How the

QuietFlo

Air Purification System Works

As the air is pulled into the purifier, the activated carbon pre-filter absorbs odors and catches
large particles. Then, the air travels through the HEPA filter where the smaller particles are
collected. Then, the ionizer releases negative ions into the air that attract positively
charged dust, smoke, and pollen particles. Finally, the clean, purified air is released
back into the room.
