Silver Fact Sheet

Biologically, silver is a nonessential, non-beneficial element to humans. There are no scientific studies to show adverse health due to its presence in drinking water from natural sources. However, because of its bactericidal abilities, silver is used as a water bacteriostat in carbon containing water filters. The silver is deposited onto the carbon granules to inhibit the growth of bacteria on the surfaces of these carbon particles. Such filters tend to leach out trace levels of silver into the effluent water. At anticipated concentrations, the ingestion of silver has no documented detrimental effect on humans.
