  • Filter PAF
  • Insulating lenses for SHM-41mu
  • Anti fog inserts(there are two diameters since kit can be completed with three different masks) 59mm diameter for SHM-41mu and MM-1/ 44mm diameter for SHMS.
  • Spare membranes  type MM-1 and Type SHMS(membranes made for these two masks are same in size but soviets still designated them differently)

Type A bagEdit

Inside of the bag you have two main compartments, for the mask, the filter compartment which features two wooden sticks on the bottom to keep a good airflow for the filter and a special string to pull so it tightens up the compartment of the filter so it doesn't jump around. It also has compartment for the hose and a small inner pocket for antifog inserts/membranes.

Filter EO-16/PAFEdit

Filter designated EO-16 is a big dimensions filter that is obviously used with hoses, it has a 40mm port on the bottom to attach PAF filter which is for added particle protection.dimensions of the EO-16 17.5 × 10.7 cm. The filter of course features typical bumps/rings for protection against physical damage. The rubber plug like on most of other Soviet big dimension filters have small rope attached to the plug so it wont get lost.
