Researchers have designed a "catch and kill" air filter that can trap the virus responsible for COVID-19 and kill it instantly. The researchers - from the University of Houston and in collaboration with others - reported that virus tests at the Galveston National Laboratory found 99.8 percent 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 - about 392 degrees Fahrenheit.
