The present experimental study aims to measure the deposition of fine particles on building internal surface coverings. A 125-liter experimental chamber has been built in order to evaluate the loss-rate coefficients of 0.35, 0.53, 0.7, 1 and 2 mu m particles on eight coverings commonly found in buildings (two sheet vinyl, two wallpapers, two woods, one custom- made plaster and one custom- made concrete) under three airflow intensity levels. Results show that, if particle deposition clearly increases with near-wall airflow velocity, the role of the surface three-dimensional roughness is less evident because of the complex topography of real coverings.
