"Copper (as well as brass and other copper alloys), when used as building hardware, plumbing tube, utensils, item of daily use and as ions injected directly into potable water, is a significant deterrent to the contraction of disease by the reduction of bacteria and viruses in healthcare facilities. Copper is especially effective in controlling Legionella pneumophila, the bacterium responsible for Legionnaires’ disease." as quoted from an article under Heading - Copper Applications in Health & Environment Area by INNOVATIONS - the online magazine from Copper Development Association (CDA) at www.copper.org

Copper is a natural elemental that contains antibacterial benefits, therefore bacteria and other harmful substances cannot hope to survive on copper.In a study performed on, stainless steel and copper, it was shown that copper is extremely sanitary by comparison. Thanks to the antibacterial benefits of copper, a bacterium that is found on the copper will not live any longer than one to two hours. Common diseases causing bacteria, such as E-Coli, Streptococcus and the common flu viruses have trouble surviving on copper, which means that whatever germs your fingers bring to the sink, they won't survive for long if your sink is made of copper. This makes the copper sinks most sterile sinks.
