The NSF mark is your assurance that the product has been tested by one of the most respected independent certification organizations in existence today. It is valued by consumers, manufacturers, retailers and regulatory agencies worldwide.
The NSF certification mark on a product means that the product complies with all standard requirements. NSF conducts periodic unannounced inspections and product testing to verify that the product continues to comply with the standard.
NSF’s programs include testing and certifying drinking water treatment products and water filters, commercial food service equipment and a wide array of consumer products such as bottled water, nutritional supplements, private label goods, personal care items and home appliances (washers, dryers and dishwashers).
