Match factors
- No electricity or plumbing
Watch-outs
- No verified certification
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.
- Unspecified contaminant reduction Not established
- Lead 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
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
- Not certified for PFAS unless the specific element lists NSF/ANSI 53 for PFOA/PFOS, so check the model.
- Slow gravity flow
- Takes counter space
- Refill by hand
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.
- The manufacturer claims NSF/ANSI 42 and 372 certification, but this model is not found in the NSF, WQA or IAPMO listings.
- Lead reduction is not certified.
