Sterilization of Face Masks and Respirators (UC 2020-248)

Prof. Lorenzo Mangolini and his colleagues from the University of California, Riverside have developed an efficient and low-cost method to sterilize face masks and respirators with ozone. This novel design uses a flow through configuration where the ozone gas is directly flown through the fibers of the FPRs. The parts needed for construction of this system are widely available and small enough for the device to be easily portable. This approach can readily be adapted for low-cost and simple sterilization of different FPRs to allow for them to be safely reused.
