Scientists Develop Air Filter That Traps and Kills Coronavirus

The key to its success is that the virus can’t survive temperatures above 70 degrees Celcius, so heating it well beyond that kills the virus almost instantly. Nickel foam is an ideal material because it’s porous, which allows for air to flow through it, but it’s also electrically conductive, which means it can be heated. Zhifent Ren, a co-author of the study, says the filter could be used in airports, office buildings, schools, and cruise ships to control the spread of the virus.
