The filter is cleaned in a liquid concentration with a biodegradable medium at a temperature of about 50 degrees Celsius. During regeneration a cavitation process takes place, which guarantees restoration of parameters close to the factory parameters of the new filter.

Unlike burning the filter out in an induction furnace or pouring chemical on the DPF only the hydrodynamic method guarantees a clean filter. An induction furnace damages the monolith of the DPF filter by using very high temperature. The filter ceramics are also not resistant to direct effects of chemistry, e.g. dimmer.
