How Activated Carbon Air Filters Capture Contaminants?

Tyd: 2022-06-29

Activated carbon air filters remove contaminants from the air through a process of adsorption, which is different from absorption.

The key to the difference between the two is that:In the adsorption process ofgeaktiveerde koolstof lugfilters, the pollutants stick to the outside of the carbon; while in the absorption process, the pollutants are absorbed inside the structure itself, just like a sponge absorbs water, the water does not chemically bond with the sponge, it just fills up the space inside it.

Carbon ingeaktiveerde koolstof lugfilters is a lattice of interconnected carbon atoms. When a molecule of some gaseous substance passes through the carbon, it can adhere to the surface of the carbon bed, provided that it is activated to generate adsorbable sites. During the adsorption process of anactivated carbon air filter, gaseous contaminants gradually fill the adsorption sites of the activated carbon. Once the carbon bed is saturated, the filter can no longer capture the contaminants.

Ook,geaktiveerde koolstof lugfilters have chemicals with greater affinity for adsorption sites that can replace chemicals with less affinity, and the affinity of a given chemical for the adsorbent is highly dependent on environmental conditions, such as temperature and relative humidity.

Therefore, as conditions change, different chemicals may be released from the filter. When anactivated carbon air filter is saturated, you may notice that it gives off a strange odor. This is a strong indicator that it is time to replace your carbon filter.
