Thanks for all your advice! I installed a vent fan and made a filter box to
hold a 20" x 20" high-efficiency filter. I made the set-up reversible.
With negative pressure and filtered air coming in or positive pressure being
forced through the filter, either way seems to work well. I did take a leaf
blower to the computer in there, clouds of dust!
