Product Overview
Dry air in the home not only makes you uncomfortable with itchy skin, nose bleeds, and static electricity, but low humidity in the home can make you susceptible to colds and upper respiratory infections. One solution is to use an Aprilaire whole house humidifier which can deliver the perfect amount of humidity, 24 hours a day, seven days a week.
