Sodium Free vs. Salt System
Overall, the choice between a salt-based water softener and a sodium-free water softener will depend on your specific needs and preferences. Both types of systems can effectively remove hardness-causing minerals from water, but they do so in different ways, and each has its own set of pros and cons.
​
Sodium-free water softeners and salt-based water softeners are both types of water softening systems that are used to remove hardness-causing minerals from water. However, they use different methods to achieve this goal, which results in some key differences between the two types of systems.
​
Salt-based water softeners use a process called ion exchange to remove hardness-causing minerals from water. This process involves passing water through a bed of resin beads that are coated with sodium ions. As the water passes through the resin beads, the hardness-causing minerals in the water (such as calcium and magnesium) exchange places with the sodium ions on the resin beads. This effectively removes the hardness-causing minerals from the water, leaving it softer and less likely to cause mineral buildup in appliances and plumbing fixtures.
​
Sodium-free water softeners, on the other hand, do not use sodium ions to remove hardness-causing minerals from water. Instead, they use other methods such as catalytic media or physical filtration. These systems are also known as conditioners or descalers, they help to prevent mineral buildup but do not remove the minerals from the water.
​
One of the main differences between the two types of systems is that salt-based water softeners add sodium to the water, which can increase the total dissolved solids (TDS) level and make the water taste salty.
Sodium-free water softeners do not add sodium to the water and do not increase the TDS level, which may be preferred by some people.
​
Another important difference is that salt-based water softeners require regular maintenance, such as refilling the salt tank and cleaning the resin bed, while sodium-free water softeners typically require less maintenance.
