Kn95 mask is not recommended to be used repeatedly. Generally, it is a disposable mask. It is recommended to wear it continuously for more than 4 hours and replace it in time. However, as we usually wear it discontinuously or in an open environment, the mask can be used repeatedly in a short time.
The used mask can be placed in a ventilated place and exposed to sunlight for disinfection. If possible, you can put the mask under the ultraviolet lamp for half an hour. You can also put the used mask in the oven at a temperature of 56 degrees Celsius for more than half an hour, which can effectively kill bacteria and play a role in disinfection.
However, if the mask is wet, damaged, or contaminated by pollutants and secretions when we wear it, we must replace it in time.
