Abstract: A filter element includes a first, outer tubular construction of filter media defining a first open filter interior; a second, inner tuber construction of filter media defining a second open filter interior; the second construction of filter media being located within the first open filter interior and being radially spaced from the first construction of filter media; and the second open filter interior defines an unfiltered fluid channel. A plastic inner liner is within the first open filter interior to support the first construction of filter media. A plastic outer liner is within the first open filter interior to support the second construction of filter media. A filtered fluid channel is defined between the inner liner and the outer liner. A brace arrangement is between the first and second tubular constructions. The brace arrangement can include a spring, a plurality of gussets, or a solid spacer.
