Understanding Activated Carbon Filters
What Are Activated Carbon Filters?
Activated carbon filters are designed to remove various pollutants from the air. These filters are made from small pieces of carbon that are treated to be extremely porous.
As a result, the carbon has a large surface area, which makes it highly effective at trapping pollutants. This is why activated carbon filters are commonly used in air purifiers and HVAC systems.
Structure and Composition
Activated carbon filters are made up of small bits of carbon. These bits have been processed to be extremely porous.
The pore structure of activated carbon is what makes it an effective filtration system. The surface area of activated carbon is very large. This allows it to adsorb many more contaminants than standard carbon filters.
The carbon used in activated carbon filters is typically derived from coal, wood, or coconut shells. The most commonly used form of activated carbon is activated charcoal.
Activated carbon filters come in two main types: granular activated carbon (GAC) and carbon block filters.
GAC filters consist of small granules of activated carbon packed into a canister or other container. Water or air flows through these containers and comes into contact with the porous surfaces of the GAC granules.
The contaminants in the water or air can then be physically trapped by the small pore sizes of the granules.
Carbon block filters, on the other hand, consist of compressed activated carbon particles that have been formed into a solid block.
💡 To better understand the science behind their operation, take a look at our post “The Science Behind Activated Carbon Air Filters” which explores the activation process and adsorption properties that make carbon such
Activated carbon filters work through a process called physical adsorption. When air or water passes through the activated carbon filter, the contaminants in the air or water are attracted to the surface of the activated carbon through physical adsorption forces.
These forces cause the contaminants to stick to the surface of the activated carbon, effectively removing them from the air or water.
Activated carbon filters are especially effective at removing volatile organic compounds (VOCs) and smoke from the air. They can also help eliminate unpleasant odors so your indoor air remains fresh. Used together, activated carbon and HEPA filters can trap 99.97% of small particles 0.3 microns and higher as well as most larger particles, especially spores.
Activated carbon filters have several advantages over other types of filters. They are relatively inexpensive and easy to install, and they require very little maintenance. They are also very effective at removing a wide range of contaminants from the air or water. However, they are not very effective at removing airborne particles, and they do need to be replaced regularly to maintain their effectiveness.
Benefits of Activated Carbon Filters
Activated carbon filters are a popular type of filter used in both air purifiers and water filters.
These filters have many benefits, making them an excellent choice for anyone looking to improve the quality of their air or water.
In this section, I will discuss the advantages of activated carbon filters in both water and air purification.
Activated carbon filters are highly effective at removing impurities from drinking water.
They can remove sediment, chlorine, and organic compounds that affect the taste and odor of water.
Additionally, activated carbon filters can remove bacteria and other hazardous compounds from water, making it safer to drink.
One of the biggest benefits of activated carbon filters in water treatment is their ability to remove volatile organic compounds (VOCs).
These are organic molecules that can be found in many household products, such as pesticides and petroleum-based products.
VOCs can be harmful to your health, so removing them from your drinking water is essential.
Activated carbon filters are highly effective at removing pollutants from the air. They can remove dust, smoke, and volatile organic compounds (VOCs) from the atmosphere. Activated carbon filters work by adsorbing these pollutants. This means they stick to the surface of the carbon.
This process is highly effective at removing pollutants from the air.

Maintenance and Replacement of Activated Carbon Filters
As with any type of filter, regular maintenance and replacement are necessary to ensure the optimal performance of activated carbon filters.
The lifespan of an activated carbon filter depends on several factors.
These factors include the quality of the incoming water or air, the volume of water or air filtered, and the specific design of the filter.
However, a general rule of thumb is to replace the filter every 6-12 months for home use, or more frequently for commercial or industrial use.
Maintenance Tips for Activated Carbon Filters
To keep your activated carbon filter clean and effective, here are some maintenance tips:
- Clean the pre-filter regularly to prevent larger particles from clogging the activated carbon.
- Check the filter housing for any cracks or leaks that may compromise the filter’s effectiveness.
- Replace the filter if you notice a decrease in water or airflow, or if you notice a decline in the taste, odor reduction, or clarity of water or air.
- Follow the manufacturer’s instructions for cleaning and replacement of the filter.
Replacement of Activated Carbon Filters
Replacing activated carbon filters is a simple process that can be done by following these steps:
- Turn off the water or air supply to the filter.
- Remove the filter housing cover and the old filter.
- Dispose of the old filter properly.
- Install the new filter, making sure it is properly seated in the housing.
- Reinstall the filter housing cover.
- Turn on the water or air supply and check for any leaks.
Granular Activated Carbon vs. Carbon Block Filters
There are two main types of activated carbon filters: granular activated carbon (GAC) and carbon block filters.
GAC filters are made of loose carbon granules, while carbon block filters are made of compressed carbon particles.
Carbon block filters have a higher density and a longer contact time with the water or air. This can result in better filtration.
However, GAC filters are typically less expensive and easier to replace.
The Mechanism of Carbon Air Filters for Trapping Gaseous Pollutants
Activated carbon air filters are a popular choice for removing pollutants and gases from the air. The mechanism behind these filters is adsorption, not absorption. Adsorption is the process where a substance adheres to the surface of another substance.
In the case of activated carbon filters, pollutants and gases stick to the surface of the carbon. Activated carbon filters have a sponge-like structure with a lattice of pores. These pores provide a large surface area for adsorption sites.
Pollutants and gases are attracted to these sites due to the carbon’s affinity for organic chemicals. As the air passes through the filter, the pollutants and gases become trapped in the carbon’s pores and are removed from the air.
Over time, the carbon adsorption sites become filled, and the filter becomes saturated. This is why it is important to replace activated carbon filters regularly. A table can be used to show the lifespan of different types of activated carbon filters and when they need to be replaced.
|Type of Filter
|HEPA Filter with Activated Carbon
|Activated Carbon Pre-Filter

Ensuring Effective Application of Activated Carbon Air Purifiers
As discussed earlier, carbon air filters are a popular method for air purification. Activated carbon air filters are particularly effective in removing pollutants like volatile organic compounds (VOCs) and odors.
However, to ensure that these filters work effectively, it is important to keep in mind a few guidelines.
Firstly, the amount of carbon used in the air filter is important. The more carbon that is present, the more sorption sites there are available to capture pollutants.
Additionally, the air flow rate and dwell time of the air passing through the filter must be taken into account. If the air flow rate is too high, it may not allow enough time for pollutants to be captured by the filter.
Similarly, if the dwell time is too short, pollutants may not have enough time to be absorbed by the carbon.
It is also important to monitor the saturation level of the filter. Once the filter reaches its saturation point, it can no longer capture pollutants effectively. Therefore, it is necessary to change the filter regularly to maintain its effectiveness.
While activated carbon filters are effective in removing many pollutants, they may not be effective in removing carbon monoxide. The EPA recommends additional measures to be taken for carbon monoxide removal.
We have included a table below summarizing the important factors for ensuring the effective application of activated carbon air purifiers.
|Guidelines for Effective Application of Activated Carbon Air Purifiers
|Use an appropriate amount of carbon in the filter
|Ensure proper air flow rate and dwell time
|Monitor filter saturation level and change it regularly
|Consider additional measures for carbon monoxide removal
By following these guidelines, you can ensure that your activated carbon air purifier is working effectively to remove pollutants from the air.
