Product recordPurityMap analysisThis profile evaluates where the product record fits, what its listed technology can address, and the constraints a household should check before buying.
Match factors
- Extensive published lab testing
Watch-outs
- Not NSF/ANSI 53 certified for lead or PFAS
Assessment basis: Certification checked against the NSF, WQA and IAPMO registries (2026-09-23).
Which water problems is this relevant to?Each target in PurityMap’s evidence register for this product, with its state. Relevance starts with a documented water problem, then the treatment technology, then a product whose exact, current certification covers that target.
- Chlorine taste/odor Not established
- Lead Not established
- PFOA Not established
- PFOS Not established
- PFHxS Not established
- PFNA Not established
- PFHxA Not established
- PFBS Not established
- PFHpA Not established
- GenX Not established
A capability listed here does not mean that contaminant is present in your water. Find your water system before deciding what treatment is relevant.
Certification and claim scope
One row per target in PurityMap's evidence register. Eligible means a current certification record for this exact product covers that target, checked in the certifier's registry within the last 90 days. Not established always comes with the reason.

Not suitable for
- Treating every tap in the home
- A whole-home hard-water or scale problem
- All PFAS: its evidence covers only the compounds it names
Test first
- Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
- A tap test can confirm levels at your home before you choose treatment.
Installation, ownership, and maintenanceCapacity and upkeep are planning figures from the product record, not guarantees. Actual replacement timing depends on use, influent water, flow, and manufacturer instructions.
Limitations and tradeoffs
- Its lead and PFAS reduction is tested, not certified; choose an NSF/ANSI 53 certified filter when lead or PFAS is documented.
- Lower flow than whole-house
- Cartridge changes every few months
No filter treats every water problem. This analysis does not replace household testing, installation requirements, or the manufacturer’s current performance data sheet.
Manufacturer claims we could not verifyThese appear in manufacturer or retailer material but are not backed by a certification PurityMap could confirm. Treat them as unverified.
- Lead, PFAS and other health-contaminant reductions were tested by an independent lab (IAPMO New Jersey) to NSF/ANSI 53 protocols. The pitcher is not certified to NSF/ANSI 53.
