Generally reputable manufacturers will do selective analysis of a product on their production line from time to time as well as extensive tests of the prototype prior to putting it into production. So its likely it will perform to its intended applications.

I am sure there are standards that filters have to meet too....at least I hope there are. You can always analyze them yourself too to make sure they are working properly. But that could be expensive. $$$

On the oil filter in my car there is a lower full flow portion made of pleated paper media; the companies can and have told the micron ratings on that portion of the filter. They are speechless on the rating of the upper bypass portion of the filter; I think it is because the do not know the performance of this part of the filter.
While I could have an oil analysis done on the crankcase oil I have no way of testing the performance of each of the separate parts of the filter by themselves without building some sort of test bench; which I do not plan to do.

I believe in the massive oil filter thread it was found that the typical upper bypass section of the stock filter ranges from 15 micron (Baldwin dual pleated paper style) to 25-30 micron for the packed cotton material. Once I run out of Fram filters I am going to switch to the Baldwin filters and call it good enough.
