The number of bacterial aerosol droplets that come into contact with the ,filter, medium is determined by performing ,test, controls in the ,test, system without the ,filter, medium. Difficulty controls are maintained at 3.0-0.3 colony forming units (CFU) with an average ,particle, size (MPS) of 1700 ± 3000 µm.

We compared the ,filter, efficiency against each airborne microbe to analyze the dependency of ,filter, efficiency on the microbial ,particle, size. Our results showed that against the three types of spherical microbe particles, the ,filter, efficiencies against influenza virus particles were the lowest and those against phi-X174 phages were the highest for both types of nonwoven fabrics.
Existing face mask and respirator ,test, methods draw particles through materials under vacuum to measure ,particle, penetration. However, these ,filtration,-based methods may not simulate conditions under which ,protective clothing, operates in the workplace, where airborne particles are primarily driven by wind and other factors instead of being limited to a downstream vacuum.
Filtration, performance of the fabric material cannot be estimated a priori from material composition because it is mostly dependent on fiber characteristics, including diameter, charge, and packing density. Moreover, the finished fabric products do not carry information on fiber properties involved in ,particle filtration,.
