11 Best Salt Free Water Softeners – Reviews & Buyer’s Guide

OneFlow + Salt-Free Scale Prevention and Water Filtration System is known for its excellent performance and compact design. A Template Assisted Crystallization (TAC) feature helps to convert the hard minerals into harmless particles, resulting in filtered water for your household.

Some of the primary features of this water softener are:

Template Assisted Crystallization (TAC) Technology

This unique technology attracts and converts the hard minerals into harmless, inactive soft scale particles that stay suspended in water and flow freely through a system rather than sticking to pipes. This technology doesn’t add or remove anything from water, allowing useful minerals such as calcium, potassium, and magnesium to remain in the water. 

Scale Prevention

The OneFlow cartridge is used for the prevention of scale build-up which can last up to 250,000 gallons. The cartridge is used in combination with a 20-micron radial flow Carbon Block for the reduction of sediments, chlorine taste and odor for up to 50,000 gallons. 

Improved Appliance Efficiency

As the water flows through the Scale Prevention Cartridge, particles that cause scale build-up are prevented from sticking to the pipes. This assists to improve the plumbing system water flow and helps extend the life of appliances. 

Great-Tasting Water

The integrated high-capacity radial flow carbon block filter cartridge comes with a 20-micron rating. It filters both sediment and chlorine taste and odor. As a result, you get great-tasting water at every tap. 

Nature-Friendly

As the softening system comes with zero wastewater to drain, OneFlow + Salt-Free Scale Prevention and Water Filtration System is the nature-friendly solution. 

Easy to Install

The water softener is compact in design and comes with a standard one-inch NPT inlet/outlet adapters. It doesn’t require access to a drain or an electrical outlet. The system is simple to install, either on the floor or mounted to a wall with the included mounting bracket.

Stage 2: Here, the cartridge contains slow phos crystals, that change the structure of the minerals to prevent limescale buildup. 

Stage 3: Now, the conditioned water sprays through a 25-micron stainless steel mesh filter. 

Stage 4: In this process, the water goes through an additional 2-micron filtration process to clean water. 

Stage 5: In this final stage, the magnets in the outer band further condition the water while the previous stages are taking place. 

Small and Compact

One of the main features of this water filtration system is that it comes in small size when compared to many other models. At just 4.89 pounds, this one unit filters and conditions the water for your whole house, ensuring high-quality drinking water.

Design

The main feature of this water softener is the way it is designed. It is engineered as actually an electronic device and not a cartridge. The system has coils that are perfectly coiled around your piping. 

Working Mechanism

Eddy Water Descaler Electronic Water Softener uses an electromagnetic wave that interacts with the water. This field then passes through the incoming water and helps to stop limescale from sticking and depositing into the pipes. This system emulates the softened water and avoids the build-up inside your faucets and pipes. 

Easy Installation

The installation of this water softener is very easy. You don’t need wrenches or nails, just a mounting bracket will do the job. The process doesn’t require plumbing as you can plug the machine and attach it to a wall or let it rest somewhere safe. Make sure you coil the wires around the pipe properly.

The major features of this water softener are:

Hard Water Crystallization

Now let’s have a look at some of the key features of the Triple Action Poly Salt-Free Water Softener. 

Use of Polyphosphates

The system makes use of polyphosphates. This peculiar feature makes it different from a conventional water softener. It doesn’t remove hard grains from your water; instead, it crystallizes and coats the grains in polyphosphates so they don’t stick to your pipes, sinks, hair, and clothes. The polyphosphates are used in city water treatment facilities and they pose no risk to your health, your appliances, or your plumbing.  

Excellent Flow Rate

This water softener has an excellent flow rate. It comes with a 30-micron filter to catch sediment and it provides 30 gallons of softened water per minute. The flow rate is sufficient to cater to even a large family. 

Easy Refilling

You should fill the hard water bullet with polyphosphates every 6 to 12 months. Thankfully, the refilling task is easy with this softening system. All you need to do is turn the water off and empty the water line before unscrewing the lid and pouring in the polyphosphates.  

Great Design

This Poly water softener is engineered to be efficient and durable. In order to maintain it, turn your water valve off, run a faucet until the line is empty and unscrew the softener’s lid. After that, remove the filter and rinse it in a washtub while you flush the core with a vinegar solution.

Here are some of the major features of the Clearwave CW-125 Electronic Conditioner:

Electromagnetic Technology

This water softener works on the principle of electromagnetism. After the system is properly installed and activated, it generates an electromagnetic field. The field is then transmitted through the piping system and once the water runs through it, its adhesive property is altered. Eventually, the major minerals that cause hardness of water lose their abilities to stick to the pipes.

Excellent Flow Rate

Another excellent feature of this water softener is that it has a flow rate of 28 gallons per minute. The flow rate is sufficient for even a large family.

Environment-Friendly

Easy Maintenance

Since the product never uses salt, polyphosphates, or filters, it doesn’t require any maintenance work. It operates purely on the principles of electromagnetism.
