Before delving into the potential hazards and health risks associated with condensation in dryers, it is important to have a clear understanding of what it is and how it occurs.

Condensation in dryers happens when moist air meets a cold surface (usually the walls of the dryer). The moisture in the air then condenses, forming droplets of water that collect in the dryer drum or vent.

The primary cause of condensation in dryers is poor ventilation. When a dryer is not properly ventilated, the moisture from the clothes being dried has nowhere to go, leading to excessive condensation buildup inside the dryer.

The type of dryer used can also contribute to the occurrence of condensation. For example, ventless dryers (which do not require an external vent) are known to produce more condensation than vented models.

It is important to note that a certain amount of condensation is normal in dryers. However, excessive buildup can lead to a variety of safety and health concerns.

Potential Hazards of Excessive Condensation
