The trial will be conducted in rural Malawi.
150 villages will be randomly assigned to an intervention or control group.
In the intervention villages, all households with a child up to the age of 4.5 years will receive two Philips fan-assisted stoves to fully replace their traditional cooking methods (mainly open fires).
In the control villages, all households with a child up to the age of 4.5 years will continue with their traditional cooking methods.
Included villages will stay in the study for 2 years.
The main outcome of interest is pneumonias in children under 5 years of age.
Other outcomes include measures of air pollution and economic and social impacts of the stoves.
