Who Is NSF International?

NSF International was founded in 1944 as the National Sanitation Foundation to help standardize sanitation and food safety at a time when the United States had no national sanitation standards. As NSF expanded services beyond sanitation and became a global public health and safety organization, we changed our name to NSF International in 1990.

What Is NSF Certification?

Millions of people take the safety of their food, water and consumer products for granted on a daily basis. Why? Because of three letters: NSF. NSF certification is your key to making sure that the products you use meet strict standards for public health protection.

Scrub Club®

Launched in 2007, NSF International’s Scrub Club^® was the first of its kind – a fun, interactive and educational website that teaches children the proper way to wash their hands.
