Abstract

An air treatment system includes a housing having a from cylindrical chamber and a rear rectangular chamber, the front and rear chambers being separated by an internal wall. The front chamber is provided with a series of outlet vents, the rear chamber is provided with a series of inlet vents, and the internal wall is provided with a series of interchamber vents. A pair of electrically-powered cylindrical fan blades are disposed within the front chamber and are used to draw air into the rear chamber through the inlet vents, to move the air from the rear chamber to the front chamber through the interchamber vents and to exhaust the air from the front chamber through the outlet vents. A plurality of ionizer needles are also disposed within the front chamber. The rear chamber is shaped to include a generally rectangular reservoir. The air treatment system also includes a water tank removably mounted within the rear chamber for use in supplying water to the reservoir. The air treatment system additionally includes a pair of alternative filter assemblies which are positionable in the reservoir. The first filter assembly, which is intended to be used when the reservoir is filled with water so as to provide both air purification and humidification, includes a purification component and a humidification component. The purification component includes an electric filter and an activated charcoal filter, both of which are housed within a metal frame. The humidification component includes a honeycomb-shaped wicking filter and a pair of aluminum frames, the frames being mounted on the front and back sides of the wicking filter. The second filter assembly, which is intended to be used when water is not present in the reservoir so as to provide only air purification, includes a HEPA filter and an activated charcoal filter, both of which are housed within a cardboard frame.
