It is one of the best electronic descaling systems to treat hard water.

What Did Customers Say About Yarna Capacitive Electronic Water Descaler?

  • We are on a well and have always just lived with the hard water. When I got in a shower a few hours later I was amazed at the softness of the water. The unit worked flawlessly.
  • No lime buildup around faucets, sinks, toilets. No thick crusty buildup on the bottom of the coffee maker.
  • The minerals aren’t removed from the water just like it says in the product description. They are neutralized because the sharp edges on the limescale particles are smoothed out therefore the calcium and magnesium can’t stick to anything. I compared glasses that went through the dishwasher to glasses that were washed the week before. The result was amazing.
  • After using this for the last 6 months, I found a big difference. The shower booth and toilet get noticeably much cleaner like magic. Much clear and clean tap water.

  • It was easy to install, came with all the filters and conditioners that were needed.
  • While standing water that evaporates will leaves spots, those spots are more a dusty residue that easily wipes up. The carbon filter does exactly what it’s supposed to. Tap water is now plenty satisfying to drink and the old chlorine odor is hardly present, if at all.
  • Don’t let the cost and size fool you- this water conditioner is quite a powerhouse! I have no more limescale/mineral buildup anywhere in my home, my dishes are much cleaner and brighter, water at every point in my home tastes better.
  • Works just like advertised. No surprise to me. But shocked some people when they came over and could tell the difference just from washing their hands.
  • If your expectation is that you were going to use this product to replace the salt water softener, you will be disappointed. It does not match the spot reduction of a genuine salt system. Although it is way better than no system.

Here’s What I Look For In The Best Salt-free Water Softener

The Best Salt-free Water Softener Is Giving High Value for Money

A more expensive salt-free water softener doesn’t mean it is better than the cheaper ones.

What is more important is the value – the performance, convenience, lifespan, quality, and features a no-salt system gives per dollar.

Therefore I only list out the salt-free softener systems that are worth your money.

The Best Salt-free Water Softener Is Highly Effective on Limescale Prevention

Since the main purpose of a saltless water softener is to protect your home from limescale, it makes sense that the best salt-free water softener should be highly effective on limescale prevention.

The Best Salt-free Water Softener Is Built to Last

Product quality is another important factor when comes to a device like a water softener.

The best saltless water softeners must be made of high-quality material to withstand time and can be used for decades.

How Salt-free Water Softeners (Water Conditioners/Water Descalers) Work?

Salt-free water softeners use a softening technology called Template Assisted Crystallization to alter the chemical structure of hardness minerals so that they cannot stick on the surfaces and cause limescale buildup.

In other words, a salt-free water softener does not remove the hardness minerals but condition them to prevent them from forming limescale – the main problem of hard water.

Therefore, a salt-free water softener is also known as a salt-free water conditioner as it is used to condition the hard water.

Besides, some manufacturers name their softening devices as water descaler because it is used to descale hard water.

Salt-free Water Softener VS Salt-based Water Softener: Comparison

Softening Technology

Salt-based water softeners use ion-exchange technology and salts to remove hardness minerals in hard water, whereas salt-free water softeners use technologies like Template Assisted Crystallization or Electromagnetic to alter the form of hardness minerals, render them unable to stick on surfaces and form limescale.

In other words, salt-free water softeners do not remove the hardness minerals, they only change their chemical structure to prevent them from forming limescale.

Maintenance

For a salt-based water softener, you are required to refill salts regularly depending on the water usage and water hardness level, whereas a salt-free water softener is virtually maintenance-free.

Electricity

Salt-based water softeners need to be connected to a power socket to operate, whereas salt-free water softeners do not require electricity to operate.

Type of Salt-free Water Softener

There are three popular types of salt-free water softener in the market that are commonly used as a water softener alternative to prevent limescale, they are:

  • Physical (Template Assisted Crystallization)
  • Chemical (Polyphosphates)
  • Electronic (Electromagnetic Waves)

Physical Softening (Template Assisted Crystallization)

Physical water softeners are the most popular salt-free water softener due to their advantages such as high effectiveness in limescale prevention, do not require electricity, and are virtually maintenance-free.

The most used physical softening technology is called Template Assisted Crystallization, an effective method that alters the structure of hardness minerals to prevent them from sticking on surfaces to form limescale.

Chemical Softening (Polyphosphates)

Chemical water softeners use Polyphosphates, chemicals that bind hardness minerals to inhibit limescale and corrosion.

Electronic Softening (Electromagnetic Waves)

Electronic water softeners produce electromagnetic waves to condition the hard water, magnetizing the hardness minerals to prevent them from attaching to the surfaces to form limescale.

They are easy to install and inexpensive, but the effectiveness is lower and requires electricity to operate.

How to Choose the Best Salt-free Water Softener (Read Before Buy)

There are a few important factors to consider when deciding on the best salt-free water softener for your home.

Know Your Water’s Hardness Level

To check the water’s hardness level, you may conduct a simple test with a water hardness test kit.

For a more accurate result, you can send your water sample to the lab for a hardness test. Then, you can know your water quality based on the value of GPG (Grains Per Gallon):

  • 1 to 3.5 GPG – Slightly Hard Water
  • 3.5 to 7 GPG – Moderately Hard Water
  • 7 to 10.5 GPG – Hard Water
  • Above 10.5 GPG – Very Hard Water

Descaling Performance Is Important

The effectiveness of limescale prevention is one of the primary factors to consider when choosing a salt-free water softener.

Some of the high-performance water softeners without salt can achieve above 99% of limescale prevention which makes them an ideal choice for homes with hard water.

Electromagnetic water conditioners tend to be less effective on limescale prevention, but they are cheaper, smaller, and easier to install.

Also, each salt-free water softener has its limit in treating the hard water, indicated in grain per gallon (GPG). The GPG value reflects the maximum hardness level the system can handle effectively.

For instance, some saltless water softeners can treat hard water with a hardness level of up to 75 GPG, some can handle up to 25 GPG, and some are only suitable for a hardness level up to 20 GPG.

Therefore, make sure you choose the one that can handle your water condition.

Choose the Right Softener Capacity or Size

Some no-salt water softeners are sized by the number of bathrooms in your home to make selection easier as you don’t have to calculate the grains required.

For instance, if your home has 2 full bathrooms, then pick the water softener model suitable for 1 to 3 bathrooms, if your home is large, then pick the option for 4 to 6 bathrooms or above.

The larger models also provide a higher flow rate to support more simultaneous water-using activities without experiencing pressure drops.

High Water Flow Rate

The water flow rate is another important factor to consider when comes to deciding the right salt-free water softener system.

When the hard water flows through a salt-free water softener through physical contact, the water flow rate will be restricted by the softener system.

Most salt-free water softeners come with a flow rate rating which indicates the maximum flow rate they can provide except for electromagnetic water conditioners as they are attached on the exterior of the main pipe, hence they will not affect the water flow rate at all.

A good salt-free water softener should be able to provide a flow rate of at least 7 gallons per minute (GPM).

For large households, a higher flow rate between 12 to 20 GPM is recommended to ensure no pressure drop during simultaneous use of water.

Dropped water pressure will affect the experience of water-using activities such as shower, washing dishes, and cleaning a car.

The higher the water flow rate, the more water-using activities can be carried out at the same time without experiencing water pressure drop.

Available Space in Your Home

Before purchase, make sure your home has enough space to fit the salt-free water softener that you are going to get.

You can check the dimension detail on the product page.

The available space should be enough to fit in the system and allow you to comfortably maintain it.

Calculate the Ownership Cost

The best saltless water softener for your home shouldn’t be bringing you financial stress. Hence, make sure to do the calculation first and buy the one that fits within your affordability.

Aside from the product cost, you should also take into account the ongoing maintenance cost (if there is any).

Product Certification

While a certified system doesn’t mean it is better than an uncertified system, however, a certified salt-free water softener gives you peace of mind knowing that the system is tested by a third party and certified its quality or performance claims.

The Benefits of Using a Salt-free Water Softener System

The no-salt water softener alternative offers many benefits as compared to the traditional salt-based water softener system.

In this section, I’ll discuss some of the main benefits of using a salt-free water softener.

Low Maintenance

Salt-free water softeners are virtually maintenance-free as you don’t have to refill salts, which saves you the time to hassle to buy salt bags and refill the brine tank regularly.

They also do not require cleaning or washing.

The most you need to do is replace the pre-sediment filter (if there is one) every 6 to 9 months and the process is easy and quick.

Low Long-term Ownership Cost

Unlike the traditional salt-based water softener, a salt-free water softener does not require you to purchase salts regularly and can operate without electricity, hence save you a lot of money in the long run.

Besides, all the salt-free water softener models listed in this post are priced reasonably.

Do Not Require Electricity

Most salt-free water softeners do not require electricity to operate except the electromagnetic water conditioners.

Therefore, they are not required to be installed near a power outlet and can save you on energy bills too.

Produce Healthier Water

As a salt-based water softener will release sodium into the water in exchange for hardness minerals like calcium and magnesium, therefore it is not suitable for people on a low-sodium diet.

In contrast, a salt-free water softener will not add salts into the water and retain the essential minerals (calcium and magnesium), thus producing healthier water for your family.

Do Not Produce Wastewater

Unlike traditional salt-based water softeners which often raise environmental concerns due to wastewater, salt-free water softeners are environmental-friendly and do not produce any wastewater in the softening process.

Protect Electrical Appliances & Plumbing System

A salt-free water softener can effectively prevent limescale form on the surfaces of water-using appliances and plumbing systems, which prolong their lifespan and save your repair cost.

Save Space

Unlike salt-based water softeners which require two large tanks – resin tank and brine tank, salt-free water softeners are a single-tank system or a compact device (electromagnetic water conditioners).

The smaller physical size makes them easier to locate and saves space in your home.

Retain Essential Minerals

Hardness minerals like calcium and magnesium are beneficial to our health and can improve the water taste.

One benefit of salt-free water softeners is they can retain these essential minerals while preventing them from forming limescale.

The Drawbacks of Using A Salt-free Water Softener

Could Not Remove Hardness Minerals

Salt-free water softeners could not remove hardness minerals, so they will not produce softened water.

Could Not Prevent Water Spot Completely

As the hardness minerals are still inside the water, it will leave water spots on the floors, sink, and water fixtures, but rest assured, the water spots can be washed off easily.

Less Effective Compared to Salt-based Water Softeners

While some of the high-performance salt-free water softeners are highly effective on limescale prevention, but overall they are not as effective as salt-based water softeners.

Water Treatment System Combo

Since a salt-free water softener can only treat hardness minerals and not the other contaminants, therefore you still need to use it along with other water filtration systems to achieve complete water purification for your home.

The most common combination is using a salt-free water softener with a whole-house water filtration system to remove a majority of contaminants and prevent limescale.

Installation of Saltless Water Softeners

Saltless water softeners are point-of-entry systems and should be installed at the front end of your plumbing system, usually after the entrance valve or the whole house water filter to ensure your whole house is getting the conditioned water and protect your plumbing system from limescale buildup.

Most saltless water softeners are simple to install and are suitable to be installed both indoor and outdoor. Some may take hours and some may only take less than 30 minutes depending on the size and parts.

If you are a handy person or with some basic plumbing skills, it shouldn’t be a difficult task for you to set it up.

Electromagnetic water conditioners are much easier and quicker to set up and should be installed in a covered area.

The physical type salt-free water softeners are not required to be installed near the power outlet as they do not need electricity to operate, whereas electromagnetic water conditioners are required.

Make sure to follow the instructions given by the manufacturer as the installation steps may vary for different products.

Maintenance of Saltless Water Softeners

Water softeners without salt are easy to maintain, some are virtually maintenance-free.

All you need to do is to replace the pre-sediment filter periodically (if there is any) as they do not require routine cleaning or media replacement.

The best salt-free water softeners mentioned in this review article only require low maintenance and the softening media can last throughout their lifetime without replacement needed.
