Colorado company uses UV lighting to kill bacteria and viruses

A Colorado company is offering a new kind of way to disinfect surfaces and spaces amid growing concerns over COVID-19. Puro says it offers a UV lighting technology designed to kill 99.9 percent of bacteria and viruses. 'Our lights will run for about a 30-minute period and during that time produce a significant amount of UV to kill any type of bacteria and virus or most fungal strains within a space.'
