The PRE-FILTER catches the larger particles as room air is drawn through the rear grille. 2. In the IONIZING SECTION of the ELECTRONIC CELL, billions of microscopic particles become electrically charged as they pass through a powerful electric field. 3. COLLECTOR PLATES immediately attract these ''charged'' particles. 4. Finally, an activated CARBON FILTER removes most common odors and fumes as the ''clean air'' is circulated back into the room. By using a four-step process to filter the air of particles, odors and fumes, the Friedrich C-90A provides you with fresh, clean air to breathe and reduces breathing problems for those with allergies and respiratory sensitivity.
