The standard measures the filtration efficiency of air filters used in both commercial and residential applications. Efficiency is rated based upon the removal of respirable particles in the size range of 0.3 to 10 microns, providing for a health-based criteria. The goal of this cooperative agreement is to facilitate the production of credible, third-party performance verification data. Qualification includes review and approval of quality assurance practices and participation in inter-laboratory testing. This is the first of a series of services that NSF International is initiating to meet the needs of the many industry sectors that have an impact on indoor air quality and associated health effects.
Manufacturers now have options for expediting and fulfilling their testing and certification needs.
NSF International is privileged to work with all code organizations in fulfilling its mission to promote public health safety. The NSF Protocol was developed with cooperation from the U.S. Environmental Protection Agency, the U.S. Virgin Islands and Bermuda. Testing involves extractions to determine whether roofing materials contribute unhealthful levels of contaminants into collected water before and after exposure to simulated tropical conditions. A significant portion of the population of the U.S. Virgin Islands, Bermuda and many developing countries depend on rainwater as a primary source of drinking water. Products meeting the requirements of the NSF protocol are permitted to display the NSF Certification Mark.
