As the world leader in testing and certification of drinking water treatment technologies, NSF helps manufacturers around the world prove that their products meet structural and safety requirements, as well as contaminant reduction claims.

Our certification and testing services apply to a wide range of water treatment and filtration systems, including:

  • General water filtration devices
  • Reverse osmosis systems
  • Distillation systems
  • Shower filters
  • Ultraviolet (UV) systems
  • Water softeners

Certify your products to NSF/ANSI 42, NSF/ANSI 53 or many other product standards to meet local requirements for health and safety.

Although product certification in the water treatment industry is often voluntary, manufacturers receive many benefits from working with NSF experts, including:

  • A dedicated account manager who stays with you every step of the way
  • Quick testing in world-class labs, so you can meet your business goals
  • Use of the NSF mark, which broadens market access and ensures consumer peace of mind

An independent study conducted on behalf of NSF found that 75% of consumers would purchase a product with a certification mark over one without. All certified filtration technologies are listed on NSF’s website, expanding your product’s visibility to consumers.
