The fiber structure on the biochemical mask can completely kill bacteria and viruses. The zinc and copper inside can destroy the bacterial wall and prevent the body from inhaling the bacteria from spreading throughout the body. This biochemical mask has been used in Hong Kong, China and Europe, and it is also expected to be sold in the United States.
Laboratory tests have shown that people release 50 times more bacteria when sneezing than usual, and the newly developed biochemical mask can kill 99.9% of sneezing flu bacteria in less than one minute. In ordinary masks, more than 50,000 kinds of flu bacteria can survive.
