The Springwell FutureSoft ranked the highest based on our review methodology, and for good reason. The technology built into the salt-free water softener provides 99.6% scale prevention. No chemicals or salt requirements ensure your water pressure never drops unexpectedly.
The salt-free Futuresoft water softening system wastes no water because it doesn’t have to regenerate. Therefore it never discharges harmful salt brine into the environment like with ion exchange.
Springwell FutureSoft salt-free water softeners process your home’s water via Template Assisted Crystallization (TAC). In this process, hard water minerals like calcium and magnesium are converted to a crystalline form.
Once the minerals are neutralized, they no longer stick to the plumbing, china, and glassware and keep your appliances and water heaters free of annoying scale and build-up. But what I especially like about this process is it removes even existing scale buildup, not just future scale.
So far I am positively surprised. We have pretty much no scale buildup in the sink, which we used to have before. We used to have extremely hard water. Also, I have not noticed any buildup elsewhere. I am very happy and would recommend.Andrew M. – Verified Buyer
The durable Springwell FutureSoft salt-free water softener system incorporates 20 years of water quality science and expertise and is manufactured using only premium NSF-certified components so it will last for years to come.
Since it comes in 3 configurations depending on the number of bathrooms your home has, you can get a tailor-fitted solution. This ensures optimal performance without overpaying for the capacity you don’t need. You can check the different specifications above.

The Evo utilizes the latest high-performance salt-free conditioning technology and is specifically designed for healthy water from every tap in your house without the negative effects of sodium and hard water scale.
The two-stage softener system starts with the 20-inch 5-micron sediment filter. This extra-large filter removes dirt, silt, and other debris to cleanse the water and help protect the salt-free softener cartridge in the next stage.
The proprietary eSoft salt-free cartridge uses Template Assisted Crystallization (TAC). Once hard water comes into contact with the eSoft media, the calcium and magnesium ions are altered so they are no longer able to stick to plumbing and appliances.
I installed the system and immediately lost the chlorine taste and odor along with the “musty”
smell. It descaled all my shower heads and no more water “spotting”.Richard S – Verified Buyer, Florida
The best part is you get all this without a drop in water pressure. The EVO has the capacity to support a house with up to six bathrooms and has a huge max flow rate of up to 15 gallons per minute.
What really sets the Evo apart from its tank-based competitors is its ease of use. This system can be installed in under 90 minutes thanks to its inline design. It only has two connections – water in, and water out. The included install kit comes with everything you need. And because it’s cartridge-based, it takes up no floor space.
Made in the USA with NSF-certified components, the EVO comes with a lifetime warranty and a 120-day guarantee.

The GreenWave salt-free water conditioner is the best eco-friendly system for the environmentally conscious. Unique patented Filtersorb SP 3 media and an industry-leading Vortech distributor plate work in tandem for long-lasting and efficient salt-free water conditioning.
Filtersorb SP 3 media uses Nucleation Assisted Crystallization (NAC). This process deactivates the hard water minerals, then converts them into harmless, microscopic crystals. Once suspended in the water, they can pass through the system and bypass your plumbing – offering your home clean, clear, softer water!
US Water softener systems focus on removing as much calcium and magnesium as possible by neutralizing minerals that adhere to surfaces and inside your home’s plumbing.
A water softening system to exceed your expectations, the GreenWave salt-free water softener allows water to pass through a pressure vessel, transforming the calcium bicarbonate into calcium crystals. As the NAC reaction occurs, the crystals filter away from your plumbing, allowing the fresh softened water to flow into your home.
Each US Water GreenWave salt-free water conditioner system includes a stainless steel tank, Vortech plate, media to eliminate clogging and build-up, a bypass valve, and an installation manual.
The single tank US Water GreenWave Salt-Free Water Conditioner measures 58.5” H x 9” W.

Crystal Quest Salt-Free Water Conditioner
Crystal Quest 4-stage salt-free water conditioner softens water using four unique filters. The key to perfectly conditioned water is the Crystal Quest’s ability to transform hard water minerals into mechanically stable and heat-resistant calcite crystals. Calcium is what creates scale in your pipes and faucets which leads to higher utility bills and frequent expensive appliance repairs. Scale can also be a breeding ground for bacteria in your drinking water.
Fortunately, the Crystal Quest Salt-free conditioner uses the latest technology to eradicate all these issues. Lime and calcium deposits simply rinse from the system. All that’s left is clear, fresh drinkable water with positive health benefits.
Stage one, a 20” sediment filter cartridge that removes sediment, silt, sand, and dirt. Stages two and three push water through the Crystal Quest Eagle Anti-Scale media tank, and a 20” solid carbon cartridge to remove volatile organic carbon compounds (VOCs), insecticides, pesticides, and industrial solvents.
In the fourth stage, a 20” 0.2-micron ultrafiltration (UF) membrane uses Crystal Quest purification technology to produce high-purity water quality for your home. UF removes colloids, bacteria, viruses, parasites, plus organic molecules larger than 0.2-micron.

Salt Free Water Softeners Buyer’s Guide 2023
More than 85% of the United States is affected by hard water issues, so it’s not a surprise if you’re battling water hardness in your home.
When searching for a saltless water softener system, there are key considerations to finding the ideal fit for your home. This guide will walk through everything you need to know to make an informed decision. Here we will discuss how a salt-free conditioner works, what to look for when deciding which model is best, and the pros and cons of a saltless softener.
How do salt-free water softeners work?
Salt free softeners work using a process called template-assisted crystallization (TAC). A recent study demonstrated that water softener alternatives using TAC are very effective in treating hard water issues . This report concluded that TAC was shown to reduce scale by more than 90%.
Template-assisted crystallization consists of a resin media tank where hard minerals (calcium and magnesium) are collected as water runs through it.
Crystallization of the minerals occurs within the resin at microscopic nucleation sites. The minerals are given a crystalline coating that keeps them suspended in the water. At this point, the crystals can no longer stick to surfaces and form scale.
Once a TAC salt-free water softener has been installed, further scale buildup in plumbing and fixtures will be prevented.
This is why they are commonly referred to as salt-free water conditioners because the TAC process does not remove minerals like in the salt-based ion exchange process.
Here are the key factors to consider when purchasing a saltless water softener for your home.
Understanding your water composition is critical in deciding the best salt-free softener. The levels of hardness, pH, calcium, magnesium, and sediment will determine which size softener you’ll need. There are two primary ways to understand your home’s water quality.
The first is Testing your home’s water with a test kit. Here you can purchase a DIY kit with test strips or can get a home lab water test. The DIY kits are quick and inexpensive but are not nearly as accurate as a home lab test kit. I would recommend the lab test kit as they are very accurate and cover dozens more variables than a DIY.
You can also check your local municipal water by checking the annual water quality reports they publish. Simply type in your zip code to see the contamination and hardness levels of the local water supply. The downside of this method is it doesn’t test your specific home, it is showing data from the water supplier. So, it’s a good starting point and it’s free.
Water Flow And Pressure
Singing your favorite tune in a relaxing hot shower can come to an abrupt and shocking halt when an unexpected blast of cold water releases itself through the showerhead. That means you have lousy water pressure. Once the faucet turns on in the kitchen or the washing machine is on, the rest of the faucets suffer.
Understanding the correct water pressure for your home keeps your pipes from bursting or your taps drying up. And you need efficient water pressure in the winter months to keep your lines from freezing.
But, nothing is more critical than water pressure on your whole home water conditioner and filtration systems. The Gallons Per Minute (GPM) flowing through the cartridges and filters determines how long they will last, which should be the manufacturer’s recommended six months or more. You’ll save tons of money, and your showers will stay hot from beginning to end!
Once you’ve determined your water flow and pressure, it’s good to tour your home and count your faucets, water-powered appliances, showerheads, toilets, and any other inflows.
Some water conditioners and filters use no electricity, while others require a dedicated outlet. You’ll need to determine the compatibility and the type of technology that works best for your home to rely consistently on your whole house water softener.
To DIY or not to DIY. Suppose you’re not a professional plumber and have no clue how to install a whole house water conditioner or filter.
If installation seems out of your wheelhouse, call around for a free estimate and when the plumber arrives, ask probing questions about the system you’ve purchased. Most of all, ask how much the installation will cost. You can expect to pay between $300 to $800 to have the softener system professionally installed. This depends on the system type and hourly rates.
If a maintenance-free whole house salt-free water conditioner sounds like a good fit for your home’s water conditioning needs, go that route first. Most systems need little more than a regular filter change and no additional water to run or clean. Most salt-free water conditioner system manufacturers use materials that can allow them to be installed inside or outside and face the elements.
If you want to commit to having time to maintain a whole-house salt-free water softening system, the good news is that you won’t be dragging heavy bags of salt home from the big-box garden centers. The bad news is you’ll be maintaining a system and not making a professional plumber’s wage.
We covered the warranty for each of the whole house salt-free conditioners we’ve reviewed. Most manufacturers offer a 3-6 month money-back guarantee at the time of purchase. That is in addition to a limited lifetime warranty. If the system comes with a warranty, make sure you fully understand what parts are covered and if the system can be returned when it kicks in.
Certifications & NSF Standards
Look for the NSF “seal of approval.” If you see it on your salt-free whole house water softener and conditioner system, you know it was rigorously tested by the respected leader of global independent product testing organizations.
It is easy to take the safety of your water, food, and consumer products for granted. The National Sanitation Foundation (NSF) ensures industry standards and safety regulations. The NSF holds companies accountable to these standards when producing the vast array of products we use daily.
Physical Space Available
When researching your whole house water conditioning system, you’ll discover that each model comes in varying sizes.
From a compact, wall-mountable 27″ L x 46″ H x 9″ D, like the Aquasana Salt-Free Water Conditioner, to taller individual vertical cylinders measuring several feet high.
Be sure to walk the perimeter of your house – inside and outside – and locate your home’s inlet where the filtered, conditioned water and the external water source meet. Take vertical and horizontal measurements, then shop for the salt-free water conditioning system that fits into the suitable space and your budget!
Cost Involved (Upfront Cost and Ongoing Maintenance Costs)
Some systems may have a higher upfront cost, but also a shorter replacement cycle. For example, the Aquasana has a 6-year life, while the SpringWell or Evo systems can last towards 10 years.
But the good news is since these systems are all salt free, they don’t require ongoing salt refills in a brine tank. The only ongoing maintenance is to replace any pre or post-filters that come with the systems which need to be done every 6 – 12 months. These typically cost about $30.
Don’t forget that the cost of your whole house salt-free water softener system may cost more if you’re treating well water and the water leans towards the hard side and doesn’t have a near-perfect pH balance.
You’ll save on your energy costs since most salt-free water conditioners don’t need electricity to condition your home’s water supply. And you’ll save a lot of money never buying bags of salt anymore!
Pros and Cons Of Salt Free Water Softeners
Salt-free softener alternatives are great innovations with a lot of benefits, however, there are some drawbacks to be aware of.
What Are The Benefits Of A Salt-free Water Softener?
- Removes scale buildup and longer-lasting appliances
- Require no drainage or regeneration, so no waste water
- Doesnt requrie salt or chemicals
- No sodium added to drinking water
- environmentally-safe product
- Requires no electricity
- Easy installation and maintenance free
- Retains healthy minerals in water
What Are The Negatives Of A Salt-Free Water Softener?
- Conditions water, so doesn’t remove magnesium and calcium like ion exchange
- Best to use pre-treatment if you have well water with heavy sediment or iron
- Can have a higher upfront price than traditional salt-based water softeners
In previous reviews we analyzed the Pentair Pelican Natursoft Salt Free Water Softener however, it did not make the list this year. The Pelican Natursoft water softener alternative was a good value, however, the products in our updated list proved to be more effective. Additionally, the Pelican Natursoft is becoming more difficult to service as less retailers have it available anymore. You can view our full video review of the Pelican softener from last year.
We also reviewed the NuvoH2O Manor Duo Water Softener + Taste Filter System in years past. The NuvoH2O system is unique in that it uses a CitraCharge process. However, the salt-free softeners on our list edged out the NuvoH2O Manor based on our review criteria. You can view our review video of the Nuvo here.
FAQs For Salt Free Conditioners
Do salt-free water softeners really work?
Yes! A process known as template-assisted crystallization can reduce or eliminate the negative effects of scale by up to 99.6%.
Which water softener is better, salt or no salt?
Salt-based water softeners altogether remove hard water minerals and do it well. As a result, they eliminate many of the problems associated with hard water.
Salt-free water conditioners use TAC or NAC to crystalize hard water minerals so they won’t stick to plumbing and appliances. In most cases, a saltless system will do the job. But if you have extremely hard water, an ion exchange system is preferred.
How long does a salt-free water softener last?
Most salt-free water softener manufacturers guarantee at least 6-year shelf life, but our top choices will last up to ten years. Read the fine print and warranty information to understand the value and lifespan of your salt-free whole house water softener.
Are salt-free water softeners more expensive?
The upfront cost for traditional softeners can be lower because there are so many options available. That said, saltless conditioners are not significantly more than salt-based options. Especially when you do the math over the lifetime of paying for salt and water in a salt-based system, salt-free can be less expensive.
The cost to install a saltless softener is typically less than a salt-based softener because you don’t have the extra brine tank to deal with.
Can you use a salt-free softener for well water?
Salt free water conditioners can work with well water, however, pre-treatment is recommended so the sediment doesn’t foul the softener media. In some cases, it may be best to use a water softener designed for well water if you have heavy iron or magnesium levels. A water softener is able to remove most of the minerals from the water which are present in excess thereby improving the taste as well as the quality of the well water and making it completely fit for human consumption.
Does a salt-free water softener filter water?
No, salt-free water softeners/conditioners are not water filters. They don’t use special media filtration and do not work to remove many of the harmful metals POCs and bacteria that a water filtration system is designed to do. So, adding a whole-house water filtration system combo with your salt-free water softener is a fantastic investment.
