Abstract
A filter assembly for use with a commercial air filtration unit. The filter assembly includes a frame, a sorbent material filter, and a primary particulate filter. The frame defines an upstream portion and a downstream portion, with the upstream portion forming a lip. The sorbent material filter is coupled to the downstream portion. Conversely, the primary particulate filter is coupled to the upstream portion of the frame. In this regard, the primary particulate filter defines an inner face and an outer face. Upon assembly, the inner face is adjacent the sorbent material filter and the lip projects upstream of the outer face. During use, the lip provides a receiving surface for installation within a housing, while preventing damage to the filter materials. Further, the filter assembly can be selectively maneuvered to a partially released position relative to the housing whereby the filter assembly hangs freely from the housing, supported at the lip.
