摘要

Respiratory protection mask for air particles, in particular microorganisms, characterized in that a respiratory protection mask housing (1) rests positively on the face, that an air outlet contains a flutter valve housing (2) with an internal, movable disc (3) which closes the air outlet when inhaling and when exhaling opens, and is preferably integrated into the respirator mask housing (1) pointing downwards, so that an expandable connecting element (4) allows the respiratory mask to rest positively around the nose area and the chin area of the living being and this expandable connecting element (4) is attached to the head area and neck area that a filter housing connection element (5) is firmly integrated in the respirator housing (1) and a filter element housing (6) accommodates that the filter element housing (6) consists of at least two main parts, the filter element housing component below (7) and the filter element Housing component above (9) and at least one filter housing seal Elements (11) consists that the filter element housing component below (7) contains an inner air guide wall below (8), which is designed with an overall height of at least 15mm to 120 mm, and this component is designed to be individually removable from the overall system Filter element housing component above (9) contains an inner air guide wall above (10), which is designed with an overall height of at least 15mm to 120 mm, and is firmly integrated into the filter housing connecting element (5), that after assembly of the filter element Housing component below (7) in the filter element housing component above (9) a filter element housing (6) is formed that thereby a breathing air inlet (12), at least 3 contiguous air flow chambers (13), and a filter air outlet (14) for the respiratory protection mask can be formed, and that because the 3 airflow chambers must each be traversed in their longitudinal direction, a total central length of all airflow channels together of at least 45 mm to 360 mm is created, which the breathing air has to pass through and that, depending on the design, a much longer period of time for more effective cleaning of the breathing air from particles and also the adhesion of microorganisms to the inner walls of the airflow chambers (13) for the microorganisms is available, and that the filter element housing component below (7) can be removed and cleaned.
