*The respiratory protection rating is one of the highest. It uses two interchangeable ULPA filters that provide a 99.9995% level of protection against gases, aerosols, dust, bacteria, and viruses. This is a multipurpose type of filter that has an additional filling of treated activated carbon. The filters are IP67 or better protected against moisture. | *The respiratory protection rating is one of the highest.

*The total area of the two filters is oversized so that the breathing resistance is as low as possible, lower than that of counterparts commercially available from leading manufacturers 3M, MCA, Dräger, etc. It is our intention that the wearer will be able to breathe without difficulty even during intense physical exertion. | *The total area of the two filters is oversized so that the breathing resistance is as low as possible, lower than that of counterparts commercially available from leading manufacturers 3M, MCA, Dräger, etc. It is our intention that the wearer will be able to breathe without difficulty even during intense physical exertion. | ||
*To protect the respiratory system from carbon monoxide, a special modification of the removable filters will be developed. | *CPAP (continuous positive airway pressure) and DPAP (dynamic positive airway pressure) make breathing easier during stress and heavy exertion as well as elements of non-invasive pulmonary resuscitation. | ||

*In addition, an adapter will be used to attach a compressed air reducer for SCBA (Self Contained Breathing Apparatus) systems instead of the cover of one of the filters. The second cover, when using the SCBA, blocks the access of contaminated air. | *In addition, an adapter will be used to attach a compressed air reducer for SCBA (Self Contained Breathing Apparatus) systems instead of the cover of one of the filters.

*The mask protects the face in the area of the eyes, ears, forehead, and back of the head from shards of glass, wood chips, stones, and sandy debris, which can have high kinetic energy and cause superficial and penetrating wounds to the face and head. Together with the lower part of the respiratory protection module, the face is fully protected. We have reinforced the outer layer of the mask with a 2.8 mm thick aramid fiber (kevlar) composite layer. This significantly reduces the kinetic energy of fragments in flight and at the same time increases the weight of the product insignificantly. The front and side parts of the head are additionally protected. The back of the head is quite well protected by a ballistic helmet. | *The mask protects the face in the area of the eyes, ears, forehead, and back of the head from shards of glass, wood chips, stones, and sandy debris, which can have high kinetic energy and cause superficial and penetrating wounds to the face and head.
