The relative humidity of the Sahara Desert is 25% and Death Valley is 23%. In the winter months, the average heated home can have a relative humidity AS LOW AS 13% to 16%.


An Aprilaire Whole-House Humidifier is installed directly to your central new or existing heating and cooling system. Humidity is introduced into your home’s air in the form of water vapor, which prevents minerals from entering the air in your home and potentially into your lungs. The resulting humidified air is then distributed via your heating and cooling system ductwork throughout your home.
