Which of the following contributes to moisture buildup in housing?

Inadequate ventilation is a significant contributor to moisture buildup in housing. When a home lacks sufficient airflow, it can trap humidity and moisture produced from everyday activities such as cooking, showering, and even breathing. This trapped moisture can lead to a variety of issues, including mold growth, structural damage, and a decrease in indoor air quality.

In contrast, proper ventilation systems, dehumidifiers, and regular air circulation are designed to manage humidity levels effectively. Proper ventilation allows moist air to escape and fresh air to enter, helping to reduce overall humidity. Dehumidifiers actively remove moisture from the air, further preventing the accumulation of humidity. Likewise, regular air circulation ensures that moist air does not become stagnant, promoting a healthier living environment. Together, these methods help mitigate the risk of moisture buildup, while inadequate ventilation directly promotes it.
