NSF Mark

The NSF mark is specific to the type of product it appears on — from dietary supplements, to water filters and dishwashers to plumbing components, pool equipment and more.

Products bearing an NSF certification mark meet all standard requirements, including product testing and regular inspections to verify products continue to comply with the standard.

The NSF mark:

  • Provides assurance that a product was impartially reviewed to established standards or guidelines
  • Confirms that product labeling and claims have been objectively verified by a trusted third party
  • Differentiates a product from the competition, offering a market advantage
  • Demonstrates an organization’s commitment to quality, compliance and safety
  • Is backed by a team of professionals dedicated to public health and safety operating in more than 180 countries
