In order to be able to deliver a convincing cleaning quality, we have had our cleaning process checked and certified by TÜV Rheinland.

Several new, cleaned and dirty filters were compared in this series of tests. TüV Rheinland found out that our cleaning process restores the flow characteristics of cleaned filters to a comparable quality of new filters. This means that filters cleaned by us can be equated with new filters.
