What is one primary function of a ventilation system?

A primary function of a ventilation system is to ensure proper air circulation and remove stale air. This is essential for maintaining indoor air quality and comfort in spaces like homes, offices, and other buildings. The circulation of fresh air helps to dilute indoor pollutants, reduce humidity levels, and prevent the buildup of harmful contaminants. Stale air, which can come from cooking, cleaning, or human activities, can lead to discomfort and health issues if not adequately managed.

While energy consumption, filtering outdoor pollutants, and controlling indoor temperature are related aspects of a building's overall comfort and environmental management, they are not the primary focus of a ventilation system. The main goal is to facilitate optimal airflow, thereby improving both air quality and occupant well-being.
