🧾 Buyer’s Guide: Selecting the Ideal Water Softener System for Your Home

With the plethora of new water softener systems available, it can be overwhelming even knowing where to start.

We’ve put together this water softening system buyer’s guide to help you learn everything you need to know about how water softeners work and how to choose one for your specific needs.

There are a number of important features you’ll need to keep in mind if you’re choosing between water softening systems for your home or business:

Technology Type

There are a variety of different technology types that can be used to soften water.

The best system for you may be a salt-based system if your water is very hard and you would rather remove all mineral ions from your water. Or you might prefer salt free water softeners if you want to remove these ions, but only change their form to prevent them from producing limescale.

Grain Capacity

It’s important to choose the right grain capacity for your water softener to ensure the maximum amount of hardness is removed from your water.

To size your water softener, you need to know two things:

  • Your water hardness
  • Your water usage

You’ll find information on your water usage on your water bill. If you don’t want to work out how much water you use per day, just use the average: 80 gallons per person per day.

Multiply your daily water usage by your water hardness, which gives a figure of how many grains per gallon of hardness you need a water softener to treat.

To work out the minimum weekly grain capacity for your water softener (how many grains per gallon the system should treat per week, minimum), multiply the number by 7.

Let’s say you have 8 grains per gallon of hardness and four people living in your home, using 320 gallons of water per day. The calculation you’d do is:

8 (GPG) x 320 (daily water usage) x 7 (to achieve the weekly figure) = 17,920

From the results, you know that you need a water softener with a grain capacity of at least 17,000 gallons. Because this is only an average figure, it’s always best to look slightly higher, aiming for a softener that softens at least 19,000 grains per gallon.

Water containing iron needs a softening system with a slightly higher minimum grain capacity, so you need to add 5 GPG for every PPM of hardness when hunting for an iron removal water softener.

Resin Crosslink Percentage & Durability

All water softener resins have a crosslink percentage rating. The higher the percentage, the more durable the resin.

8% resin usually lasts for between 10 and 12 years, 10% resin can last for much longer, usually up to 20 years.

Flow Rate

The average water softener flow is between 7 and 12 GPM. The larger the system’s capacity, the higher the flow rate, equipping the softener to provide a sufficient flow of soft water to your home.

It’s important to choose the right flow for your house size and your water usage. For most families, a flow rate of up to 12 GPM is sufficient.

Regeneration Method

If your water softener needs to regenerate, it’s worth looking into the various regeneration methods available when choosing a system.

  • Metered – Metered regeneration is triggered by water usage. You’ll be required to input your water’s hardness and the size of your home when setting the softener up, and the system will calculate how much water it can soften before it runs out of salt and needs to regenerate.
  • Timed – A system that uses timed regeneration regenerates at a specific time every week. Typically, timed regeneration takes place when water isn’t generally needed, e.g. 2 am. The advantage of this type of regeneration is that you’ll never be without soft water, as you’ll know that your softener only regenerates overnight. However, this programming can also result in more water and salt waste, as your softener will most likely regenerate before it needs to.
  • Manual – Manual regeneration enables you to program your own regeneration cycle timings. This can be more convenient, as you have full control over exactly when your softener is out of operation.

Installation & Maintenance Costs

Technology type can also affect the initial costs and long-term maintenance of a water softener.

Generally, salt softeners are more expensive to purchase than salt free water softeners, and upkeep can also cost a little more.


A water softening unit can be certified by one of two independent organizations: the Water Quality Association or NSF International.

While certification isn’t a legal requirement, it generally looks good for a manufacturer to successfully certify a product they’re selling to remove iron and/or hard water minerals.

Below are the certifications available for ion exchange water softeners today:

  • NSF/ANSI 44 – a certification for cation exchange or ion exchange softeners that use sodium or potassium chloride. If a water softener is NSF 44 certified, it can remove hardness to below 1 grain per gallon, and meets structural integrity and material safety requirements.
  • NSF/ANSI 372 – a certification that ensures a water softener isn’t made from lead components and won’t leach lead into your water. Salt-based and salt-free water softeners can obtain an NSF 372 certification because this certification is about design, not performance.

Local Regulations

Before looking at whole house water softening systems, check whether your state has its own regulations and plumbing codes for water softeners.

Make sure that a system’s regeneration drain water meets requirements, and ensure that maintenance and installation processes are also in line with these requirements.

Initial Price

Most water softeners, whether they’re salt-based or saltless, are priced around the $1,000-$1,500 mark. The bigger the system’s capacity (i.e. the more soft water it can provide at once), the more expensive it will be.

We recommend setting aside at least $650 for the initial cost of a water softener. Anything cheaper than this, and you risk paying for something that doesn’t live up to expectations.

Manufacturer & Warranty

For your own peace of mind, you should only buy a water softening system from accredited manufacturers with reliable customer feedback.

Plus, a water softener should have at least a 2-year warranty for its components. Read a warranty’s terms carefully, so you know what you’re covered for, before buying a water softener.

Bypass Valve, Area Available to House the Unit, and Other Considerations

  • A bypass valve is used to switch off the water supply to your water softener, while still allowing water to flow through your home’s pipes and into your appliances. It’s much easier to service a water softener with a bypass valve than one without.
  • If a water softener comes with a built-in bypass valve, it saves you the job of having to install a separate valve.
  • Once you’ve determined a location to store your water softener, you’ll need to make some careful measurements of the available space, and match this up to the water softeners you’re considering purchasing.
  • You might need to install a whole house filtration system as pre-treatment before your water softener if your water contains contaminants that could damage your softener’s mineral tank.
  • If you want to easily find parts for your water softener over the years, stick to systems with universal, not proprietary, components.
  • If a water softener is offering a new, revolutionary water treatment process, keep in mind that there might not be proof that it works. It’s best to buy a product that has a few years of positive customer feedback behind it.

💦 What is Hard Water?

Hard water is water that has a high mineral level. Water hardness can cause a number of issues in your home, which is why water softening solutions exist.

Water Hardness Map
source: usgs.gov

How Hardness is Measured

Typically, hardness is measured in concentrations of calcium and magnesium minerals in milligrams per liter (mg/L) which is the same as parts per million (PPM), or grains per gallon (GPG).

1 GPG = 17.1 mg/L = 17.1 PPM

water hardness scale

Determining your Water Hardness

You might know that your water is hard – but you need to know your exact water hardness to focus your search on water softeners that can handle your home’s hardness level.

To work out your water hardness level, you need to measure your water’s calcium levels. To reiterate the information from the hardness scale above:

Hardness ClassificationGrains/ gallonmG/L or PPM
Soft< 1< 17.1
Slightly Hard1 - 3.517. - 60
Moderately Hard3.5 - 760 - 120
Hard7 - 10120 - 180
Very Hard> 10>180

There are a few options for measuring hardness:

  1. Test your water using an at-home test kit (easy, less than $10)
  2. Get your water professionally tested by a laboratory (easy, costs around $50)
  3. Check your local authority’s latest Water Quality Report (easy, free, not applicable to private well owners)

Once you know how hard your water is, you can start looking for the best water softener systems to meet your softening requirements.

⚠️ Signs & Issues Caused by Hard Water

Use this quick checklist to work out whether you have hard water:

  • You’ve noticed a white or grey residue on your showerheads, faucets, bathtubs, sinks, kettle, and coffee maker.
  • Soap and shampoo don’t later well with your water.
  • Your pipes, plumbing system or appliances are damaged or leaking.
  • Your drinking water has a strong mineral taste.
  • Your laundry is stiff or stained with white spots.

These signs are indicators that you’re dealing with hard water problems, affecting your:

Hair & Skin

When you wash with hard water, hardness residue deposits a film that clogs pores and sticks to hair, aggravating conditions like eczema, dandruff, and acne. Hard water can also strip the moisture from the surface of the skin and hair, leading to dry skin and irritation.


You might notice that when you’ve washed your dishes in hard water, instead of looking clean and clear, they’re coated with a white, cloudy residue from the harsh minerals in the water that are left behind on their surface.

Faucets and Pipes

In particular, limescale deposits from hard water can damage your plumbing. The damage goes far beyond the kitchen and bathroom features we can see. Water passing through the pipes is dragged back by the limescale, reducing water flow.

Appliances & Water Heater

Over time, hard water running through your home’s appliances will start to cause damage. Your dishwasher may clean your dishes less effectively, and a build-up of hard water sediment in your gas water heater can affect its performance efficiency.


To clean your clothes properly, you’ll need to use almost twice the amount of detergent in a machine that uses hard water, compared to one that uses soft water.

💡 What Is A Water Softener?

A water softener is a type of water softening system that removes minerals like calcium and magnesium from water. These minerals are what make water “hard”, and can have an effect on the quality of water produced.

There are three main components in traditional salt-based water softeners:

  1. A brine tank: a large tank that contains salt, and fills with water to form brine
  2. A resin tank: the other tank containing the tank media, called a resin, where the water softening process takes place
  3. A digital control head or control valve: The digital control head uses touchpad controls and operates the softening system

🔡 What Are the Different Types of Water Softeners & How Do They Work?

There are a number of different whole-house water softener variations available on today’s market. Different types of water softeners use different components and techniques to remove calcium, magnesium, and other hard water minerals from water.

Salt Based Ion Exchange Water Softeners

The most common method of softening water takes place in an ion exchange system, where calcium and magnesium are removed from the water, replaced by sodium ions.

Salt based water softeners (also called ion exchange softeners) contain resin beads, which have a negative charge. The calcium and magnesium minerals in hard water have a positive charge, and because opposites attract, they move towards and pass through the resin beads, where ion exchange takes place.

During the ion exchange process, the calcium and magnesium minerals are trapped in the resin, and equal amounts of positively charged sodium ions are released into the water. By the time the water leaves the system, it’s completely free from hardness minerals.

Keep Reading: How ion exchange water softeners work


  • As the most heavy-duty water softener, a salt softener strips all hardness out of the water, leaving no magnesium and calcium minerals behind
  • Many salt water softeners are NSF/ANSI certified
  • Salt softeners offer a wider range of benefits aside from just reducing the build-up of scale on water-based appliances


  • Salt based water softeners tend to be more costly because of their efficiency in removing minerals from water
  • Not everyone wants to add salt into their water, even in small amounts, which you have to do with a salt softener
  • This type of system requires more maintenance than a water conditioner or electronic water softener that doesn’t use salt, and wastes water during the regeneration process
salt based water softeners

Salt-free Water Conditioners

Unlike salt-using softener systems, the best salt-free water softeners use a conditioning technique like template assisted crystallization (TAC) that changes the composition of hardness ions so that they’re no longer capable of depositing limescale onto a surface.

Salt free water softeners descale water instead of softening it. When water leaves the system, it still contains calcium and magnesium ions, and it doesn’t contain sodium ions. The big difference is that the hardness ions can’t form scale.

This study by experts at Arizona State University provides compelling evidence of the effectiveness of TAC.


  • Because the scale-causing minerals are not actually removed from water, you can still benefit from the nutritional value of these minerals with a salt-free system
  • A salt-free system tends to be lower-priced
  • Salt free softeners don’t usually require in-depth installation or maintenance, don’t require a regeneration cycle, and come with everything you need to get started
  • The best salt-free softener uses less electricity, is more environmentally friendly, and is suitable for people on a low salt diet


  • You may still notice issues with skin, hair, and laundry because salt-free softening isn’t quite as effective
  • A salt-free system can’t be used with well water sources
  • Unlike a salt-based heavy-duty water softener, a salt-free system won’t work well in areas where hardness is higher than 75 GPG

Electronic/ Magnetic Water Descalers

Magnetic water descalers, or electronic water softener units, are water softening systems that offer a chemical-free water softening process.

A powerful magnet on the outside of the system alters the magnesium and calcium ions in hard water, descaling the water before it enters the household plumbing system.


  • Electronic descalers are the most affordable salt-free softeners available
  • It’s easy to install this type of water softening system
  • You can use an electronic descaler as a portable water softener because it’s not permanently installed at your water line


  • There’s a lot we don’t know about the electromagnetic descaling process and its effectiveness
  • Unlike other salt-free softeners, magnetic water softeners are only useful for treating mildly or moderately hard water

Salt Based Softeners vs Salt-Free Water Conditioners

Salt-using softener systems and salt-free water descalers offer largely the same result: soft water. However, the water produced by a salt-free conditioner isn’t technically “soft”. It still contains magnesium and calcium carbonate, but these minerals are unable to form scale as they have been crystallized.

The water produced by traditional salt-based systems, on the other hand, has had its calcium and magnesium minerals removed, so is actually “soft”.

Product Variations

Dual Tank Water Softeners

A dual tank softener, otherwise known as a twin tank water softener, is a popular water softening solution for homes and businesses.

Dual tank water softeners are considered better than single tank softeners because they consist of 2 resin tanks, allowing for a higher water capacity.

When one tank needs to regenerate, the dual tank system automatically switches over to the second tank, preventing a lag in water production at any stage in the regeneration cycle.

Portable Water Softeners

Whether you need softened water for your RV, boat, spa, or anything else that might require water softening, you’ll be able to use portable water softeners to provide the results you’re after.

Usually, portable water softeners are smaller versions of single-tank salt-based water softeners and are designed for lower water consumption and water pressure.

Combination Water Softeners

For hard water that contains high quantities of iron, combination salt-based systems can filter out iron, magnesium and calcium particles using a softening process in just one system.

They are particularly useful for treating water that contains ferrous iron, which commonly causes rust stains. A fine mesh resin is used to trap ferrous iron, while a dedicated iron filter removes ferric iron.

Does Reverse Osmosis Remove Hard Water?

Reverse osmosis systems are capable of removing almost every impurity from water, and that includes magnesium and calcium minerals. However, it’s not a wise idea to install a reverse osmosis water filter system if you’re dealing with anything more than moderately hard water.

High water hardness can damage the reverse osmosis membrane and shorten its lifespan. It’s best to use a reverse osmosis system if you’re dealing with mild to moderate hardness. Or, use a reverse osmosis system in combination with a whole house water softener system – but install the softener first.

💵 What Factors Influence the Price of a Water Softener?

Water softener machines vary significantly in price, with the cheaper systems costing less than $500, and the more expensive models costing more than $2,000.

Some of the biggest factors influencing the upfront and long-term running costs of a water softener are as follows:

  • Installation and maintenance – you may need to pay for a professional installation, or you may need to pay to top your system up with salt.
  • Pre-filter – it’s essential to use a pre-filter to prolong the lifespan of your softener, but the frequency of filter replacements will determine the long-term running costs.
  • Brand – a well-known brand can give you guaranteed reliability, but at a cost. Top brands, such as Aquasana, Pelican, SpringWell, iSpring, and Fleck, all price their products higher than their lesser-known competitors.
  • Single tank or dual tank – single-tank salt-based systems are cheaper than dual-tank systems, but a dual-tank water softener will allow for consistent performance, even during regeneration.
  • Regeneration cycle – your long-term costs may be higher if your system performs a time-based regeneration cycle, as it may regenerate before it needs to, wasting more water and salt. Using a softener that follows a demand-initiated regeneration cycle will help you save money as the unit will only regenerate when needed.

✔️ Benefits of Using a Water Softening System

Using one of the best water softeners is the simplest way to eliminate hard water issues in your entire plumbing system.

Read on for some of the key benefits of using water softening systems.

  • Appliance longevity: The best water softener system can remove up to 99.9% of all hard water minerals from the gallons of water that you use on a daily basis, preventing the deterioration of appliances.
  • Improved water heating efficiency: Softened water systems eliminate limescale buildup in your heater’s heating elements, so they can more quickly and efficiently heat up water, helping you to cut down on heating bills.
  • Fast flow rate: Softened water contains no calcium minerals that typically cause mineral buildup. For this reason, it won’t leave a scale deposit on pipes that might slow down water flow.
  • More efficient cleaning: Soft water lathers with soap much more easily. You can save money on expensive powders and detergents for your washing machines, because you’ll be able to use fewer cleaners to get the same results.
  • Lime/ Stain-free Surfaces: With a water softener, you’ll save yourself hours of cleaning limescale deposits from surfaces that come into contact with your tap water.
  • Healthier Skin and Hair: Soft water balances your hair’s pH, helping it to maintain its moisture and smoothness. Soft water is beneficial to the skin for similar reasons – the sudsy lather produced with soft water will give skin and hair a better rinse.

🛠 How to Install Your Water Softener

To install a water softening system, here’s what you’ll need:

  • Pipe cutter
  • Flexible tubing
  • Torch/solder (optional, depending on your pipes)
  • Drain line
  • Air gap fitting
  • Tape measure
  • Plumber’s tape
  • Pliers
  • Fittings
  • Valves, adaptors, and tees

Step-by-step Installation Instructions

These step-by-step instructions show how to DIY install most traditional types of water softener systems:

  1. Find the best location for your water softener at your main water pipe, before your heater.
  2. Turn off your main water supply, and drain water from your pipes.
  3. Turn off your water heaters.
  4. Use a pipe cutter to cut into the main line where you want to position your water softener.
  5. Install an elbow fitting to feed water from the pipe into your filter.
  6. Use the compression fittings that come with the unit to attach the elbow fitting to your system.
  7. Attach the hose to the unit and clamp it in place. Check that it feeds to where water will drain.
  8. Attach the overflow tube to the salt or brine tank.
  9. Adjust your bypass valve to the bypass position and flush it with the recommended amount of water.
  10. Plug in your unit and return the valve to the backwash position. Slowly open the valve, allowing water to pass through bit-by-bit while freeing air from the pipes.
  11. Flush your water softening system’s resin bed as per your manufacturer’s instructions.

🔧 Maintaining Your Water Softener

Salt based softeners require simple maintenance to keep them working efficiently and help increase their lifespans.

The only maintenance task that’s required regularly is to add salt to the brine tank. Still, there are other, less frequent tasks that are needed to keep a whole house water softening system working for more than a decade, like:

  • Clean out your brine tank
  • Clean out your resin bed, especially if your water contains high iron or tannins levels
  • Clean the resin tank injector

👁‍🗨 Other Popular Whole House Water Softener Brands

When deciding on the best water softener systems for this list, we considered products from the following popular brands:


Clack has been selling water softening solutions since 1946. Clack is a lesser-known brand, largely because it doesn’t have many products to choose from, and the products that are available can be difficult to buy online.


Culligan provides a range of water softening, water filtration system models and water dispensing solutions. The biggest setback of Culligan is that you have to purchase its products through a Culligan rep, who will visit your house and tell you what products you need. You can’t buy products online, and you can’t easily compare Culligan’s prices to the prices of competitors on the market.

You can learn more about the cost of Culligan water softeners here.


GE is a big brand known for its home and kitchen appliances, including salt-based water softener systems. You can get GE softeners for an affordable price, but, because GE isn’t exclusively a water treatment brand, some of its products don’t quite live up to expectations. In short, there are better manufacturers that specialize in water treatment.


Founded in 1970, Kinetico manufactures traditional salt-based softeners, most of which don’t need electricity to operate. You can only buy from local dealers, who sell Kinetico softeners at a higher price and take a sizeable cut of the sale. You’ll need to put more work into finding a local distributor and spend more money in the process.


Morton is most recognizable as a table salt brand, but you can also buy salt-based softeners from this manufacturer. Morton’s water softener systems are better than average, but they’re not exceptional. You can’t buy Morton water softeners online, either. Instead, you’ll need to find out whether the water softener you’re interested in is available “at a store near you”.


Waterboss first started selling water softening systems in 1991. Although Waterboss sells good products, its products aren’t anything particularly exciting, and they’re not the easiest to come by, so they haven’t made this list. Check out our Waterboss review here.


Genesis softeners are salt-using units that are sold by Discount Water Softeners. While Genesis systems are manufactured in the US and offer a decent performance, their high price tag deterred us from featuring them in this guide.


Kenmore is a well-known kitchen appliance brand, selling dishwashers, refrigerators, microwaves, and more. We think Kenmore’s salt softeners are good, but their performance doesn’t blow us away.

❔ Frequently Asked Questions

Which water softener is best for home?

Depending on whether you prefer salt-based or salt-free softening, the SpringWell Futuresoft Salt-free Water Softener is the best conditioner, and the SpringWell Salt Based Water Softener System is the best salt-based softener.

What size water softener do I need for a family of 6?

It depends on your water hardness. If your hardness is only around 5-10 GPG, you’ll be fine with a 32,000 grain water softener. If your hardness is between 21 and 30 GPG, a 64,000 grain water softener will be more effective. You can contact the manufacturer to discuss your grain capacity requirements if you’re unsure.

How many years does a water softener last?

Most salt-based systems have a lifespan of 10-15 years. Salt-free systems last 10-20 years, or longer, depending on the type of system.

What makes one water softener better than another?

Value for money. If a water softener…

  • Uses less salt and water than others
  • Is made from more durable materials than others
  • Has a longer-lasting resin than others
  • Is more reliable than others

… and it’s still priced fairly, it’s superior to its competitors.

How much salt does a salt-based softener add to water?

You can expect the best salt-using softener to add between 20 and 40 milligrams of salt to soften water.

To put this into context, a single slice of white bread contains around 700 milligrams of salt. Unless you’re on a low sodium diet, your health won’t be affected by this relatively small addition of salt into your water.

Does my water bill increase with the use of a water softener?

It depends on what type of water softening system you buy. Installing a traditional water softener in your home means you’ll need to pay a slightly higher water bill. Your softener will need to flush out the calcium and magnesium ions that have built up in the resin tank from time to time, wasting water in the process. Water conditioners and electric water softeners won’t affect your water bill.

Can I use potassium chloride in place of salt in my softener?

Yes, you can use potassium chloride pellets in place of salt in a water softening system.

Potassium chloride is a good sodium alternative if you’re looking to watch your salt intake, or you’re on a low sodium diet.

Salt is more efficient at removing magnesium and calcium from water, so you should move your hardness setting up by 20% when using potassium chloride.
