Water hardness is a huge problem all over the world. Most of the time, we talk about water softeners that use salt to remove the hardness. These kinds of softeners are not suitable for people with heart or kidney disorders. Because additional salt increases the salt level in the diet. For these people, there are effective water softeners without using sodium chloride or potassium chloride. Let’s learn about the suitable and best salt-free water softener for you in this article.
Our Top Picks
Want to make a choice in minutes?
There are many variations when we talk about water softeners that don’t use salt, yet they work best. Some water softeners use cartridge to remove the hard substances from water. There are electric descalers that produce electromagnetic waves to make the hard particles insoluble materials.
If you want something that can work without electricity, there are magnetic softeners too, which can also do the job. Let’s find out which type of saltless water softener will suit you best. For this, don’t forget to read till the end…

Types of Water Softeners
There are different types of water softeners, both salt-based and salt-free. It is important to understand what each type is and how it works, to make an informed decision on which is the best for you. We’ve summarised each of the main types below:
Salt-based softeners
These are the traditional and most frequently chosen type of softener and as the name suggests, they are the opposite of salt-free softeners because they use salt. These water softening systems rely on ion exchange to replace calcium and magnesium minerals with sodium ions, lowering hard water levels.
This process occurs when water flows into a water tank that has resin beads inside, that attract hard minerals. Once the resin tank has built up enough of those hard water minerals, it has to flush all of them out and do a process called regeneration. This is why they are so popular because they are a good choice for those wanting to stop hard water affecting their plumbing and appliances. However, it is important to note that they require more maintenance than a salt-free system and will add sodium to your water.
Salt-free softeners
Salt-free systems are often called water descalers or salt-free water conditioners as they don’t work in the same way as a salt-based water softening system. They don’t replace the ions of calcium and magnesium but alter these minerals so that they don’t attach to surfaces on pipes and appliances.
At a technical level, it fights against hard water using a process called template-assisted crystallization (TAC), using magnets or cartridges to realign ions and stopping them from attaching to surfaces. Salt-free softeners are a fantastic choice for reducing scale on appliances, require almost no maintenance and are relatively simple to install and use.
Dual-tank softeners
An alternative water softening system is dual-tank softeners, designed for larger properties that have a high level of water usage. The fundamental difference with this type of water softening system is that they have two large tanks, one of which is always a brine tank. Whilst one system is working, the other is regenerating and as a result, you will have a continuous supply of soft water.
It is important to note that these systems will often use salt-based water softening systems, as opposed to a salt-free system and may also have a water filtration part to it as well.
How do salt-free systems work?
Salt-free systems will generally follow the same process, which is very different from the traditional salt-based water softeners. At the heart of the difference, is the fact that they don’t remove hard minerals such as calcium and magnesium, but they alter them into a new form that stops them attaching to pipes and appliance surfaces.
Salt-free water conditioners use TAC for this mineral transformation, whereby it catches hard minerals gradually building up micro-crystals which break off back into the water once they get to a certain size. As this new form is stable, they are far less likely to change shape or attach to surfaces.
It is important to note that whilst this salt-free process is highly effective, it doesn’t actually remove the minerals. However, if you want a maintenance-free, cost-effective way to tackle hard water, then a salt-free system is a fantastic option.
Key factors to consider
There are some key factors and features to think about when choosing which saltless water softener is best for your household. We’ve summarised them below:
Capacity
This is the volume of water that your chosen water softening system can cope with, in a given hour or day. It is so important to think about this because the number one complaint and frustration is when a water softener or water filter is unable to produce enough water for a household, especially busy or larger ones.
To fully assess what the right capacity you need, it is also important to know where on the hard water scale your water supply lies in your area, as the harder it is then the more effort required to process the water. This is true whether you have a city water supply or from a well.
Once you have your usage and hardness data, you can work out the most efficient system and it doesn’t always mean buying the biggest possible as this may well be a waste of money. A whole house salt-free softener is a fantastic system but you may only need a smaller device for specific faucets.
Water Flow Rate and Water Pressure
Any kind of water conditioner, water filter or water treatment will have an impact on the water flow rate because they are processing the water before it reaches you. As a result, it is important to consider whether you have any issues with your water supplies flow rate and what the manufacturer of the salt-free water softening system says about its water systems performance.
The same can be said about water pressure and water quality, as the worse these are then the harder the water systems will have to work.
Installation
Luckily, most salt-free water softeners are very easy to install requiring minimal expertise to do so. This means you don’t need to spend money on a professional plumber helping you, driving down the cost of getting a new water softener system. If you have a well water supply or an existing water filtration system, it is important to make sure you can install your new salt-free water softening system in the right place.
Lifespan
When buying a new saltless water softener or any kind of water filtration system, you want to know how long it will last and how long it will perform at the rate expected. You don’t want to end up having to replace parts or the entire system regularly, otherwise, it starts to become an inconvenience and added expense. This means that is isn’t always the best idea to go for the cheapest option but look at performance levels and customer reviews to choose one that delivers what you need.
The Pros and Cons of a salt-free system
There are some fantastic benefits to choosing a salt-free water softening system for your household but it is also important to understand potential limitations. This way, you can make an informed decision about whether salt-free softeners are the way to go, or a traditional salt-based water softener system is better for you.
Pros
There are some fantastic benefits to choosing one of the best salt-free water softeners for your household including:
No added salt
As the name suggests, because these are salt-free systems, then you are not adding salt to the process and this is a fantastic health benefit. Many people are concerned about what they put in their body and there are also those who have a medical condition that means they should have much sodium in their diet.
Maintenance-free
There is almost no maintenance required with a salt-free system once you have installed it, which is easy enough in most cases. They don’t require additional parts or have the need for salt or chemicals to be replenished when they run low. This means you can pretty much just set up the salt-free system and forget about it, except for the odd check to make sure the process of water softening is still happening as expected.
No residue
As a result of the scientific process that salt-free softeners undertake, you will no longer have to deal with hard water leaving white residue on surfaces like glasses and sinks. This is because a salt-free softener will change the minerals into a different form, stopping them from clinging to surfaces. Whilst this doesn’t mean it is soft water, it certainly does a great job at reducing this major complaint about hard water.
Reduces scale build up
Quite possibly one of the biggest issues that hard water causes is scale build-up in pipes, faucets and appliances. In the long term, this will cause appliances and pipes to lose performance, break and need replacing which can be an expensive result of not treating hard water properly. You may also notice a foul smell being produced from faucets when you run tap water or shower water if there is a scale build-up.
A water conditioner like the salt-free softener systems on our list help minimise this problem when they change the form of minerals, in the same way as stopping residue from happening because they can no longer attach to surfaces in pipes and faucets.
Cons
Whilst there are some fantastic reasons that make a salt-free softener a great choice for your household, it is important to be aware of potential downsides and so you should make sure you wouldn’t be affected by any of the following:
It is still hard water
The main downside of a water softening system like this is that it doesn’t change hard water to soft water. It will change the shape and design of the ions to stop them attaching to surfaces but still leaves them in the water supply. Now, this isn’t a major problem because you’re still tackling the main issue of scale build-up and residue, without adding salt to your water supply.
FAQs:
Do salt-free water softeners really work?
Salt-free water softeners really work and are better than traditional salt-based water softeners. They don’t add anything to water and also don’t remove anything from it. It reconditions the water so that it flows smoothly throughout the plumbing to the sewage system without any scale buildup.
How do salt-free water softeners work?
Salt-free water softeners use cartridge to remove hard substances from water. The electronic water softeners are also said as salt-free water softeners. They make electromagnetic waves in hard water to make hard particles insoluble in water. There are magnetic softeners too that create magnetic waves to reduce hardness in water.
Are salt-free water softeners better?
Salt-free water softeners are better for people with heart and kidney disorders. Because the additional salt that salt-based water softeners add in water is not good for their health. However, it may be that a saltless water treatment system doesn’t perform well enough for your individual requirements, so don’t necessarily discount a different type of water softener system, such as a salt-water softener.
How much does a salt-free water softener cost?
A salt-free water softener, if it is magnetic, will cost you around 50 dollars. If you choose an electronic salt-free water softener, it will cost you around 150 to 400 dollars. And if a salt-free water softener is a cartridge-based system, it will cost you around 600 dollars.
Are salt-free water softeners safe?
Salt-free water softeners are safe for health. As these water systems don’t remove healthy minerals from water and don’t add anything harmful to it. They are best for people with kidney and heart disorders. Whilst they don’t actually change the water hardness levels, they do reduce residue and scale.
How to install a salt-free water softener?
Most of the salt-free water softeners come pre-assembled. So you don’t need much plumbing experience to install it. The installation manual will be enough to help you out. If you go for an electronic or magnetic water softener, they will only need a 15 minutes job.
What is a salt-free water softener?
A salt-free water softener is a system that uses a cartridge to make hard components in water as insoluble. By that, they flow through plumbing to the sewage without causing any scale. You will only need to replace the cartridge after a specific interval with no further maintenance, making it effectively maintenance-free.
Do salt-free water softeners remove iron?
Salt-free water softeners don’t remove anything from the water. They also don’t remove iron. Rather, they make iron particles insoluble in water so that it doesn’t cause scale build. This way, the healthy iron will remain in the water and will not cause any harm.
Which salt-free water softeners are the best?
Cartridge based salt-free water softeners are best among all. And the best of such type is the Aquasana Whole House salt-free water softener. It uses the Scale Control Media (SCM) softening technology to soften water without adding sodium into it.
