Carbon block filters: water is forced through the pores of the densely compacted carbon block, where a combination of mechanical filtration electro kinetic absorption and physical/chemical absorption take place to reduce a wide range of contaminants. Solid carbon block technology can reduce chlorine, taste and odor problems, particulate matter and a wide range of contaminants of health concern - cysts, cryptosporidium and giardia, VOC's (pesticides, herbicides and chemical), certain endocrine disruptors, THM's, heavy metals, turbidity.
