Gas mask is a kind of filtering respiratory protection equipment. It utilizes the mask to form a close contact with the person's face around, and purifies the outside toxic air through the adsorption, absorption and catalytic effect of the adsorbent in the canister and the filtering effect of the filter layer. Provide clean air for personnel breathing.

Gas masks are generally composed of masks, canisters, air tubes, gas masks and so on. Gas masks are roughly divided into direct gas masks and conduit gas masks. Airway gas masks are composed of a mask, a large and medium-sized canister and an airway. Direct gas masks consist of a mask and a small canister. Direct gas masks are small, lightweight and easy to carry. Airway gas masks are slightly larger and heavier and provide longer protection.

In addition, people working in toxic and hazardous gas environments also use gas masks for protection; however, the structure of general-purpose civilian gas masks is not as complex as that of military gas masks, and the specifications are not as stringent as those of military gas masks. For civil chemical protection, more appearance is designed to meet the needs of different people.

1. Filtering gas mask: It consists of mask and canister (or cartridge). The mask includes components such as the body, eye windows, intercom, breathing valve and helmet. The canister is used to purify toxic air and contains a fume filter layer and an adsorbent. These two materials can also be mixed to make filter plates and assembled into cartridges. Lighter (about 200 grams) canisters or cartridges can be attached directly to the mask, and heavier canisters are attached to the mask through an airway.

   2. Isolation Gas Masks: Oxygen is supplied by the mask itself and there are three types: gas storage, oxygen storage and chemical oxygen. Isolation masks are mainly used for high concentration of toxic air (when the volume concentration is greater than 1%), or special occasions such as high altitude, underwater or oxygen-deficient closed chambers.
