ABSTRACT:
Respirator 10 has a respirator body 11 that is configured to fit over the nose and mouth of a wearer. A thermochromic material 18 is positioned on the respirator body 11 such that the thermochromic material 18 makes thermal contact with the wearer's face when the respirator 10 is worn. The contact causes the thermochromic material 18 to change color to allow the wearer to determine if a proper fit has been established.
