PUR 7-Cup Water Filter Pitcher
Lower PFAS concern, though PUR hasn't publicly stated PFAS commitments.
PUR's 7-cup pitcher features standard activated carbon and ion-exchange resin filters in a plastic body. These materials carry lower PFAS risk than nonstick or water-resistant treatments, but PUR has not disclosed PFAS testing.

What PUR 7-Cup Water Filter Pitcher is made of, ingredients and materials
The PUR 7-Cup pitcher body is typically food-grade plastic (polypropylene or copolyester blend), chosen for durability and safety at room temperature. The filter cartridge contains activated carbon and ion-exchange resin to reduce chlorine, sediment, and some heavy metals from tap water. Neither material is known to leach hazardous compounds under normal cold-water use, though plastic degradation accelerates if pitcher is left in direct sunlight or filled with hot water.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial growth in filter cartridge or pitcher if neglected
If water sits in the pitcher longer than 2-3 days without use or cartridges are not replaced on schedule, activated carbon can harbor microbial growth; this is a maintenance issue common to all pitcher filters, not unique to PUR.
Cartridge housing or seals degradation over time
Plastic seals and cartridge housings can degrade with repeated use and age, potentially allowing unfiltered water bypass; no widespread defect reports exist, but degradation is typical after 1-2 years of regular use.
PFAS
Standard activated-carbon pitcher filters are not designed to remove PFAS or most pharmaceuticals; municipal testing has documented PFAS in water supplies, and PUR has not published data on PFAS filtration efficacy.

Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
PUR pitchers meet NSF food-contact standards and polypropylene is not known to leach BPA under cold-water conditions; no recalls or test results indicating leaching have been reported for this product line.
Source, FDA ↗Microplastics
No peer-reviewed studies or recalls document microplastic release from PUR pitcher plastic or cartridge media under normal use; polypropylene is chemically stable at room temperature.

The brand's record and disclosure
PUR is owned by Helen of Troy and markets its filters as NSF-certified for taste and odor reduction. The company has not publicly disclosed PFAS testing or removal claims, which is notable given that some municipal water supplies now contain measurable PFAS. PUR has no established recalls or safety controversies tied to pitcher plastics or cartridge materials, and the brand maintains third-party NSF Standard 42 certification for chlorine and sediment reduction.
How it compares in its category
PUR pitchers are mid-range in the consumer filter market, comparable to Brita in design and certification scope. Unlike some competitors, PUR does not market PFAS-specific filtration; most pitcher filters in this category (carbon-based) offer limited or no PFAS removal. The 7-cup size and cartridge cost are typical for the category, and replacement frequency (every 2-3 months) is standard.
If you buy it
Store the pitcher in a cool, dark cabinet away from direct sunlight to minimize plastic aging. Do not fill with hot water or leave filled water sitting longer than 48 hours to avoid bacterial growth in the cartridge. Replace cartridges on schedule (roughly every 40 gallons or 2 months of typical use) and rinse the pitcher and lid weekly. If local water has been flagged for PFAS, this pitcher alone will not reliably remove it; consider pairing with a whole-home system or verified PFAS-removal filter if exposure is a concern.
