"Uses of Silver for Water, Food, Hygiene
Silver's antibacterial properties have been applied for thousands of years, long before the discovery of microbial organisms, because silver containers and coins were known to prevent spoilage of liquids. Today, a silver coating prevents bacterial build-up in carbon-based water filters, while silver ions in water purification systems carry oxygen that oxidizes and kills microbes. Silver-copper ions can even replace corrosive chlorine to sanitize pools and tanks.
The antimicrobial properties of silver that make it useful to medicine and water purification are now being applied in food and hygiene. Nanosilver coatings are applied to food packages and refrigerators. And many new consumer products, such as washing machines, clothing, and personal hygiene products tout the benefits of antibacterial silver. "
