Although tap water that meets federal and state standards is generally safe to drink, threats to drinking water quality in the United States still exist. Outbreaks of drinking water-associated illness and water restrictions during droughts demonstrate that we cannot take our drinking water for granted.

DPD’s Healthy Drinking Water Program was created to reduce the spread of drinking water-associated illness by working with partners to:

• develop evidence-based prevention recommendations and health communication materials,
• enhance surveillance for drinking water-associated illness,
• support illness outbreak investigations and emergency responses, and
• support epidemiologic and laboratory research on drinking water issues.

Patented KDF process media consist of high-purity copper-zinc formulations. These substances exchange electrons or bond with chlorine and other metals contained in the water to create harmless substances.

Through this basic chemical process known as redox (oxidation/reduction), KDF process media work behind the scenes to rid your water of chlorine, lead, mercury, iron and hydrogen sulfide. The redox reaction also inhibits the growth of bacteria, algae, and fungi. As an added benefit, KDF media reduce lime scale, mold, and fungi in your tub or shower.

KDF process media are completely safe. KDF media meet EPA and Food and Drug Administration standards for levels of zinc and copper in potable water, so the process is not toxic and does not cause any adverse side effects. KDF media are certified by the NSF Standard 61 and Standard 42 — Your assurance that they meet public safety standards.

KDF media are environmentally sound and 100 percent recyclable, but refer to the instructions enclosed with your filter or system for proper disposal, as different manufacturers combine KDF process media with other filtration technologies.
