But as tens of millions of people return to public transit, their workplaces and schools, are these interventions enough? ADVERTISEMENTResearchers are increasingly looking at the pandemic through the lens of engineering, devising ways to make indoor environments safer. Hepa (high-efficiency particulate air) filters—technology that first came to market in the 1950s—are used widely in hospitals, biocontainment labs and airplanes. By heating the foam to 200 degrees Celsius, the researchers were able to eliminate 99.8 percent of airborne SARS-CoV-2 virus from a room on first pass. Researchers at the University of Arizona recently proposed widespread use of coatings as a new line of defense against SARS-CoV-2.
