5 Best Salt Free Water Softeners

Hard water can cause scaling and clogged water lines and many households suffer from its negative effects. So, whether you are on city or well water, it is always important to look for the best water softening solution available. Although traditional salt-based water-softening systems are very effective in removing contaminants and softening hard water,  they may not be very suitable for people who must restrict their salt intake, and in addition to this, they can be very expensive as compared to other systems of softening water.


Salt-free water softeners are gradually becoming one the most popular and sought-after water softening solutions on the market. To remove contaminants or reshape them, they operate by using electromagnetic waves or filters so the contaminants no longer pose a threat to plumbing. Salt-free water softeners don’t require a constant flow of salt, they can fully operate without electricity and they are completely maintenance-free and cost-efficient.

5 Best Salt Free Water Softeners

More and more systems are coming into the market as salt-free technology keeps evolving. With many options available,  knowing which system to buy can become a daunting experience.  In this article, we give you tips on how to decide which water softener is the best one for your home and we offer a collection of the best product options to choose from. Let’s dive in!


How Salt-free Water Softeners Work

To render a benign crystalline structure, the system completely alters the composition of magnesium and calcium ions present in the hard water. When it becomes mechanically stable, the heatproof crystals eliminate lime deposits that embed into pipes, appliances, or fixtures. TAC is a process that changes the composition of hard water minerals in treating it. This is what prevents the minerals from sticking to surfaces or causing scale. TAC can be achieved in different ways. Some systems use a magnetic or electric current while other systems use a special resin bed


What is a Salt-free Water Softener?

This is a water softener that doesn’t use salt but rather uses another softening process to crystalize hard water minerals, rather than removing them entirely from the water. It removes magnesium and calcium that cause hardness through an ionic exchange.

The process then replaces them with sodium compounds or soft potassium. Salt-free technology completely eliminates the use of minerals or chemicals to generate conditioned water without the negative effects of hardness

Why salt-free water softeners are the way to go

It’s space-saving

Unlike salt-based water softeners, salt-free water softeners do not require two large brine and resin tanks. They generally contain the resin required for the TAC in a single tank. However, if you purchase a magnetic water softener, you won’t even need a tank; it just uses magnets which are placed on either side of the water tank.


It doesn’t always use electricity

A salt-based softener at all times needs to be hooked up to a power supply so it knows when to regenerate and as such, you can’t use it without electricity. This is not the case with salt- free water softener. It is important to know that although some salt free water softener systems will need to be connected to a source of electricity, most of them don’t.

It doesn’t waste water

Salt-Free Water softeners do not require water during the water softening process and as such, do not waste water. This is not the case with salt based water softeners as waste is unavoidable with them. This is because once the resin tank is full to capacity with calcium and magnesium ions,  it must be flushed out through water.

It’s low-maintenance

With salt-based water softeners, you will also need to frequently top-up your salt and be abreast of dealing with rising issues. This means it needs a lot of commitment. Salt-free water softeners on the other hand,  require no maintenance at all. The system operates using the TAC media and only requires you to replace it once every 6 years. With magnetic softeners, you don’t require any replacement or maintenance all once you purchase it.

It doesn’t remove healthy minerals from water

Salt-based water softeners completely eliminate calcium and magnesium ions from water and although these minerals Can be very frustrating,  they are also good for our health. They give water an alkaline taste which a lot of people enjoy. This is not the case with salt-free water softeners. They simply change the structure of these minerals which means you can still maintaining their health benefits without the hard water issues


It doesn’t add salt to water

Salt-free water softeners do not add salt to your water which is good for people who are on a low-sodium diet or for people who do not want to take in a lot of salt.


The best smart water softeners you will find on the markets are those that are certified by third party organizations. Although this is not a requirement, it gives the confidence that the product meets certain set standards by these organizations. These are the crucial factors you should consider and as such, should be on the top of your list. You should take your time and decide whether a unit will be suitable for your home or not – it is always  better to purchase the best smart water softener system than waste your time and money on a poor quality one.

The Pelican NaturSoft comes with a media that features calcium carbonate structures on to surface. Pelican NaturSoft does this by attracting dissolved hardness minerals and pulling them into a crystallized surface.

The crystals on the media then enlarge as a result. Due to the formation of the movement of the water on the crystalized surface, pieces of these newly crystallized hard water ions break off and go back into your plumbing. This reduces their ability to stick to surfaces. These suspended particles not only remove pre-existing scale but also prevent future scale from forming.

This technique of scale prevention will reduce your detergent and soap use, expand the ghetto lifespan of your appliances, offer cleaning benefits, and much more. The Pelican NaturSoft comes with a media that lasts for 12 years. The pre-filter only needs to be changed every 6 to 9 months and it comes with a lifetime warranty.
