Bear in mind every stage added to a system adds a dramatic drop in CFM moved.
I have an aversion to filters primarily due to cost. This can be overcome to a degree by employing washable filters such as restaurant hood grease filters lightly sprayed with peanut oil as long as you can buld filter cleaning into the job cost.
Perhaps the best down & dirty trick to drawing fines from a blower discharge is a barrel with a few inches of water in the bottom. Discharge the blower into the water pool about 6" above the water or higher to eliminate splashing and the water will grab and hold the fines. Then you need a plan to clean the water, but that's fairly easy.
