The Aprilaire 800 Steam Humidifier adds moisture to your home by passing steam through a dispersion tube connected to your duct system. Steam is created by heating water in an internal tank. A digital display control will help you monitor and adjust the desired humidity. The Aprilaire 800 features a “DUAL SENSOR 24/7 AUTO MODE” that will measure the relative humidity inside your home. The fans will automatically turn on when the humidity drops below the set point.
