The best escape type respirator on the market right now seems to be the AVON EH20, probably the best deal in a military style mask is the MCU-2/P although as the M50 JSGPM becomes more widely fielded I would expect to see many more M40 series masks on the market for reasonable ammounts. You need to be clean shaven, and trained in how to properly don it as well as understand how it will impact you.
The mask should fit you well and be in good repair as well as be in a configuration that meets your requirements. As a result you have to take a hard look at the threat environment that you live or work in and decide if is necessary for you.Īt the most basic level the cartirdge is the most critical component, namely it needs to be well sealed and not exposed to the ambient air. That said, like all things, if you ever intend to purchase an Air Purifying Respirator rated for CBRN threats it will only protect you if you carry it with you, as you know. These chemicals will likely present a hazard primarily when inhaled and these masks can do a very effective job of managing the consequences of these agents allowing you to remove yourself from the environment. While a wide area, high purity, chemical warfare attack by a state actor on our soil is a low likelyhood event, the possibility of accidental or intentional release of toxic industrial chemicals is much higher. Wiggity, it is a very valid question despite some of the responses.
