1. A filter element configured for positioning between a first housing section and a second housing section of a housing, the filter element comprising:
filter media; and
a filter element border extending from the filter media in an x-y plane, the filter element border comprising a first axial sealing surface, a second axial sealing surface, and circumferential surface extending between the first axial sealing surface and the second axial sealing surface, the second axial sealing surface being opposite the first axial sealing surface, the first axial sealing surface providing a mating interface for engagement with a surface of the first housing section, the second axial sealing surface providing a mating interface for engagement with a surface of the second housing section,
one of the first axial sealing surface of the filter element border and the second axial sealing surface of the filter element border comprising one or more axial projections projecting in a z-direction that is perpendicular to the x-y plane such that the one or more axial projections are part of the one of the first axial sealing surface and the second axial sealing surface, each of the one or more axial projections positioned and configured to engage a respective axial recess of one of the first housing section border and the second housing section border when the filter element is installed within the housing such that fluid flow across the filter element border is blocked,
the circumferential surface of the filter element border comprising a radially extending recess in the x-y plane, the circumferential surface of the filter element border positioned and configured to engage an inner housing surface of one of the first housing section border and the second housing section border, the circumferential surface of the filter element border complementary with the inner housing surface.
