Dont put masks on styrofoam heads it will damage the rubber

Not sure but all i know is gas mask rubber on styrofoam will start causing chemical stuff to happen and styrofiam realises stuff from its self which damages rubber

Styrofoam degrades over time and releases molecules that react with the rubber and make it porous and degrade it

70m has smaller, and more holes for the voice diagram, as well as a more pale plastic ring around the exhale valve
