The M50 Joint Service General Purpose Mask is the United States armed forces Field Protective mask, which began service in December 2009,[1][2] replacing the M40 Field Protective Mask.[3]


The M50 is compact, light, comfortable and more effective as determined by the Defense Department Joint Program Executive Office for Chemical and Biological Defense. The M50 allows for a wide field of view with a single lens that spans the width of the face.[4] The M50 has twin conformal filters, which decreases breathing resistance by 50 percent. This protective mask provides 24 hours continuous eye-respiratory protection in nuclear, biological and chemical (NBC) environments. Another feature is an indicator which turns blue when the filter is expired. [5]
