I was considering using squirrel cage blowers to help keep good air quality
in my studio on top of the usual cleaning. I was thinking of two methods.
Circulate clean air from the outside, into my studio with one blower then
exhaust at the other end with a second blower. Or would it be better to
maintain negative pressure with one strong blower going out? What do the big
boys do?

Hi Charles,
Seems to me...
One Blower causing inside Air to go 'out' by 'pulling', would make for the
least objectionable Air Currents inside ( which currents would be tending to
lift, distribute and carry fine dusts ) ...unless you had a Blower bringing
outside Air 'in' where that Air is distrubuted through a Manifold of some
kind, or directed throgh a diffuser or something, where it would sublimate
any Air Currents as such and make merely for a positive pressure simply.
Aperatures of some sort of course must be provided for air to flow in as
well as out.
I do not know what the big boys do.

It's a good idea but it still means there will be dust in your studio -
better to keep a well ventilated small area for dusty work and work at
keeping the dust from getting air born in the remaining space.
If you create drafts in a studio your pots will dry unevenly so you will
need to construct a draft free area for drying ware.

To add to Ron's idea:
If you have a small area for dusty work,
when you place your exhaust blowers
be sure the blowers are exhausting OUT of that area
to the outdoors (not into your studio). You want _negative_ pressure in
that area,
IOW, it is sucking air in from around it...your "clean" area.
This keeps the dust from going everywhere as well.
Clay and glaze mixing areas, trimming areas, should all be
negative pressure if the process creates airborne dust.
Best,
