Abstract
An exhaust fan for preventing air pollution includes a main body and at least one gas detection module. The main body is configured to form an airflow-guiding path and includes a gas guider and a filtration and purification component disposed in the airflow-guiding path. The gas guider introduces an air convection for guiding an air pollution source contained in an air to pass through the filtration and purification component so as to filter and purify the air pollution source. The at least one gas detection module is disposed in the airflow-guiding path for detecting the air pollution source and transmitting gas detection data.
