A breathing protector may include an inlet and an outlet, wherein an air flow may be configured to pass from the inlet to the outlet into a trachea. A filter housing may include an inner housing part, an outer housing part, and a filter body. The inner housing party may include the outlet, a tracheal tube fitting and a support structure extending longitudinally and distally from the tracheal tube fitting. A base plate may be arranged in a proximal zone of the tracheal tube fitting and extend radially outwards from the tracheal tube fitting. The outer housing part may include the inlet and form a cage enclosing the support structure. The filter body may be arranged between the support structure and the outer housing part. |
