The Filter Carbon Cartridge is used in the Inline Filter and the EZ Filter. Alcohol should be diluted to below 50% ABV as the carbon does not work as effectively if its above this. Each cartridge will do at least 20 litres of diluted alcohol and should be activated before use by running it under hot water for several minutes (or can be left in water for a few hours). The idea behind this is to remove any air trapped in the carbon which prevents effective treatment. Once used they should be thrown away.
