Abstract: It is all around us, but unless there is a problem, we usually do not concern ourselves with what is in the air that we breathe. In both indoor and outdoor environments, poor air quality can greatly impact our health and well-being. Two important indicators for air pollution measurement are small particulate matters (PM) of 2.5 microns or less (PM2.5) and volatile organic compounds (VOCs). They are, for example, emitted in households by fireplaces and candles during combustion processes. Everyday objects such as cleaning supplies, furniture, or textiles can also emit VOCs. This article provides insights into new PM2.5 and VOC sensing technologies that enable personal air quality monitoring to improve people’s health and well-being.


Keywords: Air quality measurements, VOC sensor technology, PM2.5
