Sometimes you will notice the smell; sometimes you will not. You can follow the manufacturer's guidelines and change it on a regular basis, although this is just a rough estimate. The carbon becomes saturated depending on how heavily it is used and the amount of pollutants it is exposed to. Replacing ...Reactivation of granular activated carbon, types and ...· It is a widely used method for recovering solvents in air currents, since the molecules released maintain their original structure. Carbon is subjected to alternative adsorption-desorption cycles. In the first cycle, the solvent is retained until the carbon is saturated.
