Have you had your oil tested to see whats in it or how bad it is? There can be all sorts of issues causing the oil filter to plug up quickly. Oil sampling will give more insight into whats causing it.

excess soot problems will make an oil filter clog up like that. It is typical of ISX engines.
Excess soot problems can be anything from bad sensors to a sticky EGR valve, turbo out of calibration of failing, incorrect program in engine, to a bad CAC unit.
