Activated Carbon

Gremarco utilizes a coconut shell activated carbon, also known as activated charcoal, that has been specially treated to have a highly porous structure. This porous structure provides a large surface area, which is essential for adsorption.

Activated carbon is a widely used technology for removing a variety of pollutants and impurities from the air and water. It is particularly effective at adsorbing and neutralizing gases, volatile organic compounds (VOCs), odors, chlorine & chloramines, heavy metals such as mercury and lead and certain other chemical contaminants.

Here's how activated carbon filtration works:



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).


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.


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:

These are often used to improve indoor air quality by removing odors, smoke, and VOCs.


Commercial and Industrial Settings:

Activated carbon filters are used in HVAC systems, manufacturing processes, and other applications to remove fumes, chemical contaminants, and odors.


Water Treatment:

Activated carbon is also used in water treatment systems to remove organic contaminants, chlorine, heavy metals and other impurities from water.


Gas Masks and Respirators:

Activated carbon filters are a critical component in gas masks and respirators, where they help protect the wearer from harmful gases and chemicals.

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.
