(Replaces GF900DMM)

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® Humidifier will improve your comfort indoors and maintain a healthy environment so you can breathe a little easier.
