Abstract Cooking using biomass fuels, such as wood, charcoal, or animal dung, is a source of indoor air pollution and causes negative climate impacts, health problems, and premature death in many areas of the developing world. Ethiopian families use charcoal stoves indoors in both rural and urban areas, causing detrimental health effects as well as deforestation. While more efficient cookstoves have been made, they are far too expensive to be practical for most people in Ethiopia. The Carleton College cookstove project seeks to create an affordable stove that will heat efficiently, have reduced emissions, and be viable for Ethiopians to use. We have evaluated seven different Top-Lit Updraft stoves in a controlled cooking test and water boiling test, investigating fuel use, PM 2.5 concentrations measured using TSI DustTrak DRX instruments and Aircasting AirBeam instrument inside and outside of an experimental test kitchen, and aerosol particle composition measured with a TSI Aerosol Time-of-Flight Mass Spectrometer. The various stoves’ performance was compared to a well-characterized, commercially available stove, and performance and particle composition information will be presented.
