What is the primary purpose of ventilation in a home?

The primary purpose of ventilation in a home is to improve indoor air quality. Proper ventilation is essential for ensuring that fresh outdoor air circulates throughout the living spaces, which helps to dilute and remove indoor pollutants such as carbon dioxide, volatile organic compounds (VOCs), moisture, and other contaminants. This exchange of air is vital for maintaining a healthy indoor environment, as it reduces the buildup of harmful substances and contributes to overall comfort and health for the occupants.

While reducing heating costs, decreasing humidity levels, and providing additional heating can be associated with ventilation practices, these are not its main objectives. Effective ventilation systems primarily focus on enhancing the quality of the air we breathe indoors, which is crucial for safety and well-being.
