Drinking Water Treatment Units (NSF/ANSI Std. 42, 44, 53, 55, 58, 62)

NSF has served the point-of-use, point-of-entry Drinking Water Treatment Unit (DWTU) industry since 1968. NSF was asked then by the state drinking water administrators, and later by the USEPA, to develop consensus standards and certify health and aesthetic contaminant reduction claims for DWTUs.

These Standards have become important to manufacturers around the world as they seek entrance into this growing market. In 1996, NSF became a World Health Organization Collaborating Center for Drinking Water Safety and Treatment, which positions NSF Standards and NSF Certified products to be embraced around the world.
