A filter element, and filter apparatus, include a filter pack, a seal member, and a seal support frame operatively connecting the seal member to the filter pack. The seal support frame includes an annular extension, which is preferably canted at an oblique angle to a longitudinal axis, for supporting the seal member. The seal support frame also preferably includes a first end thereof including the annular extension, and a second end thereof spaced from the first end thereof along the longitudinal axis, with the first and second ends of the seal support frame joined by a hub of the outer peripheral sidewall of the seal support frame to define a cavity within the seal support frame for receiving the filter pack. The first and second ends of the seal support frame, and the filter pack are preferably joined and sealed to one another by a single bead of adhesive.
