Through these pores, we can verify absorption – a phenomenon whereby a solid attaches another substance to its own surface. On passing across the carbon, the odour present in the air is retained in the pores of the carbon, thus deodorising the air.

Naturally, when the carbon is saturated, it has to be replaced. Active carbon is used to deodorise environments and to purify toxic gases. Figeva’s active carbon is supplied in extruded pellets, or in powder form, in 10 or 25kg bags.
