Water softeners improve the “working water” throughout the home (water used for bathing, cleaning, laundry, etc.). Softeners are not “purifiers” and are not designed to improve drinking water.
We do have a combination system that will soften and remove chlorine, odors, and tastes from the water (whole house filtration). This would give you drinkable water throughout the home that is similar to having a refrigerator filter on the whole house. It does not reduce a wide range of potential contaminants.
The water in our area also contains high levels of total dissolved solids (TDS). Many consumers want to purify their “consumable water” for drinking, cooking and ice cubes. This provides the highest quality water right at the kitchen tap and reduces contaminants and TDS.
