The NSF Mark, well respected by public health officials, retailers, and consumers, is recognized as a symbol of product quality and integrity. Through the years, the NSF Mark has helped thousands of manufacturers get to market faster, expand into new markets, and get their products accepted more easily.
While we distinguish ourselves due to our thorough product evaluation, we've made the process simple and efficient for clients. By assigning a dedicated NSF project manager, you will have one single point of contact to guide you through the process, overseeing your certification project every step of the way.
For more in-depth information on the certification process, review the details below:

In addition to NSF's responsibilities for the development and maintenance of Standards 60 and 61, NSF developed a certification program based on Standards 60 and 61 which includes unannounced factory audits, product testing, and evaluation of products and materials. All information disclosed to NSF is held in strict confidence.
NSF toxicology staff first reviews the product/material information submitted by a manufacturer. Typically, additional material or ingredient information is required and this information is requested in order to determine all potential contaminants to drinking water. This is an important step, because to properly evaluate a product or material for health effects, complete information about the formulation and impurities associated with each of its ingredients must be known by the certifying agency.
A factory audit is then scheduled and performed by trained NSF auditors. During the audit, formulations and suppliers are verified, QA/QC records are audited, and the product/material is sampled for testing at NSF.
The sampled product/material is tested according to the protocols outlined in each of the standards. Following laboratory testing, contaminant concentrations are "normalized" or converted to at-the-tap concentrations and compared to the standard's maximum allowable level (MALS). If the results are acceptable, NSF and the manufacturer enter into a contractual agreement and the product is certified and Listed by NSF. The NSF authorized formulations are retained at the product facilities. Deviations from the authorized formulation are not permitted without advance written notice to, and acceptance by, NSF.
After the initial certification, production facilities are audited unannounced and certified products are tested and/or evaluated on a periodic basis (typically annually), to ensure continued compliance with the requirements of the standard, and that the manufacturer continues to operate in accordance with NSF's general and program specific certification policies.
The listings are updated daily and available online by clicking "Product Database" above. These listings are a key document for anyone involved in the specification of drinking water products.
Communities that treat their drinking water supply with NSF Certified drinking water treatment chemicals can assure their residents that these chemicals do not contain contaminants that will cause adverse health effects. Consumers should contact their local water utility to ensure that the chemicals used to treat their water are certified by NSF to NSF/ANSI Standard 60.
Consumers can also be assured that the materials used in plumbing products will not contribute contaminants to their drinking water if these products are NSF Certified to NSF/ANSI Standard 61. Consumers should look for the NSF Mark on faucets and other plumbing products that they purchase to install themselves, or request that their plumber use only NSF Certified drinking water system components. Search our certified product database for a list of NSF Certified products.
Regulators can be assured that products certified to NSF/ANSI Standard 60 and 61 meet strict health effects requirements. NSF staff is always willing to verify the NSF Certification of products, and provides free copies of NSF Listings to regulators.
