What Is NSF Certification? 2021-01-12
NSF Certification International (NSF International) was established in 1944 as an independent, non-profit non-governmental organization. NSF is an authority in the field of public health and safety, specializing in the development of standards, product testing and certification services in the fields of public health, safety and environmental protection.

NSF is the designated collaborating centre of the World Health Organization (WHO) for food safety and drinking water safety and treatment. Products that have been tested by NSF and meet NSF standards are authorized to use the NSF logo. Therefore, products that have been authorized to carry the NSF logo mean that the product has been confirmed in the following aspects:
1. It can achieve the ability of removing impurities marked in the product manual
2. The material of the product will not add pollution to the water in the process of water treatment
3. Meet the design and production process requirements
4. The product has no structural and functional defects
5. The certification standards shown in the advertisements, sample materials and marks of the products are true and accurate

NSF requires that if a company wants to print NSF logo on its products, it must comply with the strict requirements of NSF certification and authorization. These requirements include initial and periodic testing and evaluation, and even the use of surprise inspections. If it is found that the logo is misused or the product does not comply with the requirements, NSF may take measures to impound and seal up the products and inventory goods, or even destroy the unqualified products and put them on the blacklist, as well as take recall, legal action, public notification, disqualification or other severe actions. NSF represents the interests of all parties. It will regulate the behavior of insiders, consumers and manufacturers, supervise the implementation of policies and the authority of certification.
