What Is An NSF Certification? 

Millions of people take the safety of their food, water, and consumer products for granted daily. Why? Because of three letters: NSF. NSF certification is your key to ensuring that the products you use meet strict public health standards.

Choosing a product certified by NSF confirms the company complies with strict NSF testing, standards, and procedures. From extensive product testing and material analyses to unannounced plant inspections, every aspect of a product’s development is thoroughly evaluated before it can earn our certification. Most importantly, NSF certification is not a one-time event but involves regular on-site inspections of manufacturing facilities and regular re-testing of products to ensure that they continue to meet the same high standards required to maintain certification over time.
If for any reason a product fails to meet one or more certification criteria, NSF will take enforcement actions to protect you, including product recall, public notification, or de-certification. Products that earn NSF certification are said to be “NSF certified” or “NSF listed” and display the applicable NSF certification mark to show that they have been tested by one of today’s most respected independent product testing organizations.
