Best Salt-Free Water Softeners – Reviews & Buying Guide

The water containing calcium, magnesium is called hard water. We can’t drink hard water as these minerals are removed from the water to make it softer. Making the hard water softener provides many benefits, including preventing scale build-up and blockage, which automatically extends the life of plumbing and appliances.

The best salt-free water softener works by replacing calcium, magnesium ions with sodium ions making the water softer. This whole process takes place in the resin beads. When the hard water passes through the softener, the ions get attracted and attached to the resin beads.

Buying guide for the best salt-free water softener


The best salt-free water softener is used to remove calcium, magnesium, and other minerals from the water to make hard water softer. There are many benefits of a water softener as it prevents scale build-up and blockage from extending the life of plumbing and appliances. Before buying a salt-free water softener, there are several things to consider as these things will help you choose the right. Making the right choice will help you end up having a system that works efficiently for a long time.

What type of system do you need?

Before choosing the water softener, you have to confirm what problems you are facing and what system will help you solve your problems. It is best to buy a water treatment analyzed by the professionals and considered to solve all the conditions. Once the analysis is done, then you can have the right water system. The best choice is to buy a water softener to know precisely what it does and how it works. Additionally, don’t forget to make sure you are not expecting too much or too little according to the purchase.

Get high-quality components and a metered style valve:

Always remember that good water softeners have quality components and a metered-style valve, which makes the water softener last long and work more efficiently. Having high-quality components makes the water softer expensive, but these high-quality components can make it last for years, so you don’t have to pay again and again. Apart from that, the metered style valve less the operating cost and make it run for too long. Poor components need replacements again, making the long-term cost much more than you realized.

Additionally, with a metered style valve, you can also set different hardness levels according to the people living in a house. With this setting, the system gets its automatic clean up making the system cost-effective.

Purchase the right size system according to your home:

The water is softer for you but should depend on the family member living in the house and using the water softer. There isn’t any specific size of the water softer, so its flow rate and water hardness level should be checked before buying. Too small a system in a big family will reduce the lifespan of the components, which will cost you money for its replacements. Not only this, a too-large system will have a lot of sanitary problems by wasting a lot of salt and water. So, make sure to buy a system that fits exactly in your family size and works more efficiently. So, you don’t have to pay after every month on its components.

Test your water before buying a water softener:

Sometimes water needs proper treatment, not only a water softener to prevent any ill effects on your health. Maybe you also need water filtration with a water softener system. Buying a system having both qualities can save you money and work better. If you are using city water, go to your local water district and request a water analysis copy. Some people prefer a water filter with a water softener even though the analysis report shows no problem. This is because of taste or sometimes particulate issues in the home.

FAQs about salt-free water softeners:

Before buying anything, many different questions come to our minds about buying a salt-free water softener. A few of them are listed below, which will clear almost all of your queries.

Which is better, salt or salt-free water softener?

A saltwater softener will be your best choice because the salt-free softeners build crystals or hardness; however, the minerals remain in your water. These crystals are the main cause of scale build-up in your pipes.

Is it better to drink hard or soft water?

Soft water contains low minerals as compared to hard water. That is why soft water drinking is worse than drinking hard water because of its few health benefits.

Can bacteria grow in a water softener?

Bacteria and fungi can easily grow in a water softener when your water softener is not disinfected before softening.

Why are water softeners bad?

If we talk about the safety of water softeners, then, unfortunately, salt-free water softeners can cause a lot of different environmental problems. The salt build-up in an aquatic environment is a hassle as all the water softeners release chloride salts.

Can you soften water without salt?

A Salt-free water softener doesn’t soften water, as they only crystalize the calcium. On the other hand, salt-based water softeners remove all the minerals and also lower the hardness.


Always make your choice with care before buying the best salt free water softener. You need to be sure that the system you are buying should work smoothly and efficiently for a long time, so you don’t have to pay again and again. You can easily pass years without worrying about the water softener.
