As people spend 90% of their time in indoor spaces, indoor air quality is important to protect human health from hazardous particles. A significant correlation was established between particle pollution and respiratory problems. Not to mention that vacuuming surfaces is insufficient to remove all particles from surfaces, and causes resuspension of particles originally deposited. This work presents an experimental approach to measure particle concentrations within an indoor space, equipped with a mixed ventilation system, where supply and return positions were altered. Two different supply-return configurations were tested and particle concentrations were measured. The two configurations were ceiling supply and ceiling return, and ceiling supply and floor return. The particle concentrations were normalized and averaged in the occupied zone of indoor spaces. The results showed the first system, ceiling supply and ceiling return was capable in removing 18.2% more particles than the second system.
