A recent study in Malawi showed that switching from a three-stone fire to a Chitetezo Mbaula improved stove reduces the quantity of particles emitted by 46% and carbon monoxide by 44%. A well-tuned stove can reduce firewood consumption by up to 80%.

Most Malawians do not have access to electricity. The only way they can soften their carbohydrates in order to avoid starvation is by burning wood to boil water. The Chitetezo Mbaula stove is hand-made using local materials, fostering local ingenuity and self-reliance. The stove project provides income to over 2,000 people (mostly women in rural areas) to manufacture and promote smoke-reducing cookstoves.
