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
- PFAS coverage is PFOA and PFOS, not Total PFAS.
- Its arsenic claim is arsenic V; arsenic III may need pre-oxidation.
- Treats the water you pour into it, not a whole tap.
- The Smart and Alkaline variants are not on these listings.
- Sits on the counter and is filled by hand
- Needs counter space and a power outlet
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.
- An IAPMO NSF/ANSI 401 certificate (18731) exists, but its claims were not reviewed, so no NSF/ANSI 401 reduction is listed here.
