Ventilation is the process of exchanging air in a closed space. This can be done by opening windows and doors, or by using fans or air conditioners.
Ventilation is important for keeping the air fresh and clean. It can also help to remove harmful pollutants from the air, such as smoke and dust.
Ventilation is especially important in places where people spend a lot of time, such as homes, schools, and offices. It can help to prevent the spread of germs and diseases.
