House dust contamination has recently become an important issue in the residential indoor environment. This study evaluated ventilation systems for removing house dust efficiently in a full-scale residential room. Experiments and simulations were performed to investigate diffusion and deposition of house dust by different ventilation systems. Riboflavin particles were used as the house dust. Two kinds of ventilation systems were considered, namely ceiling exhaust and slit exhaust.
