520  ‎$a‎Aerosol penetration into a mask can occur by three routes: filter penetration, facial seal leaks, and exhalation valve leakage. The first two mechanisms usually are the most important, although the latter can be significant in certain circumstances, such as when the valve is dirty or malfunctioning. This paper adressess the nature and extent of exhalation valve leakage, that is, back leakage of outside air through the exhalation valve as it closes and seals during inhalation
