In recent years, activated charcoal has become increasingly popular due to its ability to absorb various substances. One of the most significant uses of activated charcoal is in air purification. But what exactly does activated charcoal absorb, and how does it work? In this article, we will explore the topic in-depth and provide you with all the necessary information.

What is Activated Charcoal?

Activated charcoal is a form of carbon that has been treated with oxygen to create millions of tiny pores between the carbon atoms. These pores increase the surface area of the carbon, making it highly absorbent. Activated charcoal is commonly used in air and water purification, as well as in medicine and skincare.

How Does Activated Charcoal Absorb Gas?

Activated charcoal works through a process called adsorption. Adsorption is the process by which molecules adhere to the surface of another substance. When gas molecules come into contact with the surface of the activated charcoal, they stick to the surface of the carbon pores, effectively trapping them. This process removes the gas molecules from the air, leaving behind cleaner, fresher air.

Which Gases Does Activated Charcoal Absorb?

Activated charcoal can absorb a wide range of gases, including volatile organic compounds (VOCs), formaldehyde, nitrogen oxide, and sulfur oxide. VOCs are chemicals that can cause respiratory problems, headaches, and other health issues. Formaldehyde is a common indoor air pollutant that can cause irritation of the eyes, nose, and throat. Nitrogen oxide and sulfur oxide are both common pollutants found in car exhaust fumes.

Benefits of Using Activated Charcoal for Air Purification

Using activated charcoal for air purification has several benefits. Firstly, it is a natural and chemical-free way to purify the air. Unlike other air purifiers, activated charcoal does not release any harmful byproducts into the air. Secondly, activated charcoal is highly effective at removing harmful gases from the air, making it an excellent choice for people with respiratory problems. Finally, activated charcoal is relatively inexpensive and easy to use.

How to Use Activated Charcoal for Air Purification

To use activated charcoal for air purification, you will need to purchase activated charcoal filters or bags. These filters or bags can be placed in areas of the home where air purification is needed, such as in the living room or bedroom. The activated charcoal will absorb the gases in the air, leaving behind cleaner, fresher air. It is important to replace the filters or bags regularly to ensure maximum effectiveness.

Precautions When Using Activated Charcoal

While activated charcoal is generally safe to use, there are a few precautions that you should take. Firstly, activated charcoal should be kept out of reach of children and pets, as it can be harmful if ingested. Secondly, activated charcoal can create dust, which can be irritating to the eyes and respiratory system. It is important to handle activated charcoal with care and to wear a mask when handling it.


Activated charcoal is an effective and natural way to purify the air in your home. It is highly absorbent and can remove a wide range of harmful gases from the air, making it an excellent choice for people with respiratory problems. If you are looking for a chemical-free and natural way to purify the air in your home, consider using activated charcoal filters or bags.
