The coronavirus pandemic is altering every aspect of how we live, especially what we want from our homes. Beyond design and space, housing cleanliness is now paramount. New technology that claims not just to clean, but sanitize our living spaces, is in high demand. “Everybody has the spotlight on these germ problems right now. A lot of germ issues were here before the coronavirus and, unfortunately, people are taking a harder look now at how are we really investing to make cleaner and safer places,” said Colleen Costello, CEO of Vital Vio, an eight-year-old company that specializes in antimicrobial LED lighting. Its technology uses visible light to alter the action in cells of bacteria, mold and fungi — but not in those of humans, pets and plants — provoking a toxic reaction within the cells that leads to death.
