Activated Carbon for
Air & Water Filtration
Gremarco provides high-performance activated carbon filter media for air purification, water filtration, odor control, and specialty filtration applications. Our media delivers effective adsorption of VOCs, chlorine, organic compounds, and unwanted odors from both air streams and water systems.
Available in rolls, sheets, and custom-cut formats, with flexible substrate options, custom carbon loading levels, and precision converting capabilities, Gremarco media supports a wide range of industrial, commercial, and engineered filtration solutions.
How Activated Carbon Filtration Works
1
Adsorption
Unlike absorption, where a substance is taken up by another substance, adsorption involves molecules of a gas or liquid adhering to the surface of a solid material (in this case, activated carbon).
2
Contaminant Removal
As air or water passes through the activated carbon filter, various contaminants are attracted to the carbon surface and become trapped within its pores. This includes chemicals, odors, smoke, VOCs, and some heavy metals.
3
Clean Output
The air or water that exits the activated carbon filter is typically much cleaner, as many of the unwanted particles and odors have been removed or reduced significantly.
Applications of Activated Carbon
Residential Air Purifiers
Used to improve indoor air quality in homes by removing everyday odors such as cooking, pet, laundry and garbage odors as well as smoke and other airborne VOCs. Found in room air purifiers, dehumidifiers, range hoods, and residential HVAC filters.

Commercial and Industrial Settings
Commonly used in HVAC systems in schools, hospitals, and manufacturing facilities, where gas-phase filtration adsorbs fumes, chemical contaminants, and odors. Also a critical component in gas masks and respirators, protecting wearers from harmful gases and chemicals.

Water Treatment
Used to adsorb chlorine and disinfection byproducts such as trihalomethanes, along with pesticides, VOCs, and other dissolved organic compounds. Most widely used method for improving the taste, odor, and overall quality of drinking water and purifying water for aquariums and ponds.
It's important to note that while activated carbon is highly effective at adsorbing many types of contaminants, it may not be as effective for particulate matter (e.g., dust, pollen, bacteria). Therefore, in some air purification systems, activated carbon filters are used in combination with HEPA (High Efficiency Particulate Air) filters to provide comprehensive air purification.
