activated carbon
The current materials used in gas mask filters provide effective protection against all of these compounds, despite the very different chemical properties of the gases. Gas mask filters include activated carbon, a family of absorbents that trap toxins in millions of micro-pores.
How does a gasmask filter work?
Through adsorption, a solid or a liquid can trap particles on its surface—analogous to the way a cigarette filter reduces the amount of toxins a person inhales when smoking. To filter out harmful chemicals, most gas mask filters are made with activated charcoal, or oxidized charcoal.

What are the three types of respirators?
The three basic types are: Half Mask/Dust Mask, Half Mask (Elastomeric), and Full Facepiece (Elastomeric). 2. Non-Powered Air-Purifying Respirators: When using a non-powered air-purifying respirator, the user operates it simply by breathing.

The inhale valves that are placed into the sides of the mask onto the filter.
What are the advances in gas mask technology?

How are gas masks used in the French military?
US Navy MCU-2/P gas mask system. Gas mask used by the French military. The filter cartridge is connected via a flexible hose.
