Germicidal ultraviolet light (UV-C) to combat COVID-19 indoors
Ultraviolet Germicidal Irradiation (UVGI) is very effective at damaging viruses. Because germicidal UV has the ability to damage the DNA of microorganisms they can no longer replicate. And COVID is very susceptible to germicidal UV.
Moreover, there are two air disinfection applications on the market. Because one application uses fixtures that attaches to the wall or ceiling the UV-C light is beamed overhead across a room. As a result, these upper room UV systems reduce the amount of active virus in the air at a much lower energy cost.
