breathable air
What lungs need
Air suitable for human respiration—containing adequate oxygen and free of dangerous concentrations of pollutants, toxins, or smoke.
The phrase appears most often in environmental and safety contexts: The fire filled the building with smoke, leaving no breathable air.
In space exploration, breathable air is a critical life-support requirement.
