What is a Charcoal Air Filter?

Charcoal air filters are used to remove many airborne pollutants. They are an essential component for air purifiers and air cleaners, bringing greater effectiveness to removal of odors and volatile organic compounds.

They might seem complicated, but activated carbon uses fairly simple principles to enhance the air quality in your home.

These are simply filters made with activated charcoal, also known as activated carbon, which is carbon materials that are processed through a highly precise method that produces a product that is extremely porous and has a high surface area. While the exact numbers will vary based on the source material and the production method, a single spoonful of activated charcoal can have a surface space equal to a soccer field!

Charcoal air filters, such as the Erik Carbon Pre-Filter or EJ120 carbon pleated, are essentially box filters that contain activated carbon. By using charcoal as a filtering media, the overall effectiveness and performance of the product is enhanced, making it more effective for gases and odors in your home.
porous activated charcoal
Activated charcoal is made from many different materials, including nut shells, wood, peat, and coconut shells. The material goes through a manufacturing process that first removes organic matter, which creates the pores that give the material such high surface space. Next the material is “activated,” which is done through a chemical process or other methods. The activation enhances the material’s ability to grab and hold microscopic materials.

They are not only used in homes, they can be used for a cabin air filter in a vehicle.


Why is Activated Charcoal So Effective at Filtration?

  • Can Remove Many Gas or Chemical Contaminants: Many any airborne contaminants can be filtered out by activated charcoal air filters used in air cleaners. From smoke particles to vapors, most gases in your indoor air will be adsorbed by a carbon filter air purifying machine.
  • Extremely Large Capacity: Another reason why activated charcoal filters are so effective in air purifying is their ability to remove a large amount of contaminants by volume. As we discussed earlier, activated charcoal has an extremely high surface space per volume, and this high surface space allows the material to grab on to particles that might otherwise pass through other filtering substances.
  • Works Effectively Under Various Conditions: Activated charcoal, when properly treated, also remains consistently useful even under different conditions. Changes in temperature, humidity, and other atmospheric changes rarely have a noticeable impact on the overall effectiveness of the materials. This means that no matter where you use it, no matter how hot or cold you keep your house, no matter what the humidity level at the time, the activated carbon filter remains consistently effective and can remove smells like mold odors.
  • Safe to Handle: Activated carbon air filters are also safe to handle. It is inherently inert, meaning it is stable and un-reactive with other substances. It is safe to handle in your home and can be used in various locations, such as the office or commercial settings, without concern.


Activated Charcoal In Addition to HEPA Filters

To understand air purifiers, we need to differentiate between activated charcoal air filters and HEPA filters.

HEPA filters are a type of filtration system that has been rated to trap small and large particles. This includes dust, pollen, mold spores, pet dander, etc.

To be classified as HEPA (which stands for High Efficiency Particle Air), a filter must remove at least 99.97% of all airborne particles that are a certain size or larger. HEPA filters are made from thin fibers of glass or synthetic fibers. The fibers are formed into a paper-like material, which is folded to increase surface space; because of the folding, some HEPA filters hold as much 40 square feet of material.


Oransi Air Purifiers that Use Charcoal Air Filters

EJ Air Purifier

The EJ air purifier is one of the most powerful and effective units for cleaning the air in large areas, including basements and large living areas. It achieves outstanding efficiency and effectiveness through a wide range of advanced technologies, but one of the most important materials is the charcoal air filter.

This air purifier uses two filters to remove toxins and air pollution, the first of which is a proprietary charcoal filter for gas control. It has a pleated activated carbon filter that is 1-inch deep, as well as a 3-inch-deep main HEPA filter. Combined, these two filtration methods allow the EJ to remove smoke and gas.


Erik 650A Air Purifier

Made for residential locations, as well as healthcare and office facilities, the Erik 650A has technologies that allow it to perform to a high standard. It also uses two filters, starting with a 4-inch deep filter that has activated carbon, which enhances the filter’s capability. The air then goes through a 12-inch-deep main HEPA filter, which results in some of the most efficient purification on the market.

The Erik Carbon Pre-Filter combines the dust-trapping capabilities of a pleated filter with the odor-removal qualities of activated carbon.


Finn HEPA UV Air Purifier

The Finn is a smaller, more compact air purifier, but thanks to advanced technology and superior designs, it remains a highly capable machine that can remove up to 98% of airborne allergens, including dust, pollen, and pet dander. This machine is small compared to others, but it uses numerous technologies, including HEPA filters, UV light, and (you guessed it!) charcoal air filters.

The charcoal air filter in this unit is used in the pre-filter stage, which assists in the removal of light odors, making the Finn a well-rounded machine for use in bedrooms, bathrooms, offices, and other small spaces.
