Whether heated air filters can kill COVID-19 and make indoor environments safe

Facts about the novel coronavirus have been hard to pin down. But scientists at the University of Houston took two things they knew to be true and ran with them. Fact one: COVID-19 droplets can linger in the air. Fact two: Those droplets don’t like high heat.

The Texas scientists then created heated air filters that can instantly catch and kill the virus. It’s a potentially crucial development to get people back indoors — in offices, schools, and convention centers.
