On my dc with the saw, The length of the tubing to the cyclone seems to be enough that I don't get too much past it to the DC bags.
For my router tables, I use my commercial (originally a truck mount) wet/dry vac. Even though it's on a cyclone, it draws too much to separate fines that small. i had to use a large drywall bag before the motor to separate those last fines with that.
