1. A breathing protector, comprising: an inlet and an outlet, wherein an air flow is configured to pass from the inlet to the outlet into a trachea, a filter housing including an inner housing part, an outer housing part, and a filter body;wherein the inner housing part includes the outlet, a tracheal tube fitting and a support structure extending longitudinally and distally from the tracheal tube fitting toward a distal portion of the outer housing part, a base plate arranged in a proximal zone of the tracheal tube fitting and extending radially outwards from the tracheal tube fitting;wherein the outer housing part includes the inlet and forms a cage enclosing the support structure; andwherein the filter body is pressed by the support structure against the outer housing part, thereby conforming the filter body between the support structure and the outer housing part, further comprising a heat moisture exchanger arranged between the support structure and the outer housing part. 2. The breathing protector according to claim 1, wherein the inner housing part includes a pinch plate arranged distally of the base plate. 3. The breathing protector according to claim 2, wherein the pinch plate extends radially outwards from the tracheal tube fitting, wherein the filter body is pinched between the pinch plate and the outer housing part. 4. The breathing protector according to claim 2, wherein the base plate extends laterally beyond the pinch plate, and the outer housing part extends distally from the base plate. 5. The breathing protector according to claim 1, wherein the heat moisture exchanger is arranged between the support structure and the filter body. 6. The breathing protector according to claim 1, wherein the heat moisture exchanger is arranged distally of a pinch plate such that the heat moisture exchanger is not pinched to the filter body. 7. The breathing protector according to claim 1, wherein the heat moisture exchanger defines a through hole. 8. The breathing protector according to claim 1, wherein the tracheal tube fitting is a cylindrical body. 9. The breathing protector according to claim 8, wherein the cylindrical body has a central axis A and extends longitudinally in the proximodistal direction, and the cylindrical body has a slightly decreasing cross sectional area in the transversal plane when moving distally along the central axis A. 10. The breathing protector according to claim 1, wherein the support structure includes at least one of support fingers, support bars, and support ribs, each defining slots there between. 11. The breathing protector according to claim 1, wherein the inner housing part and the outer housing part are connected along a contact plane at a proximal end of the outer housing part. 12. The breathing protector according to claim 11, wherein the inner housing part and the outer housing part are connectable along a periphery of the base plate. 13. The breathing protector according to claim 11, wherein the outer housing part includes a gripping element distributed circumferentially of the proximal end of the outer housing part configured to grip a periphery of the inner housing part for bringing the outer housing part and inner housing part into connected cooperation. 14. The breathing protector according to claim 13, wherein the gripping element is a gripping flange extending circumferentially of the outer housing part. 15. The breathing protector according claim 1, wherein the inner housing part is welded to the outer housing part. 16. The breathing protector according to claim 1, wherein the outer housing part is at least one of perforated and provided with ribs, such perforation or ribs extending distally to a top of the outer housing part to a connection point. 17. The breathing protector according to claim 9, wherein the filter body is arranged in at least one of a corrugated and pleated form in at least a part between the inner housing part and the outer housing part. 18. The breathing protector according to claim 17, wherein a distal top part of the filter body is substantially flat, extending transversally to the central axis A of the breathing protector. 19. The breathing protector according to claim 5, wherein the heat moisture exchanger is arranged in at least one of a corrugated and pleated form in at least a part between the inner housing part and the outer housing part. 20. The breathing protector according to claim 2, wherein a groove is arranged between the base plate and the pinch plate on the inner housing part. 21. The breathing protector according to claim 1, wherein an outer surface of the support structure is complementary to the inner surface of the cage such that the filter body is conformed to the inner surface continuously. 22. The breathing protector according to claim 1, wherein the cage is dome shaped. 23. The breathing protector according to claim 1, wherein the cage bulges distally away from a contact plane with the base plate of the inner housing part such that an inner surface of the cage has a greater surface area than a cross sectional area of the base plate; andwherein the support structure is shaped to conform the filter body to the inner surface of the cage.
