Doug,
I don't know how the filters are actually tested, either, but I
would suspect that one could feed air through the filter at a fixed
pressure and measure total cubic feet per minute flow. You could
probably even do thi in a home shop if you can isolate the inlet side
of the filter from the outlet side. Use a low-pressure air
compressor on the inlet, and an empty garbage bag on the outlet. The
trick would be to keep the back-pressure on the inlet constant.
