The invention discloses a passive air sampling device with direction controlled by a flying wing and its using method, and relates to the air sampling device and its using method, and belongs to the technical field of organic pollutant environment behavior. The invention aims to solve the problems of long time waste and low efficiency of the existed passive sampler. The passive air sampling devicewith direction controlled by the flying wing comprises a tripod, a bearing, a fixing screen, an absorbing material, a ventilating opening, a horizontal connecting rod, a vertical tail wing, a supporting rod, a horizontal tail wing and a supporting pillar. The method includes steps of making the ventilating opening face to the wind direction, taking off three absorbing materials after 30 days, andthen storing at low temperature; namely, completing the sampling of organic pollutants in the air. The passive air sampling device has the advantages that the ventilating opening is always faced to the wind direction, the air sampling volume is increased and the sampling time is shortened. The efficiency of organic pollutants in the air is effectively improved, at a year-on-year growth of over 5%. The invention is mainly used for collecting organic pollutants in the air.
