Researchers found that current gas mask filters can be used to counter current threats. However, there is a lot of uncertainty about their molecular mechanisms. This question arises because many of the filters are designed to deal with a wide variety of chemical threats that change constantly and can be used in a variety of conditions around the globe.
Currently, you can find a wide range of protective gas masks on https://www.gasmaskpro.com/ that are designed to serve various purposes and vary in their functioning. Chemical warfare agents were primarily chlorine and mustard gas during World War I. A new type of chemical weapon has emerged since then. Nerve agents such as sarin and venomous agency X (or VX) are named for their ability to interfere with nerve system communication with muscles.
Gas mask filters currently use materials that provide effective protection against all these compounds, despite their very different chemical properties. Activated carbon is a group of absorbents that trap toxic substances in millions of tiny pores.
This compound is also used to filter water and prevent poisoning from being ingested. To help eliminate toxins, activated carbon traps them. However, in gas masks, it's further enhanced with metal oxides such as molybdenum and copper to aid in their breakdown.
