NSF and ANSI Standards

* In considering POU water systems for your employees – Ask for system certifications

Here are NSF/ANSI standards met by Aquaprix Point of Use Water purification systems:

NSF/ANSI Standard 42: Drinking Water Treatment Units – Aesthetic Effects

Overview: This standard covers point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste and odor, and particulates) that may be present in public or private drinking water.

NSF/ANSI Standard 53: Drinking Water Treatment Units – Health Effects

Overview: Standard 53 addresses point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.

NSF/ANSI Standard 55: Ultraviolet Microbiological Water Treatment Systems

Overview: This standard establishes requirements for point-of-use (POU) and point-of-entry (POE) ultraviolet systems and includes two optional classifications.

NSF/ANSI 55, Class A systems (40,000 uw-sec/cm2) are designed to disinfect and/or remove microorganisms from contaminated water, including bacteria and viruses, to a safe level.

NSF/ANSI 55, Class B systems (16,000 uw-sec/cm2) are designed for supplemental bactericidal treatment of public drinking water or other drinking water, which has been deemed acceptable by a local health agency.

NSF/ANSI Standard 58: Reverse Osmosis Drinking Water Treatment Systems

Overview: This standard was developed for point-of-use (POU) reverse osmosis (RO) treatment systems. These systems typically consist of a pre-filter, RO membrane, and post-filter. Standard 58 includes contaminant reduction claims commonly treated using RO, including fluoride, hexavalent and trivalent chromium, total dissolved solids, nitrates, etc. that may be present in public or private drinking water.

NSF/ANSI Standard 61: International Standard for Drinking Water Additives, Section 8

Overview: This standard establishes minimum health effects requirements for the chemical contaminants and impurities that are indirectly imparted to drinking water from products, components, and materials used in drinking water systems. This Standard does not establish performance, taste and odor, or microbial growth support requirements for drinking water systems products, components, or materials.

NSF Protocol P231

NSF Protocol P231 addresses systems that use chemical, mechanical, and/or physical technologies to filter and treat waters of unknown microbiological quality.  This protocol is also known at the EPA purifier standard for non-potable water.
