Hi Jeff, If you are talking about an air filter, it depends on the amount of dust that can be ingested. Anything over 2 micron is a wear particle in oil, the exception might be carbon dust if from a charcoal gasifier. If you are using it for a final gas filter, anything over "about" 15 micron is most likely to impact on the bends of the inlet manifold, so in the end you need a filter that can reduce the nuisance factor of blocked manifolds. Possibly you don't see any collected solids which is a great thing, but traditionally charcoal filters were just cotton fabric bags.
Don't forget the oil though, as that will blacken up very quickly if sub-micron carbon dust is present. Hope this might be of some help. Doug Williams, Fluidyne.
