Zusammenfassung:	An air flue filtering device preventing superfine particulate matter is used for effectively preventing outdoor fresh air from polluting the indoor environment and guaranteeing the indoor air quality in a passenger station. The air flue filtering device comprises a fresh air pipeline. The fresh air pipeline is provided with a filtering unit. A filter element obstructing the air-passing section of the filtering unit is arranged in the filtering unit. An air inlet and a purified air outlet in the two sides of the filter element are in butt joint with the port of one side of the fresh air pipeline, a differential pressure detector and a superfine particulate matter tester are arranged on the two sides of the filter element respectively, and detection signals of the differential pressure detector and the superfine particulate matter tester are transmitted to a displaying and alarming panel.
