What term describes the system that moves air into and out of a workspace to maintain air quality?

• A. Ventilation
• B. Filtration
• C. Humidity Control
• D. Insulation

Answer: (A)

Ventilation describes the process of moving air into and out of a space to dilute contaminants and keep the air quality at safe levels. In a backstage environment, this means bringing in fresh outdoor air and exhausting stale air, which helps remove odors, fumes, and heat buildup. Filtration is a related function that cleans particles from the air but doesn’t by itself handle the exchange of air volumes. Humidity control focuses on moisture levels, and insulation reduces heat transfer but doesn’t move air. So the term that best fits the description is ventilation.
