Research Abstract	Soil filter deodorization has been facing the improvement of soil filter because its performance of ventilation and deodorization varies easily with external environment. In this study, a precise measurement system was developed to determine the gas permeability of the soil filter in the ventilation. A complicated relationship between gas permeability and soil moisture content was revealed by the measurement system. The structural feature of the soil filter which satisfies both the gas permeability and absorbability was discussed by the microscopic morphological observation and the mass transfer simulations.
