Thanks Thomas,<br>

From the sound of it, it seems like you're suggesting that neither
fresh air from outside nor exhausting shop air is necessary---that a
good air cleaner will do the job. That's fine with me, since it
would save energy and obviate the need for makeup air. For that, I
would be more than willing to tolerate a bit more noise--but it just
seems almost too good to be true. I suppose I could go with the
air-cleaner and add other ventilation later if I need to. In any
case, the concern with the fine dust is more than valid, and I
don't think an exhaust fan would completely deal with that. <br>
<br>
Thanks also to Clarke for the shop vac exhaust suggestion. It's an
option I hadn't considered. <br>

the problem with relying on a shop vac or dust collection
system hooked up to your tools is it only gets the
majority of the dust. those fines don't get past the
filter, they are just propelled into your work space willy
nilly, so having an air cleaner that can do lots of air
changes rapidly takes up the dust collection slack. with
a small shop like you propose, you will rarely, if ever,
notice any dust in the air while running a circulating air
filter. <br>
<br>
If you have a shop vac hooked up to your tool then I'd bet
you wouldn't need a respirator until you apply finishes.<br>
<br>
It would be nice to have a voc filter for the unit.<br>

Exhausting the shop vac to the outside is a way of

pulling air in - preferably through<br>

my main dust collection system, and I'll be using a

But intuitively, one would think that bringing in some
fresh air would be a good idea too.<br>

Especially after finishing the reno, building some
storage, etc., the shop will be for occasional use.
And I haven't seen much advice for such small shops,
except for Bob Villa recommending an exhaust fan,
without elaborating about size, makeup air, etc.<br>
