Generally many multi-stage filters of any type can contain at least one layer of GAC as a filter stage. Here is the same for all shower filters. Yet it's not merely water filter that can be accomplished through applying GAC, it also can filter; fuel, oils, substances and can also be used to treat poisonings and overdoses simply by investing it. As a filter it is a real miracle solution, no wonder it is applied so much.
This kind of filtration medium could be the fantastic child of the bath filtration earth (it practically is fantastic in color as well!). KDF is really a patented filtration medium discovered and created by the business KDF Water Treatment Inc. situated in the USA. The moderate was found by Don Heskett in the 60s and ever since then has gone onto be recognised and utilised by many government bodies such as the United Claims Environmental Safety Company - who classify it is really a'pesticidal product'due to it's good ability to kill bacteria and other microorganisms.
KDF is stated in a way that uniquely combines copper and zinc, that mix creates a fine fantastic mud like material that creates an electrochemical effect when water passes through it. That reaction improvements the chemical make-up of the dangerous materials in water (such as compounds like chlorine) and converts them in to benign elements which are not harmful. Also that response causes heavy materials in the water to dish out (stick to) the medium's area, thus removing them from the water. Dangerous microorganisms such as for instance algae, fungi and germs are also straight away killed when they touch KDF.
