What You Should Look for in a Water Softener

When searching for what makes the best residential water softeners on the market, our research brought us to the qualities below. These are the criteria you should be familiar with when making a selection, and they’re also what we evaluated each product on.

Salt or Salt-Free

The first thing to consider when selecting your water softener is whether it’s a salt-based version with a tank, or a salt free water descaler (also called a conditioner).

The main difference between salt and salt-free versions is that salt versions use ion exchange to remove hardness-causing minerals, while salt free water softeners change the structure of the minerals so that they cause less scale.

Usually, if you have very hard water (over 7 GPG) it will be best to choose a salt-based unit with a tank because they directly remove hardness-causing minerals and will give you better results.

On the other hand, if your water is only somewhat or moderately hard – or if the salt free system is rated for high GPG – salt free water softeners are a great choice. Salt free systems require less maintenance, are more environmentally friendly, and do a good job of preventing scale.

Grain Capacity

If you’re purchasing a salt-based softener then it’s important to choose the right-sized grain capacity for your salt tank. The higher the grain capacity, the more soft water it can produce.

This is calculated based on the amount of water used each day in your house, your water hardness, any iron present, and how long the system goes between regeneration cycles.

You simply take the total GPG (grains per gallon) hardness of your water, add 5 GPG for each ppm of iron, multiply it by the amount of water used per day (each person uses about 80 gallons per day) and finally multiply that by the number of days between regeneration cycles.

Here’s the formula for water that has 8 GPG of hardness, 1 ppm of iron, and 3 people in the house with a 7 day regeneration cycle:

13 GPG (8+5) x 240 (80 gallons per day per person x people) x 7 (regeneration cycle)

The minimum grain capacity for the salt tank in this situation should be 21,840 grains in order to meet the needs of the household.

Crosslink % & Durability

In the salt water softener ion exchange process, the resin is the ion-exchange media used to soften the water. This resin usually consists of cross-linked styrene and divinylbenzene (DVB) molecules.

With a higher percentage of crosslinking, the media gets stronger and more durable to where it’s able to withstand oxidation and physical damage for a longer period of time.

Most softeners contain 8% crosslinks – which is pretty durable – but some even contain 10% crosslinks, which can help improve lifespan. Simply put, while 10% is ideal, look for at least 8%. The other thing to consider with durability is the kind of warranty the manufacturer offers on their system.


If the softener you are purchasing contains independent certification, that’s another plus. It’s not totally necessary because some of the smaller companies with good products simply don’t have the money to invest in third-party testing, but if a unit has been certified by NSF then it gives it an added level of credibility.

In water softening units, you are looking for the ANSI/NSF 44 certification standard which is specifically for cation-exchange water softeners or water softener systems that conduct the ion exchange process.

You can see our guide here for more information on certification criteria.


Lastly, considering the price of your water softener is always a deciding factor. Keep in mind that more expensive units may last longer and be less costly over the lifetime of the system, so make sure to factor in the lifetime cost and quality of the product.

Our top picks and most quality water softeners usually range between $800-$2000 where the units closer to the $2000 range have more features and higher capacity. This is for both salt free water conditioners and salt tank versions.

Our Top Water Softeners Reviewed

All of our top-rated water softener systems have received the highest ratings from consumers and industry experts, but there are still some significant differences between models.

Some models use salt, and others are salt free softeners. Some have pre-filters and other added benefits, while others are budget whole house water softening systems. Some units in this review are better for well water usage, and others are better for a municipal household water supply.

The following water softener reviews below go into more detail.

1. SpringWell FutureSoft- (Top Choice & Best Salt Free Water Softener)


We spent time conducting extensive research for this review and talking with customers of the SpringWell Futuresoft salt-free water softener filtration system. 

We determined that most customers noticed reduced hardness in their water and were able to dramatically extend the lifespan of their home appliances and pipes without using salt.

This water softener is priced well for its benefits, and the company and customer service are top-notch compared to other companies. 

Why This is Our Top Pick: 

  • For being a salt-free system, it works very well at conditioning water with up to 81 GPG hardness and preventing 99.6% of scale formation
  • This model maintains a flow rate of at least 12 gallons per minute (GPM)
  • With a life-long warranty backing it, you don’t have to worry about the durability of the system
  • While this product isn’t NSF certified, SpringWell has been providing great water solutions for over 20 years
  • At $1,400 this is one of the more pricey systems, but you’re sure to save at least that much with the increased energy efficiency and lifespan of your appliances

What’s Unique About This System: 

The SpringWell FutureSoft model appears in many reviews as the best salt-free water conditioner, and it’s quite different from others. Unlike salt-based water softeners, which use an ion exchange system to remove hard water minerals, the FutureSoft salt-free water conditioner uses a physical process known as Template Assisted Crystallization (TAC). 

This process converts the hardness-causing minerals in your water into calcite crystals that won’t build up as scale in your appliances, pipes, and water heater.

Fluidization is the key to forming the calcite crystals, and years of experience and thorough testing led SpringWell to design a tank that fluidizes the media bed better than any other design on the market. 

The proprietary Springwell Futuresoft salt-free media converts the water’s hardness to these crystals, which will not stick to anything even under extreme temperatures. This is achieved by the filter’s media and the fluidization working together.

Not to mention, this water softener doesn’t waste any water or discharge any salt brine into the environment. You still get the healthy mineralization in your water, but the ions are changed so that you receive 99.6% scale prevention without using chemicals or salt – and all with zero drops in water pressure!

Who It’s Best For:

If you’re looking for the best salt-less softener, then SpringWell FutureSoft is the ultimate product for the price.

Springwell also has one of the top-rated salt-based water softening systems if you’re looking for a highly recommended salt system. You can check out their whole house salt system here

6. AFW Iron Pro 2- (Salt-Based Softener & Iron Filter Combo)

AFW Iron Pro

The AFW Iron Pro 2 Combination water softener offers a salt water softener and iron filter.

It’s effective if you have both a high iron ppm and a water hardness issue. Put simply, it’s one of the best water softeners for iron removal on the market.

Why This is a Top Pick:

  • Excellent performance against iron and hardness up to 70 GPG

Main Features & Benefits:

The Iron Pro 2 Combination water softener is an alternate version of the Fleck water softener (5600sxt) with added iron filtration. The complete system includes the tank, control valve, fine mesh resin, and brine tank. 

Unfortunately, compared to other softeners, the Iron Pro 2 Combination water softener only has a 32,000 grain water softener capacity, which falls short of the typical 48,000 grain capacity in other softeners.

The Iron Pro 2 has the same high-quality digital control head that the 5600sxt whole house system has, which offers easy, on-demand regeneration cycling, LCD, and touchpad controls.

This system can remove up to eight ppm of iron while softening water for your whole home. The Iron Pro 2 water softener also comes with everything needed in the box for installation, including the brine tank, bypass valve, and simple DIY instructions. 

The only downside here is that it’s heavy at around 50 pounds, and most people may require assistance when trying to install.

Who It’s Best For:

The Iron Pro 2 water softener is best for someone looking for a whole house water softener system that also filters out iron at an affordable price.

It’s also ideal for smaller households as the grain capacity is smaller than the average water softener.

  • Contains digital head to monitor your softening cycles
  • Clean black appearance
  • Good bang for the buck


  • Heavy
  • Not easy to install

If you want the best electronic water softener with no mineral tank or chemicals, a budget solution is the iSpring ED2000 whole-house electronic water softener.

This is a whole-house electronic descaler rather than a conventional water softener. That means it transmits electromagnetic waves through your plumbing, which prevents mineral buildup and limescale from accumulating.

You can see our eddy electronic water descaler review here, which is the same type of product.

Other Whole House Water Softener Brands We Reviewed

When narrowing down our top 10 picks, we considered all of the water softening system brands on the market. Here are just a few of the other brands we considered before narrowing it down.


Clack is a company that has been operating in the water business since 1946. Their background is in resin molding and control bypass valve production. This means that their water softening systems have reasonable water control. The main issue with Clack’s products is that they only have a few options, and they are hard to purchase online. 

Clack mainly sells control bypass valves, accessories, tanks, water filters, and a few complete salt water softeners. You can see our comprehensive Clack review here.

Overall, Clack is a good brand, but they didn’t quite stack up to our picks above regarding technological features, price, and customer service.


Kinetico has been in the water business since 1970. They focus on just a traditional salt-based water softening system with a brine tank. They have five different series of softeners. 

The main benefit of Kinetico’s systems is that the majority run without electricity. Getting a Kinetico softener involves finding a local distributor, so they can be more of a hassle to purchase and install.

You can see our complete Kinetico review here.

Overall, Kinetico is a sufficient water softening brand. Still, they didn’t quite make our top 10 list due to the difficulty in purchasing and installation, lack of salt-free options, and overall customer service and brand reputation.


Culligan is another big name brand that provides much more than just softeners since they have been in the water business since 1936. Unfortunately, since they are such a big brand now, their customer service is not very good.

There are many mediocre and negative reviews on Amazon and other distributors for Culligan’s softening systems. They also aren’t very DIY friendly, and they require a Culligan technician most of the time to help set up and fix the products.

You can see our complete Culligan review here.

Overall, due to the poor customer service and reliance on Culligan technicians, they did not make our top 10 list.


GE is another mammoth home appliance brand that also makes a water softener. All of their softening systems are salt-based and require refilling the tank every month or so. 

The products are decent and priced affordably, but their inexperience in the water market and lack of specialized customer service was a big deal-breaker. One of the other top brands recommended above would be a much better pick due to the specialization in water technology and innovation in the industry. 

GE simply hasn’t focused on making superior water softening products since they have so many other appliances on the market.

Morton has been in the salt business for a long time. They have sold salt to many different industries, and you probably recognize their name due to their regular table salt.

It makes sense that they would also produce a few water softeners which use their salt. Morton has many salt-based softeners that are decent – but nothing special. The primary issue with Morton softening appliances is their customer service and innovation. 

When you purchase a Morton product, you will have to deal with a “factory trained rep,” which can be frustrating when installing or troubleshooting your device. Also, Morton’s softeners are pretty middle-of-the-line with no outstanding capabilities. That is why they didn’t measure up for us.

Waterboss are whole house softening units made in the USA.

They are very basic ion exchange units that are inexpensive. The 900 model is a decent model but it’s not going to be one of the top products on the market.

A Buyer’s Guide to Water Softeners and Water Conditioners

Choosing your optimal home water softener requires understanding what a water softener is and how it works.

 It is also essential to know the results you can expect when installing a water softener system.

What Is a Water Softener?


A softener system turns the water entering your home “soft” by exchanging the minerals that cause hard water (calcium and magnesium) for sodium ions (salt-based system), or by changing their structure to make them unable to stick to pipe and appliance surfaces (salt-free system).

Both methods prevent limescale buildup in the home’s pipes and other issues that come from having hard water.

A typical salt-based water softening system contains two tanks (also known as dual tank water softeners).

These tanks include a tall resin tank where the ion exchange occurs, and an attached brine tank that works to flush the resin tank and add salt to the system.

Most systems also include an LCD screen and automatic monitoring to notify you of how much salt is left.

Water softeners are usually installed in the garage or cabinet close to your home’s incoming water supply so that the water can run through it. 

Simply put, your incoming water flow goes through your water softener tank, where there are resin beads that attract calcium and magnesium ions and exchange them for sodium ions – which effectively removes the water’s hardness. 

The softened water without these ions continues through your home’s water flow giving you clean, soft water. 

You can see our detailed guide on how water softeners work here

The only maintenance you will have to do with a water softener is refilling it with salt or potassium chloride pellets (if you’re using a salt system) when it runs out.

It’s also necessary to check the tank, making sure it’s regenerating the resin beads properly. After a while it may make sense to replace the water softener resin but owners usually only have to add salt to their system about once a month.

What Does a Quality Water Softener Remove?

A salt-based water softener removes calcium and magnesium, whereas salt-less softeners don’t remove anything. Instead, they change the minerals’ forms to reduce scale buildup. 

Also important to note, a water softener does not remove sediment and other contaminants from your water unless it comes with an additional sediment or carbon water filter.

A softener combo system containing a water filter can remove both hardness-causing minerals and other harmful contaminants like bacteria, heavy metals, herbicides, pesticides, and more.

Classification of Hard Water vs Soft Water

Water with at least 60 milligrams of hardness, causing minerals in every liter, is defined as moderately hard water. In some areas, these minerals’ levels are far higher than the minimum. For example, they could be as much as 180 milligrams per liter.

Another way to define hard water is by the number of grains per gallon (GPG) of calcium carbonate in the water. Water with more than 7 grains per gallon (GPG) is hard water, whereas between 3.5 and 7 GPG is moderately hard water.

On the other hand, soft water has only low levels of minerals — between 0 and 3.5 GPG. This level of hardness is far more desirable for multiple reasons. It can be healthier, it feels more pleasant on the skin, and it keeps your appliances and pipes protected from limescale buildup.

Grains/GallonmG/L or PPMHardness Classification
Less than 1Less than 17.1Soft
1-3.517.1-60Slightly Hard
3.5-760-120Moderately Hard
Over 10Over 180Very Hard
1 GPG = 17.1 mg/L = 17.1 ppm

Signs You Have Hard Water 

To determine whether you need a water softener, review the potential signs that your home receives hard water. These include:

  • If the water produces residue on dishes, faucets, bathroom fixtures, and any surface that the water touches, including on the bottom of your kettle and coffee maker
  • A blocked shower head
  • Dry skin or even residue on your skin after showering
  • Leaking or damaged water pipes, plumbing system, and appliances
  • Stiff, discolored laundry, maybe with white spots
  • A drop in water pressure
  • A lack of lather from soap and shampoo

You can also get your water tested to find out precisely what is in your water. Purchasing an online test kit or stopping by your local hardware store is a good option. That will help you determine if just a softener is best or if a combination softener and whole house water filter product would be ideal. 

See our guide on water softeners vs. water filters for more information.

The Problems With Hard Water

We discussed some of the main signs of hard water but let’s go into detail about why they can become problematic.

1. Pipes and Appliances Can Accumulate Scale and Lose Efficiency

If hard water causes limescale buildup on your pipes or appliances (like a water heater or shower faucet) this can cause leaking, lowered effectiveness, and a rotten appearance.

If these appliances aren’t working optimally you will be wasting energy, money, and time over the long run as well as run the risk of having to replace them sooner.

2. Can Cause Staining & Less Effective Cleaning Capability

Hard water can cause white spots on your dishes, staining in your toilets, and lower the cleaning capability of your washing machine.

3. Can Cause Skin Irritation

Hard water can contribute to dry skin, itching, acne, as well as causing dry scalp and other problems with your skin.

4. Water Taste and Clarity Can Become Murky

Although it has been shown that hard water doesn’t cause health problems in the body (the minerals can actually be beneficial for you) it can make your water taste metallic and cause a cloudy appearance.

Benefits of Soft Water

If you have hard water, a water softener will provide you soft water with a large number of benefits.

1. Prevent Limescale Damage

Damage from the residue of hard water can be as severe as internal damage to your plumbing system, which can cause pipes to become clogged or start leaking. With a whole-house water softener, you’ll prevent the scale and white limestone leading to this damage.

2. Improve Appliance Efficiency

It requires more energy to heat hard water than softened water. Also, appliances and pipes become less efficient over time as scale accumulates.

Tank water heaters are at exceptionally high risk, as they hold water for hours on end. Having said that, even a tankless water heater will have a shorter lifespan when they deal with hard water – and they require cleaning twice as often.

3. Avoid Stains

Hard water stains everything it contacts. You may notice discoloration on places like faucets, sinks, toilet bowls, your bathtub, and showerheads.

Spots may also appear on items you wash, including dishes, glassware, clothing, and even your car. If there is a large amount of iron in your water, the stains may be yellow, orange, pink, or red. When you have a water softener, these stains disappear instantly.

4. Use Less Soap

It’s often possible to remove stains left by hard water – it just requires a good deal of scrubbing and a large amount of soap. Softened water allows you to avoid this task altogether.

You’ll also need less soap in general – for everything from laundry to dishes. That is because soap doesn’t lather appropriately with hard water. When you have softer water, you’ll find that you’re able to clean much more efficiently.

5. Improve Your Skin and Hair

A healthy balance of minerals in your water can be optimal for your skin and hair, but an abundance of hardness-causing minerals can lead to damage. The minerals strip your body of its natural oils, leaving your skin and hair too clean and, as a result, dry.

Your hair may also be greasy, heavy, and lack natural buoyancy, and your scalp may be dry and flaky. If you dye or highlight your hair, the color will fade sooner. If your hard water also contains a high chlorine level, the water may even change your hair color, tinting it green or orange.

Having water without hard minerals is essential for people who suffer from skin conditions like eczema and psoriasis. Once you have a water softener, you’ll notice less irritation, and you’ll be less likely to suffer from razor burns.

6. Soften Your Laundry

Hard water minerals cause clothes and towels to come out of the washing machine stiff and scratchy. As soon as you have a water softener, the texture of your laundry will improve.

7. Enhance the Flavor of Your Cooking

It’s not just drinking water with a better taste – softer water impacts the flavors of anything you cook with water. You’ll also have better-tasting hot beverages like coffee and tea.

The Different Types of Water Softeners

As you will have noticed from the list above, there are many types of water softeners. There are the traditional salt-based systems and newer water softener alternatives.

Salt-Based Water Softeners

Water Softeners

Conventional water softening systems use salt. Sometimes, they are called ion exchange softeners after the water softening process.

The minerals that cause hard water exchange for sodium ions from the resin bed. The system traps the hard minerals in the resin and then flushes them out during its regeneration process (the cleaning part of the process).

Salt softeners are highly effective, but owners have to add new salt every month, and the type of water they produce contains added sodium and generates more wastewater.

If you purchase a salt softener for your home and you need to purchase water softener salt. We put together a guide on the best water softener salts here.

Dual Tank Water Softeners

Some salt-based types of water softeners have a pair of tanks. These are considered dual-tank softeners and are suitable for commercial settings and homes requiring a large amount of water.

With single-tank softener systems, there are times when you’ll be unable to receive soft water because the resin in the tank is regenerating. Usually, this occurs during the night, although it may occur after the system has processed many gallons of water.

With a dual tank water softener, you’ll never run out of soft water. During the regeneration cycle of one tank, the other tank can operate. This feature comes with a higher upfront cost, but you may decide it is worthwhile for homes with high water treatment needs.

Salt-Free Water Softeners


Salt-less softeners are a more modern alternative. Instead of using salt, they use a template assisted crystallization (TAC) process to reshape hard minerals.

The process turns minerals that are causing hard water into crystals that cannot adhere to surfaces. They work to prevent scale buildup instead of specifically removing the hard minerals.

See our water conditioner vs softener comparison here for more information.

Magnetic Water Descalers

One type of salt-free softener is the magnetic water descaler. Instead of using the TAC process, electromagnetism keeps water free from scale.

Although there are fewer magnetic water softeners on the market than other water softeners, they are gaining popularity for their simple water softener installation.

Instead of connecting the system to your water source, you coil wires around the water intake plumbing and then plugs into the system.

Like with the TAC process, the water descaler’s magnetic field turns minerals into larger crystals to prevent limescale accumulation.

See our water descaler vs softener comparison here for more information.

Salt-Based vs Salt-Free Softening Systems

Technically, only a salt-based system is a water softener in the most real sense.

Those that use a process other than salt are considered water conditioners. Either option has its share of advantages and disadvantages.

Water softeners are more popular, which means you have a large amount of choice regarding products. However, softeners require more maintenance than salt-less conditioners, which are virtually maintenance free. Salt based softeners also need to be connected to an electrical outlet, and they do waste water during the regeneration cycle.

Water conditioners or salt-less systems allow you to gain the benefits of soft water without adding any sodium to your water. They also cost less to maintain and usually require no electricity. These characteristics have helped them gain market share, and they are now available from many top manufacturers of water softeners.

However, as calcium and magnesium will still be present in your water with a water conditioner, it is not genuinely soft. If you were to run a test on the water, it would still come back as hard. So although water conditioners are often called softeners, they do not genuinely create soften water.

If you want to minimize the amount of sodium in your diet, be more environmentally friendly, and conduct less water softener maintenance on your system then a salt-free version is a good option to consider as long as you don’t have super hard water.

On the other hand, if you have very hard water and want the most effective softening system that has been proven through time, consider a traditional salt softening system.

You can view just our top salt-free water softeners here.

Does Reverse Osmosis Remove Hard Water?

softening system

Yes, reverse osmosis filtration will remove minerals from your water including calcium and magnesium preventing scale build up like water softeners do.

Most minerals in water are physically larger than water molecules and so they are trapped by the semi-permeable membrane and removed from drinking water when filtered through RO.

The main reason reverse osmosis is not usually used in place of a water softener for the whole house is because of the efficiency and price of the machine compared to a water softener.

For example, a whole house reverse osmosis machine usually runs in the $4,000 to $10,000 range while a water softener is around $1,000.

Also, a standard RO unit is usually used just for kitchen drinking water and not for the whole house, while a water softener is usually used as a whole house machine.

This is because reverse osmosis takes much longer to filter water and is more wasteful compared to a water softener.

If you have hard water we recommend installing a water softener for your whole house at the point of entry. Then if you want to add additional drinking water filtration combine that with an under sink reverse osmosis unit or a combo filter and softener unit for the most comprehensive solution.

Are Water Softeners Easy to Install?

Provided you have some DIY knowledge; you’ll find that most water softener machines are simple enough to install on your own. However, if you’re unsure when reading the manual, it’s better to call a professional.

All systems are easy to maintain without assistance. At the very most, they require refilling with salt every few weeks or months and changing pre-water filters periodically (between six months and six years, depending on the model).

How to Choose a Water Softener for Your Home

Let’s walk through the basic steps in choosing the correct water softener for your home.

Besides these steps, one other thing to consider is if there are any water softener bans or regulations in your area.

1. Hardness of Your Water

You’ve already figured out that your water is hard – but you need to know how hard exactly so you can choose the correct grain capacity.

A professional test will tell you the exact grains per gallon of scale causing minerals and what contaminants the water contains. That is also useful for knowing if you also require a water filter for your drinking water and need a combo system.

You can get a professional lab test done or purchase a kit online.

Another option is to ask your city for a report (this is not possible if your water comes from a well), check the documents from your home inspection (if you purchased your property recently), or look at a water hardness map for your area.

Below is a general water hardness map of the US to determine what level of hardness your water may be classified under:

2. Determine What Type of System

If you find that you have extremely hard water, you should only consider salt-based systems.

However, if you have moderately-hardened water, a system that does not use salt may be just as effective. In this case, what you choose will come down to personal preference. For example, if you enjoy soft water’s slippery feel, you may want a salt-based system. If a more significant priority is keeping sodium out of your water, a salt-free system is better.

3. Determine the Correct Size of the Water Softener

If you opt for a salt-based water softener, you’ll need to pick the right size. As mentioned above, to calculate the precise capacity, you’ll first need to know the hardness of your water. Note: if there is iron in your water, add five GPG for every part per million for a better picture of hardness.

Also, you’ll need to have an idea of your daily consumption of water. You can find this on your municipal water bill – or you can assume that each person in your household uses around 80 gallons a day. Once you know these numbers, multiply grains per gallon by the number of gallons you use per day. That tells you how many grains per day your system needs to remove.

Finally, you need to consider the regeneration cycle.

Ideally, your water softener will regenerate once a week. Therefore, you need to multiply the above number by seven. That tells you the minimum grain capacity of your water softener.

For instance, let’s say your water has 8 grains per gallon plus one part per million of iron, and you use 240 gallons of water a day (typical for a family of three).

Here’s the sample calculation:

Water with 13 GPG (8+5) x 240 (80 x 3) x 7 = 21,840

You’ll need a water softener with a capacity of at least 21,840 grains.

What Determines The Price of a Water Softener?

Water softener costs range from as low as $500 to as high as $2,500. Salt-based systems cost a further $5 to $10 for salt – and are even more expensive if you use potassium instead of sodium. They also waste around three gallons of water a minute in regeneration.

Other factors that influence price are additional features of the system. Some water softeners have just the necessary features you need to soften water and nothing else. Others have extras that could be worth the higher cost.

  • Brand – When you buy a softener from a well-known brand, you can be sure that you’re receiving a reliable system. Top brands include SpringWell, Fleck, Quality Water, Aquasana, Pelican, and iSpring.
  • Ease of maintenance and installation – Decide whether you are willing to put in the time to maintain a salt-based system. Think about your DIY skills. For example, do you care more about an easy water softener installation, or would you instead hire a plumber for the job?
  • Pre-filter – These water filters will remove some contaminants from your water, but you’ll need to pay regularly for replacement water filters.
  • Bypass valve – Only some softener systems come with a bypass valve. That allows you to bypass the softener when you don’t need soft water. It’s useful for tasks that don’t require soft water, like filling a swimming pool.
  • Regeneration setting – Regeneration can be preset or on-demand. Softeners with preset regeneration rely on an accurate estimation of water usage. For example, if you underestimate, the system will be inefficient. However, if you overestimate, you’ll sometimes receive hard water minerals. Demand-initiated regeneration, in contrast, suffers from neither of these problems. The system monitors when the resin is full of minerals and regenerates automatically.
  • One-piece or two-piece – If you have extensive water needs, consider a dual-tank system. However, if you have a small household, you’ll prevent wasted salt by choosing a single-tank softener.

Around 85 percent of households in the U.S. receive water that contains high levels of calcium carbonate, magnesium, and iron. However, only roughly a third are currently using a water softener. If your water is even moderately hard, you’ll benefit from a water softener. If it is very hard (10.5 GPG or higher), you should consider a water softener a necessity.

If the price is a significant issue for you, you can always consider a water softener rental, although we recommend purchasing if you will be in your house for a while to save money in the long run.

So, Which Water Softener Do We Recommend? 

After reviewing all of the best water softeners on the market, there are few choices we recommend.

If you are looking for our top recommendation and want a whole-house, saltless softener, then Springwell’s FutureSoft is your best water softener system choice.

If you want the best salt-based option for the money and have very hard water, you can’t go wrong with the Fleck 5600sxt model or Springwell’s salt model.

Lastly, if you want the best combination salt-free softener and filtration system,  Aquasana’s EQ-1000 Rhino is the best choice.

Keep in mind that a quality whole house water softener is a solid investment in your home, the home’s pipes, your health, and your home’s appliances – so don’t cut corners on quality.
