Abstract: A framed air filter that includes air filter media and a frame with four frame portions. At least one corner of the frame is a bonded, non-integral corner at which a stabilizing flap that integrally extends from a first frame portion of a pair of neighboring frame portions that meet to form the non-integral, bonded corner, is affixed to an inner sidewall of a second frame portion of the pair of neighboring frame portions.

Abstract: A network interface peripheral device (NIP) may include a network interface for communicating with a network, and an interconnect interface for communicating with a processor subsystem. First buffers in the NIP may hold data received from and/or distributed to peer peripherals by the NIP, and second buffers may hold payload data of scheduled data streams transmitted to and/or received from the network by the NIP. Payload data from the data in the first buffers may be stored in the second buffers and transmitted to the network according to transmit events generated based on a received schedule. Data may be received from the network according to receive events generated based on the received schedule, and distributed from the second buffers to the first buffers. A centralized system configuration entity may generate the schedule, manage configuration of the NIP, and coordinate the internal configuration of the NIP with a network configuration flow.

Abstract: A pleated air filter media with a plurality of continuous-contact reinforcing filaments on at least one face of the pleated air filter. The filaments have locally-thinned bending zones each of which is registered with pleat tip or pleat valley of the pleated air filter media.

Abstract: A pleated air filter media is provided. The pleated air filter media comprises a plurality of upstream linear bridging filaments that are extrusion-bonded to at least some of a plurality of upstream pleat tips of a fibrous web, and a plurality of downstream continuous-contact filaments that are extrusion-bonded to a downstream face of the fibrous web. Methods of making and using the same are also provided.

Abstract: A kit that includes a base with a floor and four edges; a cover with a ceiling and four edges; and, four side panels, at least one of which is a framed air filter. The kit may be nestable. The kit is assemblable into an upwardly-open, horizontally-closed air-filtration assembly. The floor of the base may include multiple through-cuts and hinged connections that define multiple areas of the floor that are rotatable upward to provide multiple upwardly-protruding tabs; the ceiling of the cover may include multiple through-cuts and hinged connections that define multiple areas of the ceiling that are rotatable downward to provide multiple downwardly-protruding tabs.

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.

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 rigid, channel-framed, pleated air filter, with a plurality of linear bridging filaments on at least an upstream face of the pleated air filter media of the filter.

Abstract: The present disclosure relates to air filters. More particularly, it relates to air filters including pleated filter media that can be uniformly expanded and contracted. In some embodiments, the air filters are adjustably sized air filter systems. In some embodiments, the air filters can be used in a window opening.
