ANN ARBOR, Mich. - NSF International has published an easy-to-use consumer guide to water filters that have been tested and certified by NSF International to reduce lead in drinking water. This guide also explains the NSF standards and the process by which NSF International verifies a filter’s ability to reduce lead in drinking water.

The guide lists the water filters certified by NSF International for lead reduction along with the proper replacement cartridge (element) that should be used with each system. It includes information about the different types of NSF certified water filtration systems to help consumers know which system best fits their home or business. Additionally, the guide includes information about the importance of replacing filter cartridges (elements) and NSF International’s robust testing and certification process.

IMPORTANT: NSF International would like to remind everyone using NSF certified water filters that it is important to change the filter regularly, according to the manufacturer’s recommended filter capacity, in order for the filters to continue to reduce lead and other contaminants for which they are certified.

Consumers can email with any questions about water filters NSF certified for the reduction of lead.
