Researchers from the University of Houston developed, in collaboration with others, an air filter that can kill SARS-CoV-2, commonly known as Coronavirus, or Covid-19.
This filter is made out of nickel foam, which is porous, electrically conductive, and flexible, heated at 200 degrees Centigrade. Tests have shown that 99.8% of the SARS-CoV-2 virus was killed in a single run, and 99.9% of anthrax spores were killed too.
The development of this air filter was important, because SARS-CoV-2 can live around three hours in the air, and survive temperature up to 70 degrees Centigrade, a temperature very unlikely to happen in a building. Therefore, the filter was made to heat the air at very high temperatures, resulting in destroying the virus almost instantly.
This air filter could be installed in airports, airplanes, buildings, and many other enclosed spaces to help stop the spread of the Coronavirus, and help us get back to a more normal life.
