What Is Relative Humidity?
The relative humidity is simply the amount of moisture in the air measured in percentage. Fifty-percent relative humidity means that there's an equal mix of moisture in the air.
High humidity is usually above 55 percent. This happens when the air becomes warmer. Humidity can reach 100 percent or the saturation point, which is also known as dew point. If the temperature drops below the dew point, the air can become over-saturated. This also causes condensation on colder surfaces such as windows and mirrors in the home.
High humidity outdoors during the summer can be uncomfortable. Rain eventually follows in the New England area with a summer storm that may cool the air. A dehumidifier may be necessary during the summer months for indoor comfort.
Humidity Control
Maintaining home humidity at a maximum of 55 percent is most important during the summer season. A dehumidifier prevents mold and algae from building up in corners, especially in bathrooms and the laundry room. This is part of your air conditioning system's humidity control.
A humidifier is usually necessary for balance in winter when your home is heated to 70 degrees or above. The inside humidity level should be adjusted for outside temperatures. If the outside thermometer reads 10 to 30 degrees, the inside humidity level is generally most comfortable between 30 and 40 percent.
