Filter mask
From Freepedia
A filter mask or particulate mask is a protective mask which usually covers the mouth and nose only. It compels its wearer to breathe in through a filter which removes harmful dust or toxic gases from the air. The filter cartridges are filled with activated carbon or certain resins that will absorb substances such as volatile organic compounds (VOCs), eliminating them from the breathing air. There are different cartridges for different compounds. Filter cartridges can become saturated, then they must be changed.
