Filter (TL 7): Filters are breathing masks that strip out harmful elements from the air inhaled by the character, such as dangerous gases or dust particles. The TL 10 filter is small enough to fit into the nose, or can even be a lung implant.
Respirator (TL 6): This device concentrates inhaled oxygen, allowing a character to breathe on worlds with a thin atmosphere. Respirators take the form of a face mask or mouthpiece initially.
The more advanced TL 10 respirator is small enough to fit into the nose, or can even be a lung implant.
