Best Water Softener Salts For Your Water Softening System in 2019

Best Water Softener Salts

When water falls from the sky, it is relatively pure. However, it can seep through the ground and into waterways, picking up impurities along the way. Calcium carbonate is a particular culprit for increasing water hardness.

Water softeners counteract the “hardness” by using salts that interact with con-tributing ions. Potassium or sodium chloride pellets both trap these ions and thereby remove their effect.

In turn, the type of softener salt is just as important as its chemical composition. Here, we’ll go through just a few of the brands available and why you’ll love them.

Here are our reviews for six of the water softener salts that are on high-demand for their quality, efficiency, and health benefits.

1. Diamond Crystal Water Softener- 40 lb. Bag

  • Crystals made from potassium chloride, for a variety of purposes .
  • Naturally made and dried via sun, wind, and time.
  • Results in great-tasting soft water that’s also perfect for sensitive skin.
  • Helps prolong the life of pipes, appliances, and softening systems.

The Good

It is made of potassium chloride, an all-around better choice compared to sodium chloride used in most other brands.This pure product is also NSF certified, so you can be assured of its quality and ability to do what it claims.

Not So Good

We feel the price could have been a little lower, for salt. A few consumers have said the bag doesn’t last quite as long as a bag for sodium pellets.



Overview

An environment, health, and appliance-friendly alternative to the every day sodi-um chloride used in most softening salt pellets. This is one of the purest salts you will find for softening your water, and also one of the few to be NSF certified.

In addition to simply softening water, it also extends the life of appliances and re-duces film build-up on sinks and showers. The product is designed with your con-venience in mind as it even comes in a 50% recycled material bag that is easy-to-open.

99.1% Potassium Chloride Crystals

Potassium chloride is a lot harder to find than sodium chloride and is known to be the “higher quality” salt. Due to the high sodium content already in our diet, add-ing NaCl to our water supply can be bad for our health.

Potassium chloride is the better choice for both drinking and watering plants. Its use as a water softener leads to clean-tasting water without a trace of saltiness.

Designed With Your Health (and Convenience) in Mind

This product is recommended for all types of water softeners. It is made naturally using sun, wind, and time to dry potassium chloride solution into crystals.

This results in a 99.6% pure product that can get rid of hardness in your water without compromising on health and taste. The product also comes in an easy-to-open bag that is made of 50% recycled material and comes with an easy-grip handle.

NSF Certified

One thing that is commonly noted about this product is it can produce virtually tasteless soft water. For this reason, it is certified (ANSI Standard 60) as safe to use for drinking water.

While the salt is not advised for direct addition to food products, when dissolved and filtered properly, it can even be used in meat, poultry, or other food uses.

2. Morton Salt Clean-Protect Water Softener-50 lb. Bag

Proper use is said to result in pure-tasting water or close enough that the salt cannot be detected. The Clean-Protect formula signifi-cantly reduces buildup in pipes and appliances without affecting your health. Those who use this salt for laundry, dishwashing, and showering have no com-plaints with regards to the sodium in their water.

Patented Clean-Protect Formula Protects Appliances

This product is created with a special patented formula that helps reduce scale build-up in water heaters and pipes. Such build-up can become a huge problem especially for less soluble salts, such as rock salt.

With this highly soluble formula, you can expect your water softener to remain in great condition for a long time.

Fit for Drinking Water*

This is the go-to salt if you want your water softener to produce drinking water. It is good enough for even those on a low-sodium diet. It differs from standard so-dium chloride pellets which almost triple the amount of sodium in water.

Many have said that they taste almost no difference in their drinking water. In addition, it can leave skin and hair feeling softer and make dishes much easier to clean.

Convenient Usage

How to Buy a Water Softener Salt

While they may all seem quite the same, not all water softener salts are created equal. They can come in many different varieties and composition.

In addition to overall quality based on source and manufacturing, the chemical composition in the salts can also determine whether they are fit for use with drinking water.

The best softening salts are those that are versatile, work great with every soften-er, and leave very little taste in your water. It can be hard to find a salt that can give you all these benefits.

Fortunately, we’ve been doing our research and can help you know what to look for. Here are some things you should keep in mind when buying some softening salts to use in your water softener.

Chemical Composition

The majority of water softening salts will be made of sodium chloride, the chemi-cal name for table salt minus all the additives.

This mineral is naturally occurring and easily found in salt minds or solar evapora-tion ponds. As brine solution with sodium chloride washes over the resin tank in a softener system, hard mineral ions like calcium and magnesium are replaced with the sodium.

The hard ions then replace the microscopic excavations left by the sodium ions and are “trapped” in the salts. It is useful for most applications but may not be the best choice for drinking water since it can increase your sodium intake by as much as three times your regular intake.

Potassium chloride is a more recent addition to the choices available. It can be considered a healthier alternative for those who want to soften their drinking wa-ter.

This salt is also found in nature, though its primary use is in agriculture. It works the same way as sodium chloride but softens the water with potassium ions in-stead of sodium. It is beneficial for health in most cases since potassium is re-quired for proper organ, nervous, and muscular function.

Many people also face challenges in getting the adequate potassium they need from green leafy vegetables, dairy, lean meat, and fruits such as bananas. So hav-ing potassium in the drinking water can be an added bonus.

However, since extracting potassium is more difficult than mining sodium chlo-ride, the cost can be considerably higher.

Special Features

With technology constantly reforming itself, many water softening salts don’t just stick with softening your water anymore. As you may have seen in this review, there are salts that help clean and protect your pipelines and appliances (tubs, faucets, etc.).

There are also salts that help fight against rust buildup and remove excess iron in water. It’s important to think of whether these are necessary in your case and get the type of salt you need.

Crystals vs. Pellets

Whether you buy your salt in crystal or pellet form can also affect how well they work with your softening system. While both will work, crystals tend to be smaller and more compact. They dissolve faster in the brine tank and take a long time be-fore causing build-ups.

They are also usually made from evaporated seawater. That way, you can be sure (in most cases) that if you have crystals, your product comes from nature.

Any type of salt can be made into pellets, but usually they consist of evaporated salts. These are more processed and fully evaporated. They also take a long time to cause build-ups but are more likely to contain additives. On the bright side, most of the additives are FDA approved or NSF certified, so you can still be as-sured your soft water is safe to use.

Purpose

In order to find and buy the right salt for your needs, you also need to make sure whether you just want something for your dishwasher or intend to drink your softened water.

Dishwasher salt is different from table salt and the salt used in regular water sof-teners. It is much coarser and doesn’t get in the way of regular cleaning opera-tions.

There’s no mess involved if used correctly and they are necessary to prevent clog-ging. Smaller grains will get stuck easily and cause quite a problem.

Dishwasher salts are also the closest to 100% sodium chloride without any other additives. Food-grade salt is used since it’s expected that you’ll be eating from your newly washed dishes.

If you want to have water that you can use to water plants, do the laundry, and even brush your teeth, sodium chloride is the best choice. It’s quite cheap and you won’t need to worry about adding a substantial amount of sodium to your diet.

Of course, if your plants are sensitive to sodium, you may need to switch to potas-sium chloride. Otherwise, you are all set.

Last but not least, if you do plan to drink your water, be sure to use potassium chloride especially if you are monitoring your sodium intake. The taste is also much less noticeable. Your health and tastebuds will thank you.

Budgeting

Since you’ll need to replace your salt at least once every three months, you have to determine how much you are willing to spend. Obviously, purchasing fifty pounds of salt from a company from the other side of the country will cost you a great deal more than purchasing locally.

Choosing potassium chloride over sodium chloride can also raise how much you need to pay for your water. As mentioned before, this may still be worth it if you’re drinking that water. Purchasing from small businesses which sell their items at a wholesale price can also save you money.

FAQs

Fifty pounds of salt is too much for me at once. Are there any smaller sized bags I can purchase?

For sure! While some brands come in only one size, there are quite a few with more than one to choose from. For example, the Morton Clean and Protect comes in 25, 40, 44, and 50 lb. Bags.

This is especially helpful if you know you won’t be using that much since you only need a little softening. Most of the Diamond Crystal products are also available in both 40 and 50-pound bags. Be sure to go on the manufacturer’s official website to check all of the choices for size available.

Is the taste left behind by the sodium (or even potassium) ions really that noticeable?

The taste left behind by sodium is definitely more detectable than the trace that may be left by potassium. Moreover, there are serious negative side effects with drinking excess sodium in the water supply.

The risk can be avoided by using potassium chloride which releases potassium ions that are good for human, and even plant, health.

The use of potassium over sodium chloride is also better for the environment as brine discharge will have less impact on waterways. Potassium being a nutrient people often do not get enough of, it may even be helpful!

Why do I need to soften my water?

Hard water affects your health as well as the “health” of your water appliances. It can even raise the price of the water you use by as much as two or three times. Irritation can result when it comes in contact with sensitive skin.

It is certainly not something you’d want to be drinking. By eliminating or reducing the number of hard mineral ions that get into the water supply, these problems can be reduced.

Conclusion

Before we wrap up, let me reiterate why some water softener salts are just simply the best.

The Diamond Crystal Water Softener made from pure potassium chloride is truly a complete package. Not only does it soften your water by getting rid of hard mineral ions. It also improves the taste of your water and provides nutritional benefits for your body and any plants you might be caring for.

Without any additives required, it helps to prolong the life of your appliances and prevents build-up. In fact, the only real complaint anyone can have about it is the bagging!

If you’re looking for something more affordable at the moment, Morton Salt Clean-Protect is the best sodium chloride water softener you could come across.

It works wonders in reducing the hardness of your water while keeping your sof-tener working smoothly. It also works with virtually all water softener systems. What’s not to want?
