Masks and gas filters are used to protect the body from harmful chemical and biological influences. Many chemicals such as chlorine, hydrogen cyanide, phosgene, mustard agents and others were used during World War I. This caused casualties among allied forces and created the need for protective masks.
Since then gas masks have evolved and protected from all known chemical and biological types. Gas masks use different techniques to protect users. But common components such as the face, hood, eyepieces and filters are in almost all masks.
The most basic mask uses filtering techniques. Pollutants in general have particles larger than oxygen and by using fine mesh this can be prevented. The only drawback is that air supply is also limited in this process. Other processes use quality absorbing certain chemicals such as activated charcoal to control harmful agents. Such masks have limited use, because they can only absorb a few chemicals. The mask is currently using a chemical neutralization method. This Gas Mask Military contains a chemical filter that neutralizes harmful chemicals in the air. Some of them also have tubes for drinking water, communication systems, and winter equipment to prevent fog during cold weather conditions.
This mask provides adequate protection only for the face and internal organs.
