Which feature of the respirator facepiece is designed to minimize lens fogging?

Explanation:
The feature that minimizes lens fogging is the nose cup. It sits around the nose and creates a seal that helps keep exhaled breath from rising toward the lens. By directing the warm, moist air away from the facepiece’s lens, the nose cup reduces condensation and keeps the lens clearer during use. Straps and chin seals are important for a secure fit but don’t specifically address fogging. A face shield is external protection and doesn’t influence the respirator lens fogging.
