“Sharp Corporation announced on November 17 that it has found its air purifying technology is effective to inhibit bird flu virus.
Sharp plans to develop air cleaners and air conditioners using the “Plasma cluster Ion” technology to help prevent infections of the disease to humans.
Sharp conducted a joint research with Pasteur Institute in Ho Chi Minh City, Vietnam. They found that highly concentrated ions generated using the technology can decrease the infectiousness of H7N9 virus by 99 percent in a container box of 1 cubic meter for about 47 minutes.” (Source: EU-Japan Centre)
