  • Publication number: 20230277971
    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.

  • Publication number: 20230277970
    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.

  • Publication number: 20210187425
    Abstract: An air filter device including an air filter unit and an expansion unit. The air filter unit includes a filter media assembly maintained by an outer frame assembly. The outer frame assembly defines exterior length, width and depth dimensions of the air filter device in an initial state. The expansion unit provides one or more of an expanded length, width or depth in an expanded state of the air filter device. Portions or an entirety of the expansion unit can provided apart from the air filter unit in a deliver condition of the air filter device, or can be assembled to the air filter unit prior to delivery to a user. The air filter devices of the present disclosure are useful with a wide variety of differently size air handling devices, able to readily seal with an air handling device compartment via the expansion unit.

  • Patent number: 10981099
    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.
