Mesafint Molla Adane e outros, 2021 · Environmental Health and Preventive Medicine
Distributing the Mirt improved biomass cookstove reduced average indoor PM2.5 concentrations by approximately 343 μg/m3 over four follow-up rounds compared to traditional cookstoves.

Contexto
What changed: Households in treatment clusters received free installation and demonstration of the Mirt biomass improved cookstove for baking injera. Comparison: Control households continued using open-burning traditional cookstoves. Limits: The intervention was unblinded, relied on 1-hour kitchen measurements rather than 24-hour personal exposure, and particulate sensors detected sizes down to only 0.5 μm.
