The company's UV air purification systems, which can be used as a prevention tool to limit the spread of influenza, consist of a high-intensity UV quartz lamp that produces UVC (which destroys viruses, bacteria, mold, and other microorganisms) and UVV light. The systems have been tested and found to be up to 99.9% effective in destroying airborne tuberculosis, which is almost three times more resilient than influenza. Should the Avian Flu virus be airborne, a properly sized UV air purifier (taking into account air velocity, size of ductwork, and/or application) can destroy the Avian Flu virus should it pass through the UV system, according to the manufacturer.
