Best Salt Free Water Softener Reviews

Eddy Electronic Water Descaler

Hard water can be a nuisance. It contains minerals that accumulate film and scale on home fixtures and utensils, make clothes dingy and can even clog water pipes. The hardness property is caused by high levels of calcium and magnesium. If your house has hard water then you might need a system that can make it soft.

One very great option is using saltless water softener solutions. Such softeners are different from salt based ones in that they use magnetism or electricity to neutralize the pesky compounds. Their biggest advantage is that they are very easy to maintain. This salt free water softener reviews a variety of products for you to choose one from.

Saltless Water Softeners - Do They Work?

Some water purists do not think that salt-free systems are real water softeners. The argument is based on how they work. They are usually installed in the main water pipe (at the point where water enters your house). The installed unit sends a range of frequencies that agitate water molecules through the water line. That results to change in limescale’s crystal structure which in turn allows water to flow freely and without causing buildup.

Whereas the system does not actually make the water soft, it has been proven to prevent all the unwanted damages that are caused by hard water. So, does it work? Yes, it does. However, in case a softener does not satisfy your needs you can always complement it with a filter. Check out the differences and similarities between softening and filtering here.

Benefits of Salt Free Water Softeners

There are so many benefits of salt free water softeners. They include the following:

  • Require very little effort as far as maintenance goes. That is because you don’t need to buy chemicals or salt to sustain the system.
  • Environmentally friendly since they don’t operate using electricity and they don’t produce any waste materials.
  • Ideal for people on a low sodium diet because they reduce the amount of sodium in-house water.
  • Most are compact systems.

Below are four of the most recommended salt free water softeners. For reviews on more systems, check out our water softener reviews.

Nuvo H2O Salt-Free Water Softener

Nuvo H20 DPHB Home Salt Water Softener System

Nuvo H2O is one of the highest rated units in most salt free water softener reviews. It uses chelation technology to soften water – a process where hard minerals (particularly sodium) are made soluble. That ensures they don’t stick to each other and thus on surfaces. It has compact cartridges that require periodical replacement after every six months. The system itself will notify you when it is time to buy a new one.

Best for: Small to average sized home.


  • Features a capacity of 50,000 gallons. That should last an average family eight months and over.
  • Fairly easy to install.
  • Comes with instructions for installation and maintenance
  • It is eco-friendly
  • Fairly affordable
  • Small enough (24 by 5 inches) to fit perfectly in a small or average home.


  • Can leak if the gasket moves out of place
  • Not effective for a large home (anything that measures more than 1,100 by 2,000)

Clearwave Electronic Water Softener

Clearwave Electronic Water Softner

This is yet another affordable and reliable water softening system. It is equipped with a chip that sends low-frequency electromagnetic pulses through water pipes. That stops scaling of mineral salts that usually make water hard.

Since it uses frequencies, you should ensure that any other frequency emitting appliances are stationed at least 10 feet away to avoid interference.

Best for: Hard water with a 25-grain level.


  • It is a one-off installment that doesn’t require any maintenance
  • Very easy to install
  • Comes as a full package. You won’t have to buy anything from the store
  • Efficient with power. It uses only 5 watts
  • Very effective; especially if you deal with limescale before you install the unit
  • Comes with 90 days money-back guarantee


  • Can interfere with other frequency emitting appliances
  • Removes scale and build up but does not actually soften water

Aquios Full House Water Softener and Filter System

Aquios Full House Water Softener and Filter System

The best thing about this saltless water softener is that it filters and conditions water and also eliminates scales. It does all those things without pressure loss. Just like the Nuvo H2O Water Softener, it doesn’t need maintenance or electricity but has to be replaced after every six months.

The technology used in this system leads to commercial grade water conditioning and carbon block filtration. It involves the use of a polyphosphate additive known as Siliphos to prevent minerals from building up in your water pipes. It also eliminates chlorine, sediments, and any other harmful materials.

Best for: High-quality water softening.


  • Has a sleek and compact design
  • Comes with a 20-year warranty
  • Friendly to the environment
  • Has a high capacity of 40,000 gallons
  • Water doesn’t lose any pressure


  • It might take some time to eliminate the buildup

Aquasana Water Softener and Filter System

Aquasana EQ 1000 AST AMZN Premium Rhino Whole House Filter

This system not only softens water for you but also conserves the environment. In fact, it is one of the most environment-friendly water softeners in the market today. That is because it uses a technology known as SLOW PHOS salt-free water softening to remove the unwanted minerals from water without depositing them in the environment.

Although you can buy the water softener as a standalone product, you also have the option of buying the full Aquasana system that includes a filter solution. The filter solution removes unwanted particles like dust and also reduces the concentration level of chlorine (to the optimum).​

Best for: Commercial grade softening and filtration combo​


  • Very efficient in softening and filtering
  • Levels out PH balance in water by regulating chlorine
  • Capacity ranges but you can have a whopping 1,000,000 gallons of softened and filtered water


  • The full package is very expensive


Like most other water softener reviews, we recommend that you choose a system that suits your budget and needs. If you need another alternative to water softening then you can read our article on water purification.
