What is Activated Bamboo Charcoal?

Activated bamboo charcoal is made by heating the bamboo charcoal until all the non-carbon material is removed. The bamboo is heated in a kiln at a high temperature with limited oxygen access.

Chlorine salts are used to make the charcoal more porous. A dilute acid solution is then used to remove excess charcoal until only the purest fine charcoal powder is left behind.

The charcoal is then granulated and activated by passing steam through its granules to increase its surface to mass ratio. Another method for activating the charcoal is injecting an oxidizing gas such as carbon dioxide through the charcoal granules.

According to research, one gram of activated bamboo charcoal has a surface area of more than six hundred square meters.

How Does it Work?

Bamboo charcoal has millions of tiny micro-pores that act as suction holes that absorb bad odors and toxins in the air as a vacuum would. The absorbed pathogens or odors then stay trapped in the charcoal pores. Once the charcoal pores are full, they stop working and are rendered inactive.

Charcoal attracts particles in the air and absorbs them, which is known as adsorption. Any absorbed pathogens in the charcoal pores eventually die off since there are no nutrients for propagation.
