How the C-90B
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
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-90B
provides you with fresh, clean air to breathe and reduces breathing problems
for those with allergies and respiratory sensitivity.
