A potassium chloride water softener uses potassium chloride to remove dissolved minerals to soften water, while salt water softeners use sodium. People that are on low sodium diets as well as those that want to minimize the impact of sodium waste into the environment can benefit from these units.
Potassium water softeners add a healthy mineral to you water without adding the sodium. Water softeners that use potassium chloride work with the same ion exchange as salt water softeners but the hard minerals are exchanged not for sodium but for potassium. Potassium is an essential nutrient for plant life as well as human health.
However, if you have heart disease, diabetes or other medical conditions, it’s advisable to consult your physician before drinking the water softened by potassium chloride. Drinking this water while having elevated levels of potassium in your organism might lead to health problems.
Potassium chloride is commonly used as a substitute to sodium salt in water softeners. Most of the traditional water softeners using salt can also use potassium chloride.
For efficient water softening choose the best water softeners. The best model include Fleck 5600 SXT (48,000 grains) This water softeners use salt that can be substituted by potassium.
Potassium chloride for your water softener you can purchase on Amazon. They usually come in pellets and here are the products:
Diamond Crystal Potassium Chloride
This pack contains 40 pounds of potassium chloride. It can be used for all water softeners. The crystals containing low insoluble content will keep your water softener running smoothly.
Cargill Salt Potassium Chloride Pellets 7376
This package also comes with 40 pounds of potassium. It contains up to 99.1% pure potassium chloride, the crystals of which are containing low insoluble content. It’s also suitable for all water softeners.
Morton Potassium Chloride Pellets
This package includes 40 pounds bag. It’s 99% sodium free and can be used on different kinds of water softeners
Both, the sodium salt and potassium chloride, work on the same principals for softening the water. When the hard water is passing through your water softener, the ions in it are collected in the resin. Here during the regeneration process, depending on what you are using, either potassium or sodium is released into the water.
Potassium chloride is a naturally occurring mineral. It’s primary use is in agriculture. It’s also an important nutrient for humans. It plays an important role for the functioning of muscles, organs and nerves. Potassium can be found in a variety of foods as well, such as vegetables, fruits, dairy products and meat. Also potassium chloride contributes to the growth of plant life.
It’s more costly to extract from the earth potassium chloride rather than mine sodium chloride. As a result of this potassium chloride is usually more expensive. Also salt for water softeners is more available in stores. Potassium chloride can sometimes be difficult to find. Another disadvantage is that while potassium sodium does achieve good results of softening the water, it doesn’t do it as effectively as sodium. To achieve same results it takes about 30% more potassium then utilizing sodium.
Those who are following a sodium restricted diet or those who want to reduce their sodium intake might prefer or might be more comfortable using a potassium chloride water softener. On the other hand, individuals who have medical conditions must consult their doctor before drinking potassium-softened water.
