The Activated Carbon Air Filter Cartridge 102×65 is a high‑performance cylindrical filtration element engineered for the removal of gaseous pollutants, odors, and volatile organic compounds from air streams. This compact air filter cartridge is manufactured to your exact specifications for seamless integration into air purifiers, HVAC systems, industrial exhaust units, and process air handling equipment where chemical filtration is required.
Unlike standard particulate filters that capture solid particles, an activated carbon filter cartridge operates through adsorption—a process where molecules of gases, odors, and VOCs adhere to the vast porous surface of the activated carbon media. Activated carbon possesses a highly porous internal structure, creating an enormous specific surface area—each gram of activated carbon can contain hundreds to thousands of square meters of adsorption surface. When contaminated air passes through the element, pollutant molecules are physically trapped within these micropores, effectively removing them from the airstream.

This is a kind of custom air filter. If you want to customized the filters, please send details to us to get the price.
Choose the Custom Paper Filter when you need the lowest upfront cost for a perfect fit in a dry environment with a defined maintenance schedule. It’s a simple “remove and replace” solution.
Choose a Washable Polyester Filter if you operate in a high-dust, moist, or demanding environment where the long-term savings of reusability outweigh the higher initial cost and need for cleaning.
Choose an activated carbon filter when your air contains:
Unpleasant odors (cooking, pets, bathrooms, smoke)
Volatile organic compounds (VOCs) from paints, adhesives, cleaning products, new furniture
Formaldehyde (from pressed wood products, building materials)
Chemical fumes (solvents, ammonia, hydrogen sulfide)
Exhaust gases (ozone, nitrogen dioxide, sulfur dioxide)

Choosing Huahang Filter’s air filter cartridge means investing in reliability, cost savings, and peak baler performance.
Q: What is the difference between a particulate filter and an activated carbon filter?
A: A particulate filter (HEPA, bag filter) captures solid particles like dust, pollen, and mold spores. An activated carbon filter adsorbs gaseous pollutants—odors, VOCs, formaldehyde, smoke, and chemical vapors—that pass right through particulate media.
Q: How does activated carbon adsorption work?
A: Activated carbon is processed to create millions of microscopic pores, giving it an enormous surface area. When contaminated air passes through the filter, pollutant molecules are physically trapped within these pores through a process called adsorption. Unlike absorption (where the pollutant is absorbed into the material), adsorption holds the molecules to the surface without chemical change to the carbon.
Q: Can this carbon filter be cleaned and reused?
A: No. Unlike particulate filters, activated carbon cannot be effectively cleaned. Once the micropores are saturated with adsorbed pollutants, the carbon has reached its adsorption capacity and must be replaced.
