Why is NSF important?

NSF is the leading global, third-party testing and certification organization for products that come in contact with drinking water. Third-party, independent certification is important for consumers when purchasing drinking water filters because it is the only objective way to validate a manufacturer’s product health and performance claims. The NSF certification process gives confidence to consumers by allowing them to confirm that the product performs as claimed.
