Antimicrobial Spray Coatings Test Results
A University of Arizona study tested several ionic silver and copper levels to determine if they were effective against the human coronavirus strain 229E*, a strain commonly used as a surrogate for the SARS virus in laboratory research. The research showed a a 90% reduction of the virus within 1 hour and reduced virus levels to below the detection limit (99.99%) following 24 hours of exposure to the coatings. Further test results include:

AgION technology is currently used in many applications such as sportswear, footwear, pens, mobile phone, appliances like refrigerators, air conditioner system, refrigeration and ventilation, chopping boards for kitchen, medical device, water filter, air filter, ice makers, etc..
A Note on terminology: Viruses are not alive; they must enter a living cell to grow. Therefore, antiviral agents are said to “inactivate” viruses, not “kill” them.
