    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.

    The 400 model comes with a wall mounted Manual Control which displays the relative humidity levels, operation status and any service needs. This Bypass unit uses 100% of the water, and the evaporative technology eliminates the need for a drain. Adds up to 17 gallons of moisture per day into the air.
