Best Water Softener Reviews & Buyers Guide

You want the highest quality of water available for your family to drink, cook with, bathe with, and use for laundry and other household routines. Water that is “hard” contains minerals, usually calcium and magnesium, which can build up and leave deposits in your appliances, sinks, and tubs, or even in your plumbing.

While water is in the ground, it has a tendency to pick up little pieces of soluble matter, such as minerals that are found in the earth. Other matter may cause contamination when the water picks it up, but minerals such as magnesium chloride or calcium are not truly harmful to the body if ingested. However, they can be harmful to the pipes and appliances in your home.

As hard water is harder, cleaning agents may become less effective and can even cause a sticky residue when combined with the minerals. Dirt and other gunk can get trapped and begin clogging up pipes. Appliances such as dishwashers and washing machines may begin to work less effectively as soap can be deposited on dishes as well as keeping clothing from getting clean.

Scale buildup can be especially detrimental in reducing the efficiency of water heaters as they provide hot water to your home.

Hard water also may leave the skin feeling dry or itchy, leave water spots on your dishes, and also may require a significantly greater amount of soap in order to create suds.

So what’s the best way to fight hard water? With a water softener, of course!

How do Water Softeners Work?

When choosing a water softener, it is important that you understand how the unit works and to consider the cost of upkeep as you determine affordability and functionality. These appliances typically work by using a process of ion exchange, whereby the water is exchanging the pesky minerals that you don’t want in your water for something else—often sodium or potassium chloride.

Depending on the type you choose, water softeners may need to be maintained by adding salt or potassium chloride a couple of times a year. Otherwise, the upkeep is typically fairly minimal.

Types of Water Softeners

There are basically two categories of what are referred to as water softeners: salt-based and salt-free. Models that use salt are truly softening the water by removing the minerals, while salt-free models work by changing the minerals so that they do not stick.

Both types have pros and cons depending on what you are looking for in a softener, but here’s a basic run-down of how they work.

Salt Based Water Softeners

The most standard type of water softener typically uses the process of ion exchange to soften the water. Because minerals are what makes the water hard, a water softener will effectively trade the minerals for something else, such as sodium chloride (salt) or sometimes potassium.

How it Works

The main part of the water softener is the mineral tank which houses small beads of resin (polystyrene), which carry a negative charge. Because magnesium and calcium carry positive charges, the minerals attach themselves to the negatively charged beads.

When a saltwater brine solution is washed over the resin, the positively charged sodium ions push the calcium and magnesium ions out. Some softeners have a separate tank which houses the brine solution, while others may keep the two tanks together in one casing.

So the hard water moves through the mineral tank where the calcium and magnesium ions cling to the resin and are exchanged for sodium ions. Eventually, however, the resin beads become saturated with minerals and need to be removed. In this regeneration phase, water is reversed to clean the tank and flush out the dirt.

Then the sodium brine solution is pushed back through the tank, the sodium ions stick to the beads, and the calcium and magnesium are sent down the drain. The tank is then flushed, refilled, and ready to start again.

Salt-Based Softener Regeneration Process

The control system that determines the timing of regeneration works one of two ways. Originally regeneration always worked on an electric timer, usually set to regenerate at night when household water is least likely to be used.

Soft water is not available during the regeneration cycle. This may happen once a week, or 2-3 times per week, depending on the capacity of the unit, size of household, etc.

Another type of controller uses Demand Initiated Regeneration (DIR). This means that regeneration only happens as often as it is needed. Instead of gauging the amount of time, it determines the amount of water that has been sent through the system and then triggers regeneration.

Because this may happen at any time of day, this type of system often has a reserve tank to be able to provide soft water even during the regeneration process. Many people prefer this type of system because it does not use any more salt than necessary, and does not produce any more waste than necessary.

Salt-Free Water Softeners

Technically, in order to be a water softener, a unit must actually remove the minerals or “hardness” from the water. Units that do not use an ion exchange method should probably truly be referred to as water conditioners instead.

In the salt-free processes, minerals are not removed, but they change form so that they no longer stick to surfaces. This is more of a de-scaling process than an actual softening process.

How it Works

In these types of conditioners, the water is sent through a non-chemical process called Template Assisted Crystallization (TAC). Specially treated resin beads are used in the tank which create a change in the minerals, particularly calcium and magnesium.

The minerals remain in the water but they are neutralized and become more soluble: from an ionic form to a crystalline form. The crystals are so miniscule that they are simply washed away by the flow of water in your household.

This means that they do not adhere to surfaces such as pipes, appliances, and other surfaces—including your skin and hair.

Because this is a physical process, many of this style do not use electricity, there is no need for adding salt, and no dumping of waste water--making this a fairly eco-friendly option.

In addition, there is no need for a regeneration process so soft water is always available, any time of day or night. A salt-free unit may, however, require the use of replacement cartridges, depending on the particular type you choose.

Recommended Salt-Free Water Softeners:

Differences in the Results

People who are health conscious may prefer a water conditioner for the fact that the minerals are still in the water and that there is no additional consumption of sodium. In addition, water that is conditioned will not have the soft or “slippery” feeling of salt-treated water, which some people find preferable.

And because they are more eco-friendly, there are typically no community restrictions that keep individuals from using a salt-free conditioning unit.

Ultimately, the magic of a water softener or water conditioner is that the water goes into the unit one way, and comes out without all of the minerals sticking to everything. Which type of system is better depends completely on the needs and preferences of the individual household, how hard the water is to begin with, and what are the desired results.

Deciding Which to Buy

A water softener is a large purchase that you want to make well. Deciding which brand and model to buy can be difficult when considering all of the options that are available. In order to make the most intelligent and affordable choice for your family, you should have access to recommendations.

Rather than hearing from the companies about how great their products are, you may want to hear from actual customers who give the best water softener reviews—and that’s exactly where our recommendations come from!
