    Default Researchers Create Air Filter That Can Kill The Coronavirus

    University of Houston
    July 7 2020

    Researchers from the University of Houston, in collaboration with others, have designed a "catch and kill" air filter that can trap the virus responsible for COVID-19, killing it instantly.
    Zhifeng Ren, director of the Texas Center for Superconductivity at UH, collaborated with Monzer Hourani, CEO of Medistar, a Houston-based medical real estate development firm, and other researchers to design the filter, which is described in a paper published in Materials Today Physics.

    I don't know enough science to speculate on the downsides, but there must be some. Maybe price!

    In the article, "The researchers reported that virus tests at the Galveston National Laboratory found 99.8% of the novel SARS-CoV-2, the virus that causes COVID-19, was killed in a single pass through a filter made from commercially available nickel foam heated to 200 degrees Centigrade, or about 392 degrees Fahrenheit. It also killed 99.9% of the anthrax spores in testing at the national lab, which is run by the University of Texas Medical Branch."

    That's seems like a lot of heat to sterilize a lot of air. I'd be interested to know how that is accomplished without heating the entire abode???

    From the article: "By making the filter electrically heated, rather than heating it from an external source, the researchers said they minimized the amount of heat that escaped from the filter, allowing air conditioning to function with minimal strain."

    Hence the electrically conductive "...nickel foam..." Thanks for that explanation, Julieanne.
