Artificial ventilation in the home is achieved through

Artificial ventilation in the home is achieved through air conditioning or through the use of mechanical ventilation systems, such as exhaust fans or ventilation fans. These systems work by removing stale air from the home and replacing it with fresh air from outside. This helps to improve indoor air quality and reduce the levels of pollutants, such as dust, mold, and other allergens, that can accumulate in the home. Doors and windows can also contribute to ventilation in the home, but they are not typically considered to be a primary means of artificial ventilation. Perforated fancy blocks and chimneys are not typically used for ventilation in the home.
