I wonder does we ever get computers (both desktop and laptop) that which not dust inside?

Remember that by using filters you are pretty much killing your airflow (there's a big hit on cfm when using them) so they are not the optimal solution. They also let some dust in sooner or later so they are not the definite solution either. My gaming rig has filters on all intakes and I still have to clean it every month or so.

The dust filter on my computer is pretty transparent, think ladies nylon stocking but a bit more solid material, you can actually make one yourself with nylon stocking, gives almost no air resistance.

Its not an particle filter, it just stop dust particles larger than 0.3 mm, guess so fine dust tend to blow strait trough anyway, as said I have had the case for years in an dusty bachelor apartment with very lite dust inside. Naturally then the filters get clogged with dust they increase resistance and the fans has to run faster, this way you know to clean them. I run my fans at 4-500 rpm, but they can go up to 2500 so I have some margins.
