Details: The SKUTTLE 55-ud under duct humidifier works with your furnace to distribute humidified air throughout your home. It is designed to mimic nature's process of warm air evaporation with the help of a porous evaporator pad. As warm air from your furnace passes over the evaporator pad, water evaporates evenly into the warm air stream. Your heating system then circulates the humidified air throughout your home. Using SKUTTLE 55-ud regularly can restore your home's humidity to a healthier and more comfortable 30 to 45 percent.
