How Activated Carbon Works to Filter Your WaterActivated carbon or AC, works by attracting and holding certain chemicals as water passes through it. AC is a highly porous material, therefore it has an extremely high surface area for contaminant adsorption.( Adsorption is the phenomenon whereby molecules adhere to a surface with which they come in contact with. When water containing soluble organic materials comes into contact with the granular activated carbon it selectively removes these materials by adsorption.)  AC is made of tiny clusters of carbon atoms stacked upon one another. The carbon source is a variety of materials such as peanut and coconut shells or coal. the raw carbon source is slowly heated in the absence of air to produce a high carbon material. The carbon is activated by passing oxidizing gases through the material at extremely high temperatures. The activation process produces the pores that result in such a high adsorptive rate.Laboratory Test results show these filters are very efficient at removing impurities such as chlorine, bacteria, amoebas, suspended solids, organic pesticides, some heavy metals, bad tastes and smells. They will remove 99.99% of Giardia and Cryptosporidium. 98% Suspended Solids99.999% of Giardia99.999% of Cryptosporidium
