A lot of filter on a very small surface

Dinair compact filters are available in all classes from G4-H13. By using a so-called pleat technique, the filtration media’s surface area is greatly increased and attains a compact exterior format. Compact filters are often a better solution than filter pockets in spaces where the area is constricted, the airflow is turbulent or the demands for air purification are extremely high. Note that Dinair compact filters can be manufactured in rectangular and round shapes to ensure the available space is utilized to the full.
