What is a Salt-Free Water Softener?

Salt-free water softeners are popularly known as water conditions. As the name suggests, these systems alter the prevalent positive ions in hard water through a physical process called crystallization. The magnesium and calcium crystals build up in the system before disintegrating to give conditioned water on the other end. Salt-free water conditioners do not remove the hardness minerals but alter them to prevent scale buildup.

How Does a Salt-Free Water Softener Work?

Salt-free water softeners leverage template-assisted crystallization (TAC) to alter the hard mineral ions in your water. Water flows into the system through a TAC medium that features tiny polymer beads covered in nucleation site craters. These craters trap magnesium and calcium as the hard water flows through the TAC medium. The continuous flow of hard water forms small micro-crystals that eventually build up before disintegrating from the medium into the water.

The disintegrated micro-crystals are relatively stable and will flow through your plumbing system in their crystalline structure. Thus, you won’t experience scale buildup inside the pipes or around water appliances.

Salt-Free Water Softener Vs. Salt-Based Water Softener

A salt-free water softener should be a go-to option if you’re worried about scale build ups around your plumbing system and water appliances. As noted, these systems only condition magnesium and calcium ions but retain the hardness properties in your water. Thus, salt-based water conditioners outperform them when it is about softening the water. On the brighter side, these systems are relatively durable and will prolong the lifespan of your water appliances.

Advantages of the Best Salt Free Water Softeners

The top benefits of installing a salt-free water softener in your home include:

  • They maximize small spaces
  • Conditioned water without spending on energy bills
  • Save up to 700 gallons per year
  • Retains the healthy water minerals
  • Low maintenance or repair needs
  • They give salt-free water

Drawbacks to Salt-Free Water Softeners

  • They don’t give you soft water
  • They require patience to show results
  • Not as effective as salt-based water softeners

What Should You Look for When Buying the Best Salt Free Water Softener?

It will help if you consider the following before buying this product:

Complementary After-Sale Services

You should always watch out for brands that offer complementary after-sale services to guarantee 100% customer satisfaction. These services may include free shipping and installation, a money-back guarantee, discounts for first-time buyers, and lifetime technical support for registered customers.

Superior Filtration

Calcium and magnesium ions only make a fraction of your residential water source concerns. Thus you would want a system that does more than altering the hard water ions. Watch out for water softening systems that come with superior filtration technology to trap other pollutants. 

Prevalent contaminants probably present in your water source, including chlorine, heavy metals, chloramines, and dust.

Do you need an alternative water softener?

The best salt free water softener doesn’t remove hard water ions. Instead, it alters the ions, preventing them from precipitating to form scale buildup. In that case, you can settle for a salt-based water softener if you want to terminate hard water ions from your plumbing system. However, these systems leave a carbon print and may attract expensive maintenance costs.

Factors to Consider Before Buying a Salt-Free Water Softener

Picking the best salt free water softener can be a daunting task if you’re purchasing a whole house system for the first time. It can even be more difficult if many homeowners recommend multiple options that may all seem to function optimally. Consider these factors to handpick a water softening system that meets your needs and aesthetic preferences:

Initial Cost

You need to consider the entire cost of having the system up and running, including installation. You can go for brands that offer installation services or packages the system with all the components required for a quick setup. 

Also, kindly note that models from superior brands will likely cost more than generic products. Even so, the expensive price tag usually guarantees a product’s quality, efficiency, and reliability.


The only way to verify a manufacturer’s claim is by checking whether third-party certifications vouch for the same. For instance, a product described as safe for human use should come with NSF/ANSI standard 61 certifications for lead-free components. 

The NSF/ANSI certifications have various standards, and the manufacturer will always indicate what a product qualifies for. Other certifications that guarantee quality include IAPMO and WQA.


The manufacturer can indicate a system’s capacity in two ways. It can be the amount of water in gallons or the number of users/bathrooms (showerheads). Either way, the higher the capacity, the higher the likelihood of having a good experience. 

Remember, a high-capacity water softener will serve a whole house without disrupting flow rates or pressure in the plumbing fixtures. While most water softener systems will give you an average capacity of 100,000 gallons, some brands offer high capacities of up to 1,000,000 gallons.


Warranty information guarantees a product’s quality and high-performance consistencies. Most products come with limited warranties, with a few reputable brands offering up to a lifetime warranty. However, kindly read the warranty sheet to understand what it covers. 

For instance, the warranty can be on the whole system or individual parts. Some manufacturers will also give a one-year warranty on free labor for servicing and repairs (even if the whole system comes with a lifetime warranty).

Installation and Maintenance

Most consumers choose to leave installation jobs to professionals, even though they can do it in a simple DIY process. Watch out for brands that include all the components needed for installation in the packaging, including a user manual with easy-to-read instructions. 

The manufacturer should also indicate the type of installation, whether it’s indoor or outdoor. Most of the systems on this buying review come with hassle-free maintenance. You’ll hardly need any servicing or repairs in the first couple of years after installation.

System Control and Features

While many people prefer a system that comes with an intuitive user control panel, it may not be a good choice if you’re a busy or forgetful person. Remember, programmed settings can get lost due to power supply interruption. 

Thus, you can go for a system that doesn’t require valve programming, especially if you’re a first-time user. Some features to watch out for in a system include the tank’s medium lifespan, installation requirements, and filtration technology.

Flow Rate

Lastly, you would want to consider a system’s flow rate before installing it in your line. Watch out for a water softening system that can keep up with your water usage. A typical whole-house requires relatively high flow rates of 10 GPM to 15 GPM. 

A product with a different flow rate from your water line will affect the efficiency of your appliances. It may also cause power shortage in the showerheads, especially when all bathrooms are in use simultaneously.

The Bottom Line

The effects of hard water can be frustrating, especially if your plumbing fixtures clog every time. You can end this stress by installing our best salt free water softener for up to 6 bathroom applications. 

A high-quality water softener system guarantees a prolonged lifespan for appliances and low carbon print since you’ll unlikely need electrical power connectivity. All the products listed on this buying guide are of high quality and are affordable to maintain.
