PurityMap analysis · bottom line

A certified gravity filter: lead, PFOA/PFOS and arsenic V reduction with no power or plumbing.

Match factors
  • ✓ NSF- and IAPMO-certified to NSF/ANSI 53
  • ✓ No electricity or plumbing
Watch-outs
  • – About 200 gallons per filter
  • – Batch filling

Limitations and trade-offs

  • PFAS coverage is PFOA and PFOS, not Total PFAS.
  • Arsenic claim is arsenic V only, and only for water at or below the tested arsenic level.
  • About 200 gallons per Nanomesh filter.
  • Treats the water you pour through it, not a whole tap.
  • Filled by hand in batches
  • About 200 gallons per filter
  • Takes counter space

No filter treats every water problem. This analysis does not replace household testing, installation requirements, or the manufacturer’s current performance data sheet.

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

Start from your water, not the product.

Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
