Filter-housing interface designs for heating, ventilation, and air conditioning systems

A support element for a filter element for a heating, ventilation, and/or air conditioning (HVAC) system, the support element comprising:

• a first interface member extending along a longitudinal direction;
• a second interface member spaced apart from the first interface member and extending parallel to the first interface member;
• a connecting member configured to couple the first interface member and the second interface member to a filter media pack, the connecting member extending from the first interface member to the second interface member;
• and
• a magnetic material disposed on a first longitudinal end of at least one of the connecting member, the first interface member, or the second interface member.

A filter element for a heating, ventilation, and/or air conditioning (HVAC) system, the filter element comprising:

• a filter media pack;
• a first support element coupled to the filter media pack;
• and
• a second support element coupled to an opposing end of the filter media pack as the first support element, wherein the filter media pack is reconfigurable between a collapsed position in which the first support element and the second support element are separated by a first distance along an expansion direction of the filter media pack, and an expanded position in which the first support element and the second support element are separated by a second distance along the expansion direction that is greater than the first distance, wherein the first support element includes a snap-fit interface that is configured to couple the first support element to a housing rail.
