still air
No breeze present
Still air is air that isn't moving—no wind, no breeze, no circulation.
The phrase appears in contexts where airflow matters: The candle flame burned steady in the still air.
In technical contexts, still air describes testing conditions without forced ventilation, as in thermal ratings for electrical components or insulation values.
