These folks are not telling you about the anti dust ritual that includes offerings to the gods, and a silly dance around the darkroom sprinkling blessed developer on the offering.
In all seriousness I think it depends where you live. I live in the desert, do everything that these folks have recommended and still get dust at times. I have fewer problems when I load in the bathroom after running the shower for a VERY short amount of time. Open the door until the mirror clears and then reseal to load. Anti static brushes only stop the problem for a very short amount of time around here.
