Water Softeners vs Water Conditioners

What’s the difference? Which solution is right for you?

Traditional water softening systems and salt-free water conditioning systems both address the issue of hardness minerals – calcium and magnesium - in water. The following information will help explain how they are the same, and how they are different.

Why use a softener?

The reduction of hardness in water prevents the scale buildup which can clog plumbing, fixtures, and appliances. Softened water also feels cleaner, as soaps and detergents lather more efficiently with less residue.

Salt-based (or traditional) softening systems

Water softening reduces hardness by a process called ion exchange. During ion exchange, polymer resin beads release sodium particles in exchange for hardness minerals. As sodium particles are released into the water, hardness minerals are collected on the resin beads.

When the resin beads have reached a saturation point, the cleaning cycle, or regeneration, removes the trapped minerals, flushes them through the system, and discards them down a drain line. Fresh salt water pulled into the system from the brine tank refreshes the sodium particles so that the system continues to soften.

Salt-free softening systems (water conditioning)

Salt-free water softeners, or water conditioning systems, move water through a catalytic media using a physical process called Template Assisted Crystallization (TAC). This process converts hardness minerals from their ionic form to a harmless crystalline form.

Essentially, TAC causes the hardness minerals to bind tightly together. In this stable crystalized form, calcium and magnesium do not attach to pipes, appliances, and fixture surfaces. The crystals are so small, that they are easily rinsed away by the flow of water. Because salt-free systems don’t collect any materials, there is no need for a regeneration cycle to remove trapped contaminants.

Technically, because of the continued presence of minerals, these systems do not soften the water. This process leaves water “conditioned” rather than softened.

Pros and cons of water softeners

PROs: Because salt-based water softeners significantly diminish hardness minerals, for very high hardness, they outperform salt-free systems. They also prevent lime-scale build-up on fixtures or appliances, so they last longer with fewer repairs and plumbing issues.

CONs: This type of system requires significantly more maintenance. There is also the added expense of buying salt, water wasted during regeneration, and the need to replace the resin bed every five to ten years.

Pros and cons of water conditioners

PROs: Salt-free systems require considerably less maintenance than salt-based softeners, and don’t introduce additional sodium into your water. They are also simpler to install, have minimal maintenance costs, and don’t create waste water.

CONs: These systems are not as effective as salt-based because you still have the elements that cause lime-scale build-up in your water, which means you are still exposed to them. Salt-based systems often show faster results, because filtration starts at the source the minute you begin using it. Salt-free conditioners can take longer for results to show, and are more expensive.
