A common misconception of a coal stove is that it is dirty. It can be. It is all in how you handle your coal and your ashes. Keep the coal damp before you dump it into the hopper. This will eliminate any black dust. Pull your ash pan out of the stove half way, slowly, and mist the top of the ashes with water.

An anonymous reader writes: Burning fossil fuels kills more than 1 million people ever year, according to a new study that examined the worldwide health effects of fine particulate pollution, also known as PM2.5. Coal, which produces sooty, particulate-laden pollution, is responsible for half of those deaths, while natural gas and oil are responsible for the other half.
