A filter arrangement includes first and second media packs with a support core in between. The support core includes a first ring at one end and, optionally, second ring at an opposite end. In some arrangements, at least a first member and second member extend from the first ring while being engagement-free to each other. In some arrangements, no more than a first member extends from the first ring, while being engagement-free relative to itself.
