Airborne particles and odors are removed from
air passing through the unit by the process of
electrostatic precipitation and the revolutionary
post filter which combines antimicrobial
treatment and activated charcoal.
The air around you is filled with thousands of particles of air
pollution. Some of the pollutants - dust, pollen and lint are visible to the naked eye, but most of
the pollutants - smoke and bacteria, to name a few, are microscopic in size.
Polluted air enters the unit through the front of the air cleaner. The fan pulls in dirty air and the
pre-filter traps large particles (hair, lint, etc.). The smaller particles (dust, smoke, pollen) in the
dirty air receive a positive electrical charge as they pass through the ionizing section. The
positive charged particles then enter the collecting section which uses a series of alternately
charged aluminum plates to attract and retain the particles. It works like a powerful magnet
and the particles remain there through natural adhesion until removed by the washing process.
The air then passes through the post filter that helps control microorganisms and remove
household odors. Next, the negative ion generator freshens stale air. Finally, clean air passes
back into the room through the top grille.
