A breath mask was a device that converted water into oxygen, allowing beings dependent on oxygen to stay underwater for long periods of time. During the Invasion of Utapau, Jedi Master Jard Dooku and Jedi Knight Obi-Wan Kenobi used breath masks while swimming through Utapau's Aquarian Ocean to reach the Gungan city of Otoh Gunga.
