Yep, when one uses a filter cap, one has a one pole R C low pass filter where the r is the sum of the equivalent resistance in the rectifiers, transformer etc and the C.
Adding an L makes it a two pole filter and an LCLC makes it a four pole low pass filter.
The lower you make the corner of that filter or the higher the order, the less AC component can come through.
