I live in an area were most of the houses (+2 flats) use pellet (also in summer for hot water production). The air quality drastically dropped. It really "burns" the lungs some days.

I suspect that:

- combustion is not properly done most of the time and there is no need to have filters in the chimney.

- some pellets must not contain only "clean" wood

We are only waiting to move to a place with single familly houses because (in my area) they mainly migrate from petrol-gaz to solar energy (thermal) and heat pump (water-water).
