Antimicrobial Copper possesses highly antimicrobial effect when used in the touch-surface.

99.9% of the pathogens are killed within 2 hours on it, and its effect continues almost forever　because it is the natural and intrinsic copper’s property. Copper is the only solid material approved to claim the antimicrobial effect by EPA. Also, because it is the natural material, it is absolutely safe for anybody, especially friendly to the small children and elders who may not have enough resistance to disinfectants and tend to develop allergy to chemical materials.

Therefore, using antimicrobial copper as touch-surfaces where everybody touches and transmits the infections, such as door-knobs along with normal infection control protocols such as hand-washings and sterilization control, can reduce the number of pathogens in the hospital.
