Wood stoves are a major problem. As soon as it gets cold in Germany, air pollution rises from below 5µg/m^3 to 20-100 µg/m^3 and stays there for months (in this particular area).
Keep doing what you need to. Don't feel bad for living. If you have the ability to switch them consider it but realistically it needs to be pushed into law to ban wood burning furnace. Individuals changing isn't enough.
