Physical Characteristics:
Color: black

Our blend of 2 types of coconut-shell GAC (Premium and Catalytic) is used to reduce chemicals such as chlorine (99.9%), chemicals linked to cancer (THM's, benzene) pesticides, herbicides, insecticides, volatile organic compounds (VOC's), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water causing bad taste and odors in your drinking water.

Next, we add in Eagle Redox Alloy® (6500) to reduce scale, bacteria, and algae, even in hot water. 

Lastly, a Support Quartz is the lower strata of a filter bed and acts to support the filter medium. The maximum efficiency, the support quartz must possess the necessary attributes of hardness and be rounded or non-angular. Correct gradation and sizing must be calculated to properly support the filter media.
