This water descaler descales the complete water system. It can be easily attached to any metal or plastic pipelines having a 1.5-inch diameter. The unit uses two coils that get directly connected to the pipeline and produce electromagnetic waves to pass the water through a magnetic field.

Each sleeve comes with six powerful neodymium magnets that create the magnetic field within the water to treat the calcium deposits. You can easily attach the unit with the incoming water line to turn the hardness into softness.

But if the incoming water is very hard, then it is better to don’t rely only on this magnetic technology.

This unit combines the commercial-grade water conditioning with carbon black filtration to filter various harmful pollutants and make the water free from minerals that cause hardness and scale buildup.

But various users have complained that the filtration capacity is not great. It doesn’t filter 40,000 gallons of water. Also, it reduces some pressure.

It doesn’t use salt to make your water soft. It reduces scale build-up by conditioning the water naturally.

The water softener features a SLOW PHOS technology that changes the ionic charge of the hard minerals. And due to this change in the ionic charge, these minerals get less attracted towards each other. Thus, scale build-up prevention becomes possible.

It has an operating pressure range of 20 psi to 100 psi.

But if we talk about its drawbacks, then it also doesn’t give the mentioned 50,000 gallons per filter cartridge. Also, it is not for big homes, and its installation is not stress-free.

Buyer’s Guide

APEC Portable Countertop Reverse Osmosis Water Filter System

It is not easy to select the best salt-free water softener without knowing anything about it. Some people just rely on the reviews and the description of the seller, but it is not the right practice. You must have to consider various things before purchasing your ideal product. So, what are those things, take a look.

Type of Salt-Free Water Softeners

First, of all, it is necessary for every buyer to know about different types of salt-free water softeners.

Whole House Water Filters with Salt-free Softener

These type of filters called full filters as they not only make the water soft but also filter out various harmful contaminants from the tap water. They coat and crystallize the calcium and magnesium grains to prevent them from sticking to other surfaces and pipelines.

These filters + water softeners also remove chlorine, chloramine, bacteria, viruses, sediment, rust, herbicides, and pesticides. They also eliminate the bad smell and make the water look good in taste.

Water Softener with Polyphosphates

Those water softening systems that filter water with the help of polyphosphates are quite simple. They are only designed to make water soft. They neither remove chlorine from water nor treat iron, sulfur, bacteria, herbicides, and pesticides.

These polyphosphates are very safe to use. They travel with water and coat the mineral grains so that they won’t stick to the plumbing systems. First, the filter removes larger particles from the water and passes the calcium and magnesium ions to the polyphosphate coating material.

Electro-Magnetic Water Softeners

These electromagnetic water softeners or descaling systems make the water soft with the help of electromagnetic waves. These units feature two coils that are responsible for generating electromagnetic waves within your water pipes. These coils get directly attached to the metal or plastic pipelines to create an electromagnetic field. And when the water passes through that field, the present mineral grains get magnetized and suspended.

They require a constant power source to prevent scale build-up. They don’t reduce the TDS levels. Also, they are quite easy to install.

Magnetic Water Softening Units/Sleeves

Magnetic units are different from the electromagnetic water softeners as they don’t require electricity to make the water free from mineral grains. Instead, strong magnets get directly attached to the pipes to suspend the water minerals. These magnetic units are not quite useful in making the water soft, and therefore, it is suggested to use them as the final stage of water filtration. They don’t require any maintenance as last for long.

Grain Rating/GPG

Grain rating is another thing that you must look at before purchasing a salt-free water softener. Grain rating determines how useful the water softener is to filter out the minerals or how long it will last.

So, first, it is necessary to know the GPG rating of your water and then find the right product according to that rating.

Filter Life

The filtering systems that also feature water softeners use filters that need cartridge replacement after filtering the mentioned amount of water. So, it is necessary to look at the filter life of your water softener to purchase the best product that can filter more gallons of water with a single cartridge.

Aquasana whole house water filter that comes with a salt-free descaler can filter up to 1,000,000 gallons of water whereas some filters can filter from 20,000 gallons to 50,000 gallons of water with a single cartridge.

Flow Rate

Flow rate is also very much important when looking for a salt-free water softener. Some water softeners limit the water flow, such as in-line water softeners. Therefore, it is necessary to go for a unit that offers a good flow rate.

Installation Process

Everyone wants to have a water softener that can be installed easily. So, you should also prefer those units that offer hassle-free installation.
