Activated carbon filters serve to clean the air and water. Harmful substances adhere to the porous surface of the activated carbon. Activated carbon filters are used, for example, in range hoods, car pollen filters, air conditioning units, cigarette filters, hard drives, and many other applications.

Activated Carbon

Activated carbon is a type of fine-grained carbon with a relatively large surface area. The larger the surface area, the more harmful substances and odors are bound to the activated carbon.

Mode of Operation

Activated carbon filters are mainly used as air or water filters. They are designed to filter harmful substances such as solvents and pesticides. Organic substances accumulate on the surface of the activated carbon, thus cleaning the air that exits the filters. When too many harmful substances accumulate in the filter, its efficiency decreases. Therefore, the activated carbon should be replaced regularly. The replacement interval depends on the volume of filtered air and the concentration of harmful substances.

Use of Activated Carbon Filters

Activated carbon filters are often found in factories for cleaning exhaust gases and wastewater. They are also found in cigarette filters and car pollen filters. Additionally, the filters are used in air conditioners, in agriculture, and in gas masks.

Many manufacturers incorporate activated carbon filters in range hoods. Regarding the air recirculation function, they filter odors from the air. However, the pores of the activated carbon often become clogged with greasy substances. It is important to regularly replace the filter and renew the carbon to ensure that the air continues to be freed from substances and odors.
