© CPA Consumer Tool for Identifying X/E!Z^s Point-of-Use and Pitcher Filters Certified Environmental Protection r» i ¦ i • » i • m - Agency to Reduce Lead in Drinking Water Point-of-Use Filters Point-of-use, or POU, water filters remove impurities from drinking water at the point that it is actually being used. Although there are others, the POU filters covered in this document are those that are used in filtration systems that are attached directly to water faucets or those inserted into refrigerators for water and ice dispensers. Why is certification important for water filters? Consumers can increase their level of confidence by purchasing POU and pitcher filters that have been evaluated by an accredited third-party certification body or bodies for drinking water lead reduction to 5 parts per billion (ppb) or less and particulate reduction (Class I) capabilities. How do I know if a filter is certified to reduce lead? There are several American National Standards Institute (ANSI) accredited third-party certification bodies that evaluate POU and pitcher filters for lead reduction in drinking water. They each have unique certification marks (registered trademarks) that are used on certified products. Faucet Filter Device Refrigerator Filter Pitcher Filters Pitcher water filters remove impurities from drinking water and are those that are inserted into water pitchers and bottles. Certification bodies require their mark and a statement indicating testing against NSF/ANSI Standard 53 along with a claim of lead reduction. It is recommended that you also look for filters tested against NSF/ANSI Standard 42 for particulate reduction (Class I). Certification Marks Below are the ANSI accredited third-party certification bodies' approved certification marks and the text that indicates a filter has been evaluated for lead reduction capabilities. Some filters can be certified by more than one certification body and have multiple certification marks. See page 2 for information on where to find marks and claims of reduction. a- :0 i:. uIs-i ''."rT^uSr.. 1^'::! .r.s:il"i L i" i \t 0®:v?:®;l NSF product listing directory info.nsf.org/Certified/DWTU/ 0?i!;lr!0 i .•«-!

June 2024 (Update to EPA/600/F-18/335) ------- Certification Marks, Standards Text, and Claims of Reduction on Filter Packaging Certification marks (page 1) can be found on the filter packaging, the filter, or on the smallest container in which the filter is packaged. Examples of certification marks, NSF/ANSI Standards 42 and 53 text, and claims of lead reduction and particulate reduction (Class I) as found on product packaging are shown below.
