It removes harmful chemicals from the air you are breathing.
When you have a viable and properly designed AND properly used gas mask you can avoid the damage of nerve gas.
A gas mask is a protective device worn over the face to filter out harmful gases, vapors, and particulates from the air. It typically consists of a mask that covers the eyes, nose, and mouth, along with a filter cartridge that cleans the incoming air. Gas masks are used in various situations, including military operations, industrial environments, and during chemical emergencies. They are designed to provide respiratory protection and help the wearer breathe safely in contaminated environments.
The lifespan of a gas mask filter varies depending on factors such as the type of contaminants, the environment, and the filter's design. Generally, a filter can last anywhere from a few hours to several days under normal conditions. It's crucial to check the manufacturer's specifications and replace the filter when it becomes saturated or after a specific usage timeframe, as indicated. Regular inspection and maintenance are essential for effective protection.
No, It was made post ww2 where they stopped using asbestos in the filters. 100% safe.
A gas mask is a mask worn over the face to protect the wearer from inhaling airborne pollutants and toxic materials. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Some gas masks are also respirators, though the word gas mask is often used to refer to military equipment (e.g. Field Protective Mask, etc.) (The user of the gas mask is not protected by gas that the skin can absorb.)

Peach pits were used during World War I as filter for their gas masks. They would soack them in urine and make a special charcoal out of them that was used for the mask.
So long as you purchase a filter designed specifically for the PMK, since these were made somewhere between the late 80's and early 90's, no, they do not contain asbestos. However, gas mask filters have life spans of only a few hours once they are used for the first time. They can be stored for some years, but as soon as a breath is taken through them, the clock begins ticking. In most cases the average filter life is roughly 40 total use hours before the contents of the filter become saturated and unable to remove harmful gases from the air. The safest thing to do is never breath through a gas mask filter unless you have to. Never breath through one for long periods of time, and NEVER use a filter or mask purchased at a surplus store or on-line to attempt to protect against actual threats (biological / chemical agents). 99.9% of masks found in surplus stores have either been used in military exercises, or have defects which lead them to your hands. Never trust a mask that was not specifically fitted for you in person. Even 1mm of space between your face and the mask can allow harmful agents to infiltrate and turn your mask into a gas chamber.
