David,

Would you have any recommendations for an air filtration system? My
workshop will be rather small (about 13' x 18'), but large enough to
warrant addressing the dust problem.

I too will have a DC system of some sort, but I was in fact concerned
about the dust and particles that will ultimately fill the environment.
I'll wear a dust mask when sawing, but I'd rather not have to keep it on
after I'm done sawing. The fine particles float around for quite some
time.

wondering if I wouldn't be as well off buying a strong shop vac and
connecting as needed.

All advice appreciated.

DC collects SOME of the dust and wood chips, but there will still be
some airborne dust. For that, you can install an air filtration unit.
They are quiet and some have remote controls. mount in a high,
central location. I don't have a severe enough problem with dust in
my shop so I haven't purchased the filter, but I've looked at them and
read about their usage. I think if you are concerned about the dust
laying around, you should realize that you are also BREATHING it in,
so for your health, you might want to seriously consider getting one.
Delta and Jet both make them. There is a small triangular shaped one
with a light under it, available at Lowes. I doubt it is a high
volume unit, however--it's pretty small.

Jack, no, I'm sorry, I'm not up on the merits of the various units
currently available. I know what you mean about wanting to rip off the
mask when it seems the worst of the dust has settled. Problem with
removing a mask just moments after shutting off the saw is that you'll
still be breathing in the fine dust, which is much worse than the large
visible particles. The filtration units should turn over "x" amount of
air per hour to be considered effective. It takes a finite amount of
time to clean the air to a healthful level, so I wouldn't count on a
filter to obviate then need to wear a mask. Capturing the offending
dust at its source should be a high priority, as once it's airborne, it
takes time to remove it. Meanwhile, maskless, you are breathing in tiny
particles which can lodge in the lungs. As uncomfortable as it may be,
I say keep your mask on. I use the disposable N95 type masks unless
spraying. then I wear an organic vapors respirator.
