Abstract

An air treatment system having a relatively large capacity yet a relatively small footprint and low sound level. The air treatment system includes a housing defining adjacent vertically extending inlet and outlet chambers. A blower is mounted within the inlet chamber to move air through the system. A generally planar filter is contained within the outlet chamber and is spaced apart from the rear wall of the housing to define a plenum. The rear wall of the housing is curved so that the plenum is tapered to provide uniform pressure over the face of the filter. The system is adapted to rest upon the floor or mount either vertically or horizontal to a wall. Additionally, the system includes a control mechanism that allows the system to run at full speed for a predetermined period of time and then automatically return to its previous speed level.
