2. Powermag Magnetic Water Conditioner: Best for the Money
The Powermag Magnetic Water Conditioner is an easy to install solution for smaller spaces like mobile homes, apartments, condos, or RV’s. This piece is considered a “small” basic model, so if you don’t require extensive water filtration, this could be a good choice.
Using the most recent 360° surround hydro-magnetic technology, this conditioner can run without salt. The powerful neodymium magnets—that are a hundred times stronger than ceramic magnets—can be installed by anyone, without specialized tools or having to modify your home water pipe setup.

4. Salt-Free Water Softener Anti-Scale System: Whole House
The Salt-Free Water Softener Anti-Scale System is a whole house system, and we consider it one of the best salt free water softener systems. The 4-stage filtration process utilizes revolutionary technology, eliminating water hardness without the use of salt.
The built-in technology converts the calcium found in water into nano-meter-sized calcite crystals, incapable of causing lime deposits.
Composed of 3 20” filter cartridges, this system offers superior-high-quality results. The solid carbon cartridge removes all traces of volatile organic carbon compounds (and contaminants like pesticides, insecticides, and other industrial solvents).
The final stage involves a 0.2-micron Ultrafiltration membrane. This ultra-fine filter removes all remaining unwanted substances from the water, substances which require ultra-filtration to be removed. Some of these are parasites, bacteria, proteins, viruses, and endotoxins.
This system operates at temperatures between 40-100°F and pressures between 20 psi-125 psi. The tank itself is constructed from Fiberglass with a stainless steel and polyresin jacket.
This model is available in 2 different sizes. Select the option that suits yourself and your family’s needs: The 10” x 54” tank or the 12” x 52” tank. There is a 20 lbs. difference between these 2 options.
This conditioner also acts as a descaling device. Simply by attaching the device to your household's water system, you’ll benefit from its descaling power; removing old residue as well as preventing future build-up. After it eliminates this residue, a 30- to 80-micron thick corrosion-preventing layer forms thanks to the interaction between the pipe's metallic surface and the crystal's nano surface.
If you've had enough of dealing with water softeners which require salt, or if you live somewhere where they aren’t suitable, this salt-free Water Softener Anti-Scale System is a GREAT choice.
5. APEC Water Systems FUTURA-15 Premium: Premium Conditioner
The APEC Whole House Water Softener is a premium piece of equipment. Select the kind of softener you need based on the type of coverage required for your household. This model is also available with a coat and flagship WH filter, or standard WH filter.
This particular model is designed for use with 3-6 bathrooms—providing good coverage for a large house. This water softener is suitable for water hardness levels below 25 grains per gallon.
The APEC water softener utilizes a completely SAFE and NATURAL process to purify your household water. This softener uses advanced ceramic media to attract and neutralize hard water.
By converting the inherent water minerals into a scale-resistant crystalline form, you get great-tasting water with no lime deposits.
The compact single tank can be easily connected to the main water supply line, doesn’t require any electricity, and doesn’t waste water while it runs. This softener’s salt-free nature means it doesn’t reduce water hardness levels and is non-corrosive to pipes and appliances.
The APEC showcases quality that is rarely seen these days. This brand is designed, engineered, and assembled in the USA, giving it the unequivocal Made in the U.S.A stamp. Quality isn’t compromised with this company; they use supreme quality material based on 20 years of experience and research.
Be reassured by the 10-year limited warranty and additional expert support. This water softener is an investment but only requires a one-time upfront payment. After that, it maintains itself and saves you money in the long-term.
6. Yarna CWD24 Water Descaler: Electro-Magnetic
The Yarna Capacitive Water Descaling System follows earlier Yarna models, building on their structural foundation while blazing a new trail.
If the other Yarna models don't provide the coverage you need, this piece will. Choose the model that suits your pipe requirements. The 2-inch pipe diameter option, OR four-inch diameter. This is a significant jump from other similar models, which only cater to smaller pipe diameters.
Yarna focuses on specific functions: Sanitizing your pipes, reducing scaling, and preventing corrosion and rust. It does this through powerful electric fields that alter how calcium crystals behave within the water. When water flows through your pipes, passing through the 2 impulse coils, Yarna’s powerful electric waves change the water quality.
These impulse coils are made from customized isolated copper, with a high alloy purity. These firmly attach to your water pipe because of the flexible, thin construction. The flat coils increase the contact area, allowing for an efficient energy transfer.
You can expect up to 15.4 gallons per minute, or 3,500 liters per hour, of treated water to pass through the system with 99% efficiency. This is a cost-efficient, chemical-free, eco-friendly solution to virtually any household water system.
Similar to other electro-magnetic descalers, the Yarna is easy to install; specialist tools aren’t required, and it’s easy to maintain. For successful installation, all you need is physical access to your water pipe and at least ten-inches of pipe space to attach the copper coils.
Try this descaler risk-free for a whole year, with a 100% money-back guarantee.
7. Aquasana OPTIMH2O: UV Treatment
The OPTIMH2O is another high-quality option from Aquasana. This GROUNDBREAKING whole house filter system removes more than 99% of cysts and lead, 98% of PFOS/PFOA, as well as other unwanted substances.
Aquasana doesn’t make empty claims; it backs its data up with rigorous testing, official certifications, and ongoing research. The OPTIMH2O is IAPMO-tested and certified to NSF/ANSI Standard 53 and NSF/ANSI Standard P473. This means they have been confirmed to remove PFOA, PFOS, lead, and cysts effectively.
The OPTIMH2O utilizes powerful UV filtration to sterilize water, eliminating as many unwanted impurities as possible. Enjoy odor-free, deliciously-clean drinking water thanks to the combined action of the sediment pre-filter, carbon block, and salt-free water conditioner.
The hi-tech LED system indicator shows you how the system operates and if a filter change is required. Green indicates good water flow and no need for a filter change, yellow indicates the upcoming need for a filter change, red indicates the filter must be changed now. This color-coded system takes the guesswork out of your next filter change.
When you do need to change your filter, simply lift it out of the tank. No specialist tools are required thanks to the patented snap ring technology; easily lift and replace the filter. On average, a 20” pre-filter lasts 3-6 months before needing to be replaced.
This filter has an 8-gallon per minute flow rate, making this an excellent choice for the everyday family. This may be one of the more expensive water softening systems, but the results can more than justify the price.
8. HQUA 5000-E Rust-Preventive
The HQUA 5000E Electronic Water Descaler is a water softener alternative that utilizes new technology to address hard water issues. If you’re looking to minimize, prevent, and eliminate calcium deposits and stains, this descaler can help you reach your goal.
Any area touched by water, faucets in the bathroom, the inside of pipes, metal heating equipment, tubing, any area which comes in contact with water can be improved with the HQUA 5000E.
The easy installation makes this convenient and suitable for a wide range of people. Install this piece of equipment yourself, using no fancy tools or elaborate techniques. Attach the coil to any kind of pipe, so long as it’s no bigger than 1.5”.
The control box measures 6” x 3.5” x 1.5” and is easy to mount on the wall, or other surface, thanks to the 4 included self-adhesive pads.
Requiring just 4W of energy to run, the HQUA 5000E is a cost-efficient way to improve your household’s water quality. Not only this, the construction of this piece of equipment makes it a low-maintenance option for those who don’t want to trouble themselves with upkeep.
The HQUA 5000E sends an electromagnetic frequency-modulated wave into the water pipe through 2 cable bands. This frequency dissolves the calcium carbonate through the scientific principle of “resonance.”
This fundamental change to the water means calcium won’t stick to any surfaces; it doesn't have that ability anymore; instead, it stays within the water.
Although this doesn’t soften water, it comes with a cheaper price point and offers a number of benefits found in more expensive water softeners.
9. Eddy Electronic Water Descaler
The Eddy Electronic Water Descaler is a water softener alternative with a 12 month 100% money-back guarantee. This company wants to deliver the best; this is clear from the additional service policies and guarantees. Not only do you have a year to try out this water softener—or your money back—it comes with a lifetime replace or repair warranty.
This piece of equipment is capable of descaling your entire water system. Simply by introducing a complex electromagnetic wave into the water, limescale's adhesion properties are changed so it can’t stick to surfaces like it usually would.
Two coils are wound around your incoming water supply pipe, suitably-sized for pipes up to 1.5 inches in diameter. If you require larger coils for a larger pipe, you can purchase additional Eddy coil sets. These coils can be used with any kind of water pipe, except with iron or lead.
This descaler doesn’t influence the chemical hardness of the water. Yet, the electro-magnetic action will help loosen mineral deposits in your pipes, improving the overall condition and efficiency of your plumbing.
Installation is easy with this descaler; you don’t need to disrupt your entire water system or invest in expensive pieces of equipment. This is an environmentally friendly option which will benefit all the water which enters your household.
If you’ve had trouble with stubborn limescale deposits, then the Eddy Descaler is a cost-efficient way of managing the issue. Simply place the control box on the wall and plug it into a regular 110-volt outlet.
10. Aquasana Well Water Filter
The Aquasana Whole House Well Water Filter System removes 99.9% of harmful bacteria and contaminants from your well water. It also removes 97% of chlorine.
Remove common contaminants such as herbicides, pesticides, sediment, rust, water-soluble heavy metals, silt, and industrial solvent. This 500,000-gallon premium rhino whole house filter is built to last an average of 5 years.
This is a TOP-QUALITY water filtration system, which, similar to Aquasana’s other models, utilizes an efficient dual-tank upflow design. This construction allows for superior contaminant absorption, keeping the water in contact with the inbuilt contaminant-stripping material. The carbon media is specific for use with well water and provides optimal purification.
Using SCM technology—Scale Control Media—this silver system conditions your water without salt. This technology changes the structure of hard minerals, so they cannot adhere to surfaces; this reduces scale and buildup.
Enjoy the cost-efficient nature of this filter system, using less than $0.01 per gallon. This is twice as much as other brands. This system requires some low-grade maintenance; simply replace the filter every 1-3 months.
When you buy the Whole House Well Water Filter System, you’ll get your 500,000-gallon filtration dual-tank, a 20” pre-filter, post-filter, salt-free water conditioner, UV (with bulb), bend supports, a shut-off valve, and brass fittings.
This water filter is an efficient system for those who want to invest in a long-term option. Despite the initial investment, once this system is up and running, it operates without requiring much upkeep and doesn’t need money to continue to run.
11. Hardless NG3 Whole House Water Conditioner Compact
The Hardless NG3 offers a salt-free softener alternative for the everyday average household. This is the last of the whole house salt-free water softener reviews in our list, yet it packs a lot into a small space.
The 5-stage thorough filtering and conditioning system ensures unwanted contaminants are removed from the water entering your house. Taste the difference with the Hardless NG3, and improve the longevity of your water-run household appliances.
This system is composed of the til rod, cartridge, mesh filter, post filter, magnetic band, and the optional jet or valve. By passing through each of these filtering defenses, the Hardless NG3 is capable of producing superior-tasting water.
The cartridge used in stage 2 features slow phosphate crystals, altering the mineral structure and preventing mineral buildup within the pipes. From here, the subsequent stages further purify the water through the use of a 25-micron stainless steel filter and a 2-micron filter. This is topped by the water passing through a magnetic band.
This softener alternative strictly adheres to IAPMO and NSF safety standards, making this a safe and effective machine.
To get the best from this piece, it’s recommended you clean the water filter once a month. This can be easily achieved by unscrewing the in-line water conditioner valve and rinsing out any dirt or residue. Then, you’ll need to change the cartridge and filter every 6 months.
This conditioning system leaves beneficial minerals in the water. It does not affect TDS—total dissolved solids—readings, and so a TDS/ppm test will not accurately reflect the water quality.
The Hardless NG3 is one of the cheaper water softener options in this list. It offers a compact, easy to install, space-saving solution for those who want better household water.
We all know how vital water is to our health, but we can fail to consider how water quality matters. It doesn’t matter if we drink the right water amount if that very water is full of health-compromising contaminants. Salt-Free Water Softeners offer a solution to this problem. Once you install a water softener onto your household water supply, you can now access superior quality water.
The SoftPro Elite Salt Free Water Softener is the ultimate water purification system. It includes all the features you would need in a convenient, efficient, and health-promoting water softener.
