Modern in-line cartridges with coconut shell granulated activated carbon. It removes undesired contaminants from water extremely effectively and improve water taste and flavor.
Due to its porous structure, carbon is perfect for filtering purposes. Contaminants which can be found in water and which flow though activated carbon are intercepted (adsorbed) in pores and, as a result, water gets purified and free of toxins that could pass through to the distillation process. It may also be placed after the distillation process, which will give a better lifespan and perhaps even better tasting water.
Any filter is also a perfect place for bacteria to live and grow. Change the filter often and make sure to flush the new filter untill the carbon dust is flushed out. It is not harmful, but doesn’t look good.
