The problem is that a dust collector will not pick up all the small 
particles that still get into the air.  The air cleaners were not meant 
to replace a dust collector.  For a nice clean, healthy shop both seem 
to be the way to go.

We use a HEPA filter (Honywell) in addition to the dust collector.

We've also adapted a $180 HEPA filter to use as a welding fume /smoke collector.
Works pretty good considering the alternatives cost $2000.

Several other cabinetmakers I know hang $10 box fans from the ceiling and
strap a 2" 25x25 furnace filter over the intake.
They leave them on 24 hrs a day.

Spray a little spray adhesive (like spray mount)  over the filter to
capture finer particles.

I just started reading this group- excuse me if this has been covered before.
