Salt-Based Water Softener vs Salt-Free Water Softener

The two types of water softeners that dominate the market are salt-based water softeners and salt-free water softeners, and the difference between the two types is much bigger than just the fact that one does not use a form of salt in its filtration system.

Salt-based water softeners uses various types of salt that remove particles and hard minerals that is in the water, it is very effective however due to salt being used often the water will have a much saltier taste and also contain a higher than average amount of salt which dries the skin and is also not good for your health if you frequently consume it.

On the other hand, you have the so-called salt-free water softeners which in reality are not really a type of softeners but are actually officially known as ‘water conditioners’ as rather than removing the materials from the water they change the structure of the metals and other minerals in the water that reduces the chances of them sticking and building up inside the piping and other surfaces.

Salt-free water softeners are also known as citric acid water softeners with citric acid being one of the main ingredients for altering the composition of the minerals and ions in the water, we go in further detail about citric acid below.

How Citric Acid Water Filters Work?

Citric acid is a type of acid that is classed as ‘weak’ and in water filters, it is used to bind ions and chemicals together in order to reduce their effectiveness of sticking and building up on surfaces that they get in contact with which can include the walls of your bathroom, pipes, and taps for example.

Like all filters, citric acid water filters need to be replaced regularly based on the recommended lifespan use as well as the amount of gallons that are filtered on average, if you happen to use up a lot of water then you will have to change the filter every month for example compared to the two months recommended timeframe.


What Is Citric Acid Used for in Water Treatment?

Citric Acid is a natural ingredient that to the average person is best known for being present in so-called citrus fruits such as oranges, lemons, limes, and many other varieties.

Apart from being a great food preservative, citric acid is also what is known as a ‘chelating agent’ which is a chemical that initiates a chemical reaction with metal ions that causes them to come together which makes them lose properties that include the ability to build upon surfaces which can damage them in the longer, cause water-based appliances to break down and also be a hub for bacteria to thrive.

At What Temperature Does Citric Acid Burn?

Citric Acid has a very high burn temperature of 153 degrees Celcius or alternatively 307 degrees Fahrenheit this makes it a safe chemical to use in water softeners as there is minimal chance of the temperature inside of those appliances heating up to such levels so you if you install citric acid water softeners then you do not have to worry about adverse reactions occurring from the citric acid burning due to such high temperatures.

Regardless it is very important to handle citric acid with care because if you do not pay attention and happen to heat up an appliance that contains citric acid then you are in danger of getting seriously hurt as citric acid turns into gas when burned and if it has no ability to leave the facility where it is contained it can cause an explosion.

Is Citric Acid Strong or Weak?

Citric acid is graded as a weak acid which means that it has a higher pH level than average and that it also causes a chemical reaction when placed in another liquid which is most commonly water.

What Is Citric Acid Used For?

Citric acid is used in citric acid water softeners to bond together different metal ions and chemicals in order to reduce certain properties which in water softener appliances are most commonly to reduce the side effects of hard water that include scaling and damage to water appliances.

Citric acid is also an essential ingredient in the salt-free water softeners that helps protect pipes and other surfaces without introducing a large quantity of salt into the water which comes with other big drawbacks to people’s health.

Do Citric Acid Water Softeners Use a Lot of Electricity?

No, Citric Acid Water Softeners do not use any electricity as it is simply an appliance that contains a filter that automatically works by itself as water is passing through it by reacting with metal ions and other chemicals that are common in hard water.

The majority of manufactures of citric acid water softeners pride themselves on their environmentally friendly initiatives that aim to limit waste and energy use.


In conclusion, there are a lot of different citric acid water softeners and salt-free water softeners to choose from. There is no clear winner that everyone must buy instead each model that we have listed in this comparison article is ideal for different types of consumers.
