This chart helps you determine indoor 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!

Skuttle humidifiers can restore a home's relative humidity to a healthier, more comfortable 30-to-50 percent range.
