LENEXA, KS (KMOX) – The US Environmental Protection Agency says some copper surfaces kill coronavirus.
In a release, the agency says, “certain copper alloys provide long-term effectiveness against viruses, including SARS-CoV-2, the virus that causes COVID-19. As a result of EPA’s approval, products containing these copper alloys can now be sold and distributed with claims that they kill certain viruses that come into contact with them.”
The EPA points out, not all copper products can carry those claims. They have to be a certain antimicrobial alloy containing nearly 96-percent copper.
“New efficacy testing supported by the Copper Development Association and conducted according to EPA’s protocols demonstrated certain high-percentage copper alloy products can continuously kill viruses that come into contact with them. Based on testing against harder-to-kill viruses, EPA expects these products to eliminate 99.9 percent of SARS-CoV-2, the virus that causes COVID-19, within two hours.”
Those alloys could be manufactured into a wide range of surfaces, including doorknobs and handrails. The agency says the material could be a supplement, not a replacement for standard infection control practices.
