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 cuboid protrusions spaced apart from one another to form elongated sidewalls that define vertical channels, the first row of vertically extending cuboid protrusions proximate an inlet of the substrate panel;
a second row of vertically extending cuboid protrusions spaced apart from one another to form elongated sidewalls that define vertical channels, the second row of vertically extending cuboid protrusions proximate an exit of the substrate panel; and
one or more additional rows of vertically extending protrusions, the one or more rows additional rows of vertically extending protrusions being spaced apart from one another and extending in between the first and second rows of vertically extending cuboid protrusions, but not within the vertical channels formed by the elongated sidewalls, the first row of vertically extending cuboid protrusions terminating above the one or more additional rows of vertically extending protrusions and the one or more additional rows of vertically extending protrusions terminating above the second row of vertically extending cuboid protrusions, the one or more additional rows of vertically extending protrusions each having a unique length, which is shorter in length than either a first row length of the first row of vertically extending cuboid protrusions or a second row length of the second row of vertically extending cuboid protrusions, each of the one or more additional rows of vertically extending protrusions comprising a specific polygonal cross sectional area and spacing between protrusions that are selected to filter particles of a particular size, wherein at least one of the one or more additional rows of filtering protrusions comprises filtering protrusions that are tapered to produce filter channels that are each narrower at an inlet end and larger at an outlet end to ensure that objects are trapped in the narrower inlet end.

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.
