Clean Sip patented state of the art technology is a combination of three micro filters, activated charcoal and a patented, high purity metal alloy. The alloy consists of two dissimilar metals, that once wet, create an electrostatic charge that attracts contaminants and electroplates them onto the media through a process called electro-chemical oxidation reduction. This reduces such heavy metals as lead mercury, hydrogen suilphide, aluminum, arsenic, cadmium, chromlum, and barlum. In addition to chlorine, fluoride, glardia, e-coli, algae, fungus, scale, and sediment. This electro-chemical oxidation, reduction process is scientifically proven to effectively remove contaminants from your water.
