Is PUR NSF certified?

The CRF-950Z anchors the PUR-vs-Brita lead-certification comparison and is the main certified-lead pitcher alternative at the $25-$35 retail price. The honest framing: PUR PLUS (CRF-950Z) is NSF/ANSI 53 lead-certified at the same shelf position as Brita Standard (OB03), which carries NSF/ANSI 42 only and is not lead-certified. For buyers whose main concern is lead, PUR PLUS is the better-evidenced pitcher choice at this price. The trade-off against Brita Elite/Longlast+ (the OB06 cartridge, which is NSF/ANSI 53 lead-certified) is filter life. PUR's CRF-950Z is rated for 40 gallons / about 2 months vs Brita Elite's 120 gallons / 6 months — a 3x longer service cycle. The annual filter cost for a family of 4 favors Brita Elite at ~$36-$48/year vs PUR PLUS at ~$72-$108/year. The CRF-950Z also lacks NSF/ANSI 401 emerging-contaminants certification — for the broader pharmaceutical / BPA / microplastics scope, the MineralClear CRF-9999 cartridge is the in-brand step-up.

The CRF-9999 MineralClear cartridge is the in-brand step-up from the PUR PLUS CRF-950Z lead-reducing cartridge — it adds NSF/ANSI 401 emerging-contaminants certification (15+ pharmaceuticals, BPA, microplastics) on top of the same NSF/ANSI 42 + 53 chlorine + lead + mercury + asbestos scope. The 'MineralClear' name refers to a small mineral-addition step in the cartridge media that adds back trace calcium / magnesium for taste — a light remineralization compared with the full alkaline-mineral stage on RO systems. That addition does not expand the certification; the added coverage comes from the NSF/ANSI 401 certification. PFAS, fluoride, and hexavalent chromium are not covered by this model.

The PFM400H is the most heavily certified PUR model and one of the most heavily certified faucet-mount filters on the consumer market at this price. It carries NSF/ANSI 42 + 53 + 401 coverage spanning chlorine, taste-and-odor, nominal particulate Class I, asbestos, chlordane, lead, mercury, toxaphene, VOCs, and 15 NSF/ANSI 401 emerging contaminants. The gap relative to the brand's broader '99% of contaminants' marketing is PFAS (PFOA/PFOS) and fluoride — even the most heavily certified PUR model does not carry NSF/ANSI P473 PFAS certification or any fluoride claim. For buyers whose main concern is PFAS or fluoride, the PUR lineup is not the right format; RO systems carry certified fluoride reduction, and select pitcher / countertop models from other brands carry PFAS certification.

The PFM800V's certification matches the PFM400H — the same NSF/ANSI 42 + 53 + 401 coverage with the same PFAS and fluoride gap. The differences from the PFM400H are housing finish (premium stainless-steel vs the PFM400H's stainless-steel) and price ($80-$100 retail vs the PFM400H's $50-$70). The higher price reflects housing materials and looks, not any extra certification over the PFM400H.

The PFM350V is the entry-level chrome faucet-mount in PUR's lineup, and a clear example of how sister models within the PUR faucet-mount line hold different certifications. The PFM350V is certified to NSF/ANSI 42 + 53 only — chlorine taste-and-odor plus lead and mercury reduction. The step-up PFM400H / PFM800V / RF-9999 MineralClear line adds NSF/ANSI 401 emerging-contaminants certification (15+ pharmaceuticals, BPA, microplastics) for a $15-$30 premium over the PFM350V. Buyers should match the certified scope to their priority: chlorine + lead at the PFM350V tier; chlorine + lead + emerging contaminants at the PFM400H tier and above.
