    Abstract: An expandable air filter. The air filter including a filter media assembly, an outer frame assembly, and at least one support member. The filter media assembly defines opposing, first and second major faces and a perimeter. The outer frame assembly is arranged about the perimeter. The support member is connected to the outer frame assembly and extends across the first major face. Further, the support member defines a line of separation at which the support member can be separated into first and second segment to permit expansion of the air filter. The filter media can form a plurality of pleats, with at least one pleat being free of bonding to the outer frame assembly. The unbonded pleat experiences expansion as the air filter transitions to an expanded state. The air filter can be configured for expansion in one or both of a length and width direction.

    Abstract: The present disclosure generally relates to air filters expandable from a collapsed arrangement to an expanded, end-use arrangement and to methods of making, using, and installing such air filters. Some embodiments relate to an air filter having an expanded state and a collapsed state. The air filter includes a filter media assembly including (1) filter media including a plurality of pleats, (2) first and second opposing sides, and (3) first and second opposing ends. The air filter also includes a shape retention structure capable of being connected to at least a portion of the filter media assembly and capable of retention the filter media assembly in the expanded state. A spacing distance between adjacent pleats in the filter media is greater in the expanded state of the air filter than in the collapsed state of the air filter. In some embodiments, the air filter is an HVAC air filter.
