In HVAC systems, what is the primary function of a humidifier?

The primary function of a humidifier in HVAC systems is to increase indoor humidity. Humidity refers to the amount of water vapor present in the air. A humidifier aids in maintaining optimal humidity levels, particularly in dry environments or during winter months when indoor heating can significantly lower humidity levels.

Proper humidity is essential for comfort, health, and the proper functioning of HVAC systems, as overly dry air can lead to issues such as dry skin, respiratory problems, and discomfort in living spaces. By adding moisture to the air, humidifiers help create a more comfortable indoor environment and can also prevent damage to wooden furniture and flooring, as well as reduce static electricity.

While cooling the air, distributing heat, and filtering air pollutants are important functions of various HVAC components, they do not pertain to the primary role of a humidifier.
