The filter media may include a first filtration zone extending partially around the hollow passage and between the first fin and the second fin, with the first filtration zone being associated with a first portion of the filter media. The filter media may also include a second filtration zone extending partially around the hollow passage and between the first fin and the second fin, with the second filtration zone being associated with a second portion of the filter media.
