Occasionally, the pre-filter will require cleaning. To clean the pre-filter, remove the pre-filter and shake out or brush off the accumulated dust and lint. If this is not adequate, a vacuum may be used or the pre-filter can be cleaned with an all purpose detergent based cleaner to remove tobacco smoke and cooking grease stains. A thorough rinsing is required after each cleaning. After cleaning, allow to dry and reinsert. When the filter becomes worn or damaged, it should be replaced.
1. The C90A 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. The C90A has been rated the #1 air cleaner in the US.
