Saltwater purification systems produce small amounts of pure sanitizer derived from natural salt, just enough to purify the water. Salt systems are a desirable alternative to packaged bromine or chlorine, and can provide naturally clean, crystal clear and more pleasant water for bathers. The water actually feels better!

Not just for pools anymore!

For years, the benefits of saltwater have been enjoyed by swimming pool owners. Salt systems have proven to be safe, effective and eco-friendly. And now, this next-generation technology is affordably available for hot tub spa owners.

Safe for the environment
Earth Friendly

While some marketers tout salt systems as chemically free, that's really not honest advertising and misses the point. We live in a world of chemistry, and life itself could not exist without chemicals. Salt is a chemical. Water is the most common chemical on our green Earth's surface! Salt systems are an advanced method to utilize natural chemistry in a better way.

Many people previously convinced that they had an allergic or other aversion to chlorine, found no such problems after switching to a salt-based system. Perhaps the additives in packaged chlorine were more to blame. In any case, a salt system allows the user to more precisely control the sanitizer output, often requiring lower levels to achieve water purity. The mineral salts have many health benefits of their own, as explained below.

How a Salt Water Spa System Works

Salt is sodium chloride (NaCl). Through a controlled process in a low-current electrolysis cell, chlorination is produced in just the right amount to sanitize spa water.

As saltwater enters the cell, a safe, low-voltage current passes between special rare-metal plates, producing pure chlorine (Cl) from the saline solution. In water the chlorine instantly becomes hypochlorous acid (HOCl), which is its disinfecting form.

In conjunction with its control unit and programmable timer, the Saltron Mini Spa cell pictured here will sanitize your portable hot tub. It is incredibly efficient, using only about as much energy as a 50-watt light bulb, often running less than an hour a day.

Saltron Mini is simple to install in about 10 minutes, without tools or any modifications to your spa. It is completely compatible with ozone, and in fact enhances the water quality of ozonator-equipped spas. As with any system, properly balanced water is essential.

The Salt System: recycles itself

You're probably wondering how often the salt needs to be replenished. One of the beauties of these systems is that as the hypochlorous acid is used up, the chlorine recycles back into salt. So with a salt chlorine generator, the salt only has to be topped off occasionally due to hot tub water splash out, and replenished when the water is changed. Very economical!

Salinity Levels: lower than you think

When we think of saltwater, the ocean usually comes to mind. Seawater has a strong salty taste of course, and it can cause metal corrosion. So you might be wondering if salt systems are safe for spa equipment. Fortunately, the levels of salt used with spa systems are very low by comparison, and safe for equipment.* The table below shows some approximate saline levels to give you a perspective:

Salinity Salinity Comparison - parts per million
Ocean Water 35,000 ppm
Human Tears 9,000 ppm
Ability to Taste Salt 5,000 ppm
Modern Salt Pools 3,000 ppm
Typical Spa Salt System 2,500 ppm

In fact, at the low saline levels typically used for spa chlorine generators, most people cannot even taste the salt. The salinity and chlorine levels are easy to check with our highly accurate AquaChek brand Salt and Chlorine Spa Test Strips. Note: severe over-chlorination can damage equipment over time, so monitor your chorine levels and adjust your system accordingly to maintain recommended sanitizer levels.

*Refer to your spa owner's manual and warranty.

Dead Sea Minerals: a better salt

Your choice of salts is very important. Common table salt, rock salt and ice-melt contain anti-caking agents and other additives and impurities which can foul the electrode plates of a chlorinator, so avoid those types.

We offer a special grade of authentic Nexa Dead Sea Mineral salts, refined for use in salt chlorinators (or which can be used alone). This natural product contains not only the necessary sodium chloride, but other beneficial minerals not found in common salt.
