Charcoal block filter removes chlorine, taste and odour, and organic chemicals. The origin of the charcoal imparts on it some qualities due to the mesopores and micropores they contain, their distribution and the temperature at which they were produced. These filters have high flow rates and offer low differential pressure between inlets/outlets. The contact time between the water and the carbon block is long enough to permit an efficient exchange cartridges are produced in a controlled environment and manufactured according to ISO9001. Our patented technology imparts on these Carbon filters different qualities such as removal of heavy metal ions or endocrine disruptors or pharmaceuticals or hydrocarbons as per request.
