Test Results Overview
The summarized results prominently highlight the filter's effectiveness against Legionella bacteria. Below, you will find access to the original test reports and protocols, along with details on the antibacterial treatments applied to handles and showers to inhibit bacterial growth on surfaces.
12-Month Comprehensive Evaluation
Mentor Water Technologies' filter is the only Hollow Fiber filter globally that has been tested continuously over 360 days with the same filter samples. The testing schedule included evaluations on day one, followed by subsequent checks on day 30, 60, 90, 120, 180, and 360, adhering to the Microbial Reduction Protocol based on the ASTM Standard F838-05. This standard measures the bacterial retention capabilities of membrane filters used in liquid filtration. All assessments were conducted by the VITENS laboratory in the Netherlands.
