Activated charcoal is derived from carbonaceous materials such as coal, coconut shells, wood, or other substances. The production process involves subjecting charcoal to high temperatures in the presence of a gas or activating agent, which expands its surface area, resulting in the formation of “activated charcoal.”
This versatile substance is widely used in various industries due to its superior adsorption properties.

How Activated Charcoal Works: The Science Behind Adsorption
The activation process creates a network of microscopic openings of various sizes on the surface of charcoal. These openings increase the internal surface area, making it accessible for water and other substances. Activated carbon has a natural affinity for organic pollutants, which bind to its surface through a process called adsorption.
During activation, the carbon forms tiny pores and pockets, expanding its surface area significantly. At the pore walls of activated carbon, an imbalance of forces exists. To neutralize this imbalance, particles are physically adsorbed onto the pore walls through Van der Waals forces.
In simpler terms, compounds such as pesticides, chloroform, and toxins enter the openings of this honeycomb-like structure and are held firmly through adsorption. The porosity of activated carbon provides an extensive surface area for adsorption to take place.
Importantly, adsorption occurs in pores slightly larger than the molecules being adsorbed. Therefore, matching the particle size of the target substance to the pore size of the activated charcoal is crucial for optimal performance.
Activated Charcoal Products
Our products are sourced from natural products such as coconut shell, coal, wood and so forth.
Coconut Shell Activated Charcoal
Coconut shell activated Charcoal, made from coconut husk, is a vapor-activated material
Coal Activated Charcoal
Coal based activated Charcoal originates from coal that has undergone a steam activation process
Water Washed Activated Charcoal
Water washing is primarily performed to remove ash content from the granular activated Charcoal.
Acid Washed Activated Charcoal
Our acid wash products are NSF certified and are available in various mesh sizes
Wood Charcoal
Wood activated Charcoal is formed when carbon-containing raw wood is carbonized in a limited supply of air
