Ventilation plays a crucial role in maintaining and improving indoor air quality. One of its primary functions is to dilute indoor pollutants that may accumulate due to various activities such as cooking, cleaning, and the use of indoor appliances. By introducing fresh outdoor air into a space, ventilation helps to lower the concentrations of indoor contaminants, making the air healthier to breathe.

In addition to reducing pollutants, effective ventilation can also help manage humidity levels, although it does not do so exclusively. By balancing indoor humidity through proper airflow, it can prevent issues such as mold growth and discomfort, which are often exacerbated by high humidity.

Bringing in fresh air not only refreshes the indoor atmosphere but also contributes to a healthier living environment, promoting overall well-being. Therefore, ventilation is vital for maintaining good indoor air quality by effectively diluting harmful substances and providing a constant supply of clean air from outside.
