![]() But that’s unlikely to happen because people prefer the look of shiny stainless steel because it appears cleaner than copper, which starts to look dirty and dingy over time.Īnd it’s not a given that what makes a copper surface so good at killing germs would have the same effect when someone wears a mask made of it over their nose and mouth. If all of the high-touch surfaces we encounter in society on a daily basis-think doorknobs, countertops, railings, handles, and so on-were made of copper, there’s an argument to be made for a potential reduction in disease transmission, Hart notes. “The cells of those membranes are in a hostile environment and eventually the reactivity will break cell walls down and destroy the RNA and DNA in the cells,” he says. That reactive surface is a really hostile place for something like bacteria. So if you put a cell on there, it has to deal with an environment that is actively oxidizing. Think of a shiny new penny: the reason it gets darker over time, with very old pennies being black, is because “the copper metal is doing everything it can to react with oxygen in the air and form this new compound called copper oxide,” Hart tells Yahoo Canada. “Further research is needed.”Ĭraig Hart, director of the Mineral Deposit Research Unit in the department of earth, ocean and atmospheric sciences at UBC, explains that copper is highly oxidative, meaning it oxidizes very quickly. “Currently, no data are available on the use of the Kuhn All Copper Mask and the Kuhn All Copper Mesh Insert with coronavirus,” Kuhn’s website says. While copper surfaces have been proven to be lethal to some microbes, the science is lacking when it comes to the material’s potential to reduce the transmission of germs when used in face masks.ĪLSO SEE: Here’s where you can buy non-medical masks for kids online The venture carries several styles, with a two-pack of Endura Masks going for $30. Based in Toronto, it’s making textile face masks that contain copper and silver yarn, “known to maximize protection against bacterial and viral threats” its website says. ![]() Kuhn’s masks are flying off the shelf the company’s website states that because of increased demand, orders are taking two to three weeks on a first-come, first-served basis.Īnd the company isn’t the only one producing copper masks around the world. “Consequently, copper alloy surfaces could be employed in communal areas and at any mass gatherings to help reduce transmission of respiratory viruses from contaminated surfaces and protect the public health.” “Exposure to copper destroyed the viral genomes and irreversibly affected virus morphology, including disintegration of envelope and dispersal of surface spikes,” the authors wrote in the study, which was supported by the Copper Development Association and the International Copper Association. Also known as alpha coronavirus, it’s not the same kind as the novel coronavirus that causes COVID-19.)ĪLSO SEE: Should you wear jewelry during COVID-19?

Multiple studies going back years back up the claim that copper kills various germs.Ī 2011 study published in Environmental Microbiology, for example, found that Escherichia coli (E. “In published reports, copper is known to inactivate most coronaviruses, flu, and respiratory viruses and kill bacteria on contact,” the site says.ĪLSO SEE: Where to buy non-medical masks in Canada The latter can be used with regular surgical or cloth masks (and comes in a set of two for $25 USD).Īccording to the company’s website, both products allow a tiny amount of copper to be deposited in the nostrils during use. the Kuhn All Copper Mask, which retails for $25 USD) as well as the Kuhn All Copper Mesh Insert. The company makes the “Well Mask” (a.k.a. She first started making them years ago in an attempt to avoid getting sick due to so much air travel, turning to copper because of its antimicrobial and antiviral properties. The theory is that the material that pennies are made of could reduce the spread of the novel coronavirus.įlorida-based microbiologist Phyllis Kuhn, the founder of Kuhn Copper Solutions, developed a face mask and an insert made of copper. Now, we’re hearing about masks made of copper. We’ve gone from basic surgical and N95 masks to home-made styles made of scarves and socks to stylish version bedecked with sequins. Masks have come a long way since COVID-19 hit the world in earnest earlier this year. The Kuhn All Copper Mask (Photo via Kuhn Copper Solutions)
