In the last decade, interest in home water treatment products has grown tremendously. Unfortunately, it isn’t always easy for consumers to know whether or not a particular product will actually be as safe and effective as the manufacturer/ claims at reducing various contaminants from your water supply.

NSF has a long history of developing and running independent product testing programs. In fact, they are the leading independent tester of home water treatment products on the market today. With there state-of-the-art laboratories and highly skilled staff, they have the knowledge and expertise to effectively evaluate water treatment products, including:

• Filtration filters (i.e. carbon, charcoal, KDF, ceramic)
• Reverse osmosis systems
• Water softeners
• Distillation systems
• Ultraviolet disinfection products.

As an added assurance for consumers, NSF requires that all products meet annual re-certification requirements. Unannounced plant inspections and periodic retesting of all certified products are required of all NSF-listed companies. This unique requirement allows NSF to ensure that the products they certify continue to meet all stated requirements year after year.
