In active condition, carbon has an enormous surface and therefore it can be used for deodorisation of gasses. Carbon filter-elements are used to protect the driver against the inhalation of specific toxic vapours. Freshfilter supplies active-carbon filter-elements in conformity with the ABEKHg-classification in the most common sizes. Below you can find detailed information regarding the type of carbon the polluted area requires:
| A | Aromatics en PAH’s, organic vapours, BTEX. |
| X | Aromatics with a boiling-point below 65°C |
| B | Anorganic substances: chlorine, cyanide, etc |
| E | Sulphour dioxyde and anorganic acid vapours |
| K | Ammonia |
| Hg | Mercury |
Replace the carbon elements every 9 weeks at minimum. Always place a dust filter-element in front of the carbon filter-element for protection. When the PPM exceeds the 5PPM or when odour pollution is notices, always replace the carbon filter-element!
