The particle deposition on indoor surfaces have lately received great attention due to increasing concern about the effects of particle exposure on human health. In this study, we developed an easy and low-cost method to measure the deposition amount of different-size particles, and we evaluated this method through the particle concentration measurement and theory calculation. A clean charge coupled device (CCD) chip was exposed to air and received the deposition of particles. After a sedimentation period, the images generated from the CCD were analyzed, and the amounts of each particle type (> 2 μm) were identified based on their different pixel sizes. We also measured the concentrations of particles with different sizes around the chip during the sedimentation and compared the relationship to the number of settled particles. The results show that this method can obtain the particle deposition amount during a period and that there is a positive correlation between the deposition amounts and the particle number concentrations.
