PUR Plus 30-Cup Water Filter Pitcher Dispenser DS1811Z
Low concern; standard carbon filter without known PFAS coatings, though PUR hasn't tested.
This PUR pitcher uses activated carbon filtration, a lower-PFAS technology, with a BPA-free plastic body and no Teflon-family coating coatings. PUR hasn't publicly tested or disclosed PFAS information.

What’s concerning
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Bacterial growth if filter or water not maintained
Any pitcher filter with standing water can develop biofilm inside the spigot valve and filter housing, especially if the pitcher sits unused for days. Emptying and drying weekly, replacing filters on schedule, and avoiding warm environments reduce this risk substantially.
Filter cartridge housing material safety
The filter cartridge itself is not a transparent hazard, but replacement cartridges from PUR have not been independently analyzed for PFAS content in the housing or adhesives. If PFAS-containing materials are used in manufacturing, they could theoretically migrate into filtered water over the filter's lifespan.
Degradation of plastic seals or valve over time
The spigot valve and pitcher seals are plastic and may crack, shrink, or degrade after 1-2 years of repeated fill-drain cycles and exposure to chlorinated water. Degraded seals can allow unfiltered water bypass or bacterial entry; inspect visibly and replace the pitcher if cracks appear.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Plastic leaching from pitcher body or lid
PUR specifies BPA-free plastic, and no reports of off-gassing or leaching of other plasticizers (phthalates, BPS) have been documented for this model. Cold water contact poses minimal risk; heat exposure above 120°F is the primary concern, but pitcher design is not intended for hot water.
The full breakdown
What it's made of and why it matters
The DS1811Z pitcher body is BPA-free plastic (polypropylene or similar food-grade thermoplastic), which eliminates the endocrine-disrupting concern associated with older bisphenol A formulations. The filter cartridge uses activated carbon, a benign adsorbent that does not leach into water under normal use. The pitcher lid and spigot are also plastic; these components do not involve glazes, enamels, or ceramic coatings that could introduce lead or cadmium. No Teflon-type coating (Teflon) or related Teflon-family coating are used in the filtration media itself.
The brand's record and disclosure
PUR (the manufacturer) has not made public commitments to PFAS testing or transparency in water filtration products, despite PFAS being a known concern in some carbon filters and filter housings. The company holds NSF International certification for its filter cartridges, which covers reduction of chlorine and some chemical contaminants, but NSF certification does not mandate PFAS disclosure. No product recalls, contamination incidents, or safety complaints tied to this specific model have been documented in public databases. PUR's parent company (Helen of Troy) has not issued category-wide PFAS testing statements.
How it compares in its category
This pitcher filter is a typical activated-carbon design, functionally similar to Brita, ZeroWater, and store-brand equivalents; all carry the same baseline plastic-leaching and bacterial-growth risks if poorly maintained. The 30-cup capacity is mid-range; larger pitchers reduce filter use frequency but increase water stasis risk. The BPA-free designation is now standard across the category and does not confer advantage, though it does eliminate a historical hazard. No data suggests PUR pitchers leach more or fewer contaminants than competitors when filters are replaced on schedule.
If you buy it
Replace the filter cartridge every 40-80 gallons (typically 2-3 months with household use); expired filters lose adsorption capacity and can harbor bacterial biofilm. Do not fill the pitcher with hot water above 120°F, as extended heat exposure may degrade plastic seals and increase leaching. Empty and dry the pitcher at least weekly to prevent standing water and mold growth inside the basin or spigot. Use only PUR-branded or compatible replacement cartridges; third-party filters may not fit correctly or may introduce contaminants.
