Many people are surprised to learn that heavy metals such as lead, mercury, nickel, and chromium can contaminate their water supply. These contaminants may come from corroded plumbing, industrial waste, and contaminated groundwater. Prolonged exposure to heavy metals is linked to serious health issues like kidney damage, neurological disorders, developmental problems, and even cancer (WHO, 2022, CDC, 2023).
Adding to this, chlorine, widely used as a disinfectant in municipal water supplies, brings its own set of problems. While it effectively kills harmful pathogens, it leaves behind a strong taste and smell, can irritate skin and eyes, and forms harmful byproducts like trihalomethanes (THMs) and haloacetic acids (HAAs)—both classified as possible carcinogens (EPA, 2023).
The Doulton KDF Filter uses Kinetic Degradation Fluxion (KDF) media, which consists of high-purity copper-zinc granules. This media triggers a redox reaction that effectively removes heavy metals, reduces chlorine, and inhibits bacterial growth within the filter. Additionally, it helps to control scale buildup, protecting appliances like kettles and coffee makers.
The KDF filter is an ideal choice for homes with aging pipes, high chlorine levels, or concerns about bacterial contamination. It works excellently as a pre-filter, extending the lifespan of the main ceramic filter by handling heavy metals and chemical contaminants upfront.
