1. A monolithic open cell structure apparatus, comprising:
an open cell structure housing comprising a first side, a second side opposite the first side, a first opening located at the first side, and a second opening located opposite the first opening at a second side;
a filtration portion extending from the first side to the second side within the open cell structure housing, the filtration portion having an open cell structural geometry that includes a plurality of cells; and
a retaining partition that at least partially encloses the filtration portion within the open cell structure housing, wherein the retaining partition includes a plurality of individual sections, each section having a plurality of pillars configured to fit within a cell of the plurality of cells,
wherein the monolithic open cell structure apparatus is a single piece comprising a unitary structure.
