The heat recovery ventilator is now advanced with filter apparatus mounted, and it can operate the air cleaning mode; filters 100% recirculation indoor air when the outdoor particle matter(PM) concentration is severe. When the air cleaning mode is operating, not only the filter but also the ventilator shell and ducts affects the concentration due to the leaks. In this study, to estimate the PM removal efficiency of the ventilator and connected ducts(ventilation system), two field experiments in a apartment were conducted. In the first experiment the ventilation system was turned off, and it was to estimate the natural decay rate. Second experiment was to estimate the removal rate and the penetration coefficient, and the ventilation system was turned on. After collecting the outdoor and indoor PM concentration data from each experiments, the removal efficiency and penetration coefficient was estimated on the basis of the particle mass conservation law. The removal efficiency of the recovery ventilator was turned out to be about 1(100%), and the penetration coefficient (P) was about 25~30% (P of the building shell) when the system was turned off but it (P of the building shell and ventilation system) reduced to about 0% when the system was turned on.
