From the article :
If the surface does not destroy the virus or microorganisms that have fallen on it, the contaminated particles can penetrate the mask by various mechanisms such as capillaries [15].
Furthermore, a mask often becomes a virus collector during repeated breathing activities, particularly when its outer surface is exposed to contaminated droplets [8,16]. Given that viruses and bacteria will stay on the surface and in the masks during wear for a considerably long period of time, it is obviously dangerous and undesirable if they can live safely and remain active in the warm and humid microenvironment in the masks. Due to the conditions of the mask and the high humidity and temperature created during the respiration cycle, it will lead to the formation of steam in the mask, and this process will accelerate the mechanism of penetration and faster spread of microorganisms to the inner parts of the mask.
