    Notes:
    1. Bubble Point is the minimum pressure required to force air through a membrane which has been prewet with water.
    2. Flow rate indicates initial flow rate at 10 psi using a KGS 47 filter holder:
          Water: using prefiltered (0.1μm) water
          Air: using prefiltered nitrogen
    3. Porosity refers to the percent open area.
