Discover the properties of activated carbon

Cabin filters can be divided into standard filters and filters with an additional layer of activated carbon that is placed between two layers of non-woven synthetic fabric of the filter medium.

Activated carbon filters, like standard filters, stop solid particles, but thanks to the special properties of activated carbon, they also absorb unpleasant odours and harmful gases such as ozone, sulphur dioxide, and nitrogen oxides.

For most car models you can purchase both a standard filter and an activated carbon filter. It is important to choose activated carbon filters because their properties increase the comfort of travel and additionally protect our health.

What is there to know about activated carbon?

Activated carbon has a porous structure similar to a sponge. The pore diameter of individual particles is more than 10,000 times smaller than the diameter of a human hair. Thanks to the porous structure, the activated carbon has a very large surface area. If you take just one spoon of activated carbon and count the surface of the channels of all its particles, it would turn out that the surface area of ​​that little bit of carbon is equal to the area of a football Pitch.

Activated carbon has adsorption properties, which means that it binds chemical molecules, such as gases.

Thanks to the adsorption properties and the large surface area of ​​carbon particles, cabin filters with activated carbon can stop harmful gas particles throughout the whole service life of the filter.

How is activated carbon created and where is it also used?

Activated carbon is obtained from a variety of different source materials containing carbon. One of the commonly used materials for the production of activated carbon are coconut shells which are charred at very high temperatures.

There are many types of activated carbon that differ from each other in the way they are produced, the size of their carbon particles, and their purpose. Activated carbon has many industrial uses (e.g. in cigarette filters or in refrigerators), but it is also used in medicine (for the treatment of diarrhoea, indigestion and flatulence).

Briefly: The properties of cabin filters with activated carbon increase travel comfort and additionally protect our health.
