You should learn a proper breathing rhythm and not rely on masks or nose clips for the long run. In my opinion their ok to use to learn with or for over coming a fear for the short run. You say you breathe out through your mouth so why not breathe out through your nose too ? Breathing out through your nose even very slightly will not allow water to enter . A properly timed breathing rhythm will also not allow water to enter your nose meaning waiting for your face to clear the water before you inhale .
