What is the main purpose of ventilation in indoor spaces?

Ventilation plays a crucial role in maintaining indoor air quality by diluting indoor pollutants and supplying fresh air. This process helps to remove contaminants such as carbon dioxide, volatile organic compounds, and other harmful substances that may accumulate in enclosed spaces. When fresh outdoor air is introduced into an indoor environment, it mixes with the indoor air, effectively lowering the concentration of these pollutants. This exchange is essential for ensuring that occupants breathe cleaner air, promoting health and well-being.

While other functions related to indoor air management exist, their primary objectives diverge from the main purpose of ventilation. For example, maintaining consistent temperatures is often more associated with heating and cooling systems rather than the ventilation itself. Filtration may focus on particulate matter but does not address gas-phase contaminants or the need for fresh air. Ventilation's primary aim centers on enhancing air quality by ensuring a steady flow of clean air into indoor spaces, making it vital for health and comfort.
