The bag media can easily be tested via a 47mmD disc holder with a peristaltic pump to mimic the flowrate to the actual full-scale bag. The same can be done with the cartridge filter media provided they use pleated ones. If the 1um one is a spun type (e.g., depth) then this cannot be done, In this case, one can test 1" or 4" long cartridges of the same type. I would presume that the 0.2um absolute filter is pleated since they generally are.
