Claims listed by IAPMO R&T

Checked 2026-09-30. Directory edition: Public active certificates; revisions are listed with each system. These are the exact named brand and filtration systems, not certification for every option on this page. A capacity applies to its named system; it does not apply to mechanical filtration claims.

The manufacturer sheet and directory are separate records and can list different claims. Only claims in the directory entries below are attributed to IAPMO R&T here; an omitted claim remains unverified in this directory snapshot.

Performance evidence for each option

A compatible fit does not transfer the OEM reduction claims. Each option needs its own exact brand, cartridge and system evidence. Unverified means evidence is missing here, not that a filter failed a test.

What each MWF option claims

7 of 31 listings state a claim

These are claims in listing titles and stored listing fields, not independently verified performance results. Standard numbers do not establish every contaminant a filter reduces. Check the exact model, certifier and reduction claims on its performance data sheet. NSF/ANSI 372 concerns lead content in materials, not lead reduction in drinking water. Read the certification guidance.
