👉 Unventilated, also known as "open air" or "closed space," is a state of being without any ventilation. This can refer to either an open air environment (like a forest) or a closed space within an enclosed structure (like a room). In both cases, the atmosphere inside the space is not maintained at a certain level, which allows for poor air quality and potentially harmful health effects such as mold growth, dust accumulation, and respiratory issues.
