SHANGHAI – Several Kohler Carafe® water filter systems are the first products to earn NSF International certification to NSF/ANSI 58. On June 5, Mr. David Purkiss, on behalf of global public health organization NSF International, presented the NSF certification at Kohler (China) Investment Co., Ltd.’s new products launch ceremony. NSF certification verifies that the Kohler kitchen water filtration system has been tested and certified by NSF International against the total dissolved solids (TDS) reduction requirements detailed in NSF/ANSI 58: Reverse Osmosis Drinking Water Systems, an American National Standard for drinking water treatment units. The first products to earn certification to NSF/ANSI 58 are the Kohler kitchen water filtration systems Carafe® series, models KP040, KP050, RO400-A,RO400-C, RO400-D, RO400-E, RO40-L and RO400-X.
This event was held during Kitchen & Bath China 2018, one of the largest events in Shanghai focusing on the kitchen and bath segment. The conference was attended by dozens of industry manufacturers, experts and media.
“In order to get NSF certification, Kohler has passed a stringent review, including strict testing to the relevant recognized standards, unannounced inspection at the manufacturing facility and periodic re-testing to verify our continuous compliance with NSF certification requirements,” said Mr. Ted Chen, Managing Director of the Purification Division at Kohler China. “Both Kohler and NSF International have done a lot of work during the certification process, which provides consumers confidence in the quality and safety of their drinking water. This is what makes the stringent and lengthy process of testing and certification worthwhile.”
“NSF International continues to protect and improve public health by certifying products worldwide that help improve the quality of drinking water,” said David Purkiss, Vice President of Water Systems at NSF International. “NSF’s certification to NSF/ANSI 58 means consumers now have a verified solution to reduce total dissolved solids (TDS) in their drinking water.”
To earn NSF International certification, water treatment systems, including water filters, must undergo extensive testing to confirm that they meet the strict material safety and structural requirements of NSF/ANSI 58, an American National Standard for drinking water treatment units. In addition to verifying that the system is structurally sound, NSF verifies that:
- The contaminant reduction claims, such as TDS reduction, shown on the label are true.
- The system does not add anything harmful to the water.
- The product labeling, advertising and literature are not misleading.
Certified products must be retested periodically and manufacturing facilities must be inspected every year, which ensures products continue to meet all requirements.
About NSF International:
NSF International (nsf.org) is an independent, global organization that writes standards, and tests and certifies products for the food, water, health sciences, and consumer goods industries to minimize adverse health effects and protect the environment. Founded in 1944, NSF is committed to protecting human health and safety worldwide. With operations in more than 175 countries, NSF International is a Pan American Health Organization/World Health Organization (WHO) Collaborating Center on Food Safety, Water Quality and Indoor Environment.
NSF International led the development of the American National Standards for all chemicals used to treat drinking water and materials/products coming into contact with drinking water in the U.S. Certification to these standards verifies products do not leach harmful levels of contaminants such as lead into water. In 1990, the government agency that regulates drinking water in the U.S. called the U.S. Environmental Protection Agency replaced its own drinking water product advisory program with these NSF standards. Today, most plumbing codes in the U.S. and some other countries require certification to NSF standards for pipes and plumbing components in commercial and residential buildings.
