Best Salt Free Water Softeners Buyer’s Guide 2022

At the top of this Best Salt-Free Water Softener System Reviews (AKA Saltless, Salt-Free Conditioner) buyer’s guide and product review, we asked if you’d ever helped yourself to a drink from the tap been horrified by the aroma and appearance of your tap water.

If the answer is yes, and you’ve come this far into our buyer’s guide, and you’re still in need of clear, refreshing, tap water, free of harmful minerals and awful rotten egg smell, the answer is simple: it all starts with your home’s water quality. But what defines water “quality”? First, you test the water, and then you examine the results.

Water Quality

Testing your home’s water is easy. You contact your local water municipality or buy a water testing kit or both! Understanding your water composition – hardness, pH, levels of bacteria, metals, and sediment – helps you determine how much filtration you’ll need. 

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 col water releases itself through the showerhead. That means you have lousy water pressure. Once the faucet turns on in the kitchen, 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!

System Technology

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; at least Google how to install the system and read the instructions before you begin.

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. Some reviews we’ve read state consumers paid upwards of $400-600. You don’t know what you don’t know, so ask yourself, what is my budget? 

It’s better to know upfront what you want to spend than cheat yourself out of the water conditioning system you want because you need to pay a professional or get caught off guard with a plumber’s bill you can’t afford when you realize you have no DIY skills.


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 but be warned: most manufacturers only offer a 6-9 month money-back guarantee at the time of purchase. 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)

The cost of installing your whole house salt-free water softening system varies depending on the cost of the system itself. Do you want to go big? Go big! But, before you break the bank, test your home’s water and consult with a professional to understand what will work best for your square footage. 

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!


How do salt-free water softeners work?

A saltless water softener uses potassium in place of sodium. The potassium produces a chemical transformation that crystallizes the mineral buildup. This is useful in that it prevents the minerals from clinging to your plumbing, laundry, and other surfaces that hard water can develop scale on.

Do salt-free water softeners really work?

Yes! In a process known as ion exchange salt-free water conditioners (softeners) exchange the sodium ions in your home’s water supply by displacing the calcium and magnesium ions that create hard water.

What are the benefits of a salt-free water softener? 

You can expect reduced scale buildup and longer-lasting appliances. Salt-free water softeners are virtually low maintenance, easy to install, and require no drainage or regeneration. That equates to an environmentally-safe product. In addition, salt-free water softeners don’t use electricity and cost nothing to operate, which means significant savings on your monthly energy bill. 

What are the negatives of a salt-free water softener?

Remember, a salt-free water “softener” is a water conditioner. Water conditioners remove unwanted smells and tastes in your home’s water. They don’t filter the water.

If you can’t get a handle on a blanched pH, hard water spots will continue to appear on your glasses and dishes, and soap-scum buildup will persist on your shower doors.

You’ll ultimately waste money and up to 75% more on soaps, detergents, and shampoos. And your water heating expenses could increase by 30 percent.

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 ion exchange to capture and replace the harmful minerals but may not necessarily tackle any or all of your home’s hard water issues.

How long does a salt-free water softener last?

Most salt-free water softener manufacturers guarantee 6-year shelf life. Be sure to contact customer support if you have questions. 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 cost of installing a salt-free water conditioner is relatively low, considering there are usually no electrical or elaborate plumbing connections involved. Not having to lug heavy bags of salt from the big-box hardware stores saves time and money, and you don’t have to schedule maintenance or system flushes and refills.

Can you use a salt-free softener for well water?

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. This method is cheaper and safer than boiling water every time you need it for drinking or cooking

sulfur, manganese, iron, tannins

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 to your salt-free water softener is a fantastic investment. 

Final Thoughts on Buying a Salt-Free Water Softener System

Water sources vary, but the living bacteria, VOCs, and hard minerals and metals live in groundwater and well water. They accumulate over time along with that nasty sulfur bacteria we referenced at the top of our buyer’s guide. And while this occurs naturally, mainly due to decay and chemical reactions between the soil and rocks. When it enters your home’s plumbing, it needs to be conditioned as soon as possible.

If sulfur is the culprit flowing into your faucets, there is a good chance hard water is flowing in from your water source as well. Treating your home’s water with a salt-free water softener (conditioner) is an excellent first step in filtering out what you don’t want to drink and having confidence that every drink from the tap is healthy and, most importantly, “egg-free.”
