Greensand Whole House Water Filter Specifications
Water goes through 3 stages of filtration.
In Stage 1, water flows through a 20"x2.5" sediment pre-filter that removes sediment, dirt and silt. This water filter also extends life of the main unit
In Stage 2, water flows through a large 5' mineral tank that contains Manganese, Iron and Hydrogen Sulfide reducing Greensand media.
In Stage 3, water flows through a 20"x2.5" solid carbon block filter cartridge. Carbon (also called Charcoal ) has been used in water filtration for centuries. It effectively removes or reduces many contaminants including Volatile Organic Compounds ( VOCs ), insecticides, pesticides and industrial solvents.
