ABSTRACT:
A room air treatment system includes a housing or cabinet defining a filter chamber and a blower chamber. A blower, disposed within the blower chamber, is connected to the filter chamber by a duct. Positioned within the filter chamber is a HEPA filter and activated carbon or charcoal filter assembly. The housing defines an air inlet covered by a prefilter and an air outlet within which a louver assembly is disposed. A pivotal bail or generally U-shaped rod engages a generally rectangular filter retaining frame to sealingly retain the filter stack within the filter chamber. A control system is included for controlling operation of the blower motor.
