To have a spray booth you simply must have air going in one side (the side
you are on), and out the other(the side with exhaust fan). then you must
catch the particles that you spray that dont stick to your pot with
an appropriate filter, this keeps you from breathing the dust . Granger
and other industrial and paint suppliers sell the filters. If you are
spraying flamible paints, the fans and all electricals must be explosion
proof, and you are better off purchacing a package booth.

Although this is mostly accurate, I must speak up about one thing you said
above. You imply that a filtered spraybooth can be vented right into the
room, and that should never be done with any spraybooth used for
glaze-spraying or for handling dry materials, regardless of the filter
provided. In my experience, in a situation where all particulates must be
removed (right down to the extremely dangerous sub-micron particles), it
requires a very powerful suction fan, and a water curtain and/or a large
array of very expensive HEPA filters. Needless to say, this is not feasable
for the studio potter. The practical solution is to use an ordinary
low-restriction HVAC filter at the back of the spraybooth (behind a baffle
wall), and vent the spraybooth outside. The filter will remove most of the
overspry, and any dust getting through will just dissipate harmlessly
outside.
