NSF International has published a simple guide for consumers that lists certified water filters that reduce lead in drinking water, in response to the Flint water problem.
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.
In addition, the guide includes information about the importance of replacing filter cartridges (elements) and NSF International’s robust testing and certification process. The guide will be updated when new products have been certified. To obtain a copy of the guide, use the enquiy form on this page.
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.
