    ii) a first pleated filter element disposed along the central axis and within the interior cavity of the housing for conditioning fluid traversing the first flow path from a first inlet port to a first outlet port;

    iii) a second pleated filter element disposed along the central axis and within the interior cavity of the housing for conditioning fluid traversing the second flow path from a second inlet port to a second outlet port; and

    iv) a third non-pleated filter element disposed along the central axis and within the interior cavity of the housing for conditioning fluid traversing the third flow path from a third inlet port to a third outlet port; and
