1. A filter element for a heating, ventilation, and/or air condition (HVAC) system, the filter element comprising:
a filter media pack defining a plurality of pleats, the plurality of pleats including an end pleat having a length that extends from a first longitudinal end of the filter media pack to a second longitudinal end of the filter media pack; and
a support element including:
a first interface member defining a first lateral end of the support element;
a second interface member defining a second lateral end of the support element and extending parallel to the first interface member, the first interface member and the second interface member engageable with complementary receiving structures of a rail to support the support element on the rail; and
a connecting member coupled to the end pleat of the filter media pack along at least a portion of the length of the end pleat and extending from the first interface member to the second interface member, the connecting member including a concave portion extending from the first interface member and a convex portion extending from the second interface member, wherein the concave portion and the convex portion define at least a portion of an undulating surface on a media-facing side of the connecting member, at least a portion of the media-facing side of the connecting member engaging the filter media pack.
