Mask disinfection
Several variants for mask disinfection have been prototyped and Laboratory tests have been commissioned in UK (Surrey Diagnostics) to test performance of cabinets and suitability for Covid19 disinfection.
ECRI / CDC accept UVC 254nm as an acceptable option for decontamination of N95 masks.
JenAct systems offer in excess of 500mJ/cm2.
Cabinets contain disinfection modules emiting UVC light at 254nm and provide in excess of 500mJ/cm2
They use optimized reflectors and transmit and concentrate UVC as efficiently as possible towards inner and outer mask surfaces..
Other items with exposed surfaces can be sanitised also.
