FEDERAL, STATE AND INDUSTRY STANDARDS

  • US EPA (the federal organization responsible for our nation’s drinking water standards) DOES NOT test, approve, or endorse any water treatment system evaluation. Since there are no federal standards for drinking water treatment systems, EPA will refer consumers to NSF International to receive a listing of NSF certified drinking water treatment systems.
  • NSF - National Sanitation Foundation, a not-for-profit organization devoted to developing testing protocols and administering programs relating to products and services that affect public health, has developed a drinking water treatment unit program and protocols for testing water treatment systems which states and industry have adopted.
  • Two standard protocols for filter devices are NSF Standard 42, Aesthetic effects (taste, odor, color, appearance) and NSF Standard 53, Health Effects.
  • NSF certification not only encompasses contaminant reduction claims, it also makes sure the system is not adding anything harmful to the water, that the system is structurally sound, advertising, literature and labeling are not misleading and the materials and manufacturing process does not change. NSF certification is a symbol you and your family can rely on for assurance that products have met strict public health and performance standards. For more information on NSF, click the links on this page or call 1-800-NSF-MARK.
  • In addition, some states have established their own set of standards and product/service registration process. These states include California, Wisconsin, and Iowa
