Because silver has an adsorption effect on microorganisms in the liquid, and the microorganisms are adsorbed by silver, the enzyme that acts as a respiration loses its efficacy, and the microorganisms die rapidly. Silver ions are particularly bactericidal, killing most bacteria in water with as little as two hundred millionth of silver ions per liter of water. A scientist in the United States has experimented with 4.5 liters of sewage (more than 7,000 E. coli per ml) after three hours of silver electrode treatment, and all E. coli died. Typhoid bacteria can only live for 18 hours on silver tablets, and diphtheria bacteria can only live for 3 days on silver tablets.

It is precisely because of the strong bactericidal ability of silver, and no harm to humans and animals. At present, more than half of the world's airlines have used silver water filters. The swimming pools in many countries are also cleaned with silver. The purified water does not stimulate the swimmer's eyes and skin like the water purified by chemicals. Silver ion antibacterial agents are also applied to textile fabrics. The widely recognized silver ion antibacterial agents include the Sanitized series of Swiss Mountain Ningtai and the silver ion antibacterial agent Silpure FBR-5 from TRA Canada.
