1. A filter assembly, comprising:
a filter media body including a cylindrical filter media outer side surface defining a first diameter and extending between a first filter media end surface and a second filter media end surface; and
a compression ring disposed adjacent to the second filter media end surface and including a first end surface defining a width of the compression ring and an outer ring surface extending from the first end surface and defining a length of the compression ring, the outer ring surface having a second diameter that is greater than the first diameter, the compression ring including one or more fluid channels each defining (i) a radial channel portion extending continuously through the entire width of the first end surface from a first end adjacent to and in direct fluid communication with the second filter media end surface and (ii) an axial channel portion extending from the first channel portion through the entire length of the outer ring surface to a second end adjacent to and in direct fluid communication with the filter media outer side surface.
