Independent clinical testing confirms PURO Lighting disinfection of viruses, bacteria, and fungal pathogens. Our UV disinfection lights, powered by Violet Defense® technology, have been proven to rapidly kill up to 99.9% of SARS-CoV-2, Norovirus, C. diff, E. coli, Salmonella, MRSA, and C. auris. Our UV lights should have efficacy against large, non-enveloped viruses and enveloped viruses, as our units have been proven effective against small, non-enveloped viruses, the hardest-to-kill class of viruses.
