A fluted filter element may include one or more bridging elements to provide resistance to telescoping of the layers of the fluted filter element. The bridging elements are attached to one or both of the filter faces via adhesives, and/or mechanical means, and may also take the form of one or more beads of adhesive applied across one or both ends of the filter element. The adhesive beads may include a flexible element, such as a string, or strip of material embedded in the adhesive bead.
