Water hardness isn’t a health concern, but it definitely is a nuisance if the mineral concentration passes a certain threshold. Unfortunately, water from the majority of wells across the United States is affected.

Apart from ugly spotting, hard water leads to scale buildup in plumbing, fixtures, and appliances, and poor performance of soaps and detergents which can strain your skin and hair.

What to do about it? The most straightforward solution is to install a water softener. This buying guide provides a collection of the best ones for well water (we made sure to include systems that can handle well water containing iron). What’s more, you’ll learn what you need to look out for when shopping for your ideal system.

Best Water Softeners for Well Water

1. Our Top Pick: SpringWell SS

In our opinion, the best water softener for well water in 2020 is the SpringWell SS. The system comes in 3 sizes for different flow rates. The SS1 is for homes with 1-3 bathrooms. The SS4 for homes with 4-6 bathrooms. And the SS+ is for very large houses with 7+ bathrooms.

Most importantly, SpringWell SS water softeners eliminate hard water by removing calcium and other hardness minerals through ion exchange. The result: No more scaling in your plumbing system, water-using appliances, and fixtures for reduced maintenance requirements, fewer repairs, and an overall increased lifespan. Additional side effects include a higher efficiency of your water heater, no more ugly spotting on surfaces, and your hair, skin, and clothes will feel nice and soft, too.

On top of that, this is also the best water softener for iron removal (up to 3 ppm clear-water iron).

What does SpringWell do better compared to other salt-based water softeners? They combine metered regeneration with a Vortech resin tank to achieve supreme salt and water efficiency while regenerating, the digital control head is Bluetooth-compatible which allows for easy programming and monitoring, there’s a 6-month money-back guarantee and a lifetime warranty – and the list goes on. 5 stars!

3. Best Setup for Well Water with Iron Over 3 PPM: SpringWell WSSS Filter-Softener Combo

In our opinion, the best solution for softening well water with high iron content is to use a combo of the SpringWell SS water softener and the SpringWell WS whole house well water filter system.

We’ve already reviewed the SpringWell softener above. It’s salt-based and removes calcium and magnesium using ion exchange technology. Thus, pipes, home appliances, and fixtures are protected from scaling, meaning less maintenance, fewer repairs, and increased lifespan. Other benefits are no more limescale spots on surfaces, softer skin & hair, etc.

If you combine that with the SpringWell WS whole house well water filter which uses air injection with greensand filter media you get something powerful enough to deal with almost any iron contamination issue – filters out ferric + ferrous iron up to 10 ppm without problems. 5 stars!

4. #1 Water Conditioner for Well Water: SpringWell FutureSoft

If you’re not a big fan of water softeners that rely on salt to take care of water hardness you’ll like SpringWell’s FutureSoft salt-free water conditioner. If you ask us, it’s the best of its kind using Template Assisted Crystallization (TAC) to crystallize all minerals causing hard water so they remain suspended instead of attaching to surfaces.

This means that your water won’t be softened in the actual sense. It’ll still contain the same amount of calcium and magnesium. However, scaling is inhibited by as much as 99.6%. What’s more, already existing scale deposits will vanish with time – great for your home’s pipes, the water heater, the dishwasher, shower heads, and so on. And there’re more benefits which you’ll learn about below. 5 stars!

Important: If your well water contains noticeable levels of iron, manganese, hydrogen sulfide, or copper additional pre-filtration is required. We recommend the SpringWell WS whole house filter system as introduced on top. The filter-conditioner combination can be purchased here.

  • Requires pre-filtration if heavy metals or sulfur are present.

5. Cheapest Option: Tier1 Systems

In case you’re looking for a low-budget solution to your hard water problem, you should definitely consider a Tier1 water softener. They’re a “no-frills option”, which by the way doesn’t say anything about their effectiveness. It’s just that there’re a few trade-offs like lower regeneration efficiency and limited water flow when compared to the higher-priced models in this guide.

Which Tier1 should you go for? If you’re okay with a manual bypass valve which shuts off the water supply during regeneration process (about 2 hours), check out the Everyday/Essential series (see picture). They’re the most popular and the most affordable – coincidence? If, however, you’re willing to invest just a tiny bit more we recommend a Tier1 Advanced/Certified water softener which has a few nice extras.

  • Installation instructions could do with an overhaul.
  • System programming requires some getting used to.
  • Manual bypass of Essential water softeners shuts off water supply while regenerating.
    • Make sure to schedule regeneration cycle to kick in at night!

6. #1 Electronic Water Descaler for Well Water: Eddy

The Eddy Electronic is our number one water descaler in 2020 for both tap water and well water. It reduces hard water scaling with the help of electromagnetic waves. Sounds like bogus? It isn’t! The same study that proved Template Assisted Crystallization as used by the SpringWell FutureSoft to be effective also analyzed electromagnetic treatment. The result: It reduced scale formation by about 50%. Now, this is nowhere near perfect but the scientists also found that the remaining scale was “soft” and could be easily removed with the help of a brush. Add to that the small price tag of the Eddy Electronic water descaler and you get 4.5 stars from us!

Buying Guide: Choosing the Perfect Softener to Conquer Hard Well Water


There is no one-size-fits-all approach to softening hard well water. Sure, you always need a water softener or water conditioner, however, additional pre-filtration might be required.

For example: Well water that contains a lot of sediment should run through one or more sediment filter stages before it enters the water softener. Otherwise, the softener might clog up.

If your water is high in chlorine – think shock chlorination – you want to consider adding a carbon pre-filter which will protect the delicate softening resin.

In case of iron, manganese, and/or sulfur, a well water filter system might be necessary.

Bottom line: Have your water tested and, based on the results, make sure to have the right pre-filtration in place.

The Exception: Well Water with Ferrous Iron

Almost any standard salt-based water softener can be used to remove low amounts of ferrous (clear-water iron) from water. You usually achieve good results if the iron concentration doesn’t exceed 3 ppm – read the manufacturer specifications to double-check.

That said, it’s likely that the iron will eventually foul the resin beads. This is why it’s critical that you inspect the bed regularly. Also, more frequent regen cycles with longer backwashes and higher salt doses can delay fouling and increase the resin’s lifespan. The same goes for adding chemical iron removers (if done regularly). Once a resin bed has fouled beyond a certain point there’s no chance for recovery and replacement is the only option.

Water pH

Ferrous converts to ferric (red-water iron) more quickly in alkaline water (pH above 7). Thus, if the pH of your well water is too high a water softener is not the best choice for iron removal.

Ferric, Organic Iron & Iron Bacteria

You should not use a water softener to try to treat ferric, organic iron, or iron bacteria. For one, they may simply pass through the system totally unaffected or, even worse, lead to rapid clogging or fouling of the mineral bed which will render any water softener useless.

Water Softeners and Water Conditioners

Only systems that are salt-based are water softeners in the real sense. They make use of a process called “ion exchange” to remove hard minerals – mainly calcium and to some extend magnesium – from (well) water. All other types are water conditioners. They use different treatment methods like Template Assisted Crystallization or electromagnetism to reduce the scaling effects of hard water without actually removing anything from it.

Traditional salt water softeners have a long history and are still the industry standard today due to their very high effectiveness. But salt-free water conditioning systems are growing in popularity as they’re becoming more sophisticated delivering better results. Plus, they have many advantages such as oftentimes being more affordable, not adding extra salt to the water, and not requiring any backwashing or regeneration whatsoever.

Softening Capacity

Ion exchange water softeners must have a high enough capacity to be able to meet your soft water needs. The required capacity depends on 2 factors:

  1. Your individual water hardness level usually measured in grains per gallon (gpg).
  2. The average amount of water you use on a daily basis.

For example: Let’s say your well water is moderately hard containing 11 gpg of hardness minerals. And your family of four uses 320 gallons of water a day. This means your hypothetical water softener would have to remove 11 grains per gallon x 320 gallons of water per day = 3,520 hardness grains per day or 24,640 grains every week.

Now, the amount of hardness grains that a salt water softener can remove before it needs to regenerate (backwashing the resin beads to flush out all hardness minerals that have accumulated and replenishing it with sodium or potassium ions) equals its softening capacity. Capacities for whole house water softeners range from around 24,000 to 80,000 grains and even higher if need be.

Based on weekly regeneration cycle which is considered the optimum, the water softener from our above example should have a capacity of at least 40,000 grains in order to be able to handle both water hardness level and water consumption.

Why not go with 24,000 or 30,000 grains? Salt efficiency! Regenerating a water softener to 100% requires a disproportionately high amount of salt. Partial regeneration on the other hand is much more efficient. For comparison: Recharging no more than 40% of the softening bed may require ⅕ of the salt dose, whereas recharging 85% of the bed may require ⅗ of the salt.

Simply put, partially regenerating a larger system will save you a lot of money on salt in the long run. Higher salt efficiency also means discharging less salt into the environment or your sewage system which are nice additional benefits.

Water Flow Rate

If you live in big household with multiple bathrooms you need a water softener with a higher service flow rate. Measured in gallons per minute (gpm), a system’s flow rate determines how many showers and faucets etc. you can simultaneously use without seeing a water pressure drop or hard water bleeding through.

Typical Water Use of Modern Outlets & Appliances

  • Kitchen faucets: 1.5-2.0 gpm
  • Bathroom faucets: 1.0 gpm
  • Toilets: 3.0 gpf
  • Shower head: 2.0 – 2.5 gpm
  • Dishwashers: 6.0 – 16.0 gpl
  • Washing Machines: 25.0 gpl

For homes with one to three bathrooms we recommend a flow rate of 11 gpm or higher. Around 13 gpm should be sufficient for 4+ bathrooms.

NSF Certifications

NSF Standard 44 was established for cation exchange water softener systems. A certification substantiates a manufacturer’s performance claims with regard to

  • The effective reduction of calcium and magnesium, and possibly other hard water minerals
  • Salt efficiency (system must remove a minimum of 3,350 hardness grains per pound of salt)
  • Water efficiency (system must not waste more than 5 gallons of regenerant water per 1,000 hardness grains removed)
  • Material safety
  • Structural integrity


There are water softeners that cost a few hundred dollars and there are units that cost more than a thousand dollars. Going with the lowest price isn’t always the smartest decision. Cheaper systems often lack the efficiency that more expensive models provide which makes a huge difference long-term expenses (salt, water, sewer, repairs).

Other Considerations

  • Municipal regulations – Your local authority may have banned the use of ion exchange water softeners.
  • User-friendly digital control head – Allows for simple programming, monitoring, and troubleshooting.
  • Built-in bypass valve – Makes system installation a whole lot easier.
  • Separated or combined resin/brine tank – We prefer separated.
