Performance testing and certification by NSF and ANSI sorts world-leading water dispensers from the also-rans. These two organisations set and regulate national and international safety standards, and Waterlogic has achieved all the following standards:
NSF/ANSI Standard 61:
This is the standard for drinking water system components. It ensures no harmful contaminants could leach or migrate from the product/material into the drinking water.
Models with NSF/ANSI Standard 61 are WL 1000 GF, WL 2000 and WL 2500.
NSF/ANSI 55 Class A
This is the standard for ultraviolet microbiological water treatment systems. Waterlogic Firewall is certified as a Class A system (40,000 uwsec/cm2) designed to disinfect and/or remove microorganisms from contaminated water, including bacteria and viruses, to a safe drinkable level. Which it does with pure genius.
This is the standard for microbiological water purifiers. Water coolers with this certification meet the exacting health and sanitation standards of the U.S. Environmental Protection Agency. Waterlogic machines have that badge, of course.
