular cartridge changes.
Plastic housing leachables (BPA/BPS)
Food-contact plastics in modern pitcher designs are typically BPA-free and tested for leaching; no specific recalls or complaints are on record for PUR Plus housing at room temperature.
Activated carbon dust or particle shedding
New cartridges can release fine carbon particles into the first pitcher of filtered water; flushing the cartridge with tap water before first use is recommended by manufacturers to remove loose media.
Seal degradation and water bypass
Gaskets and seals in the pitcher can harden or shrink over 1, 2 years, potentially allowing unfiltered water to bypass the cartridge; regular inspection and replacement of worn seals is prudent but not a chemical hazard.
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.
