    Researchers Create Air Filter that Can Kill the Coronavirus

    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.

    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.

    you ever breathe in 200C air todd?
     
  3. Basically they discoverd that extreme heat kills a virus, which I think was self-evident....not sure how they can implement this though...not like you can put a heated filter in office spaces or hospitals.

    You could capture the heat.. I was reading another paper a while back that found 2 millijoules per cubic centimeter of around 222 nanometer UVC light is enough to deactivate the virus and also influenza. It is well absorbed by things like peptide bonds in the virus.

    I expect you would have an ozone odor from the treated air but if the air was prefiltered of dust silicates etc. probably not so bad.

    A hybrid solution might be effective, lower temperature plus UVC.

    All that is needed is a filter:D
