MSA and 3M sites shown. I always carry an MSA full face air purifying respirator with GMCH (dual HEPA\Organics) cartridges. If your cartridges have been open or you even have the slightest doubt, replace them.

REMEMBER-----> No air purifying respirator is recommended for any type of Immediately Dangerous to Life and Health (IDLH) atmosphere.
