NSF International is a global, independent, public health and safety organization with a mission to protect and improve human health.<\/p>\n<ul>\n<li>NSF has created standards for testing and certifying filtration levels. Manufacturers pay the NSF to test their filters. If they meet the requested standard they can use the NSF certification in their marketing materials. Because of the cost of testing many aftermarket filters are not certified. This is much more common among name brand products (sometimes called OEM: original equipment manufacturing).<\/li>\n<li>NSF standards have been created in conjunction with The American National Standards Institute. ANSI is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States.<\/li>\n<\/ul>\n<p><a href=\"http:\/\/www.filtersfast.com\/blog\/wp-content\/uploads\/2018\/06\/apartment-architecture-cabinets-373548.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-19527 aligncenter\" src=\"http:\/\/www.filtersfast.com\/blog\/wp-content\/uploads\/2018\/06\/apartment-architecture-cabinets-373548-300x196.jpg\" alt=\"\" width=\"300\" height=\"196\" srcset=\"https:\/\/blog.filtersfast.com\/blog\/wp-content\/uploads\/2018\/06\/apartment-architecture-cabinets-373548-300x196.jpg 300w, https:\/\/blog.filtersfast.com\/blog\/wp-content\/uploads\/2018\/06\/apartment-architecture-cabinets-373548-768x503.jpg 768w, https:\/\/blog.filtersfast.com\/blog\/wp-content\/uploads\/2018\/06\/apartment-architecture-cabinets-373548-1024x670.jpg 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p><strong><u>NSF\/ANSI 42: Aesthetic Effects<\/u><\/strong><\/p>\n<ul>\n<li>NSF\/ANSI 42 is one of the two main NSF standards that set the benchmark for evaluating safety and integrity of residential water filters.
