Dry air in your home can make your throat and skin feel dry and scratchy, cause or aggravate respiratory problems, dry out nasal passages and make you more susceptible to colds or the flu. Although winter weather is often blamed for these problems, another major cause is dry air produced by artificial heating with forced hot air furnaces. Humidifying your home to provide proper moisture levels will help alleviate these symptoms.

Controlling humidity can also help you save money on energy bills. The heat our bodies feel is a combination of temperature and humidity. In other words, the more humid the air, the warmer you feel. If you add humidity to dry, heated air in the winter, you can set your thermostat lower and still be comfortable.
