Considering Coronavirus face mask shortages, scientists from Stanford have conducted a study confirming that the N95 masks can be decontaminated in a domestic environment. They suggest that leaving the mask in a regular kitchen oven at 70C/158F for 30 minutes will efficiently sterilize it.
efficiency in N95 masks: 1) hot air (oven), 2) UV light, 3) solution of alcohol, 4) household chlorine-based bleach, 5) steam from hot water. We measured the two most important parameters: the particle filtration efficiency and air pressure drop, before and after disinfection treatments. The pressure drop reflects the air resistance, and a
