    摘要： A hand vacuum cleaner having a front end and a rear end positioned in a rearward direction rearward of the front end is described herein. The hand vacuum cleaner includes a dirty fluid inlet, an air treatment member downstream of the dirty fluid inlet, a pre-motor filter positioned in a pre-motor filter housing downstream from the air treatment member, a suction motor downstream of the pre-motor filter, an air flow path extending from the pre-motor filter to the suction motor, a clean air outlet downstream of the suction motor, and a handle. The pre-motor filter has a longitudinal length in the rearward direction that is longer than a transverse length in a direction transverse to the rearward direction. The pre-motor filter housing has first and second rearwardly extending pre-motor filter housing sidewalls and the pre-motor filter has first and second rearwardly extending pre-motor filter sidewalls that are positioned transversely inwardly of the pre-motor filter housing sidewalls. The pre-motor filter sidewalls are an upstream face of the pre-motor filter and the pre-motor filter has an inner cavity that is downstream of the upstream face.
