Humidity Control for Atlanta Homes | Best Pick Reports
Humidity is the amount of water vapor in the air. Low humidity
indicates dry air, while high humidity indicates moist air.
Unfortunately, Atlanta experiences extreme humidity swings from season
to season. For example, the humidity inside an Atlanta home can range
from as low as 21 percent in the winter to as high as 70 percent in the
summer. Since the average humidity in the Sahara Desert is 26 percent,
during the winter many Atlanta residents live in conditions drier than
a desert. Experts recommend a winter humidity of 35 percent or higher
and a summer humidity of 50 percent or lower.
Too little humidity dries out the skin, makes you feel cold or chilled even at
relatively high room temperatures, and causes wood to shrink. Shrinking
wood causes furniture joints to loosen, cracks between crown molding
and the drywall, and cracks between boards in wood floors. Too much
humidity causes mold, mildew, and odors, and it
also warps furniture and wood floors. Dust mites thrive in high humidity but
perish in humidity lower than 50 percent.
The task of controlling humidity is accomplished in two
primary ways. To add humidity during the winter, a device called a
humidifier is installed in your home’s central heating and air
conditioning system. A whole-house automatic humidifier introduces
humidity into the home in the form of water vapor. The vapor is added
to the air as the air circulates through the system. A standard central
air conditioning unit removes some of the humidity during the summer
when it is running. However, in order to maintain a relative humidity
of less than 50 percent, an automatic whole-house dehumidifier, used in
conjunction with your air conditioning system, is often required.
