Salt-Based vs Salt-Free: Which is Better?

There are two types of water softeners: salt-based, which are more common, and salt-free.

Salt-based water softeners actually remove hard minerals such as calcium and magnesium. This results in softer water with reduced mineral content. In many cases, it will increase the sodium content of the water, however.

Salt-free water softeners really aren’t water softeners at all. They’re best referred to as water conditioners. They do not remove hard minerals. Instead, they stop the minerals from sticking to your pipes and appliances, by crystallizing the hard minerals and altering their structure.

Which is better? It depends on what your goals are. If you intend to simply protect your pipes and appliances from mineral buildup, a salt-free water conditioner will be your best bet. If you want to actually remove hard minerals (to soften your shower water, for instance), then a traditional salt-based unit will be more effective.

There are also some considerations for those on low-salt diets. Traditional salt-based water softeners actually add sodium into your drinking water, which may be harmful to folks on strict salt-reduced diets. On the other hand, the best saltless water softeners will not increase the level of sodium in your drinking water.


Benefits of Saltless Water Conditioners 

Salt-free water conditioners are primarily used to protect appliances and reduce the buildup of limescale. Some benefits include:

Environmental Friendliness – Saltless water conditioners are much better for the environment. They don’t release hazardous chemicals into the water supply, and they use less energy than traditional water softeners.

Easy to Maintain – Saltless water conditioners don’t require nearly as much maintenance as traditional systems. You won’t have to add salt to the system on a regular basis, and you won’t have to worry about the system corroding over time.

Protects Appliances – the hard minerals found in hard water can build up inside appliances that use water (such as washing machines, dishwashers, and water heaters). Over time, this can cause the appliance to function less efficiently, and can even cause damage. Given the high expense of replacing appliances, and the high cost of electricity needed to run an inefficient appliance, it’s highly beneficial to use a water conditioner if you have hard water.

Cleans More Effectively – hard water can leave spots on dishes fresh out of the dishwasher. It can also reduce the effectiveness of washing machines, and even results in more detergent being necessary for the same load of clothes.

Reduces Limescale Buildup – limescale and mineral deposits can cause unsightly stains on faucets, sinks, showers, and more. While typically not harmful in any way, they can make an otherwise sparkling kitchen look a bit lackluster – and they can be hard to remove. The best salt-free water softener will help by neutralizing the hard minerals, preventing them from sticking to surfaces.

Less Sodium – salt-based units can actually increase the amount of sodium in your drinking water. For those with cardiovascular health concerns, this can be a problem. Salt-free units do not alter salt levels, so they may be a better choice for those watching their salt intake.

What to Consider When Choosing a Salt-Free Water Softeners

When you’re choosing a salt-free water softener, consider the following: 

  • The size of your home and the amount of water you use on a daily basis – a larger home or one that uses a lot of water will require a more powerful water softener. 
  • The hardness of your water – the harder your water is, the more likely it is that you’ll need a higher-capacity water softener. 
  • The warranty and service agreement that came with the unit – a good warranty will give you peace of mind in case something goes wrong, and a good service agreement will ensure that you always have access to expert help when you need it.

How We Chose 

Flow Rate: The flow rate is the measure of how much water can be treated in a given period of time. A high flow rate means that more water can be treated, which is important if you have a large household or if you use a lot of water. 

Filter Capacity: We picked units that had a high filter capacity, so they would last a long time.

Reviews: We chose units that had earned good ratings in salt-free water softener reviews – both from customers and from industry experts. A high filter capacity means that the softener will be able to remove more impurities from your water, resulting in softer, better-tasting water. 

Durability & Value: We looked at the long-term outlook for each unit to determine how long it would likely last, and how much value it offers over the course of its lifetime.


A salt-free water softener is a great way to improve the quality of your water without adding salt or chemicals to your home. These devices use a variety of methods to remove minerals from your water, leaving it softer and cleaner.

When shopping for a salt-free water softener, keep in mind the size of your home, you may not need as large of a unit as someone with a bigger home. You’ll also want to consider how much water you use. The more water you use, the more often you’ll need to regenerate the unit.
