I think you need 2 things:
A cyclone in front of the dust collector to collect the big stuff.
I bought something like the Lee Valley garbage can top cyclone adapter -
works beautifully.

The other thing is the Wynn canister filter to replace the bags on th HF
machine.

I found it a pain to install the plastic bag in place of the bottom canvas
bag, but finally got it in place. With the "cyclone" adapter there is
hardly any need to change the bottom plastic bag.

This should take care of almost all collectable dust. You'll still have
stuff kicked away from the table saw and so, si I finally dispensed with
the paper masks and got a Triton Darth-Vader-type filter. Now my glasses
don't fog, and I can breathe!
