This type of activated carbon undergoes a process where specific chemical reagents (impregnation solution) are added, giving it the ability to catalytically decompose specific toxic gases, rather than simply relying on physical adsorption. Therefore, its efficiency and applicability far exceed those of ordinary activated carbon.

Colin has successfully developed a new type of air purification device using advanced technology: impregnated activated carbon. Tests show that this activated carbon can efficiently adsorb more than ten kinds of toxic and harmful gases, including benzene, sulfides, formaldehyde, and ozone. Its adsorption capacity is 5.8 to 78 times that of similar domestic products, and it can provide more than 540 hours of continuous purification. This fully demonstrates the superior performance of impregnated activated carbon in complex and harsh diving environments.
