The ideal dew point in a house can vary, but generally, a dew point between 40°F and 50°F (4°C and 10°C) is considered comfortable. It's essential to control the dew point since it's directly related to the house's relative humidity. A dew point above or below the comfort range may lead to issues like mold growth or dry skin. The Dew Point Meter 602 Series can help monitor and maintain the perfect dew point in your home.
