Yes! In a clinical lab trial, the UVi Beam’s high-power ultraviolet LED technology was proven to begin neutralizing E. coli strains within in one second, and was 99.99% effective in killing the bacteria. Additional clinical testing has shown the same results on a variety of microbes and genetic pathogens, including coronaviruses and the seasonal flu. The longer you use the UVi Beamon a surface, the higher the sterilization rate and the lower the spread.
