Puragen Activated Carbons offers products used in the automotive industry for evaporative emission control. Special, highly mesoporous activated carbon is used in canisters mounted within the vehicle to adsorb fuel emissions when the vehicle is turned off and to recover fuel when the vehicle is restarted. OxPureâ„¢ activated carbon with very high surface area is used for cabin air filters to adsorb many odors and chemicals in order to maintain a healthy atmosphere within the vehicle.

First used as a purifier in approximately 1500 BC, activated carbon reached the modern world in the 19th century via the sugar refining industry in Europe. Today, it plays a vital role at the home, municipal, and industrial levels, including the automotive industry.

Activated carbon has a tremendous surface area and a vast network of microscopic pores. It attracts an incredible range of both organic and inorganic compounds. It can be used alone or impregnated with specific chemicals to enhance its effectiveness against specific compounds.

In the automotive industry, activated carbon is used to control emissions, remove VOCs (volatile organic compounds), and improve the quality of cabin air. It can also be used to create electrodes for supercapacitors.

Cabin Air Filters

Automotive cabin air filters purify air to reduce odors using either GAC or activated air filter pads that can be replaced as needed. Coconut shell activated carbon's mechanical hardness and high microporosity make it a common choice.

Evaporative Emission Control Canisters

The activated carbon used for automotive evaporative emission control canisters features low density and high mesopore volume. This combination enables consistent adsorption and release of gasoline vapors in the fuel system.


In the ultracapacitor (ELDC) application, activated carbon with specific powder particle sizing, high activity, and high purity increases battery performance capabilities. Puragen Activated Carbons meets and exceeds high ELDC standards.
