Abstract
The present invention provides an air treatment device including a housing, an emitter electrode configured within the housing and a collector electrode configured within the housing and positioned downstream from the emitter electrode. The device preferably increases the ions produced for a start up period after the device is initially turned on, wherein the device automatically decreases ion production after the desired period. The device preferably includes a first and second voltage source to selectively increase and decrease voltages applied to the emitter and/or collector electrode to adjust the ion production. In one embodiment, the device includes a voltage controller to selectively adjust the voltage provided by the voltage source for the start up period and normal operation.
