NSF International is an independent, accredited organization that develops standards, and tests and certifies products and systems. They provide auditing, education and risk management solutions for public health and the environment. Water safety and management, which encompasses pools and spas, are a large part of its focus.

Each year, NSF produces a supplement to Aquatics International's September issue to inform and educate the aquatics industry with updates to relevant codes and standards, all in an effort to create cleaner, safer pools.
