This is our review of the best salt free water softener for 2022.

If you want to eliminate water hardness problems without the use of chemicals or minerals, salt free water softener is the way to go.

Salt-free softeners are not actually softeners in the sense of the word, but conditioners that remove scale. In addition, they preserve essential minerals that are healthy for human consumption. They are eco-friendly, long-lasting, and low-maintenance for homeowners.

After evaluating numerous water systems, we determined the best salt free water softener to be the Springwell FutureSoft, a highly efficient system that will remove hardness from your water.

Criteria For Choosing a Saltless Water Softener System

First, understand the differences between salt-based and salt free water softening system, and decide which is best for you and your household.

Research widely and understand each product before purchasing it. Reading reviews is also a great way to understand if the water softening system will work for you. If you decide that a salt-less softener is for you, then check out these considerations.

Softener Size:

Start by doing some math. Calculate your household size and how much water you use daily. To put it into perspective, the average person uses 80 to 100 gallons a day, but of course, that number varies depending on your lifestyle.

To decide on the size of your softener, you will need to figure out the grain rating of your current water. If you have city water, you can call the municipal and ask how many grains per gallon they allow to pass through the water treatment system. You can also test your water yourself with a water testing kit. On average, most cities allow 15 grains per gallon, while well water may contain up to 40 grains per gallon.

Even though salt-free softeners do not flush water like salt-based ones, they usually use the grain rating to indicate how long their product will last and how effective it is at softening hard water. A higher grain capacity means your softener will be more energy efficient.

Water Flow Rate:

Some water filters and softeners will drop your water’s flow rate, while others will not. A low flow rate simply means less water pressure, and this could be troublesome if you have several people in your household using water at the same time.

To put this into perspective, a person living alone typically needs a four-gallon per minute (GPM) flow rate. For anyone else living in the household, add 1-2 gallons, and then estimate your flow rate. For example, a family of four would need a flow rate of 7-10 GPM.


Obviously, you won’t want to buy a new softener every year, so look for one that lasts. Look for ones that are built well and provide warranties. For example, our third selection, the Aquasana Whole House Filter with Salt-Free Conditioner, boasts a ten-year warranty!

Also, if you want to install your softener outside, look for ones that can be safely installed in the outdoors. No softener can work well in freezing temperatures, but there are some, like the SoftPro Elite, that can be installed outdoors.


Most salt-less softeners offer optional upgrades such as UV filtration media. Think about whether you would like additional services through pairing these products with your water softener. Some products, like the Aquasana Whole House Filter with Salt-Free Conditioner, are water filters with softener properties. If you need a filter in addition to a softener, consider looking for combos like this one.

Installation and Maintenance:

Generally, salt free water softeners entail straightforward installation. They are compact and simple and ready to attach to your water lines. However, you could consider optional kits to make the process simpler or hire a technician if you don’t want to install it yourself. Since no salts are needed, the only maintenance required is replacing the filter.


Cost will more than likely factor into your decision. You don’t have to pay a fortune for a quality salt-less softener. For example, Quality Water Treatment’s SoftPro Elite Salt Free Softener is available at a great price, and you can make interest-free payments.

Most companies allow you to make payments, as well. Just note that you will be saving money in the long run. For one, your appliances and pipes will last longer. Secondly, you will save on your energy and water bill by using a salt-less softener versus a salt-based softener. Also, most salt-free softeners require little maintenance, so you won’t be buying filters every month.

Springwell water softener

Using proprietary media, SpringWell Water developed a unique tank design that gets rid of hardness better than other designs on the market. The FutureSoft media uses fluidization to converts the water’s hardness into calcite crystals that won’t stick to anything, even under extreme temperatures.

Installing this chemical-free, salt-free system will eliminate scale, extend the life of your pipes and appliances, all with no electricity or water waste. This system also comes in three different units depending on the number of bathrooms are in the house with 12 to 20 GPM, it won’t drop your water pressure.

The company also offers an installation kit that has all you need for a successful install, although you need to purchase it separately. The good news is, once your SpringWell FutureSoft Water Softener is installed, it may not need replacing, and all parts come with a lifetime guarantee.

SpringWell FutureSoft is top of the market in soft water systems, and it comes with a higher cost than some of its competitors. However, without using electricity or water waste and never needing replacing, it is still a cost-effective solution down the road.

Greenwave Salt-Free Water Conditioner

High Flow Rate
Greenwave Water Softener
For Large Household
US Water Systems’ Greenwave Salt-Free Water Conditioner is an ecologically friendly water softening system that, as the name implies, does not use salt in the process.

Our second choice saltless water softener is the Greenwave system which offers 97% effectiveness against hard water without the use of salt. This system is recommended for very large households in need of a salt free water softener with higher water flow rate.

It comes in 10 GPM, 15 GPM, 20 GPM, and 25 GPM versions with ¾ inch or 1-inch inlets and outlets. There is also an option to choose a radial flow carbon filter pre-treatment.

We like that instead of removing minerals that cause hard water, the Greenwave Salt-Free Water Conditioner neutralizes them, transforming them through Nucleation Assisted Crystallization (NAC). This process stops them from sticking to surfaces, eliminating the adverse effects of hard water by turning them into microscopic crystals that pass through the system.

Users we spoke to revealed that the Greenwave system is highly efficient in removing the effects of hard water. They report a noticeable difference in the way their water feels after installing this product.

While research into user feedback of the Greenwave Salt-Free Water Conditioner indicates that most users are delighted with the results of the Greenwave system, several users report that the instructional material on installation is less than stellar. A few even report having to turn to a plumber to install the system.

Users also note that the checkout process on the website is glitchy. Some had trouble paying with a credit card and had to use PayPal. Others found that the Checkout cart crashed several times before finally completing the transaction.

A few note that shipping costs were higher than expected for a product of this size.

Overall, however, most users find the Greenwave Salt-Free Water Conditioner to perform its duties satisfactorily and to be well worth the investment.

Benefits of this system:

  • Salt-free
  • 97% effective
  • No water waste
  • Uses no electricity
  • Prevents scale buildup
  • Highly effective
  • Produces no water waste
  • Does not require electricity
  • Eliminates buildup in plumbing
  • Install instructional media is not as helpful as it could be
  • The checkout process on the website is glitchy
  • Shipping costs are a bit high

Customers rave about the friendly and thorough help from this company.

Aquasana Whole House Filter System with Salt-Free Conditioner

Filter & Softener
If you’re looking for a water filtration system and softener combo, the Aquasana Whole House Filter with salt-less  Conditioner is a compelling system to check out. Also called “1 Million Gallon Rhino,” this filter will purify your house’s water while adding softening benefits with no electricity and water waste.

This filter/softener combo system utilizes a sediment pre-filter, a carbon-zinc and mineral stone filter, an activated carbon filter, a post-filter, and a salt-free conditioner to remove heavy metals, herbicides, pesticides, and other harmful pollutants from your water. You can add an optional UV filter that protects against bacteria and viruses. In addition, it meets NSF certification for removing up to 97% of chlorine. The salt-free conditioner system uses Scale Control Media (SCM) to prevent minerals from binding to form scale build-up in your pipes and appliances. The result is clean, purified water throughout your home.

This system is installed in the front of your water heater near the main water inlet in your home. You could install yourself, but to get the 1 million gallons guaranteed, you will need a qualified plumber to install it for you. The only maintenance is the replacement of filters. The sediment filter needs replaced every three months, and the other two filters will last 12 months.

The 1 Million Rhino is more expensive than some others, but it also offers more effective filtration and softeners than most. It is possible that the Aquasana Rhino will drop your home’s water pressure, as its flow rate is 7.0 GPM; however, this is a common effect of filtration systems.

Salt vs Saltless Water Softener

While it may seem that the only difference between a salt-free water softening system and a salt-based water system is the use or omission of salt, there are actually more differences to explore.

What is a salt-based softener?

Water Softener Sale

Salt-based water softeners use an electric metered valve on top of the tank to capture water. Through a process called ion exchange, these systems use flushing cycles to purge the calcium and magnesium from the water while replacing them with sodium (salt). The minerals are captured and flushed down the drain line. The salt is then replenished so the cycle can begin again.

Salt-based systems efficiently remove the minerals that cause hard water, so you will notice an improvement in the taste and quality of your water. Your appliances will not suffer from scale build-up, your dishes will feel cleaner, your clothes will be brighter, and you will be able to wash your hands with soap and see the soap bubbles.

A salt-based system will use electricity and produce water waste, thus raising your power and water bill. There is also more maintenance required with salt-based systems (the former are pretty maintenance free). However, if you want a true water softening system that completely eliminates the elements that cause hard water, a salt-based system could be your choice.

What are a salt free water softeners?

Pelican Water Softener

On the other hand, a salt-free system uses Template Assisted Crystallization, a process that converts calcium and magnesium into crystals that don’t stick to the water’s surface. This process does not remove the minerals, but it causes them to change their form, so they don’t harden the water. Because nothing is flushed away, salt-less softeners do not require electricity or produce water waste.

A salt-less softener does not remove minerals that cause water hardness. Instead, they change their form so that they will not negatively affect your appliances and pipes. Minerals that cause water hardness, such as Calcium/Magnesium, are not harmful to your health. In fact, they are essential minerals that we all need. A salt-less softener does not remove anything from the water, which is why they are often called “conditioners” or “descalers.”

Still, you are getting the same effects of softer water. Many people don’t want to use chemicals in their homes, and a salt-less system does not use any. Generally, salt-less systems are easier to install, easier to maintain, and always more eco-friendly than their counterparts. If these benefits are important to you, then a salt-less system is what you want. It is important to note that if you have high levels of hard water, a salt-free softener may not be able to produce the desired effects.

As far as which one is better, there is no right answer. The answer depends on what you are looking for in a softener.

Benefits of a Salt Free Softener

Top view of a water softener system

There are several advantages to salt free water conditioners that set them apart from traditional water softeners.

1. Simple installation

A softener that does not use salt is simple to install since the system consists of a single tank or cartridge. Most homeowners have no problems installing a salt-less softener on their own.

2. Low maintenance

Since water conditioners don’t go through backwash or regeneration cycles, they do not use drain connectors or require storage tanks that control valves to monitor flow and initiate back-washing cycles. They don’t require salt or chemicals, so the system itself is pretty maintenance free —a huge perk!

3. Environmentally friendly

As mentioned, since salt-free softeners do not go through regeneration cycles, they produce no water waste. They also don’t require electricity or salt, meaning they are safer on the environment, and your wallet, too.

4. Cost-Effective

A salt-less softener saves you money down the road. You will not need to prematurely replace your appliances and pipes, your clothes and dishes will appear brighter and cleaner, and you will spend less time cleaning, overall.

The Bottom Line?

Looking for a salt-less softener can be an overwhelming venture, but it doesn’t have to be. Keep in mind the main benefits that these systems provide and base your research experience on what, specifically, you need in a softener for your household.

With a salt-less free softener, you will reap the benefits of softening without the maintenance, chemicals, and cost that comes with a traditional softener. Our four recommendations are excellent choices!
