A relative humidity of 30 to 50 percent provides the most comfort for indoor air. Too little or too much humidity can cause problems with the health of the home's occupants and can cause structural problems in the home.
Relative humidity inside the home increases as the actual temperature comes closer to the dew point temperature. The dew point temperature is the temperature at which the air cannot hold all the moisture in it and some of it condenses into liquid.
The ideal humidity range for the inside of a building is between 30 percent and 60 percent, depending on the temperature and time of year. Humidity outside the recommended ranges causes discomfort, property damage and health risks.
Indoor humidity levels should be kept at 50 percent or lower. Keeping humidity down helps to keep mold and spores at bay, and helps to cool the home.
Forty-five percent relative humidity is the comfortable relative humidity level. Below 30 percent humidity, the air feels dry, and above 52 percent relative humidity, the air feels very moist.
The ideal indoor humidity level for a home falls in the range of 35 to 50 percent. This range provides the optimal comfort and health.
Maintaining an indoor relative humidity of approximately 45 percent is the ideal level for the summer months or warmer climates. Colder climates or the winter months require even lower levels, approximately 30 to 40 percent. Indoor air quality is regarded as one of the ...
