About NSF

Manufacturers, regulators and consumers look to NSF International for the development of public health standards and certification programs that help protect the world’s food, water, consumer products and environment. Our mission is to protect and improve global human health. As an independent, accredited organization, our standards group facilitates the development of standards, and our service groups test and certify products and systems. We also provide auditing and risk management solutions for public health and the environment.

Founded in 1944 as the National Sanitation Foundation, we changed our name to NSF International in 1990 as we expanded our services beyond sanitation and into global markets. The letters in our organization's name do not represent any specific words today.
