I was looking up the best budget dust filter to use, and I came across 2 threads on hardform and here.

The common recommendations I saw was Silverstone and Demciflex. Demciflex said their filters were medical grade synthetic 100 micron filters.

A fellow here went to ebay and bought some nylon filter of the same size, but said the holes were way too small. He didn't mention how it performed
So if 100 microns was too small, what's the right size?
Silverstone uses nylon filters but their website doesn't say the mesh size. So I contacted them and they got back to me with a mesh size of 258 microns. It's 2.5 times bigger than Demciflex's mesh. They also included some test results about filtration efficiency and drop pressure, which I couldn't make sense of it. Showing me data that says it's only 5% effective at blocking something is very strange, are they trying to talk me out of buying their filters?
And what is the effect of air pressure drop on the air flow? 0.4 mmH2O is 4 Pascals
Those who have used Silverstone filters, are these good at blocking dust without impeding airflow too much?
Fine dust seems to be much smaller than 250 microns though, they are said to be between 10 and 100 microns
