How long will the POTOMAC® Emergency Escape Mask provide protection for? For every mask, the protection time will differ depending upon many variables—a few of which are the air temperature, humidity level, type of agent, and concentration level of the agent. It is impossible to give an exact time. The table below lists some of the tests we have conducted at distinguished independent laboratories.
