Pur 11 Cup Water Filter Pitcher
Low concern; no identified PFAS triggers, though no testing disclosure exists.
This 11-cup pitcher features activated carbon filtration and a BPA-free plastic body, neither requiring PFAS treatments. PUR hasn't publicly tested or claimed PFAS safety.

What Pur 11 Cup Water Filter Pitcher is made of, ingredients and materials
The Pur 11 Cup pitcher uses an activated-carbon filter cartridge (standard bituminous or coconut-shell carbon) housed in a BPA-free plastic pitcher body. Activated carbon is the industry standard for chlorine, taste, and odor reduction in consumer pitchers and poses no known direct toxicity hazard when properly maintained. The BPA-free plastic construction means the pitcher itself does not introduce bisphenol A or analogous endocrine disruptors into filtered water under normal storage conditions.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial growth if filter cartridge unmaintained
Activated carbon, once saturated, becomes a nutrient medium for bacteria and mold growth if not replaced on schedule. This is a use-and-maintenance hazard, not a manufacturing defect; proper 40-gallon or 2-month replacement cycles mitigate it.
Activated carbon dust or fines ingestion
New filter cartridges may release loose carbon particles; rinsing the cartridge before first use removes most fines. Residual exposure is minimal and non-toxic, but not ideal.
Contaminant breakthrough if cartridge exceeds rated capacity
Overusing a cartridge beyond 40 gallons reduces filtration effectiveness and allows chlorine, VOCs, and other contaminants to pass through unfiltered. This is a performance failure rather than a safety defect, but undermines the product's protective function.
Plastic housing degradation or cracking over time
Repeated filling, freezing if stored near cold surfaces, or drops can compromise the polypropylene pitcher, potentially introducing micro-cracks or hairline leaks. No established leachable hazards from the plastic itself, but structural failure reduces usability.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Pur explicitly markets the pitcher as BPA-free; no reports of leaching from the polypropylene or other plastics used in the housing under normal room-temperature storage. Cold water contact poses negligible risk.

The brand's record and disclosure
Pur (owned by Helen of Troy) maintains NSF certification for some product lines, though the 11 Cup pitcher's specific certifications are not universally published. The brand has not publicly disclosed PFAS testing or mitigation strategies, which is typical of mainstream pitcher-filter manufacturers but represents a transparency gap. No major recalls or contamination incidents involving this specific pitcher model are on record in FDA or CPSC databases.
How it compares in its category
Pitcher-based carbon filters (Pur, Brita, ZeroWater) all rely on activated carbon and are functionally similar; Pur's 11 Cup model is mid-range in capacity and replacement-cartridge cost. This category is considered lower-risk than point-of-use or reverse-osmosis systems because the contact time and volume are modest, and activated carbon does not leach carbon itself into water. However, all pitcher filters require consistent replacement (typically every 40 gallons) to avoid bacterial regrowth and breakthrough of contaminants.
If you buy it
Replace the cartridge every 2 months or 40 gallons of use (whichever comes first) to prevent activated carbon saturation and bacterial colonization in the filter media. Store the pitcher in a cool, dry place away from direct sunlight to avoid algae growth in the clear plastic housing. Do not use the pitcher to filter hot water above room temperature, as this accelerates carbon depletion and can stress the plastic. Rinse the new cartridge with cold water before first use to remove any loose carbon dust.
