A fan coil media cabinet for use with a fan coil unit. The cabinet includes an open-sided inner liner having co-joined top, bottom, back, and front panels. The inner panel is mounted within an outer shell having top, bottom, and back walls that are located adjacent to the top, bottom, and back walls of the outer shell. The outer shell contains a ledge that extends about the inner periphery of the shelf upon which the inner liner is seated. The width of the outer shell walls is greater than that of the inner liner panels so that the walls extend outwardly to one side beyond the inner liner. In assembly, the extended wall sections of the outer shell are mounted in contiguous relation with the return inlet of the fan coil and are fastened thereto to create a rigid structure.

An expandable media filter structure is composed largely of biodegradable materials and is environmentally disposable. A plurality of pleated panes are interconnected at their edges so as to be collapsible for storage and shipping purposes but expandable for installation and use. A plurality of ribbons are ultrasonically welded to each of the panel edges, with the ribbon portions between edges being of substantially equal lengths, thereby maintaining equal spacing between the panel edges when the filter is in the expanded condition but allowing an easy collapsing of the filter for storage. Forming a part of the disposable filter are pair of end plates, with each being adhesively attached to an end panel and having a pair of slots formed near their ends for attachment to a nondisposable support structure. The end panels are formed of multiple layers of paperboard which are adhesively bonded and compressed into a U-shaped structure that rigidly supports the filter in its expanded condition. The nondisposable support structure includes a pair of molded plastic side caps that fit over the respective ends of the filter panels and the end plates. Each side cap has a pair of flanges at its opposite ends which act to maintain the filter in its expanded condition when the end pates are placed in abutting position therewith. Each side cap also includes a boss which fits into a respective end plate slot to hold the end plates in their installed positions within the side caps.
