Stage 2- 8 oz. of KDF-55. KDF-55 is a patented alloy. It removes free Chlorine and some Heavy Metals, thereby prolonging the life of the filter and is an excellent Bacteriostat.
Stage 3-10 micron felt pad. Removes smaller floating solids and separates the layers, preserving their integrity.
Stage 4- 30 cubic inches of ultra fine mesh superior coconut shell Granulated Activated Carbon, G.A.C.. G.A.C. has long been accepted by the E.P.A. and others as the premier, cost-effective way to remove Chlorine, bad odor and color from drinking water. G.A.C. also removes Organic Contaminants such as Pesticides, Herbicides, Arsenic, Mercury and Trihalomethanes, a Cancer-causing Organic Pollutant.
Stage 5- 10 micron felt pad for Fine Sediment Removal.
Stage 6- 7 cubic inches of ion exchange resin.This resin has an exceptional affinity for Lead, and removes Lead to below minimum E.P.A. standards.
Stage 7- Additional 10 micron felt pad provides an extra buffer against Floating Sediment of any kind.
Stage 8- 7 cubic inch bed of G.A.C.. Provides extra protection against Cancer-causing Organic Pollutants.
Stage 9- 3 oz. of calcite. Calcite raises the water’s pH, which lowers acidity and increases alkalinity, which many nutritionists recommend.
Stage 10- 1 micron absolute depth filter. A filter with a micron rating this small screens outcysts and protozoa, (including Giardia and Cryptosporidium), and gives the filtered water a sparkling clarity.
