We submit our filters for third party testing at certified ANSI/NSF laboratories such as those of IAPMO (International Association of Plumbing and Mechanical Officials). Testing is carried out in accordance with ANSI/NSF standards and protocols such as ANSI/NSF STD 42, 53, 401, 244 or P231. We test for the entire rated life of the filter to ensure that the target performance is sustained.
During the COVID-19 crisis, we have been forced to publish some internal test data while third-party certified laboratory results are delayed.
