The Best Salt-Free Water Softeners of 2022

Below are the best salt free options for softening water. Each softener is effective and easy to install.

1. NuvoH2O Home ‎H2O DPHB (Salt-free) – Best Citric Acid Option

The NuvoH2O Home ‎H2O DPHB (H2O DPHB) is a water conditioner suitable for small to mid-sized households with typical water use.

NuvoH2O Home ‎H2O DPHB
  • Reduces existing limescale buildup
  • Doesn't remove beneficial minerals
  • An eco-friendly alternative
  • Not ideal for extremely hard water

This NuvoH2O model uses the chelation process to change the behavior of calcium and magnesium ions in water, altering the pH levels. During the process, chelating agents bind hard water-causing minerals and keep them soluble. The action prevents the minerals from sticking to surfaces.

The home softener system features a cartridge in place of salt and resin to condition your water. Resulting in water that's healthier, softer, and better for use with most household appliances.

Inside the cartridge is citric acid. Water pressure pushes a bit of acid at a time. However, the acid amount is tiny and doesn't change the water's taste.

NuvoH2O recommends this softener system only if your water has a pH of at least 7.2. The recommendation ensures water will not get too acidic and corrode your pipes.

This citrus-based chelation process is suitable for mild and medium-hard water. The manufacturer claims the chelating agent in the system is FDA-approved and completely safe.

The water conditioner system provides up to 15 GPM, so you won't notice changes in water flow. Cartridge in the unit lasts about 20,000 gallons before replacement—or every four to six months.

This NuvoH2O system is straightforward to set up and comes with everything you require out of the box. Packaging includes a housing unit, wall mounting panel, housing wrench, and screws.

There is also a bypass valve included. It is a critical feature when you require large amounts of water, and you'd rather not waste the cartridge.

Bottom Line This NuvoH2O system is ideal for small and average-size households, especially if you don't have space for a larger softener. Plus, the chelation system is usable in every state, including areas where there's a ban on ion exchange systems. View Latest Price on Amazon →

3. AO Smith Salt-Free Water Descaler – Best For Larger Households

AO Smith brings you a system that kills chlorine odor and taste in your water. Knowing what a system can and cannot do is the key to getting the right water filtration solution. This AO Smith Water Filter is the central contact point for water entering your home.

AO Smith
  • A reliable water descaler
  • Easy installation
  • Durable construction
  • The house water filter works with well and city water
  • Zero maintenance
  • Unit does not come with a softener or filter
  • Must replace the entire unit at the end of its service life

6. YARNA Capacitive Electronic Water Descaler System – Best Value for Money

The YARNA water descaler system is a salt-less water softener that helps prevent scale buildup using electric impulses. It is also one of the cheapest options on this list.

YARNA Capacitive Electronic Salt-less Water Softener System
  • Easy to install on any pipe up to 2 inches
  • Attaches to the exterior of pipes
  • Uses electrical pulses to descale your pipes
  • Softens while leaving magnesium and calcium
  • Only one descaler per household

Bottom Line This YARNA descaler is an excellent option if you're looking for a zero-maintenance, affordable salt-free softener that doesn't need an invasive installation. View Latest Price on Amazon →

7. Eddy Electronic Water Descaler – Best Electric

The Eddy Electronic Descaler helps soften your water, but at a fraction of the cost. It requires no maintenance, takes no space, and is eco-friendly.

Eddy Electronic Water Descaler
  • Up to 75% cheaper than a softener
  • Uses less electricity compared to a softener
  • Only needs a 28-square-inch space
  • Helps keep healthy magnesium and calcium in the water
  • Easy to install
  • Can't use on iron and lead pipes
  • Not great for households with an over 20 GPG water hardness rating

This electronic water descaler from Eddy is a salt-free water softener alternative that requires no salt. Two small wire coils wrap around your water supply line and create a magnetic wave that transforms the behavior of minerals in the fluid.

The descaler doesn't change the chemical composition of water. While salt-based softeners remove magnesium and calcium, this Eddy product suspends them so they don't stick to the pipes. Your appliances and plumbing breathe a sigh of relief while your body benefits.

Installing the unit takes only a few minutes—even with no experience. This Eddy descaler works with all metal and PVC pipes apart from those made from lead or iron.

Every water drop flowing into your home gets the treatment. All you require is a standard 110-volt electrical supply, and power usage is minimal. The unit comes with a 12-month satisfaction guarantee, and Eddy will replace or repair it for free.

Unlike other water softener products, the descaler will not affect your water flow. Eddy Electronic Water Descaler treats up to 20 GPM. The treatment flow is above the 15 GPM max flow rate of most homes.

We should mention that this Eddy unit is not a water softener—it's a conditioner or descaler. The unit doesn't remove hardness-causing minerals in the water. Instead, it will condition your water as it flows through the main pipe into your home.

Bottom Line This Eddy Electronic Water Descaler is an excellent option if you're struggling with hard water but are reluctant to commit to a salt-free water softener. You get money back if the product does not perform to your expectations. View Latest Price on Amazon →

8. Aquasana Salt Free Water Conditioner – Best Budget Option

The Aquasana Salt-Free water conditioner reduces the adverse effects of scale and corrosion to protect your plumbing and appliances. Aquasana is always surprising households by offering some of the most cost-effect house water systems on the market.

No image available
  • Improved water taste
  • Several optional add-on features are available

It will not replace an entire home water filter, but it protects you from scale and removes impurities. View Latest Price on Amazon →

What to Consider When You're Buying a Salt-Free Water Softener

As mentioned earlier, there are things you'll want to consider when choosing a salt-free water softener. This section details each feature.

The Capacity

The capacity rating of softeners means counting grain or the number of grain minerals a unit removes before flushing the remaining material.

However, salt-free water softeners don't flush filter resin material. They keep grain ratings to show how long a unit lasts or effectively filters hard water particles.

Therefore, test the water before shopping for a softener. The water tests tell you the number of mineral grains present in a gallon of water. This result then tells you the grain rating you need to be on the lookout for.

You can inquire from the city about allotted grains per gallon in water. But note there's a big difference between well water and city water. Most cities have a tolerance of about 15 GPG, while well water may have as much as 40 GPG.

The Water Flow Rate

Salt-free softener water flow rate differs from that of a traditional softener.

Salt-free water softeners don't flush filtered materials and instead have a catalytic media that crystallizes material ions on the media surface while maintaining water flow. The system media stays fluid and pulls the hardness crystals from the surface.

Consider each system's water flow rate to determine if it's right for your household.

Some systems reduce water flow while passing through it, which affects the water pressure in multiple locations. For example, the average washer requires 1.5 gallons a minute, while the shower uses 2 gallons per minute.

System Type

There are several types of saltless water softeners on the market. The three main types are TAC, chelation, and electromagnetic.

Template Assisted Crystallization (TAC)

TAC is the most popular means of softening water without salt. However, a TAC conditioner is not a softener, but it provides almost similar results to salt units.

The TAC process treats hard water minerals in your water supply and changes the chemical composition of minerals to prevent scale formation. TAC media offers all the benefits of soft water and maintains healthy minerals.

Resin in a TAC conditioner attracts the hard water minerals in the water. These minerals remain in the resin until they crystallize and are released back into the water.


A water conditioning process binds hard water ions to a chelating agent, such as citric acid or ethylenediaminetetraacetic acid (EDTA). The mineral ions suspend in water and cannot deposit themselves on surfaces as scale.

Chelation is popular in commercial applications, but several in-home chelation conditioning systems are available.


An electromagnetic water conditioner uses electromagnetic coils to separate the hard water minerals and prevent them from creating scale.

The process doesn't require tanks. Electromagnet conditioners have a pair of magnets or a coil that attaches to the outside of a water pipe. The magnetic process intercepts water before reaching the heater.

Electromagnet conditioners are affordable salt-free softening options, but there's little evidence the systems work.


Check the materials that make your salt-free water softener. Studies point out that Bisphenol A (BPA) in some plastic is a carcinogen, so make sure you don't get a model that fills your household with BPA. Materials without BPA include stainless steel metals and BPA-free plastic components.

Maximum Pressure

Each salt-free water softener model has different maximum pressures. Weigh the unit's max pressure against your current water pressure.

Don't get a unit that will take up most of your current water pressure. Remember, installing a softener decreases pressure.

Chlorine Reduction

Read the product specs for information on whether the model will filter chlorine. A full-filtering model can help change the chlorine in your household water.

Unit Dimensions

Salt-free water softeners vary in size. Consider if you have space for a unit you're looking at.

Each unit has dimension information, so read them and measure twice and confirm. There's nothing worse than purchasing a softener, and it doesn't fit.

Operating Temperature

The operating temperature depends on the model you want. Ask the manufacturer if there's no information of the operating temp on product specs.


Check the warranty and see what's covered and how long it runs. Consider buying an extended warranty from the manufacturer if you're getting a short warranty. The warranty protects you in case something goes wrong with the softener.

Ease of Installation

If you don't have experience installing a salt-free water softener, always hire a professional.

You'll need to shut off the main water supply before you can touch the plumbing—and many things can go wrong. While installing a salt-free unit is easier than doing the same for a salt-based system, some devices can be tricky.

The Last Word…

Between the reviews and buyer guide, you're now ready to rid yourself of the pesky minerals and enjoy some salt-free soft water.

However, we want to clarify that water from a salt-free system is not actual soft water. With soft water, all the hard water minerals have been removed. These salt-free conditioners only reduce the scaling effects of hard water without taking out any magnesium or calcium.

The mineral composition of hard water offers us a ton of benefits, including protecting your bones and heart. Salt-free water softeners ensure you get the benefits without damaging plumbing fixtures and water appliances.

We are confident that the information provided in this guide will help you find the best salt-free water softener for you.

Go salt-less today and enjoy the benefits of saltless soft water!
