What is Activated Carbon Filter ?
An activated carbon filter is a filtration device that uses porous carbon to adsorb gaseous pollutants such as formaldehyde, benzene, and hydrogen sulfide, as well as odor molecules in the air. It improves air quality and is commonly used in medium- and low-temperature environments.
Test Methods or Activated Carbon Filters
1. Adsorption Efficiency Test
Method: Fill the test chamber with the target pollutant, then measure the concentration difference between the filter’s inlet and outlet to calculate adsorption efficiency.
Purpose: Determines the filter’s ability to remove specific particles or gaseous pollutants.
2. Airflow Resistance Test
Method: Measure the initial pressure drop (Pa) at the rated airflow rate.
Purpose: Evaluates ventilation performance to ensure low energy consumption and high airflow efficiency.
Key Technologies of ClearFilter Activated Carbon Filters
Composite Modification of Filter Material
ClearFilter optimizes activated carbon’s multi-level pore structure to create a “molecular sieve” effect, enabling highly efficient capture of 0.3–10 μm gaseous molecules.
Precision pore distribution: Regulates micropores (<2 nm), mesopores (2–50 nm), and macropores (>50 nm) for enhanced adsorption efficiency.
Customized purification: Combines material composite technology (polarity enhancement, catalytic decomposition, antibacterial properties) and surface modification (chemical impregnation, hydrophobic treatment) to maximize adsorption capacity and filter lifespan.
Low Wind Resistance & Long-Life Structural Design
Hydrodynamic optimization & high-density filling: ClearFilter balances adsorption performance and system energy efficiency.
Gradient adsorption design: Adjusts pore size distribution along airflow direction, increasing adsorption efficiency by 20–30% and extending filter lifespan.
Application Scenarios of Activated Carbon Filters
Indoor Air Purification
ClearFilter activated carbon filters are used in fresh air systems and air purifiers to efficiently remove:
- Renovation pollutants: Formaldehyde, benzene, and VOCs.
- Household odors: Kitchen fumes, pet smells, and cigarette smoke.
They create a healthier indoor environment, particularly benefiting sensitive individuals (elderly, children, pregnant women). For example, in a newly renovated home, running an air purifier with ClearFilter can significantly reduce formaldehyde levels, ensuring safe occupancy.
Industrial Exhaust Gas Treatment
Used in industrial air filtration systems, ClearFilter activated carbon filters help purify exhaust gases in chemical, electronics, and pharmaceutical production, preventing pollutants from entering the atmosphere and maintaining a clean production environment.
Industrial Applications:
1.Cleanroom Ventilation Systems
Cleanroom Ventilation Systems remove VOCs, acid gases (HF, HCl), and ammonia (NH₃) to maintain air purity. In lithography, they adsorb solvent gases from photoresists like PGMEA, while in etching and cleaning, they filter gases such as Cl₂ and HBr generated during the process.
2.Process Exhaust Systems
Process Exhaust Systems capture high-concentration toxic gases directly from production equipment to prevent environmental contamination. In CVD (Chemical Vapor Deposition), they adsorb unreacted silane (SiH₄), phosphine (PH₃), and other hazardous gases, while in ion implantation, they filter dopant gases like BF₃ and AsH₃.
3.Localized Equipment Exhaust
Localized Equipment Exhaust purifies emissions from specific equipment, ensuring a safer working environment. In photolithography machines, they adsorb benzene released during photoresist baking, while in wet cleaning equipment, they capture ammonia vapors from SC1/SC2 cleaning solutions (NH₄OH + H₂O₂).
Real Customer Case : Cleanroom in an Electronics Manufacturing Factory
Challenge: The soldering process generates high levels of organic waste gases.

- Toluene concentration reduced from 2.5 ppm to 0.1 ppm.
- Filter replacement cycle extended to 6 months.
- Workshop air quality met OSHA standards after audit.
Activated Carbon Filter FAQs
It is recommended to replace the activated carbon filter in 6-12 months under normal environment, depending on the concentration of pollutants and the length of use to monitor the saturation status.
It is not recommended to wash the activated carbon filter, as it will cause the microporous structure to collapse, Clear Filter provides professional thermal desorption regeneration service.
With optimized encapsulation process, the amount of carbon dust released is less than 0.01mg/m³, which meets the cleanliness requirement of ISO 5.
Choose the airflow according to the room area (㎡): airflow (m³/h) = area x floor height x number of air exchanges (5 times/hour recommended).
