FAQ

The stove fine dust filter is suitable both for private individuals who want to continue operating their wood-burning stove in their own home in an environmentally friendly and legally compliant manner, and for specialist companies, chimney sweeps and stove builders who offer retrofit solutions for their customers.

Emissions are reduced in two stages. First, gaseous emissions such as carbon monoxide (CO) and organic gaseous hydrocarbons (OGC) are reduced in the direction of flow through the use of sponge ceramic catalysts. In the second stage, particulate matter is reduced by means of a glass fibre filter stack, which ensures particularly efficient separation of the finest particles thanks to its depth filter effect. Further information on how the particulate filter works can be found in the operating instructions.

The filter system operates with two-stage filtration, in which emission reduction is divided into two independent phases: the reduction of gaseous emissions and particle filtration. Since both phases function separately, the cleaning intervals are also optimally adapted to their respective requirements.

If approval can be granted by the chimney sweep (regulations vary from state to state), then the existing stove can continue to be used without any further time restrictions.

The tests were carried out with firewood in accordance with EN 16510-2-1.

The chimney sweep checks whether the filter is suitable based on the technical system data and issues an approval for the fine dust filter.

Die Schwammkeramik-Katalysatoren sollten abhängig von der Einsatzfrequenz regelmäßig visuell überprüft werden. Falls erforderlich, kann die Reinigung durch Absaugen oder Abfegen erfolgen.

The fine dust filter stack should also be visually inspected at regular intervals. If the filter is saturated, it should be cleaned by burning it off. Weekly cleaning is recommended for regular operation.

Detailed recommendations on cleaning intervals can be found in the operating instructions.

The filter stack should remain in the combustion chamber’s glutathione atmosphere for at least 60 minutes; ideally overnight – not in an open fire!

The catalysts should be replaced after approximately four heating periods (approx. 4,000 operating hours) and the filter stack after one period.

No.

The easiest way to order the filter is directly from our shop. Alternatively, you can also purchase it from a stove retailer, DIY store or your chimney sweep.
