Model 1137 Humidifier Legacy Series Humidifier

We spend most of our days indoors. It is important to control the indoor relative humidity to maintain a comfortable and healthy indoor air environment.

Very low humidity in your home in winter can result in dry, itchy skin or dry sinuses and nose. Dry skin can crack and peel and will look unattractive and can lead to infections. Dry noses and sinuses may lead to a clogging or swelling and closing of the air passages and cause breathing difficulty at night. Choosing a GeneralAire Legacy Humidifier will improve your comfort indoors and maintain a healthy environment so you can breathe a little easier.

  • A portion of the heated air from the furnace passes through a water-soaked pad where it absorbs additional moisture and then returns for distribution throughout your home.
  • Water is metered into the KineticFlo® Trough and dispersed uniformly across the pad. Unevaporated water drains from the bottom of the unit to eliminate mineral build-up.


  • MHX3C (Included) humidistat is included. 
  • Fan-powered unit mounts easily on the warm air plenum and delivers 21.3 GPD.
  • Evaporator pad replacement number 990-13.
  • Lead times may vary & may be shipped directly from the MFG.
