hree Andean communities within the Santiago de Chuco province of Peru received two different models of improved cookstoves; one from the Peruvian government and one from a local industry. The impact of these stoves in reducing personal exposures and kitchen concentrations of particulate matter (PM2.5) and carbon monoxide (CO) was evaluated separately in 64 homes (32 in each community) with the use of air monitoring equipment. In one community, 48-hr personal exposure and kitchen concentrations of PM2.5 were reduced by 41.3% and 59.2%, respectively, and 48-hr personal and kitchen CO levels reduced by 69.6% and 77.7%. Corresponding levels in the second community were reduced by 53.8, 70.5, 25.9 and 65.6%. Both stoves were effective at improving indoor air quality in these communities.
