KF-Sunshine AOP-KF protective masks -- the latest product by technology company KF-Sunshine -- can achieve a virus and bacteria inactivation rate of 99 percent, according to the product launch.

The masks use advanced air purification material AOP-KF® solid base that is independently developed by KFIAQ, which owns KF-Sunshine and has obtained invention patents in China and the United States, said Li Guopei, founder of KFIAQ.

According to Li, the AOP-KF® solid base is a green and safe disinfectant and purification material featuring significant antibacterial and antivirus effects. It is safe and reliable and has been tested by a large number of third parties.

The Modderfontein Laboratory in South Africa previously found that the product was sterile even after it was worn eight hours a day for seven consecutive days.

KF-Sunshine is located in the Zhongan Chuanggu technology park in the Hefei National High-tech Industry Development Zone. It has solved AOP-KF production difficulty and realized mass production there.
