It is also a solid choice if you care about the environment because it uses no electricity and has no wastewater.

This water softener works based on the chelation process, it binds the citric acid to the mineral ions found in hard water. This prevents those “bad” mineral to react with soap and cause scum. It is also benefic for your water heater, plumbing fixtures, and appliances it extends their life.

The active agent found in citric acid removes the present scale build-up and helps you prevent it from affecting negatively your household.

A take on hard water

First of all, what is hard water?‌

It is water which contains high amounts of mineral ions, the most common ions found in hard water are calcium and magnesium. But those are not the only mineral ions found, some certain areas may have iron, manganese, aluminum, and others.

These metals can dissolve in water and can react in a harming way. Those minerals are the reason why your faucets have spots on them. And this is not the only problem that it can cause when soap comes in contact with hard water it forms a solution called “scum“.

However it does not only causes problems, but it also offers you many health benefits compared to soft water. You see hard water is a problem only for the household because of these two minerals:‌ calcium and magnesium.

But for human health, calcium and magnesium are considered essential nutrients. Which means that you’ll need to add them in a diet to assure a healthy body function.

Studies done on the health effects of soft water show that people who drink great amounts of soft water have more heart disease incidents, higher cholesterol levels, and blood pressure, also faster heart rate than people who drink hard water.

Calcium besides having many positive health effects is an essential component for the bones. It helps to prevent kidney stones, stroke, hypertension, obesity, and life-threatening and painful ailments like osteoporosis. Magnesium has positive effects too but inadequate can have a harmful impact.

How does citric acid softening works?‌

To get a better idea about this topic, let’s see how water softening works in the first place.

Water softening is a process that removes certain minerals ions from hard water in order to keep them reacting with detergents, appliances or even your skin and hair.

The water can be softened either by completely removing the metallic ions or by binding with the metallic ions and form harmless ions that don’t react all together with surfactants. (detergents, soaps)

Now the conventional water softener which uses salt actually removes those mineral ions and stores them. When the water passes through the salt softener the harmful mineral ions get extracted by the resin beads and the process is called ion exchange.

In time those beads are going to get clogged by the mineral ions which they extract, and they’ll need to be regenerated. The regeneration process uses salt to form a brine solution which “cleans”‌ the resin beads.

In conclusion, salt-based water softeners actually remove and store the mineral ions inside the resin beads, then they get disposed during the regeneration process.

On the other hand, the citric acid softener works based on chelation.

Chelation is a bonding between molecules and ions to metal ions. Many commercial detergents already use chelating agents like NTA, EDTA and smaller amounts of citric acid.

A study was made to analyze the effects of chelating agents on extracting the heavy metals from water, agents used were citric acid, EDTA and OA. The results show that the analyzed chelators were effective in removing heavy metals from contaminated waters.

A citric acid water softener works by linking hardness ions to a small amount of citric acid metered slowly into the water source.

And because this process uses citric acid as a chelation agent, it prevents scale build-up up to 99%‌ and it removes the present scale on your fixture or appliances.

It can also make soap and detergents way more effective. When you chelate metals to hard water it lets them produce more foam and be more active in cleaning, without the need for a conventional water softener.

Benefits of using a citric acid softener

Gets rid of limescale

When you switch to a citric acid-based water softener the already established limescale gets softened. Its also going to improve the life of your pipes since citrus is working actively to remove buildup that was causing problems in the past. Areas, where limescale was a problem, can begin to recover, you’ll notice the change especially when scrubbing the sink and bathtub.

Less maintenance

Every water softening process uses a filter of some kind that needs to be cleaned and ultimately to be replaced. A conventional water softener will need maintenance which may seem complicated for you.

Also depending on how often it regenerates the salt will need to be replaced, a bag of softener salt weighs around 40 pounds. That can be quite hard for some people to lift.

A citric acid softener has filters that may weight up to 5 months and they need to be replaced once per 6 months. Also, the average flow rate is higher and there is no wastewater.

You’re already using the powers of citric acid.

Carefully read the back of your kitchen or bathroom cleaning products they contain citric acid. Manufacturers of cleaning products have acknowledged that citric acid is a great active agent, which removes soap scum, water spots on dishes and it helps to form foam in hard water. A citric acid water softener uses the same benefits.


That’s all there is to it, a citric acid softener works great at removing hard minerals from your water but don’t expect it to do wonders. It’s gonna help you get rid of annoying problems that come with hard water like soap scum and scale build-up.

  1. Would this work to eliminate the calcium ring in my pool. I have 15000 gal pool. It would be installed on the pool water supply line.?

    • Hello Ray, This device is meant for home usage, it sure can definitely remove calcium and the model meant for 4 or more residents can filter 50,000 gallons of water before needed to be changed. For your issue, a product like this would make more sense.
