Fast and Thorough Disinfection for Face Masks Recycle Using Vacuum Ultraviolet Irradiation

Photoactive decontamination and reuse of face masks

“…Considering the low recycle rate, a vacuum UV disinfection device was made and tested the disinfection effect of its N95 mask. The results showed that the device could inactivate Escherichia coli cells attached to the surface of masks in a few of seconds, the effective circulation rate of the mask can be increased to about 20 cycles [78] . With the introduction of this device, the potential of UV decontamination may be improved for reuse of masks.…”
