From experience derived initially from gloss lacquer spraying of prints and seems to apply to dust on film loading I have found the following. If you are going to clean up, I wont say tidy up, and move stuff around do all that before due time, get all laid out and ready then go and have a cup of tea or some thing. I have found the big change came when I realized that wool or any knitted garment, sort of invented dust. Ones natural movement was enough and quite unbeatable. Dust is always there, like the neighbourhood dog just try to avoid getting it excited.
Vacuum cleaners are dust grinders.
IMHO even the HEPA vacuums create a lot of static charge. Static electricity is a real culprit. If your surface is charged dust will be attracted to it, or your film. I find helps neutralize this. My darkroom has had dirt on the floor but no dust problem.
