I used to occasionally work in a clean room
where microchips were made. Air was filtered, everyone wore suits covering everything and you had to tear your feet off the sticky mat in the airlock that sucked every last piece of shit off the suit and very nearly the suit too.
You could open the PCs in there and not see a trace of dust after a couple of years even on the outgoing filters. The mice rollers would still get covered in blue grey lint. I think it must be created by quantum fluctuations and dark matter is really the stuff that doesnt stick to mice rollers.
