Abstract
This research study examined the degree to which residents are exposed to PM2.5 concentration levels due to wood smoke using several instruments, including six Dusttrak II 8530, a Dylos DC1700 and a UNI-T. The parametric variations in this study included distance from the woodstove, height above floor level, duration of time the woodstove door remained open for refueling, time between refueling stages, and the effectiveness of various types of air purifiers in reducing PM2.5. An extensive instrument calibration and error analysis were also conducted as a way of evaluating the accuracy of the data obtained with different instruments. The results showed that the PM2.5 distribution varies with distance from the woodstove and height above floor level. The results also showed that the use of air purifiers incorporating HEPA filters were most effective in reducing PM2.5. This research study adds to the body of knowledge and has practical implications in the monitoring and mitigation of indoor levels of PM2.5.
