Reverse Osmosis systems are the most common type of purification in Arizona.
This is because of the high levels of total dissolved solids in the valley.
Dissolved solids vary in different areas but typically range from 400
parts per million to over 1000 parts per million. For those on shared
or private wells, the dissolved solids can go much higher. These units
involve a multi-stage filtration process and usually fits underneath the
kitchen sink. The unit supplies water to a storage tank and many times
feeding a refrigerator depending on the layout of the kitchen. Water from
your municipal supply or tap goes through a sediment filter to remove
large particulates. Reverse Osmosis units also have a carbon filter to
remove organic materials and chlorine. Chlorine removal is important in
Arizona as the municipal supply uses high levels to kill bacteria in the
water. A semi-permeable membrane is used to remove the inorganic ions
of salts and metals that reside in Arizona water. Sometimes there are
additional filters needed for further processing of the water. Many Reverse
Osmosis units have different configurations. Before you purchase any form of
