Filter with variable cross-section axial seal

A filtration system, comprising:

• a housing defining a central compartment therein, the housing including an outlet and a housing sealing surface, the housing sealing surface being non-planar;
• a cover removably coupled to the housing, the cover including an inlet and a cover sealing surface;
• and
• a filter element positioned within the central compartment of the housing, the filter element including filter media and a seal member coupled to the filter media and circumscribing at least a portion of the filter media, the seal member including a first sealing surface and a second sealing surface, the first sealing surface has an arc-shaped profile extending from a first end of the seal member to a second end of the seal member, the second sealing surface has an opposite arc-shaped profile extending from the first end of the seal member to the second end of the seal member, each arc-shaped profile defines a convex arc shape comprising a continuous curve between the first end and the second end, the seal member having a variable cross-section such that, at a perimetral distance from the filter media, an axial distance between the first sealing surface and the second sealing surface varies along at least a portion of the seal member, the variable cross-section being complementary to the housing sealing surface and the cover sealing surface such that the seal member forms an axial seal between the housing and the cover when the filter element is installed in the air filtration system.
