How NSF International Evaluates Products that are Manufactured by Water Treatment Companies

Water Treatment Companies

NSF certification is highly sought after by water treatment companies that seek an authoritative stamp of approval for their products. NSF International, which was founded in 1944 as the National Sanitation Foundation, offers independent evaluation and certification for a wide array of consumer products that have a direct bearing on human health and environmental sustainability. The NSF certification mark is your assurance that a product has undergone rigorous laboratory testing and that its claims have been objectively verified by one of the most highly respected independent certification organizations in the world.

Water treatment companies that seek NSF certification for their products have their work cut out for them. NSF International devises strict product standards for both point-of-use (POU) and point-of-entry (POE) water treatment systems for the home. Because water quality is so important to consumers, NSF International goes to great lengths to ensure that water treatment products actually do as they are advertised. The seven POU/POE performance standards that NSF International has developed address a wide array of water treatment technologies available to today’s consumers, including drinking water purifiers, water softeners, ultraviolet (UV) filters, and more. Each standard sets the minimal requirements for certification for each applicable product category. Testing for each submitted product is performed inside of the world’s largest POU/POE testing facility and is overseen by a dedicated NSF project manager. NSF has a staff that is comprised of expert toxicologists, chemists, engineers, and microbiologists who make sure that only the most effective products receive NSF certification.

For more information, please contact RainSoft. RainSoft is one of the preeminent residential water treatment companies in the world and offers a number of products that have earned the NSF certification label.
