Patent ID: 7318856

Claim:
An air treatment apparatus, comprising: housing having a bottom, a top, first side wall and a second side wall, the housing having: (a) an axis extending between the bottom and the top; (b) an inlet located adjacent to the first side wall; and (c) an outlet located adjacent to the second side wall; an elongated emitter electrode supportable by the housing so as to extend substantially parallel to the axis; an elongated collector electrode supportable by the housing so as to extend substantially parallel to the axis, the collector electrode being movable between a first position and a second position relative to the housing; a voltage generator operably coupled to the emitter electrode and the collector electrode, the voltage generator being operable to produce an electric field, the electric field being operable to cause a germicidal effect; and at least one air movement mechanism supported by the housing, the air movement mechanism configured to cause air to move from the inlet through the outlet along a path which is substantially perpendicular to the axis.
