Why there is no penetration of microbes below 10 micron defect size in the aerosol challenge test while the size of bacteria is smaller than 10 micron?

Answer

Electric continuity data and previous scientific literature imply that surface tension prevents the formation of a liquid channel for a small defect which is likely the reason for non-penetration of aerosol-based microbes through a defect smaller than 10 micron inside sterile space.
