A new device using a hanging rack and UV-C light can sterilize up to six masks and other items simultaneously and quickly, killing bacteria, yeasts, mold spores, and viruses. This device has shown its efficacy against pathogens including the highly-contagious E-coli, which was eradicated in about one minute.
