Over several months, we conducted tests at two companies in the wood-based materials industry. The results were even better than expected. It became clear that the filter handled an extremely dusty air volume of over 500,000 m³/h exceptionally well. Formaldehyde was filtered out by 95%. Regarding carbon, it was evident how well the biological system adapted to the exhaust air over time. Here too, the measurement results were outstanding.

Evaluation of Measurement Point 

After a suitability test, our filter system has met all legal limit values. In the test conducted on November 20, 2023, with a total volumetric flow rate of 4.5 m³/s, an average total carbon (Total-C) value of 20.74 mg/m³ was achieved, well below the legal limit of 50 mg/m³. Additionally, an average formaldehyde value of 1.41 mg/m³ was recorded, also meeting the legal requirement of 10 mg/m³.
