*BFE: Bacteria Filtration Efficiency, Percentage of particles filtered out at a pore size of 0.1-1.0 microns(u).
*PFE: Patriculate Filtration Efficiency , Percentage of particles filtered out at a pore size of 0.1-1.0 microns(u).
*Delta P: Differential Pressure, Pressure drop across mask or resistance to air flow in mmH2O/cm2. Greater resistance = better protection but less breathability
