PurityMap analysis · bottom line

The AquaTru certifications in a smaller carafe: lead, fluoride, arsenic V, nitrate and PFOA/PFOS with no installation.

Match factors
  • ✓ IAPMO-certified to NSF/ANSI 58, 53 and 42
  • ✓ No installation; fits renters
Watch-outs
  • – Filled by hand
  • – Needs counter space and a power outlet

Limitations and trade-offs

  • 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.
  • Smaller glass-carafe format than the AquaTru Classic.
  • 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.

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.
