Carbon Air Filters: What They Are, How They Work and Why You Should Choose Them

September 02, 2019



When it comes to effective air cleaning and filtering, one of the options that enjoys extensive use is activated carbon filters

The reason for this is not far-fetched. Given the natural ability of this type of air filters to remove unwanted particles in a medium such as air and liquid, it is just natural that many will tend towards using one.

However, that does not explain anything about them, or why they work. That is why we have put up this article to help you understand the critical aspects to know about carbon filters.

What is carbon air filtering?

As the name implies, this is the process of removing the impurities in the air by using a sample of activated carbon.

This is made possible due to the presence of a considerable surface area on activated charcoal which provides wide active sites where contaminants can bond together. Looking at that model of operation, it can be said that the process of carbon air filtering works by chemical adsorption.


Why are carbon filters called “activated”?

Naturally, carbon might be useful for trapping contaminants in the air, but it doesn't go seeking them out itself. There must, thus, be a way it brings these impurities closer to itself to have them on its large surface area in the first place. 

One way to make that happen is by inducing a positive charge on the surface of the carbon. That way, the carbon air filtration system can attract the negatively-charged air particles, creating a much safer environment.

Likewise, activated carbon is not like any natural substance anymore. It has been specially processed and engineered to have a larger surface area while being more porous than what would have been normally obtainable. 

All of these contribute to making the carbon filter a better absorber.


What properties of carbon makes it highly desirable?

There are a lot of reasons why carbon has found broad applications in the air filtration industry. Some of these include but are not limited to:

● Carbon has the capacity to collect almost any contaminants in their gas form;

● Carbon also comes with a large capacity for organic molecules, primarily when they occur in the solvent form;

● It will not only absorb a large amount of chemicals at any one time, but it has the tendency to retain them too;

● Carbon has been proven to be a good agent at catalytically destroying ozone (which is one of the main components of smog);

● Carbon performs very well under a wide range of temperature and pressure conditions;

● In line with adsorbing chemicals and air particles, carbon is also great at trapping odors and keeping the air fresh.
