This document contains exactly the same information as ANSI/NSF 53-2002 and both addendums from 2002, but it has been reformatted per NSF's lab personnel to make it more user friendly. If you have these three documents, there is no need to purchase this document unless you want the user-friendly version.
The point-of-use and point-of-entry systems addressed by this Standard are designed to be used for the reduction of specific substances that may be present in drinking water (public or private). These substances are considered established or potential health hazards. They may be microbiological, chemical, or particulate (including filterable cysts) in nature. It is recognized that a system may be effective in controlling one or more of these contaminants, but it is not required to control all. Activated carbon filter systems covered by this Standard are not intended to be used with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
