The Mesa Personal Impactor is a development of the Environmental Science and Engineering Group at the Harvard School of Public Health. It is a group of four impactors designed to be worn on the person in order to closely gauge their exposure to PM10 PM4 or PM2.5 concentrations at two different flow rates. This design eliminates the bias found when particles impact dry surfaces.
