Do You Use a Whole House Water Softener?
Water Ionizers should not be used in conjunction with high levels of sodium, such as with water softeners very much. Here's the reason and solution for the problem:
Water Ionizers: Sodium, Water Softeners
If you use a sodium or potassium based water softener [or if you live in an area that has very high levels of sodium in your water] you most likely shouldn't hook up to a water ionizer with that water. There are ways to pre-filter the sodium out of the water, and the most customary way is to use a reverse osmosis system. If you do already have a reverse osmosis unit, then make sure you use a remineralizer filter with it. If you don't already have RO [reverse osmosis] I encourage you to get ours, because it comes already configured with a remineralizer.
Sodium is an abrasive mineral and it's also electrically conductive. Because it's also highly alkaline it will concentrate in your alkaline ionized water, possibly making your ionized water too salty for healthy consumption. Too much sodium in your diet can be unhealthy especially if you have high blood-pressure or other health condition.
Note: If your water is too terribly hard [over 250 ppm of hardness]...we suggest you use the reverse osmosis option.
