Salt based softeners do add a small amount of salt to water, we recommend using potassium.
Since potassium chloride contains potassium, a nutrient known to help plants grow, they are considered more environmentally friendly than sodium chloride.
The backwash cycle will not harm grass or landscape like salt
This type of soft water will also be good for watering household plants, which is not recommended for water softened with sodium chloride.

A salt based system may have a minor effect on blood pressure
Also potassium can affect certain heart issues.
Check with your Dr if you have a heart related issue

TDS total disolved solids here average about 200PPM, the only way to reduce TDS is to add a Reverse osmosis unit.

One last point Hard water does not have any harmful effect so a softener is not mandatory,
it an option.

The most important addition is the Nova Whole house water filter only $695, this should be a priority.
