Controlling indoor humidity is very important. Usually, the air inside a home is drier than a desert. Dry, indoor air is often the culprit for such common problems as itchy or cracked skin, eye irritation, dry nasal passages, and damaged home furnishings. Dry indoor air can also increase the possibility of catching cold and flu viruses and can reduce the efficiency and effectiveness of the heating system. All of these problems can be alleviated with the help of a humidifier. The humidifier will put moisture back into the indoor environment, so homeowners can relax in warm, soothing comfort. Also, because humidified air feels warmer, using lower thermostat settings may be possible for added energy savings.
