OnePlus, a manufacturer in Hefei City, Anhui Province, recently put into production masks that can inactivate viruses and bacteria. This mask looks similar to an ordinary N95 mask, the only difference is that the non-woven material is orange-red.
According to an interview with a reporter from China News Network, the non-woven fabric of this mask contains active metal copper ions, which experiments have proven to be effective in killing bacteria and viruses. Because the copper ions in the fiber are effective for a long time, the mask can be used repeatedly about 60 times. This technology has been verified by the State Key Laboratory of Emerging Infectious Diseases of the University of Hong Kong. According to the report issued, this material can reach or exceed the titer of 104 PFU/ml for the new coronavirus after 10 minutes of exposure. Close to 100% inactivation efficiency. For the new coronavirus with a titer of 105 PFU/ml, it can achieve close to 100% inactivation of the virus after 60 minutes of action.
According to the person in charge of the company, the company began research and development in April this year to apply copper oxide non-woven fabrics to masks. In more than half a year, this mask was quickly put into production and obtained various inspection certificates and registration certificates required for listing at home and abroad. At present, the company has received domestic and foreign orders for 250 million pieces, and the order value is expected to be more than 1.5 billion yuan.
IT House learned that heavy metal ions such as copper, silver, and lead can destroy the cell membranes of bacteria and fungi, causing them to die. At the same time, various viruses will undergo oxygen reduction reactions and die quickly when encountering copper ions. Therefore, no bacteria can survive on the surface of door handles and other daily necessities made of brass.
