What Is the Water Softener for Well Water

Iron, magnesium, and calcium are among the most common elements that make well water hard. Hard water can cause problems at home—it leaves soap scum and scale buildup on your plumbing fixtures, bathroom fittings, and appliances. Plus, it can dry up your skin and hair.

Don’t let the hard well water issues overwhelm you because you can get rid of them with the right water softening system.

Choosing the best water softener for well water should not be a hassle if you know exactly what to look for. We have conducted detailed research and found nine products that are uniquely designed to soften well water.

Top Pick

Iron Pro 2 Combination Water Softener is our top choice for this review roundup. This is a combination system designed to remove hardness minerals like magnesium and calcium. It is also rated to remove up to 6-8 ppm of iron, making it our overall best water softener for well water with iron.

Best Water Softener for Well Water

Things to Look for in the Best Water Softener System for Well Water

Buying the best water softener for well water can be a challenging task, especially if it is your first time. How do you intelligently choose among the wide array of products on the market today?

The following factors will help you find the best water softener system for well water.

Types of Water Softeners for Well Water

There are three popular types of water softening systems: salt-based water softener, salt-free water softener, and electronic water descaler.

Salt-Based Water Softener

A salt-based system is made up of a brine tank and a resin tank with a control valve. All the water in your house passes through the media/resin tank and passes over the resin/beads.

Ion exchange occurs in the media tank. The hardness minerals such as magnesium, calcium, and traces of iron are replaced with sodium ions and passed out of the system. You’ve got a meter inside the valve that measures the number of gallons that go through the system. When you get close to exceeding the capacity of the resin to soften any more water, the resin will be regenerated and the tank needs to be cleaned out.

There are two types of salt-based water softeners you can use with well water: upflow and downflow systems.

Upflow Vs Downflow

This is an important factor to look at when you consider water and brine efficiency. Brine efficiency (grain per pound) refers to how much salt the system uses to extract hardness minerals and iron from your well water. Water efficiency (gallons per regeneration), on the other hand, refers to how much water the softener uses during the regeneration process.

In a downflow system, the brine flows through the water softener in the co-current direction. In an upflow system, the brine goes through the water softener in the countercurrent direction.

This feature makes an upflow system more brine and water-efficient compared to a downflow system. An upflow water softener will only recharge the resin that is depleted and pushes the hardness away from the resin.

Salt-Free Water Softener

Salt-free water softener systems use template-assisted crystallization to reduce hardness in well water without the use of salt. This type of water system sends water through a fluidized bed of millions of tiny beads.

Hard minerals like magnesium, calcium, and iron interact with the bead surfaces and create soft scale microcrystals. The microcrystals rapidly break off due to the flow of moving water and are released as inert particles. These microcrystals continue to snowball through the water softener, picking up other hard minerals. The restructured molecular makeup of the microcrystals does not form destructive hard scale buildup on plumbing fixtures.

The biggest problem with this system is that it doesn’t remove the hard minerals from the well water. All the calcium, magnesium, iron, and other elements will be present in the water in the form of microcrystals. This explains why the water is never truly soft.

Electronic Water Descaler

An electronic descaler doesn’t use template-assisted crystallization or ion exchange to crystalize or remove hard minerals from well water. Instead, it introduces an electromagnetic field into the water that restructures the properties of magnesium, calcium, and iron. This ensures that the deposits pass through your plumbing fixtures without sticking on the surfaces. Like a salt-free water softener, this system doesn’t remove hard minerals and iron from your well water.

Sodium Vs Potassium Resin

Salt-based water softeners, which come highly recommended for well water, can use either sodium or potassium. Both do the same thing of replacing hard minerals during ion exchange.

Potassium chloride replaces magnesium, calcium, and iron with potassium ions, while sodium chloride replaces calcium, magnesium, and iron with sodium ions. But you will certainly use more bags of potassium chloride as compared to sodium chloride. Potassium resins are more expensive but septic-friendly.

How to Size a Water Softener

As an example, we will work through the sizing calculation for a typical family of four. Apart from the number of people in the household, you also need the number of gallons each person uses per day, the hardness of the well water, and the iron levels of the water.

You can determine the hardness of your well water with a water kit and iron levels with an iron test kit. On average, a single person can use roughly 75 gallons per day. Let’s estimate the hardness of the water to be 20 grains per gallon (GPG) and the hardness of iron to be 5 GPG. The daily grain of hardness to be removed will be 4*75*(20+5), which is 7,500 grains per day.

The best water softener for well water will regenerate once every week. So, if we multiply this value by 7, we will get 52,500 grains. To find the best water softener for well water with iron for this example, we have to match the 52,500 grains to the most ideal capacity on the sizing chart. This family of four will get the most effective results with a 64,000-grain system.


Can a Water Softener Remove Total Dissolved Solids from Well Water?

A water softener is not engineered to remove total dissolved solids or TDS from your well water. However, it will remove minerals causing hardness in your well water like magnesium and calcium through a process called ion exchange.

Do Water Softeners Remove High Levels of Iron from Well Water?

Generally, water softeners are designed to remove a certain amount of iron from your well water. This can be six to eight parts per million. So, if your well water has too much iron in it, then you will be better off with city water or water from a different private well with less iron content.

Are Salt-Free Water Softeners Ideal for Well Water?

You can choose to use a salt-based or salt-free water softener system with your well water. However, remember that salt-free systems don’t remove the hard minerals from the water. So, you will not get truly soft water as you would with a system that uses salt.

How Long Does Water Regeneration Take?

A water softener usually takes about two hours to regenerate. The water service is normally interrupted when the system is regenerating. Most systems are programmed to regenerate at around 2 to 4 am when everyone is asleep.

When Is the Right Time to Change the Cartridge in a Salt-Free Water Softener?

It depends on your usage and water hardness. You can physically observe the cartridge for significant changes. Alternatively, you can boil a small amount of water obtained from the system. If you see any sediments, then it is time to replace the cartridge.

Final Thoughts

For this roundup, the winner is Iron Pro 2 Combination Water Softener. It is our overall best water softener system for well water because of its ability to remove the hardness of up to 75 GPG and iron levels of up to 8 ppm. The system is also capable of removing sand and sediment from your well water.

This is a salt-based water system. So, it is very effective in removing magnesium and calcium ions by replacing them with sodium. It has a considerably large capacity of 64,000 grains, making it a great choice for well water with hardness ranging from 41 to 75 grains per gallon.
