If you are looking for the best water softener salt options, it means you deal with hard water. Having spotty dishes and white crusts or films on your dishwasher because of hard water can be endlessly annoying. Some households with hard water have even had to completely replace their dishwasher!
However, there’s no need to despair for much longer! A water softener can completely change the quality of your water to eliminate these problems. Of course, that brings us to the topic at hand, salt.
Water Softener Salt Uses
Water softeners, dishwashers, and shower filters all use salt to remove hardness. To maintain your water softener, periodic salt replacement is necessary.
There are a number of different replacement salts available. Our team searched all over the market, and we came up with a list of ten of the best.
Keep in mind that there are many different brands and types of salt. While some customers swear one option is the absolute best, others may proclaim their favorite is far superior, so it comes down to a matter of opinion. We’ve ranked the salts below based on the number of positive reviews they received, in order to provide a loose idea of what may work best for you. Keep reading to find out more!
Common Types of Salts
Here are the 3 types of salts that fit our options.
#1. Sea Salt
Sometimes referred to as “solar salt”, sea salt is, obviously, gathered from the sea. The gathering process involves exposing seawater to direct sunlight and wind. It then forms into a solid block of crystals.
The main advantage of sea salt is that it’s usually cheap and clean. However, quality can vary from product to product.
#2. Rock Salt
Rock salt is gathered from underground deposits that have built up over thousands of years. You can easily find it, and it’s usually cheap. Also, some manufacturers will deliver rock salt directly to your home.
However, it’s the least pure of all salt types. In most cases, it contains minerals that can cause clogs over time.
#3. Potassium Chloride
Although it’s considered a “non-salt” option, potassium chloride is actually a type of salt by definition. Some people even use it instead of table salt, if they have certain health conditions that require a specific sodium intake.
However, during filtration, potassium chloride functions more like a water conditioner than a softener. It also costs more, so you would be paying more for less performance.

Salt for Water Softeners – Buyer’s Guide
✓ Your Budget
When buying a water softener, you should first consider the hardness of your water. If it has a high amount of calcium and magnesium, you will need more salt, which directly affects your monthly maintenance costs. As well, if you have a large family, or use significant amounts of water, you may find yourself considering the cost of buying it.
However, you can offset these costs by buying in bulk or buying pure salt which is far more potent and long-lasting. As well, if you buy salt directly from the manufacturer, oftentimes they offer various discounts.
✓ Type of Water Softener
If you buy high-quality salt, you can use it in any type of unit. Types include evaporated, solar, rock, and even block. There are also softeners that use TAC media instead of salt, which works by changing the composition of certain minerals and therefore making the water soft.
✓ Saltier Water Taste
Water softeners do release sodium chloride into the water in small quantities, leading to a faint salty taste. It’s usually not noticeable, but if you don’t like the taste, consider buying Potassium Chloride instead. It softens water without affecting the taste, however, it costs around three times more than a normal slat.
You should regularly check and top off your softener to keep the device efficient. Some types may cause “bridges” in your tank; which require manual removal by breaking the bridge and letting the water absorb the pieces.
What Amount of Salt do You Need?
This mainly depends mainly on two factors: the amount of water you use daily and how hard the water is. A four-person family with hard water of 8-10 GPG would use around 8 to 10 lbs each week, or a 40-lb bag each month. This is just an estimation, and if your water is harder, or has a significant iron content, you may need more every month.
If you are concerned about being environmentally friendly, we suggest using potassium-based salts to avoid passing excessive sodium into your wastewater. Also, plants need potassium, and so run-off from water treated with potassium-based salts is far more beneficial for them, compared to sodium-based.
Do Water Softeners Require Salt?
To keep a water softener working properly, it will need frequent salt refills. The size of the tank and the hardness of your water directly determine how often it will need to be refilled.
No matter what type of unit you use, it’s advised to regularly check for the following three things.
1. Salt Levels are Visibly Low
This is the most obvious sign that your water softener needs more salt. You just need to remove the lid and take a look inside. If the tank is less than half full, you should add more. If your levels fall beneath 25%, the device begins to lose efficiency.
2. Device Age
The fact is that the age of your softener plays a role in how much salt is needed. Older devices use more, whereas newer models are much more efficient, and use less salt to soften the same amount of water. These updated units can run up to 8 weeks on a full tank, while older models need more regular fill-ups.
3. Tank Bridges
If it seems your water softener is losing efficiency, but there is plenty in the tank, it could be that the salt has dissolved and clumped together in the tank, and created hard formations called “bridges”. This is a common issue when using cheap and low-quality salt. If you keep the device in a low-humidity area and use high-quality salt, bridges should be avoidable. Otherwise, bridges need to be removed and manually broken up into smaller pieces, before being mixed back into the tank.
There are a few great brands that make high-quality salt. Be sure to check them out when buying a new unit.
Morton is one of the most popular salt brands because they offer many products, including potassium chloride. Also, on sites such as Home Depot, Morton has excellent ratings and is known for providing excellent value for the price you pay.
✓ Diamond Crystal
Besides Morton, Diamond Crystal is another very popular manufacturer of salts. Their high-quality, efficient products match the high reputation they’ve gained. Also, they recently patented a dual-handled bag design, so you can pour with no problems.
✓ Nature’s Own
Nature’s Own is a great solution for people who prefer potassium chloride, but as we mentioned, it is a bit pricier than other options.
✓ Windsor Salt
If you want to shop on a budget, you should check out Windsor Salt. They sell at a decent price.
How To Add Salt
Water softeners revitalize automatically, but if you need more salt, you’ll have to add it manually. So, let’s see how to do it.
First, remove the lid and take note of any buildup on the walls. Remove the buildup completely, using a wet cloth. Then, it’s time to add the salt.
Although this step depends on the tank size, you usually need to add two 40-lb bags, which will fill the tank to half full.
Once done, manually regenerate the device. This process can differ between models. There should be a regenerate button somewhere on the control panel, which you can press and hold until the regeneration cycle starts.
- If the water contains iron, it might damage the resin bed. In that case, you should buy an Iron-Out material to clean the system.
- The tank needs to be cleaned regularly, once a year.
- Don’t forget that the outlet pipe should always be above the grate. Otherwise, it could completely destroy the system and void the warranty.
Frequently Asked Questions
What Is the Best Type of Salt to Use for a Water Softener?
We recommend you use high-purity salts and pellets for water softeners. The Diamond Crystal Bright & Soft water softener pellets or the Morton F124700000g Clean & Protect water softener salt are very good options. Make sure you read your softener’s manual and follow the instructions.
Does It Matter What Brand of Salt You Use In a Water Softener?
Yes, because many generic brands sold at home improvement stores or supermarkets contain high levels of water-insoluble elements or impurities.
Are Salt Pellets or Crystals for Water Softeners Better?
It all depends on the water softener/dishwasher you use, however, salt pellets can help with the reduction of bridging. They work well with all-in-one softener systems tanks and are efficient for most homes.
How Long Does a Water Softener Last?
This depends upon several factors. For example, new, high-efficiency devices usually last longer than ones with standard old technology. Also, the quality of your water can directly affect lifespan. With moderately hard water and regular maintenance, a good, high-quality device can last up to 20 years.
Can You Put Any Salt in the Softener?
People often wonder if it’s fine to use table salt for the water softener, but this is something you should never do. Table salt has much smaller crystals, which can cause troubles inside the brine tank.
Does Softening Salt Contain Chemicals?
Some may contain additives that prevent hardening. Fortunately, even if it does contain additives or impurities, but it doesn’t affect the water quality.
Can You Mix Different Salts Together?
It won’t damage the softener, but you probably shouldn’t. Not everyone is good for every type of water, so when you find the best product for your needs, it may not be ideal to mix it with other salts.
How Often to Add Salt to the Softener?
You should refill the tank at least once per month as part of a routine tank check. Also, refill any time you notice a drop in your device’s performance due to an empty tank.
We’ve presented the 10 best softener salts above, with the Miele Care salt being the best. All of these salts are amazing, even the ones in the last places on the list. Choosing one is a just matter of personal preference. However, one thing is for sure – having some type of water softener is far better than having none at all. Good luck in choosing the one that’s best for you.
