NSF developed its first drinking water treatment standard in 1973. Today, we test to seven point-of-use/point-of-entry (POU/POE) drinking water treatment standards and have certified thousands of systems and components. The NSF POU/POE standards address the wide array of drinking water treatment technologies on the market today, including adsorptive medias, ion exchange, reverse osmosis, ceramic filters, pleated filters, ultraviolet (UV), distillation, reduction-oxidation (redox), shower filters and more. Each NSF standard sets thorough health requirements and performance criteria for specific types of products. Contaminant reduction claims can be certified under each standard and can vary according to each water treatment technology capability.
Systems that utilize more than one treatment technology may be certified under multiple standards. Filtration Three NSF standards cover filtration systems: NSF/ANSI 42, NSF/ANSI 53 and NSF/ANSI 401. NSF/ANSI 42: Drinking Water Treatment Units - Aesthetic Effects NSF/ANSI 42 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste, odor and particulates) that may be present in public or private drinking water. The scope of NSF/ANSI 42 includes material safety, structural integrity and aesthetic, non-health-related contaminant reduction performance claims. The most common technology addressed by this standard is carbon filtration. NSF/ANSI 53: Drinking Water Treatment Units - Health Effects NSF/ANSI 53 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs) and MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water. The scope of NSF/ANSI 53 includes material safety, structural integrity and health-related contaminant reduction performance claims.

NSF/ANSI 244: Supplemental Microbiological Water Treatment Systems – Filtration NSF/ANSI 244 establishes minimum requirements for the reduction of microorganisms using mechanical filtration devices for supplemental treatment of microbiologically safe drinking water. Mechanical filtration devices covered by this standard are intended for use only on water supplies that have been treated to public water system standards or that are otherwise determined to be microbiologically safe, and are only intended for protection against intermittent incursions or accidental microbiological contamination of otherwise safe drinking water. The scope of NSF/ANSI 244 includes material safety and structural integrity, similar to other NSF/ANSI drinking water treatment unit standards. Reduction claims under this standard include bacteria, viruses and cysts. NSF/ANSI 401: Emerging Compounds/Incidental Contaminants NSF/ANSI 401 addresses the ability of a water treatment device to remove up to 15 individual contaminants (listed below), which have been identified in published studies as occurring in drinking water. While not a public health issue, the contaminants covered in NSF/ANSI 401 have been detected in drinking water supplies at trace levels and can affect some consumers’ perception of drinking water quality.
(NSF/ANSI 401 also applies to reverse osmosis (RO) water treatment.) Prescription Drugs • Meprobamate: a compound found in anti-anxiety drugs. Contoh Progaram Untuk Menentukan Hpp Secara Sederhana Menggunakan Fox Pro there. • Phenytoin: an anti-epileptic drug.
