What is fine dust?
Fine dust consists of a mixture of tiny, part solid, part liquid or gaseous particles that are smaller than a ten thousandth of a millimetre. Fine dust is not a homogeneous substance but a mixture of the most diverse constituents. These constituents are soot, heavy metals, organic substances, and dioxins. The smaller the diameter of these dust particles, the deeper they penetrate into the lung. There they clog and cause damage to the smallest bronchi and alveoli.

How is fine dust formed?
Fine dust is formed from industrial waste gases, diesel particulates, car exhaust gases, abraded brake lining particles, earthwork and natural processes.

Fine dust from wood firing
Burning wood gives rise to fine dust to varying degrees, depending on the quality of combustion, the fuel and how the firing installation is operated.

Tonwerk storage heating stoves and fine dust
The innovative heating principle underlying our Tonwerk storage heating stoves reduces emissions to well below the thresholds stipulated in Europe and worldwide.
A Tonwerk storage heating stove exhibits a high efficiency and so utilises the energy completely. This low-emission combustion affords an essential contribution to the conservation of clean air levels.

With Tonwerk you are on the clean side!
