Abstract: A frameless EMC air filter for a conductive enclosure includes a body comprising a conductive layer disposed between two filtering layers, the air filtering layers forming a periphery of the body. The frameless EMC air filter further includes one or more bare edge portions that extend outwardly past the periphery of the body. Each bare edge portion is formed by an extension of the conductive layer capable of providing direct electrical contact with the conductive enclosure.

Abstract: A fastener for removably securing sheeting to a support surface, such as an HVAC system or other device. The fastener includes a base, a rare-earth magnet to removably couple the base to the support surface, the rare-earth magnet having an epoxy coating and being capable of securing the base to a pre-selected location on the support surface, and a locking member pivotably coupled to the base and adjustable between a selectable first position and a second position, and wherein the locking member remains in the selected position unless acted upon by a user.

Abstract: A filter assembly for a structure having an air intake, the filter assembly including a filter media that is sized and shaped to cover the air intake. The ends of the filter media are connected by an elastic fastener, such that the filter media and the fastener encircle the structure and are under tension to hold the filter assembly on the structure. The filter media is a web of synthetic fibers, such as a web of fibers woven in a 3-dimensional pattern or a nonwoven mesh.
