The process of exchanging indoor air for outdoor air is known as what?

The process of exchanging indoor air for outdoor air is known as ventilating. Ventilation is a critical component of indoor air quality management, as it helps to remove stale air, odor, and pollutants from indoor spaces while introducing fresh air from outside. This exchange not only improves air quality but also helps regulate temperature and humidity levels within a building, contributing to a healthier and more comfortable indoor environment.

In contrast, cooling refers specifically to lowering the temperature of indoor air, while heating focuses on increasing it. Filtering involves removing particulates and impurities from the air but does not encompass the act of exchanging air between indoors and outdoors. Therefore, ventilating is the term that accurately describes the process of air exchange.
