That would probably depend on the filter in the vacuum. Typically the
cyclone type separators simply separate the large debris from the fine
dust.
The fine dust is usually captured by a different filter.

Not accurate. I had some very fine saw dust in the bucket in my
review. Almost no sawdust ended up in the shop vac or attached to
the filter.


Fine dust normally does not take up much space, it compacts well. Would'nt
that be what you actually did find in your shop vac?
