The filtering devices are physical-typed or chemical-typed for filtering the air pollution. The filtering devices include one or more movable filtering devices, and the movable filtering device includes a gas detection device. After the intelligent computation is performed to locate an air pollution location, a control command is transmitted to the movable filtering device selectively and intelligently, and the movable filtering device receives the control command and is moved to the air pollution location. Therefore, the movable filtering device allows the air pollution data to approach to a non-detection state, thus a gas in the indoor space is cleaned to a safe and breathable state.
