You just haven't driven enough. Those filters not filter out contaminants nearly as well as a paper filter. In addition, the surface area is not as large as the paper filter that came on the 4BT from the factory, meaning that they clog faster.
Only reason I'm running one is because I haven't saved up my pennies for a donaldson yet.
J, Do you have a part# for the Donaldson. Interested to see the specs.
