The gas mask is an air-purifying respirator for protecting humans from toxic industrial chemicals, biological, nuclear and radiological threats, and chemical warfare agents. The protection offered by this type of mask depends on the size, shape and composition of the particles in the aerosol being filtered, as well as the type of filter used, and the quality of the facial seal.

This army mask is a high-performance full face mask made of bromobutyl rubber to provide exceptional protection against CWA, TIC, BW, and nuclear and radiological agents. It features three NATO 40mm DIN 3283 filter ports and a transparent polycarbonate visor. The NBC-rated mask has been manufactured under strict ISO 9002 quality standards to ensure its durability and reliability. It is easy to fit and comfortable to wear with a breathable mesh head harness and two points of adjustment for fast donning/doffing. It is compatible with a wide range of AirBoss RD DIN 40 filter types, including the X-plore family.
The protective efficiency of a mask is determined by its filtration ability, the degree of fit, and the resistance of respiratory muscles when wearing the mask. To achieve the highest level of protection, a gas mask must be worn properly. Improving the degree of fitting and filtration efficiency, and making masks suitable for different faces will be future development trends. best gas masks
