Ventilation is the process of bringing fresh air into an indoor space and removing stale air. It is commonly used in buildings and homes to maintain air quality, prevent indoor pollution, and regulate temperature and moisture levels. Ventilation can be achieved through a natural or mechanical system, such as opening windows or using air ducts and fans. Proper ventilation is important for the health and comfort of occupants and can also improve energy efficiency and reduce the risk of mold and other indoor pollutants.
