Fluid filters and methods of use
First Claim
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.

Abstract
Multiple staged filters are provided herein. A filter may include a plurality of panels that each include a filtering front surface and a flat back surface, the filtering front surface having a first row of vertically extending protrusions spaced apart from one another to form vertical channels, a second row of vertically extending protrusions spaced apart from one another to form vertical channels, and one or more rows of filtering protrusions, where the one or more rows are vertically spaced apart from one another and extending between the first and second rows of vertically extending protrusions. Further, each row of filtering protrusions may include filtering protrusions that are spaced from one another to form filter channels having a size that is configured to receive and retain objects of a given size.
