    Consider using a cardboard box with a modest sized HEPA filter on top, a couple more holes in the sides with HEPA filters and a 60W lightbulb inside for a little heat which helps dehumidify the air.

    A low volume fan on the side at the bottom to evacuate air.

    Re: DIY Film Drying Box

    I did something very similar recently for drying silver gelatin plates after pouring, or after development. Allows them to dry in a relatively dust-free environment, and dries them somewhat more quickly. Just threw it together out of some scrap wood, a small fan (of the same sort as on a computer), and furnace filters. Seems to work well enough...

    On a suggestion from Mark Osterman, I plan to line it with cardboard (just using double-stick tape, so it can be removed/replaced). May consider heating the air slightly by putting a small light bulb near the inlet filter, but it's not necessary.

    Robert, how dust would you say you have eliminated with your new box

    I cannot quantify it precisely, but the amount of spotting I have to do (generally digitally on the scanned images) has decreased significantly. That is, before I had to do a lot, so far with the new box, I don't have to do much at all.

    Newly poured plates used to take most of the day to dry completely; now it's down to about 5 hours, and I suspect I can get it a bit lower still.

    I was thinking a hepa filter might be overkill. The paper style furnace filter (per Robert Brazile) might work fine. I've used these in smaller openings but just cutting them up.
