HOW IT WORKS
Dirty air is drawn through the front grill and passes through a 3-stage
cleaning system (See Fig. 1).
Stage 1
The washable Pre-filter prevents larger particles from passing through into
the Collecting Cell.
Stage 2
The Collecting Cell has a 2-part function. First, the dirt particles not trapped
by the Pre-filter are electrically charged by fine ionizing wires. Second, the
charged particles are then attracted to and collected by the Collector Plates.
Dirt, pollen and smoke particles are captured and held by the collector
plates in the cell. These electrically grounded plates hold the dirt until the
cell is removed and washed.
Stage 3
The Ionizer, when turned ON, adds negative ions to the exiting stream of
clean air. This function provides additional air freshening and revitalization.
