Abstract Introduction & Purpose: Indoor air quality, particularly in health care facility, is important. One of the most important factors affect the air quality is aerosols due to carrying microorganisms and deposit in the respiratory tract. Therefore, the purpose of this study was to measure the concentration of suspended particles in outdoor and indoor ‎of Dena hospital and determine the relationship between these parameters.‎ Methods: A cross-sectional study was done in Dena hospital in Shiraz in 2012. 315 samples were collected for analysis. Sampling was performed by using a sampler Aerosol Mass Monitor, Model GT-331, made in Japan to ‎measure the particle concentrations of PM10 and PM2.5. To compare the concentration of indoor suspended particles ‎in air in different wards and outdoor particle, t-test was used. Then the data ‎were analyzed using SPSS version 16. Results: Results showed that average PM10 in the air in hospital wards as well as all the outdoor air is significantly less than the standard 24-hour WHO and the standard 24-hour USEPA (p<0.001). The Significant relationships were seen for the average concentrations of PM2.5 in all the sampling sites ‎and the 24-hour standard of WHO and USEPA (p<0.001‎)‎. conclusion: The concentration of particle matter in indoor air in Dena hospital was less than the outdoor air that indicate the proper functioning of air-conditioning systems inside the different department of the hospital.
