Abstract
The filter element comprises a filter medium which is incorporated into an assembly made of plastic components. At least one of the components incorporates titanium dioxide as a filler. The treatment of such a component with a laser produces a dark pigment within the component and thus can be used to form characters on the component to convey information regarding the filter element such as product part number, lot code, serial number or flow arrow.
