I don't do my own printing but load sheet film. I had bad dust problems but have nto had one since I started using a HEPA filter in the small room that I load film in. I first wipe the dust off of the counter and floor with a damp cloth. Next I turn the filter on for about 15 minutes ing the 6x8 room. Then I will enter the room & close the door & let the filter run for another 5 minutes while blowing each film holder with a blow brush and then load the holders. The holders are inserted into Zip Lock bags and pulled out for use. No dust problems since using these procedures.

One more thing. The HEPA filter I have is a cylindrical Honeywell Enviracare. It has a major drawback in that the filtered air is directed down out of the bottom of the unit. This kicks up any dust off of the floor. If you do get a filter I suggest purchasing one which exhausts the air at the top of the filter.
