6 Best Salt-Free Water Softeners of 2024 – Reviews & Top Picks

Hardless NG Lotus Whole House Water Filter and Water Conditioner

A salt-free water softener

Soft water has many benefits, but in the United States, 85% of homes are supplied with hard water. Many people turn to water softeners to solve this dilemma. Unfortunately, traditional water softening systems utilize large amounts of salt to remove the hard minerals from the water via an ion exchange process.

This requires monthly maintenance for regeneration and large purchases of salt. Moreover, it increases the sodium content in your water. For those with hypertension or other medical issues, the added sodium could be a real problem.

Don’t worry, there is a solution to getting soft water without adding sodium. Salt-free water softeners can still provide you with all the benefits of soft water without the monthly maintenance or added sodium content.

Your options are wide open, with many models available, which may present a new problem. To help solve this one, we’ve tested many of these salt-free systems to see which ones gave us the most delicious water devoid of scale and excessive mineral content. The following reviews will share what we’ve learned to help you decide which model is ideal for your home.

  • The 6 Best Salt-Free Water Softeners:

    1. Tier1 Eco Salt-Free Water Softener – Best Overall


    With flow rates of up to 7 gallons per minute to accommodate homes with up to six bathrooms, the Tier1 Eco Series Salt-Free Water Softener is an impressive unit that earned our admiration. It requires no electricity, no salt, and no backwashing. Once the system is installed, you only have to replace the filter cartridge every 2 months. Since it is a filter-based system, the Tier1 salt-free softener will filter out more than just the minerals causing hard water.

    You’ll see a reduction in chlorine, sediment, iron, and more. The resins inside that are responsible for softening the water will only last 3–5 years before needing to be replaced. We were very happy with the water produced by the Tier1 Eco Series. Our clothes, skin, and hair felt more nourished after a few days of washing in the softened water.

    The taste of the water was greatly improved, making it much more refreshing and pleasant. Hard water spots disappeared, and we were left with clear water straight from the tap. Overall, this is our choice of the best salt-free water softener available this year.

    • Up to 7 GPM flow rate
    • Filters out many contaminants
    • No backwash phase
    • Requires no electricity
    • Cartridge filter needs to be replaced every 2 months
    • Resins will only last 3-5 years

    2. YARNA Alternative Water Softener – Best Value


    There are two main problems that most people face when looking at water-softening systems. They can be expensive and difficult to install. SANIA has attempted to remedy these issues with the YARNA, which we think is the best salt-free water softener for the money. Compared to other systems, the YARNA is relatively affordable.

    Moreover, this device is much easier to install than most systems that require hooking directly into your main water line. The YARNA is installed on the outside of any pipe up to 2 inches in diameter. It then delivers electrical impulses to the water that change the structure of the mineral crystals, causing them to lose their bonding ability.

    Since it doesn’t remove the hard minerals, the YARNA isn’t a true water softener; it’s just a water conditioner. But it does prevent minerals from forming hard water spots and scale deposits, even though it doesn’t remove them. This means you get the benefits of soft water while still getting the essential minerals that traditional water softeners remove.

    • One of the more affordable systems
    • Prevents minerals from forming scale deposits
    • Easy install on any pipe up to 2”
    • Not a true water softener

    3. APEC Salt-Free Water Softener – Premium Choice

    APEC Water Systems

    For worry-free water that you can rely on, the APEC FUTURA-10 Whole House Salt-Free Water Softener is a premium product with a matching price tag. This is one case where we believe you get what you pay for. With an impressive flow rate of 10 gallons per minute, this device will have no problems providing adequate water to your home with no pressure drop. However, it’s only good for homes with water hardness levels below 25 grains per gallon.

    Within that range, this is an incredible system. This system is virtually maintenance-free, with no need for backwashing, electricity, or salt. A 10-year warranty protects it, so you can have peace of mind knowing you won’t have to worry about it leaving you high and dry. Most importantly, the water that it produces is excellent.

    We loved the crisp, refreshing taste, which was a great deterrent to hard water spots. There was no slimy feeling on the skin after showering, and our hair and skin felt great after a few days of washing in the water from the FUTURA-10.

    • Impressive 10 GPM flow rate
    • Maintenance-free
    • 10-year warranty
    • Safe for plants
    • Very expensive
    • Only suitable for water hardness levels below 25 grains/gallon

    4. OneFlow+ Salt-Free Water Filtration System

    OneFlow Salt-Free

    The OneFlow+ is an effective, low-maintenance salt-free scale prevention and water filtration system. With a max flow rate of 10 gallons per minute, it can easily handle the water needs of a whole house. Since it is a salt-free system, the OneFlow+ uses two cartridge-style filters to condition the water.

    The media cartridge prevents scale and removes the hard water minerals. It will last up to 250,000 gallons or 3 years. The second filter is a 20-micron carbon filter that removes sediments, chlorine, taste, and odor. It’s good for up to 50,000 gallons or one year of use.

    Since it doesn’t require any electricity, installation is relatively simple. It just requires one line in from your main water and then one line out to reconnect. There’s almost no maintenance, but we still aren’t wild about replacing two filters. The OneFlow+ is also one of the more expensive systems, though it offers no unique features. It’s a solid performer, but we prefer our top picks.

    • Cartridge lasts up to 3 years or 250,000 gallons
    • Requires no electricity
    • More expensive than similar systems
    • Two separate filters to replace

    5. Hardless Water Filter & Water Conditioner

    Hardless NG

    Since it’s more than just a water conditioner, the Hardless NG Lotus filters out sediments and bad flavors to leave you with a refreshing drinking experience, even if your tap water isn’t the best to start with. Unfortunately, it’s not a true water softener, so it isn’t removing the minerals that cause hard water.

    Instead, it changes the structure of the mineral crystals so that they can no longer bond together, eliminating scale deposits and other hard water problems. The NG Lotus uses no electricity and requires very little maintenance. It contains a single, five-stage filter that is easily replaced with no tools.

    When installed, this device doesn’t affect the water pressure in your home. We still had adequate flow to all fixtures, but the water was noticeably improved. Hard spots were gone, and the water tasted much better. However, we did have some problems with the unit leaking. The cartridge wouldn’t seal correctly when we first installed it. Luckily, it’s backed by a 4-year warranty, so we had no problems getting a replacement.

    • Doesn’t reduce water pressure
    • The 5-stage filter removes more than just hardness
    • Not a true water softener
    • Problems with leaks

    6. Eddy Electronic Water Softener Alternative


    Though it’s not a true water softener, the Eddy Electronic Water Descaler is one of the most affordable ways to get salt-free soft water in your home. It doesn’t remove the minerals from your water, but it prevents them from sticking together, which causes the hardness of the water.  To do this, the Eddy descaler requires electricity, making the installation considerably more difficult. You may even need a professional to do it for you.

    In our testing, the Eddy descaler did help to reduce hard water spots but didn’t eliminate them. They took longer to form, but they still appeared in time. We tried it in a home with high concentrations of iron in the water, but the Eddy wasn’t effective at removing the iron, and we still had discolored water. We appreciate the lifetime warranty that stands behind the Eddy descaler, but that’s not enough to redeem it. Despite the low price, we can’t recommend this device because it’s ineffective at softening water.

    • Very affordable
    • Lifetime warranty
    • Requires electricity
    • Descaler, not a softener
    • Did not eliminate scale
    • Doesn’t remove rust

    Buyer’s Guide – Choosing the Best Salt-Free Water Softener

    After reading the comparisons of our six favorite salt-free water softeners, you may have some questions that need to be answered. You probably noticed that there are some critical differences between these models. Some are installed on the outside of your water pipes, while others hook directly into the mainline of your home’s water.

    Some models filter the water as it passes through, and other devices merely condition the water. Moreover, you may be considering the benefits of a salt-free system over a traditional water softener. Is it a better bet? Why should you choose a salt-free softener instead? In this section, we will discuss all of this to ensure that you’re fully informed before you make a purchase.

    Benefits of Salt-Free Systems

    Traditional water softeners use salt to replace the excess calcium and magnesium molecules in your water with sodium molecules. This type of water treatment has been shown to remain effective for years, so why should you choose a salt-free system instead?

    Low maintenance

    Regular softeners require continual regeneration of the resins inside, resulting in weekly upkeep and maintenance. You’ll need to check the salt levels and add more regularly whenever needed. You’ll also need to flush the brine from the system. This upkeep can get tedious over time, but a salt-free system eliminates this issue.

    Many salt-free softeners don’t need maintenance at all. They will simply continue to condition your water without any input from you. Others will need occasional filter replacements, a simple process that takes little time, effort, or expense.

    No Added Sodium

    There are many reasons why you may limit or at least monitor your sodium intake. Water softeners increase the sodium content in your water, which can make a big impact on your sodium intake when you drink it every day. Salt-free softeners don’t add sodium to your water, so it’s much safer for individuals with hypertension, kidney disease, heart problems, and other health concerns.

    All the Benefits of Soft Water

    There are many benefits to soft water, and you may wonder if a salt-free system will still provide all of them. Though salt-free systems don’t remove the minerals completely, they neutralize them and prevent them from bonding. This means you’ll get all the benefits that soft water provides without stripping the water of essential minerals. The calcium and magnesium that water softeners remove are necessary for your health. This gives salt-free systems a leg up since they keep in these vital nutrients.

    What to Look for in a Salt-Free Water Softener

    Now that we’ve discussed the benefits of choosing a salt-free softener over a traditional one, let’s go over the differences between models that set them apart. Different methods of water conditioning and installation methods could make one preferable over the other.

    No Electricity

    Most of the salt-free water softeners that we tested didn’t require any electricity to run. Instead, they were simply powered by water pressure. We prefer this style since it won’t increase your energy usage. Also, running wires and hooking into your electricity can significantly complicate the installation process. If you have to call a professional, it will be much more expensive.

    How Often Do Filters Need to be Replaced

    Some models we tested featured filter cartridges that need to be replaced regularly. In some setups, these filters can last just 2 months, while they may last 1–3 years in other systems. For the least maintenance possible, use a system that only requires yearly cartridge replacements.

    Flow Rate

    Your water conditioning system needs to supply enough water for an entire house. If just one person is living in your home, this may not be a big deal. If you have a whole family under one roof, then your water needs may be greater. Be sure to get a unit that has adequate flow to supply your kitchen, all your bathrooms, and all of the people in the house. Some salt-free softeners have flow rates of 15 gallons per minute or higher.

    Ease of Installation

    If you need to call a professional to install your water softener, it will be considerably more expensive. Luckily, many of these systems are very easy to install, and most homeowners can do it themselves. On the other hand, some systems may require more complex plumbing or even electricity. Keep this in mind when choosing which water softener will provide your home with salt-free soft water

    Between our reviews and buyer’s guide, you’re probably ready to rid yourself of those pesky minerals and enjoy some salt-free soft water. Before you make a final purchase, we’ll review our top recommendations once more so that they’re fresh in your mind. Overall, the Tier1 Eco Series was the best salt-free water softener. More than just preventing the buildup of hard minerals, this softener will remove sediment, chlorine, bad taste and odors, and more. It provides enough water for an entire house and requires no maintenance or electricity.

    For the best value, we suggest checking out the YARNA Whole House Alternative Water Softener. It’s easy to install on any pipe up to 2 inches in diameter and effectively prevents minerals from forming scale deposits for an affordable price. Finally, if you don’t mind paying a premium for top-of-the-line performance, the APEC FUTURA-10 is a whole-house salt-free softener that does it all.
