It would be a mistake to think that buying water softener salt is as easy as picking a culinary version from a grocery store’s condiment and seasoning section. First-time water softener owners often find choosing a suitable product challenging, especially if they fail to consider the following factors.

  • Water Softener Compatibility: Your first consideration should be the salt’s compatibility with your water softener. Most water softener brands have specific recommendations on what salt products to use, while others are more lenient. These companies allow homeowners to choose any water softener salt brand.
  • Form: Water softener salts come in evaporated pellets, solar crystals, salt blocks, and rock salt. Although pricey, evaporated salt pellets and salt blocks have the highest sodium chloride purity. Meanwhile, rock salts are perfect for budget-conscious families, while solar crystals are suitable for ecologically-minded households with moderately hard water.
  • Formulation: Although all water softener salts contain sodium chloride for removing calcium and magnesium in the water, some products have special formulations. For example, a water softener salt might have anticaking agents to prevent the formation of lumps in the brine tank. Others might feature a unique additive that reduces rust stains on tubs, sinks, showerheads, and other water fixtures.

But with a buying guide like below, you can better compare the features, pros and cons of each product. Knowing what to expect, you’ll also be able to consider your choices closely and pick one that matches your needs. Let’s get started with the following reviews.

What Is Water Softener Salt/ Who Is This For


A water softener salt, like a Morton softener salt, is usually composed of sodium chloride or NaCl and is almost similar to the typical salt used in cooking.

Softener salt is added to your water softener to remove the minerals in water that makes it hard. Hard water has high levels of calcium and magnesium minerals. These minerals contribute to the limescale buildup and cause your plumbing system and water fixtures to deteriorate more quicker.

Just as what you might have read on Reddit forums, there are also theories that the high mineral water content of hard water can contribute to health problems, but these are not yet proven.

Water catalyst salt is used to remove the water’s hardness so an ion exchange can occur. Hard water mineral deposits are eliminated when the water goes through the resin beads of the softener tank.

The water softening salt is utilized to recharge and renew the resin beads periodically. This is necessary so that it can carry on removing these minerals.

Water softening salt is for households or even organizations who want to soften their hard water. This is an affordable option, and salt is always available for purchase. It is one of the easiest ways to turn your hard water into soft water.

How Do Water Softeners Salts Work

Having a good background in how water softeners work can make understanding the process easier, especially if you add salt to the equation.

Most of today’s water softeners are founded on ion exchange. This means that the hardness ions which turn water into hard water are exchanged for another ion. In this case, it will be exchanged for salt ions since it is the primary catalyst in the process.

Unlike incorporating water purification tablets which kill and destroy all the unwanted elements in your water, an ion exchange will swap ions, leading to softening of the hard water.

The process of ion exchange using water softener salts happens in the softener’s resin tank. As the water goes and flows through the tank, it will contact resin beads protected in salt ions. When the water flows and makes contact with the resin beads, the hardness ions will switch places with the salt resin beads, making the water soft.

With the non-stop contact of the hard water, the salt resin beads would gradually lose their capacity to switch any hardness ion, but this can be remedied by recharging the resin beads. You do this by adding more salt bags, pellets, crystals, or tablets. When restored, they can continue with the ion swap and produce enough soft water to sustain your entire household.

What Are The Different Types Of Water Softener Salt


Aside from water softener salt price comparison, you might also want to know the different types of these products on the market. It is surprising to know that there are different kinds of water softening salt that you can use in your water softener. Each of the types has its advantages and disadvantages, so you have to identify your need before choosing the top-quality type to use.

Here are the different types of water softener salts:

Rock Salt – as the name implies, this salt looks like small rocks and pebbles. This is considered the most economical among all types of water softener salts, but unfortunately, it is the least favored. The calcium sulfate of rock salt is very high, so it doesn’t dissolve very well in water. It can also leave a generous amount of residue.

Sea Salt – also referred to as solar salt because of the process of manufacturing that it goes through. This kind of salt is mined from the sea and, when processed, is more soluble than your rock salt. It is also budget-friendly and can be widely procured. A drawback of this kind of salt is that its efficiency is not so reliable, especially if your water hardness level is exceptionally high.

Block Salt – this is literally what the name suggests, a block of salt. This is not recommended to use with your water softener unless expressly advised by your expert plumber. When instructed to use this salt, your brine’s water level should be made higher because the blocks need to be fully submerged.

Evaporated Salt – this type is the purest of all salt types and is also the most expensive of them all. Salt with higher purity is the best kind of water softener because it is very soluble. It also decreases the risk of bridging, mushing, or buildup that can further cause clogging.

Potassium Chloride – although colloquially this is referred to as a ‘non-salt’ alternative, it is still a type of salt. It is 99.9% sodium-free, making it the ideal salt for households with members who need to reduce sodium consumption due to health concerns.

Advantages And Disadvantages Of Using Water Softener Salt

You can use other catalysts for your soft water, but salts, like do it best water softener salt, are always the top choice both among long-time users and folks who are just checking if they will work for them.

Using salt as your ion exchange agent comes with many advantages, but like all products, it is not perfect, and there are also some drawbacks. Here are just some of the perks of using salt:

Very affordable – our water softener is useless without a compound that can soften the water, and fortunately, salt doesn’t cost that much. You can easily stock up on your salt sacks to last you for months and even a whole year. You won’t need to abruptly stop getting soft water just because you can’t afford your catalyst. Salt is sweet on the budget.

Easy procurement – you can buy salt almost everywhere. So, it being out of stock is not going to happen. You can drive to Home Depot and go home with bags of salt. You can order online, and you’ll have the salt delivered to you. It is just so accessible that it makes having soft water easier.

Better water quality – this is the ultimate goal anyway, and water softener salts deliver just that. A water softener salt for rust is an effective way to make your water ‘cleaner’ and taste better. It makes your laundry retain its bright colors. You’ll see reduced mineral buildup on your sink, faucets, and plumbing system.

One drawback of using water softener salt, such as water softener salt for sensitive skin, is that it can affect the taste of your water. This is especially true for folks with discerning palates. Aside from this, it would help if you were vigilant in doing your maintenance routine so you can address any bridging in your tank. You need to be wary of the amount of salt you put in as well because it can affect the system’s efficiency.

Buying Guide


Sure, you already have a top of the line water softener, but this doesn’t mean that you’d automatically use salt as your catalyst. It pays a lot to get to know your current investments, and it is even more beneficial if you also invest time and effort when shopping for your water softener salt. Here are some things you need to consider when buying your water softener salt.

Before buying tons and tons of salt, make sure that your water softener is salt-based and not a salt-free water softener. Don’t make the mistake of procuring tens and hundreds of salt bags just because you have a water softener. This is a common problem for many.

Price – quite surprisingly, there are so many kinds of salt you can use for your water softener. The reality is, most will go for the lowest price or purchase whatever type of salt that they can get their hands on without really pausing to look into labels.

The goal might be to save some dollars by going for the least expensive ones but consider the possibility of having to spend more because of low-quality salt that would mean more maintenance for your actual water softener. Go through the content, look it up, and always get the salt that gives you top-tier value for your money.

Performance – this is a huge consideration if you have more extensive water softening systems. You have to make sure that your salt is effective in softening your water. So far, the most suitable option for a whole house type of water softener will be evaporated salt for water softener.

Health – a critical consideration because you have to make sure that members of your family won’t have any adverse health reactions to salt. You might think that it is just a small grain of salt but consider household members who have kidney stones and have sodium issues.

Sure, you can still use salt but opt for potassium chloride. But if it is blood pressure that you are keeping an eye on, don’t risk using potassium chloride. Consider everyone who would be using or drinking your water that is softened by salt.

Maintenance – you have to include in your calendar timings for salt refilling and regeneration. Are these tasks something that you can continually accomplish? Note that water softeners using salt would need to be regularly checked to keep an eye on salt mush and humidity.

Frequently Asked Questions (FAQs)

Can you mix different brands of water softener salt?

No, you should not mix different hardness minerals and rust-removing water softener salt brands. Some products might have more impurities than others, which makes the softener more prone to clogging.

A water softener brand might have a specific recommendation to optimize its products’ performance. For example, the K-Life sodium-free crystals are perfect for Culligan water softeners, especially the brand’s potassium water softener series.

Meanwhile, the Diamond Crystal Bright and Soft salt pellets are suitable for Kinetico systems. These products might not be the cheapest, but Kinetico considers them the best for its water softeners because they are 100% soluble and do not leave salt residues.

On the other hand, you can use almost any salt for RainSoft water softener systems, provided they are potassium chloride or sodium chloride.

It is worth noting that water softeners vary in design. Some use pellets, while others use crystals. Still, some brands use block salt. It should be okay to mix different brands as long as they have the same salt form (i.e., pellet for pellet or crystal for crystal).

Salt crystals are ideal for low-salt screens and all-in-one water softeners. Pellets and salt blocks are perfect for single-tank softeners.

How often should you add salt to water softeners?

Manufacturers have different recommendations on the frequency of adding salt to water softeners, although the average suggestion is once a month. Water consumption and hardness levels also impact salt addition frequency.

For example, a 40-pound dishwasher salt is sufficient for a four-member household with moderate water hardness for a month. Meanwhile, a six-member family with very hard water might find the salt amount insufficient, lasting only two to three weeks.

You might want to check the manufacturer’s guidelines on how much natural salt you must add to the water softener a month. For instance, the brand might suggest using a 50-pound bag of salt for septic systems per month. On the first day of the second month, assess your brine tank to evaluate your salt usage. You can adjust it from there.

Note that the brine tank should be at least 25% full of salt. You can add more salt until the level reaches four to six inches from the brine tank’s top.

Does it matter what salt you use in the water softener?

Yes, the difference salt for softener system products has over ordinary salts (i.e., table salt) is like night and day. These salts dislodge calcium, magnesium, and other minerals in the water, not for imparting flavor.

Water softener salts vary in form. Evaporated salt pellets have the highest sodium chloride purity, making them the most suitable solution for households with very hard water. People buying softeners for hair and skin health should consider this option, as it can reduce unpleasant residues and contaminants.

Pros pick solar salt because of its eco-friendliness while maintaining exceptional water softening capabilities for moderately hard water. Rock salt is budget-conscious households’ choice, while block salt is ideal for resisting brine tank mushing and bridging.

Brands can have water softener salts in different forms. For example, Morton Clean and Protect vs Pure and Natural pits evaporated salt pellets against natural solar salt crystals. Morton Waves vs pellets underscores the brand’s block salt formulation.

It is the same case with Diamond Crystal. In the Bright and Soft vs Solar Naturals debate, it is easy to determine that the former is an evaporated salt pellet while the latter is a solar variant. That also addresses the blue vs yellow water softener salt conundrum, with blue being solar and yellow being an evaporated variant.

Does softening salt contain chemicals?

Water softener salts should contain only sodium chloride or potassium chloride as an alternative. However, most products do not undergo comprehensive processing. Hence, they may have dirt and other particles we do not know.

Some brands might add stabilizers, anticaking agents, and other chemicals to the water softener salt. You can bring a sample to a laboratory if you are doubtful about your water softener salt’s chemical composition.

What are the most trusted water softener salt brands?

Today, there are many businesses — big and small that manufacture and provide salt for water softeners. With so many commitments and expectations of reliability and softer water, it can be a little daunting to be loyal to a brand.

If you want quality, functionality, and reliability, explore these brands. They are the most trusted water softener salt brands on the market today. Read their reviews too for unbiased feedback.

Diamond crystal vs Morton water softener salt: Which one is better?

Water softener salt pellets or crystals? As far as type is concerned, there are water softener salt brands that are considered the best. Among the many available water softener salts, Diamond Crystal and Morton are the top favorites.

Morton is one of the most trusted brands when it comes to water softening salt products. It has many varieties, including potassium chloride and evaporated salt pellets with patented and unique formulas that reduce scale buildup.

The brand’s crystals are guaranteed to extend the longevity of your plumbing system and your appliances because it decreases the buildup of your sinks and showers.

Is one brand better than the other? Most would say Morton is the better option but with either, you can be sure of high-quality salts and water that is softer and more usable.

Are salt pellets or crystals better?

The salt that you use for your water softener impacts its efficiency. There is a choice between using softener crystals and pellets. Both have their advantages, and knowing which one to use can yield you better results.

Softener crystals are 9.6% solar-made sodium chloride. It is produced by the salt going through the process of solar evaporation. Softener crystals look like white abrasive gems. These are highly recommended for homes with low water consumption or those who are using a 2-part water softening device.

Crystals being used in households with high water consumption may lead to bridging problems within your brine tank.

Salt pellets, meanwhile, reduce salt bridges and are designed to work with households with high water consumption and those all-in-one tank systems.

Some salt pellets have citric acid, a cleaning agent, in their component, which serves as an additional layer of protection for your plumbing system and appliances.

Is crystal better than pellets? It depends entirely on your current set-up and water softener. Crystals are for homes who only use water minimally, while the pellets are for families with moderate to high water use that frequently makes their plumbing system work.

Can I use pool salt in my water softener?

Technically you can use pool salt in your water softener, but it is not advisable. Water softeners are recommended to work with a coarser type of salt so they can be more efficient.

Pool salt is more refined than the regular salts intended for water softeners, so as a result, it will not permit the water to flow through as quickly as desired.

Additionally, using pool salt can make your water taste very salty. This is because pool salt can prevent the brine from coming out of the tank. As a result, that brine will be in your water.

How to use it?

Now that you have an overview of how salt becomes vital in a water softener system and the different types of salt that you can consider, we’ll talk about usage.

The process is straightforward. No complications, just some minor details that you need to look into.

Once the salt is ready, open your tank’s lid and check the status of the tank. Keep an eye on any sediment, salt deposits, buildups, or anything that is off.

You also have to double-check the salt level. By checking this, you will know if the amount of salt you are putting in is correct. At the same time, it will help determine if your water softener is efficiently using the salt that you are adding.

If all is well, you can pour the recommended amount of salt into your tank and securely close the tank’s cover.

How to care and store?

Your water softener salt should always be kept dry, and its package tightly sealed to prevent humidity and moisture from getting into it.

It is top-tier to store it in airtight containers that can protect it from dust, dirt, and moisture. At the same time, keeping them in secured storage can also keep your kids from playing with them and your pet animals from having a salt attack.

It’s good to stock up on salts like Morton water softener salt but not too much, especially if you don’t have space to store them. It is highly recommended to keep your salt supply in a dry and dark location.

Once you open up salt sacks, always ensure that you tightly secure the opening to avoid any clumping. Should airtight containers not be readily available, you can store them in the bags they are initially packaged in, but you must regularly check for any damage and holes.

Where to buy?

The most trusted place to buy water softener salt depends on your preference. You can easily buy from your local hardware store and grocery stores. Most gasoline stations also carry these among their merchandise.

If you have a particular preference for a brand, you can directly go to its retail outlet if it has one near you or order from its website. You also can buy from water conditioner servicing businesses since they usually carry such products while doing routine maintenance jobs.
