Your air underwater can function in many ways. You can clear your mask by exhaling through your nose. You can blow up a balloon to send to the top with a cord or anything else. You can find which way is up if you lost that sense in a tumble or darkness and you can spot other people underwater if they have an open breathing system or mishap.
