Desorbable adsorption filter and method for controlling the process of desorption of such a filter

The filter element (12) can be heated for desorption in a desorption mode. At least one contactless operating first temperature sensor (14) mounted in or on the housing (10) in desorption mode detects the temperature of at least a first section (18) of the filter element. Independent claim describes method for controlling desorption process of filter by contactless detecting the temperature of a first section of the filter element and then regulating the temperature of the filter element by adjusting the heating power which heats the filter element.
