Our filter systems are designed to be used with Activated Carbon, as Activated Carbon filtration is the final, important procedure in producing a high-quality spirit such as vodka. Note that filtering strips and neutralizes the spirit, so it is not typically used when the desired product must retain characteristics achieved during fermentation, such as whisky.
There is a method that will both improve the quality of the filtered product and increase the amount of product that can be filtered through your carbon. Brewhaus offers a free, downloadable book explaining in-depth information about activated carbon and methods of use that can increase the effectiveness of activated carbon filtration by 100-150%.
