Filter device

Abstract

A filter device includes a frame, a filter unit, and at least one intermediate component. The frame has two opposing support frames. The filter unit includes a frame and a filter material, with the frame positioned between the two support frames and the filter material disposed within the frame. The at least one intermediate component is disposed between one of the support frames and the frame, wherein the at least one intermediate component is bonded to one of the support frames using a thermoplastic material, and the at least one intermediate component is bonded to the frame using an adhesive material. When it is necessary to separate the filter unit from the support frame, the thermoplastic material is heated to create a sliding contact between the frame and the support frame, allowing the at least one intermediate component to be extracted and the filter unit to be easily separated from the frame, thereby enabling the disassembly or recycling of the filter unit.
