Scientists have designed an air filter that can both catch and kill the coronavirus by trapping and neutralizing it instantly. The new invention could be used to reduce the spread of the virus in enclosed spaces.

The study, which appeared in Materials Today Physics on Tuesday, states that 99.8 percent of Covid-19 is killed within a single pass through the filter.

The device was also found to kill 99.9 percent of the spores of the deadly bacterium Bacillus anthracis, which causes the anthrax disease.

What makes the device remarkable is that it is made by commercially available nickel foam heated to 200 degrees Centigrade.

“This filter could be useful in airports and in airplanes, in office buildings, schools and cruise ships to stop the spread of Covid-19, its ability to help control the spread of the virus could be very useful for society,” said Zhifeng Ren, director of the Texas Center for Superconductivity at the University of Houston, who collaborated with Monzer Hourani, CEO of Medistar (a Texan real estate firm) to create the device.
