Activated carbon filters remove 81 chemicals completely, including all 12 known herbicides and pesticides.Besides this, it can effectively decrease the levels of 52 other chemicals.As we also mentioned above, activated carbon can remove chemicals such as chlorine, a disinfectant that may give our drinking water an unpleasant taste and odour.In some cases chlorine may react with some pre-existing chemicals in the water to form carcinogenic byproducts.Activated carbon filters can also remove these byproducts.
It is worth noting that while carbon filters are able to remove a number of contaminants, they are unable to remove all of them.Minerals, salts and metals are some of the substances that can easily pass through the filter.However, a carbon filter, called a carbon block, can filter metal and mineral contaminants such as lead, radon, mercury, arsenic and asbestos.Additionally, it can also remove microbial contaminants. Carbon filters are great for filtering out harmful metals and minerals, but beneficial ones can slip through.Hence, among the types of chemicals carbon filters can remove, carbon blocks are the best type of carbon filter.
