Over dinner, Laurie Hommema, a doctor, worried out loud about the dwindling supply of N95 masks. Her husband Kevin, an engineer, asked why they can't just be reuse. And that was when a solution was born. Kevin remembered a study his colleagues had conducted five years back, showing how masks could be decontaminated and reused in an emergency. They immediately emailed their teams to explore this and, in just 15 days, the U.S. Food and Drug Administration granted Kevin's company emergency authorization to deploy decontamination systems -- that can clean 80,000 masks a day -- around the country.
