Because of that, when you think about improving the water quality in your home, know that it will require level of water conditioning because each category (working water and drinking water) has different purpose in your home.

              Working water:

    Working water is used for bathing, laundry, washing clothes and cleaning. But what we called “Optimal” working water is free of:
Hard minerals (calcium and magnesium).
Iron, sulfur, manganese, tannins  (organic color) or suspended materials such as sand and silt.
Taste & odor from chlorine (chlorine may be necessary to get water safely to your home but it is undesirable to ingest or breathe in).
pH imbalances that can lead toacidic, corrosive water.
