Which component prevents the face piece from fogging up?

Explanation:
Fogging happens when warm, moist breath condenses on the cooler inner surface of the lens. The nose cup inside the facepiece channels exhaled air away from the lens, directing it downward and keeping the lens surface warmer and drier. This targeted airflow prevents condensation from forming on the visor, making it the component that most directly reduces fogging. The head harness and straps simply secure the mask, while the lens is the surface that would fog if breath isn’t redirected.
