Do I need a Humidifier?

The chart below helps you determine your home's relative humidity. For example, when the outdoor temperature is 10 degrees above 0, and outdoor relative humidity is 70 percent, a home heated to 72 degrees has an indoor humidity level of only 6 percent—much drier than the 25 percent relative humidity of the Sahara Desert!
