Notes: Caliper Test :The thickness measured at a specific pressure. Frazier Test : The column of air, in CFM , that can flow through 1 square foot of media
0.5 W.G. pressure drop . Mean Flow Pore : The average particle size. Flat Sheet Multipass Efficiency: Beta 200 or 1000: Size of contaminant that can be
captured with a efficiency of 99.5% for Beta 200, and 99.95% for Beta 1000. DOP Penetration test: 0.3 micron particle @ 32 l/min/cm2
