The 10 stages include:
- Stage 1 – 30-micron sponge filter which removes larger solids (sediments) such as rust.

- Stage 4 – 30 cubic inches of ultra-fine mesh, superior coconut shell, and granulated activated carbon. Granulated activated carbon has long been accepted by the E.P.A. and others as the premier, cost-effective way to remove chlorine, bad odors, 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 which removes lead to below minimum E.P.A. standards.
- Stage 7 – An additional 30 micron felt pad provides an extra buffer against floating sediment of any kind.
- Stage 8 – 7 cubic inch bed of G.A.C. which provides extra protection against cancer-causing organic pollutants.
- Stage 9 – 2 oz. of calcite which raises the water’s pH and lowers acidity. It also increases alkalinity, which many nutritionists recommend.
- Stage 10 – 1-micron absolute depth filter. A filter with a micron rating this small screens out cysts and protozoa, (including Giardia and Cryptosporidium), and gives the filtered water a sparkling clarity
