Friedrich C-90, C-90A and C-90B Air Cleaner Replacement Carbon Post FilterCarbon post filter removes allergens, odors and other impurities from the air; for use with
Friedrich C-90, C-90A and C-90B air cleaners. Your filter should be
replaced every three months. Occasionally, this carbon
filter will need cleaning. Use a stream of air or a vacuum to remove the
dirt. However, the chemical and odor absorption capabilties cannot be restored.
When the carbon filter can no longer remove odors from the air, it should
be replaced. Often, just a good cleaning will suffice.
C90A Features:
1. The C90 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 by a leading consumer magazine.
