(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
International to receive a listing of NSF
certified drinking water treatment systems.
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
standard protocols for filter devices are NSF Standard 42, Aesthetic
effects (taste, odor, color, appearance) and NSF Standard 53, Health
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,

addition, some states have established their own set of standards and
product/service registration process. These states include California,
Wisconsin, and Iowa
