A quick attachment feature for a filter includes i) a pair of radially-outward projecting pivots on opposite sides of the filter canister toward a lower end thereof; and ii) a pair of flexible retaining clips also located on opposite side of the canister toward the upper end thereof, each clip in substantial axial alignment along the canister with a respective pivot. The filter can be supported in a bracket including a pair of side walls, each of the side walls including i) a hook-shaped opening dimensioned to receive a respective pivot on the filter, and allow the filter to pivot from an orientation at an angle to the longitudinal axis of the bracket, to an orientation where the filter is substantially axially-aligned with the bracket; and ii) a catch dimensioned to engage and retain a respective retaining clip, when the filter is substantially aligned with the bracket.
