Air is drawn into the structure through inlet valve 1. It passes through ventilator filters 2. Combined with a transition 3, it enters the mask. In the mask, in the eye compartment 4, the glass cools and enters the sub-mask compartment (separating the eyes from the nose) (it may be worth removing for easier breathing). It enters the nasal and oral compartment 5. It is inhaled by the body. When exhaling, upper valves 1 prevent air from returning through the same path and air flows downward. It passes into the lower section through an opening where the water drain valve was, entering adapter 6. It passes through the exhalation valve 7. Through ventilator filter 8, it is expelled from the structure. Standard airflow channels for swimming 9 are blocked by any available means (e.g. sealed with epoxy). For additional protection, the exhalation valve 7 should be made double. In case air filtration of the exhale is not needed, ventilator filter 8 is not installed. The exhalation valve 7 is placed before the exhale filter 8 to facilitate replacement of the exhale filter while in a dirty area.
