Abstract
A filter includes (i) a filter body, (ii) a front cap associated with a first end of the filter body and coupled to and receiving smoke from a vacuum hose, (iii) a back cap associated with a second end of the filter body and having a filter exhaust sized and shaped to associate with and communicate suction from a smoke evacuation system, (iv) a compressed carbon reservoir disposed within the filter body between the front cap and the back cap, and (v) a flexible porous barrier disposed on at least a first side of the compressed carbon reservoir. The compressed carbon reservoir is under a compressive bias by the flexible porous barrier that transitions from a flexed state to a partially relaxed state in response to the compressed carbon reservoir reducing in volume.
