IIRC, the take off for oil pressure is downstream from the filter. Therefore,
an increase in oil pressure would be do to increased flow through the filter.
In another life, I worked for a company that sold filters. There were
basically two types-a surface filter with pores of a specific size that would
stop particles bigger than the holes. The other type was a depth filter,
which trapped particles as they hit the fibers. Picture the first type a
sieve and the second type as a thick forest. If you were to fire a rifle into
a forest, the bullet is apt to hit a tree rather than pass through the forest.
Depth filters give better flow and have a larger capacity to hold particles.
Modern screw on filters are surface types, the felt is a depth filter.
