Standards applied for testing and certification

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

Filters are certified to reduce aesthetic impurities such as chlorine and taste/odor. These can be point-of-use (under the sink, water pitcher, etc.) or point-of-entry (whole house) treatment systems.

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

Filters are certified to reduce a contaminant with a health effect. Health effects are set in this standard as regulated by the U.S. Environmental Protection Agency (EPA) and Health Canada. Both standards 42 and 53 cover adsorption/filtration which is a process that occurs when liquid, gas or dissolved/suspended matter adheres to the surface of, or in the pores of, an adsorbent media. Carbon filters are an example of this type of product.

NSF/ANSI 401 : Emerging Compounds / Incidental Contaminants

Treatment systems for emerging contaminants include both point-of-use and point-of-entry systems that have been verified to reduce one or more of 15 emerging contaminants from drinking water. These emerging contaminants can be pharmaceuticals or chemicals not yet regulated by the EPA or Health Canada.

NSF/ANSI 372 : Drinking Water System Components

Lead Content is an American National Standard that establishes a standardized methodology for the determination and verification of product compliance to minimize lead contaminants. NSF/ANSI 372 is consistent with the United States Safe Drinking Water Act (SDWA) and its lead-free plumbing requirements, as well as the requirements of individual U.S. states such as California. NSF/ANSI 372 serves as a basis to establish conformance with these regulations.

NSF/ANSI 372 addresses lead content only. Typically, regulations also require conformance to an extraction or leaching test standard. For most products, this means NSF/ANSI 61. For point-of-use and point-of-entry water treatment products, this means NSF/ANSI 42, 44, 53, 55, 58 or 62.

The NSF/ANSI 372 standard includes:

• A maximum weighted lead content requirement of 0.25 percent (0.2 percent for solders and fluxes)

• A formula for calculating the weighted average lead content of each product prior to testing

• Specific procedures for testing products for lead content
