NSF NSF (National Sanitation Foundation) is an independent agency that certifies that Waterfilters.net products have passed a series of stringent, independent tests. NSF is widely recognized for its scientific and technical expertise the health and environmental sciences. Its staff includes engineers, chemists, toxicologists, microbiologists, and environmental health professionals with broad experience in both public and private organizations.


What does NSF Certification mean?
For a drinking water treatment system to become NSF Certified, it must meet five basic requirements:
  • Contaminant reduction claims are true.
  • The system does not add anything harmful to the water.
  • The system is structurally sound.
  • The advertising, literature and labeling are not misleading.
  • The materials and manufacturing process used do not change, meaning consistent product quality over time.

NSF Certification programs benefit regulators, consumers, and manufactures. The regulatory and consumer groups have the assurance that a credible, objective, independent third-party, widely recognized by public health officials, has actually tested and verified that certified products comply with specific standards. By participating in NSF Certification programs, with required testing, retesting and inspection/audits by a third party, a manufacturer demonstrates the capability to produce products complying with recognized standards. The standards specify the requirements for the products, and many include criteria relating to materials, design, construction and performance.
