 1st Stage:
This10" 5micron sediment filter of 100% pure polypropylene fibers. High capacity filter removes particles as dusts, dirt, silt, mud, algae, bacteria, to get clear, odorless water and protect membrane against fouling.

 2nd Stage:
Granular Active carbon composed of high-performance activated carbon that removes remove up to 99% of lead, Cryptosporidium, Giardia, chlorine, turbidity, organic contaminants, pesticides VOCs, TOCs and other chemicals causes unpleasant smell, odor, color.

 3th Stage:
Carbon Block 5 micron 10" -- gets rid of unpleasant chlorine, tastes and odors, cloudiness and colors. Carbon block is vital to preserve the membrane from chlorine.
 
 4th Stage:
Made in USA. High rejection TFC type membrane with the capacity of producing 75 gallons per day. This membrane removes the following hard water contaminants that may be present in your water: lead, cooper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, nitrate, and selenium

 5 th Stage:
12" Inline Post Carbon Filters NSF approved. This post carbon filter is designed to improve taste. It removes any residual impurities and odors from the tank and provides a finer polishing of pure water.

 6 th Stage:
This filter improves the qualities of clean water by adding necessary for proper human development and health minerals, such as Calcium, Magnesium, Sodium, Potassium and others readily found in many natural mineral waters, and readjust the alkalinity of the water
