Question

What is used in gas mask to absorb poisonous gases?

Answer 1

Answer:

Charcoal absorbs and holds a fairly large volume of poisonous gases in a gas mask.

Explanation:

To filter out harmful chemicals, most gas mask filters are made with activated charcoal, or oxidized charcoal. When charcoal is activated with oxygen, it becomes ripped with tons of "sticky" holes in each molecular structure just like chicken wire. Any toxins that pass through the charcoal become bonded to these holes, and are prevented from moving into the gas mask.
