1. A substrate panel for filtering a fluid, the substrate panel comprising:

  • a filtering front surface and a flat back surface, the filtering front surface comprising;

    a first row of vertically extending protrusions spaced apart from one another to form vertical channels, the first row proximate an inlet of the substrate panel;

    a second row of vertically extending protrusions spaced apart from one another to form vertical channels, the second row proximate an exit of the substrate panel; and

    one or more additional rows of filtering protrusions, the one or more additional rows being vertically spaced apart from one another and extending between the first row and the second row of vertically extending protrusions;

    wherein a length of each of the vertically extending protrusions of the first row extending in a direction from the inlet to the exit is greater than a width of each of the vertically extending protrusions of the first row, and wherein a length of each of the vertically extending protrusions of the second row extending in the direction from the inlet to the exit is greater than a width of the each of the vertically extending protrusions of the second row; and

    wherein the substrate panel is rolled onto itself to form a spiral that is layered such that at least a portion of the filtering front surface mates with the flat back surface.
