Chimney fan solves your smoke problems and halves particle emissions


BlueChimney is a chimney fan that solves the problems with smoke – inside as well as outside your house – when using your woodburning stove. It also makes it very easy for you to light the fire and you avoid soot on you glass as well.
BlueChimney makes it possible to reduce particle emission from your woodburning stove by more than 50%. Using BlueChimney on all chimneys with inadequate draft in Denmark will reduce the particle emission by more than 10.000 tons per year and prevent early deaths by more than 200. Applying the same ratios for North Europe will reduce particle emission by 500.000 tons annually and save early deaths by more than 10.000.
