The inhalation tube and the expiratory tube are separated, the inhaled is all oxygen, and the exhaled carbon dioxide will flow out from the exhalation tubes on both sides, ensuring that you have enough oxygen during snorkeling without causing injury and suffocation due to lack of oxygen , so as to truly achieve safe snorkeling.
The increase in the exhalation passage ensures that the exhaled gas is quickly expelled, preventing the mask from fogging because the exhaled gas cannot be effectively discharged. A separate exhaust passage does not cause re-intake of exhaust gases (carbon dioxide), ensuring that you are inhaled with oxygen rather than a mixture of oxygen and carbon dioxide during snorkeling.
