What Is NSF Certification?
NSF Certification is an assurance of quality, performance, and integrity. It states that:
• The system meets the contaminant reduction claims of the manufacturer;
• The system is not adding anything harmful to the water;
• The system is structurally sound;
• Advertising, literature, and labeling are not misleading; and
• The materials and manufacturing process do not change.
From extensive product testing and material analyses to unannounced plant inspections, NSF undertakes a complete evaluation of every aspect of a product’s development before it can earn certification. NSF Certification is not a one-time activity – NSF requires regular on-site inspections of manufacturing facilities, as well as periodic retesting of products against the most current national standards. For the consumer, this allows NSF certified products to be purchased and used with confidence.
The NSF Difference
Some companies tout their products as “tested according to NSF standards” or “meets NSF testing requirements,” but unless they have been officially NSF certified, such claims are not a guarantee of quality. Manufacturer-driven testing, even to NSF’s standards, does not equate to the continual process of inspection and testing that comes with NSF Certification. NSF assures quality and integrity because NSF does not let the manufacturer affect the testing process, and NSF does not stop the testing and evaluation process. Multipure products are NSF certified to demonstrate the quality and integrity of their performance.
