Our stove fine dust filter works with innovative two-phase technology that significantly reduces emissions and enables clean combustion – ideal for private stove owners as well as for distribution through specialist retailers or as an OEM product.
Phase 1: Two Blue Fire catalytic converters reduce gaseous emissions of CO and hydrocarbons – CO by up to 67%. They do not become clogged with dust, which enables consistently efficient operation.
Phase 2: The high-quality Culimeta glass fibre filter reliably reduces even the finest dust particles from the exhaust gas. The stove exhaust gases are effectively cleaned by depth filtration, with a pressure loss of only 1 Pa at room temperature.
A permanently open bypass prevents loss of performance if the filter becomes clogged. Thanks to its compact design in the DN150 exhaust pipe, the system quickly reaches its operating temperature – reducing fine dust and pollutants by up to 42% with every use.
Our system combines a glass fibre fine dust filter with the Blue Fire catalyst for
