Volatile Organic Compounds (VOCs) are organic chemicals that vaporize easily at ambient temperatures. Prevalent in both indoor and outdoor air, they present considerable hazards to human health. As a highly porous material with extensive specific surface area, activated carbon is widely applied to adsorb and eliminate VOCs from airflow.

Multiple key factors determine the VOC removal performance of activated carbon:

• VOC Concentration: Higher VOC levels normally accelerate the adsorption process.
• Molecular Weight: Larger VOC molecules are adsorbed more effectively than smaller ones.
• Surface Area: Activated carbon with a larger specific surface area delivers higher adsorption capacity.
• Pore Size Distribution: The pore structure must match the molecular size of target VOCs.
• Temperature & Humidity: Lower temperature and relative humidity help boost adsorption efficiency.
• Airflow Rate: Reduced airflow extends contact time between VOCs and carbon media, optimizing adsorption results.
