Humidity control refers to the process of managing the moisture levels in the air within a specific environment. This is important for maintaining comfort, preserving materials, and ensuring health. High humidity can lead to mold growth and discomfort, while low humidity can cause dry skin and respiratory issues. Devices such as dehumidifiers and humidifiers are commonly used for humidity control. Dehumidifiers remove excess moisture from the air, while humidifiers add moisture when the air is too dry. Proper humidity levels typically range from 30% to 50%, depending on the environment and specific needs.
