I ask this because every pool or water park I went too always made me take my mask off. I need it because my sinuses and eyes are sensitive to chlorine and regular nose plugs and googles that only cover the eyes don’t work for me. I love diving and just being under water without the worry of chlorine water burning my sinus and eyes. For that reason I no longer go to water parks or public pools I only swim in the pool my sister in law owns. I just don’t understand this rule sorry.
