Health - in addition to the comfort issues, dry air can be the ideal atmosphere for the growth of bacteria and viruses. Viral infections such as a cold or flu are easier to contract or pass to others under low humidity conditions. Overly dry air causes itchy, cracked skin, eye irritation, stuffy nasal passages. These Efficiency - As the moisture from indoor air evaporates, the temperature in your home feels colder. In the winter, that means you will turn up the thermostat to feel comfortable. As a result, your system will use extra energy. By putting moisture back into the air, a humidifier allows you to remain comfortable at a lower heating temperature for lower energy use and greater operating efficiency. ![]() Honeywell TrueClean Air Filter |
