Antibacterial mask anti virus mask KN95 anti COVID-19 mask
According to the report, although a standard three-layer surgical mask can prevent the spread of the new coronavirus and other pathogens through droplets, the virus can still survive on its surface if it is not properly disinfected or properly disposed of.
Dr. Gareth Cave, a nanotechnology expert at Nottingham Trent University, designed a unique copper nanoparticle mask. The mask can kill up to 90% of the new coronavirus particles in seven hours. Dr. Kraft’s company, Pharm2Farm, will start producing the mask later this month and sell it on the market in December.
Patented
Copper has inherent antibacterial properties, but its antibacterial time is not long enough to prevent the spread of the new coronavirus in the community. Dr. Kraft used his expertise in nanotechnology to enhance the antiviral properties of copper. He sandwiched a layer of nano copper between two filter layers and two waterproof layers. Once the nano-copper layer comes into contact with the new coronavirus, copper ions will be released.
It is reported that this technology has been patented. Dr. Kraft said: “The masks we have developed have been proven to be able to inactivate the virus after exposure. Traditional surgical masks can only prevent the virus from entering or spraying out. The virus cannot be killed when it appears inside the mask. Ours The new anti-virus mask aims to use the existing barrier technology and nanotechnology to trap the virus in the mask and kill it.”
Dr. Kraft also said that barriers are added to both sides of the mask, so it not only protects the wearer, but also the people around it. The mask can kill the virus when it comes in contact with it, which also means that the used mask can be safely disposed of without becoming a potential source of pollution.
Meet the IIR type mask standard
According to reports, this copper nanoparticle mask is not the first to use a copper layer to prevent the spread of the new crown virus, but it is the first batch of copper nanoparticle masks that meet the IIR type mask standard. Masks that meet this standard can ensure that 99.98% of particulate matter is filtered.
