    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.

    Abstract: A pleated filter media comprising front pleats and rear pleats, with at least some of the front pleats having junctions at which local areas of adjoining front pleat walls of the front pleat are frontally joined together. The junctions may be at discrete locations that are spaced along a pleat direction of the front pleats. For any two nearest-neighbor front pleats, the junctions of one of the front pleats may be offset, along the pleat direction, from the junctions of the other front pleat.

    Abstract: A filter frame assembly includes a main frame including a first end and a second end, and a spindle unit disposed at the first end. The spindle unit includes a spindle frame, a dispensing spindle non-rotatably coupled to the spindle frame, and a receiving spindle rotatably coupled to the spindle frame. Each of the dispensing spindle and the receiving spindle is configured to receive a filter web thereon in a wound configuration. The main frame is insertable through a filter slot of an HVAC system from the second end, such that the main frame is at least partially received within the HVAC system and the spindle unit is disposed external to the HVAC system. The filter web extends from the dispensing spindle towards the second end of the main frame and extends back to the receiving spindle, while being at least partially received in the main frame.
