Quizplus · Accepted Answer

Bypass humidifiers work by diverting a portion of the heated air from the furnace and passing it through a moistened pad or filter, which adds humidity to the air. Since the heated air is already moving through the furnace, a separate fan is not needed to push the air through the humidifier.
