Salt-Free water softeners are quickly becoming one of the most popular water softening solutions to date. There is a multitude of reasons why they are so popular and as this technology evolves, you will see advancements that make them even more effective than they currently are.

Best salt free water softener

The unique thing about the best saltless water softeners is that they are completely maintenance-free and do not require any electricity. These things are ultra-appealing to consumers when compared to salt-based systems because there is no need to add salt every few months and there is no need to discharge water with no salt water softener.

As salt-free technology has evolved, more and more systems are coming into the market and it can be daunting to choose the best salt-free water softener for you. Throughout this guide, we will tell you all about our favorite systems and answer some questions in our buying guide that will help you choose the perfect system for you.

In terms of performance, the SpringWell system is one of the highest-rated salt-free systems on the market for a reason.

The included pre-filter does a great job with water supplies that are high in sediment like sand, gravel, and other larger contaminants.

As water is brought into the system after the pre-filter, the softening system will condition the water to “break-up” hard water particles, which means that these hard water particles cannot attach to anything like pipes or faucets. The steep decline in scale build-up is worth the price of this unit; it virtually removes all of it!

What We Like:

While the instructions are not the best in the business, the installation process is simple because there are so few parts to this system.

In terms of water softeners that do not rely on salt, the Aquasana has some of the best water testing results that we have seen.

Most notably, chlorine is completely removed from your water supply, which is a tough contaminant to kill. We were also very impressed with the flow rate of all the faucets throughout the house.

This is one of the biggest complaints that we get, is the reduction in water pressure after installing any water softening or filtration system.

One of the biggest complaints we get with salt-based water systems is the additional sodium that homeowners experience in their water supply. While some sodium is good for you and your drinking water, there is a point where you do not need any more sodium in your water.

The APEC salt-free water softener does not only avoid salt pellets altogether; it does a wonderful job of disrupting sodium and other chemicals that may sneak their way into your water supply.

The APEC system is not only easy to install, but the company is also a joy to work with. They do a great job of providing environmentally conscious water solutions to not only their salt-free softeners but all their products.

Do Salt-Free Water Softeners Actually Work?

The evolution of the salt-free water softener has made it easier and easier to rely on a salt-free system for all your water softening needs. While it is true that there are several aspects of the salt-free system that are not as effective as the traditional salt-style water softener, they can be relied upon if you are looking to ensure that your water stays healthy.

Salt-free water softeners work entirely differently than their counterparts. The salt-free water softener does not necessarily remove the water hardness particles rather conditions the water not to be able to bind to surfaces.

One of the biggest issues you will see with hard water is the scale buildup on appliances and in your water pipes. Salt-free water softeners will not remove these hardening particles from the water, but they will rather convert them to a hardness crystal that cannot bind to surfaces like water pipes and showerheads.

Overall, the salt-free water softener works if you are looking to improve the longevity of your pipes and appliances. It also does condition water so that minerals are still in the water supply but by not binding, it is better for ingestion. You will not notice a drop in grains or TDS counts with a salt-free system, but overall, it does have positive effects on your water supply.

Salt Based Water Softeners vs. Salt less Water Softeners

Since the salt-free water softener became available, this has been a hot-button question in the water filtering community. There are many advantages of the tried and true salt-based water softener system but do not sleep on the salt-free water softener option; it has excellent benefits as well.

Saltless Water Softener


Saltless water softeners are most known for being entirely maintenance-free. Compared to the systems that rely on salt, they are much more user-friendly.

Gone are the days when you need to constantly check your salt tank, realize you are running low, and then head to the hardware store and spend big money on salt. Because the hardening particles are not being removed by salt, there is no need to discharge any water with these systems either. You will not waste any energy or water with a salt-free water softener, which is a big draw for many people.

No Electricity Needed

Because the salt-free system does not require an ionization process like the salt-based water softener, there is no electricity required to run these systems. This is great because you are not only saving money on the electric bill, but you are also conditioning your water naturally so you will waste any unnecessary energy.

Salt Water Softener System

“Cleaner” Water

If you are dealing with a municipal water supply that is high in contaminants such as lead, chlorine, or other heavy metals, the salt-based system will be the best solution to combat this.

The salt envelops water contaminants as water is brought through the system and removes these contaminants while allowing the clean water to make its way through. You will also notice that the water will produce more suds and bubbles in the shower and will help keep your skin moist and free of dryness.

Appliance Longevity

Salt-based water softeners are extremely popular for their ability to help appliances and faucets stay clean from scale build-up. Chlorine and other insoluble contaminants can leave sticky mildew and residue in your water delivery system, and the best way to combat this is with a solid water filtration system, like a salt-based water softener.

By keeping pipes and faucets clean of scale build-up, your appliances will last much longer than without a softening system.

Types of Salt-free Water Softener

Salt-Free Water Softeners

There are multiple different options to choose from when deciding on the best nonsalt water softener for you. It is important to remember that salt-free water softeners are an option that allows for water to be conditioned to reduce lime-scale and other build-ups.

Therefore, salt-free water softeners are often combined into other water filtration styles that allow you to choose the best solution for you. These things include multi-stage filtering options and electronic water descalers that are considered to be salt-free water softeners.

Salt-Free Water Softeners and Filtering Combinations

There are several water softening solutions available that allow you to combine the salt-free water softening descaling qualities with water filtration that will remove contaminants in your water.

This is a very good solution if you are short on space or wish to improve the water quality outside of the re-ionization process that the salt-free water softener will accomplish. These systems will combine the ionization process with several filters that do a better job of removing solids and other heavy metals.

Electronic Descaling Options

In addition to all the other water softening options available, another solution that works well as salt-free water softening option is the electromagnetic water softener. These systems are attached to the water pipe.

As water flows through, they provide a jolt of re-ionization that breaks up water molecules into smaller parts, so that contaminants will be removed from the water molecule. Because the electrical destabilizes the ions, the minerals do not have anything they can attach to. These help a ton with reducing limescale buildup among your appliances and pipes.

Advantages and disadvantages of  No salt water softener


There are several advantages one can gain from installing a salt-free water softener, otherwise known as a descaler.

The system is proven to be effective at removing scale from your water and helping elongate the life of your appliances. Most importantly, the water heater. Water heaters are expensive and if you are running untreated water through there consistently, you are leaving yourself open to issues with erosion and water pipe scale build-up.

Because a salt-free water softener conditions the water at a molecular level, a simple descaling device will help save your appliances from an early visit by the plumber.

The other thing to remember is that salt-free water softeners are entirely maintenance-free. They do not require the lugging around of salt bags and the constant refilling either. Simply install and if your saltfree system includes a filter or two, make sure those are clean and replaced and that is it!

Disadvantages of No-salt water softeners

In terms of disadvantages, there are some things that you may need to consider before installing a salt-free water softener.

For starters, the descaling properties of the salt-free system only work with water that is running. The tiny amount of energy that is produced from the running water is required for the descaling to take place.

The ions within the water need to be moving in order for them to be re-ionized and therefore, this water softening solution will only work on running water. Additionally, there are some limitations to the water hardness that salt-free systems can handle.

Most systems will not be effective if your groundwater exceeds 75 grains per gallon. If this is the case, you will need a more sophisticated solution or a combination of a salt-free system and a pre-filter system.

Are salt-free water softeners effective?

Depending on your expectations, the best nonsalt water softener can be highly effective. They are best at removing limescale build-up from your pipes and appliances, but it is important to remember that this water softening solution does not technically remove contaminants. It conditions the water at a molecular to be safer for consumption.

What are the most trusted salt-free softener brands?

We review a lot of water softening systems and have a great insight into the best brands. When it comes to salt-free water softeners, we highlighted plenty of brands in our reviews earlier on in the article. Pelican seems to be one of the most popular, and it has great reviews by nearly all users. We also really liked installing the OneFlow system; it is simple, affordable, and highly effective.

Do salt-free water softeners remove iron?

Technically, no it does not remove anything from the water on its own, but with a solid filtration combination system, it will remove iron and other contaminants.
With a salt-free water softener, it will still be healthy for consumption, but the contaminants will still be there in theory. The re-ionization process will disrupt the molecular structure, but it will technically not remove it.

Are salt-free water softeners healthy?

Overall, they are healthy. The water you consume from a salt-free water softener will be healthy to consume and healthier for your hair, skin, and nails. There are other ways to improve the water to be even healthier with a combination of salt-free conditioning and water filters.

How much does a salt-free water softener cost?

This will depend on how sophisticated the system you choose is. There will be more a higher cost associated with systems that have more features, but on average, a salt-free water softener will cost anywhere from $400 upwards to over $1500 for the top-of-the-line system.


Salt-free water softeners are an overall excellent solution to help elongate the life of your appliances and improve the overall quality of your water.

When choosing the best non-salt water softener for you, there are several factors that you should consider, including the quality of your raw water and what you hope to achieve out of your new system.

The total dissolved solids (TDS) and grains per gallon of your water supply will greatly affect which system you should go with.

However, we are confident that the information provided to you in this article will help you find the perfect salt free system for you.

Between our in-depth reviews and the information outlined in the buying guide, all the information you to choose the best saltless water softener system is right here. We thank you for tuning into this article and wish you the best of luck in your search for the perfect saltless water softener.
