The Certification

ISO/IEC 17025 laboratory testing Tested by an IAPMO R&T–recognized laboratory accredited to ISO/IEC 17025.

What Certification Means for You

Plenty of filters claim performance. Very few prove it to an accredited body.

Verified by a third party, not by us

Anyone can claim performance. IAPMO R&T is an accredited certification body — our claims are checked by people with no stake in the sale.

Performance you can look up

Every certified model's flow rate, filtration capacity, and reduction claims are public record — linked from this page, hosted by IAPMO, not by us.

Safe materials, not just effective filtration

Certification covers materials safety and structural integrity — and the systems are separately certified lead-free under NSF/ANSI/CAN 372, so what the system is made of is held to the same standard as what it removes.

Audited continuously

IAPMO re-inspects our factory and quality system on an ongoing basis. Certification lapses if the product stops matching what was tested.
