the really hazardous stuff is sub 1 micron. Large particles your lungs
can clear, but the smallest ones go in there and don't come out.

A 30 or 5 micron bag will make your shop look dustless, and than can be
nice, but isn't going to do much of anything for your health.

Get a bag, or a canister filter plus cyclone, that
can get the finest dust.
