Before discussing and doing the water softener vs water conditioner comparison let’s look at what they are individually.

What is a Water Softener?

A water softener works through the elimination of water hardness by eliminating minerals (mainly magnesium and calcium) in water through a process called ion exchange.

Salt-based water softeners contain a resin bed that filters water through them and exchanges these minerals for hardness against sodium particles.

When the resin bed reaches a saturation point, the cleaning (or regeneration) cycle begins in which a series of back washes flush out the trapped minerals and expel them out of the system. The sodium particles are also replenished and the system continues to soften.

The result of this is soft water that will not create limescale or cause problems (like corrosion) for your home appliances.

What is a Water Conditioner?

A salt-free water conditioner does not soften water. It simply makes its minerals loose so that they lose their ability to stick to your pipes and plumbing. Some water softeners with no salt or saltless conditioners work better than others.

Types of Water Conditioners

  • Carbon Filtration.
  • Electromagnetic or magnetic water conditioners.
  • Salt-free Water Softener

Carbon Filtration

GAC (granular activated carbon) or carbon filters remove harmful bacteria. As well as contaminants by absorbing (or trapping) these compounds (e.g. organic compounds) that are attracted to carbon.

The main use of carbon filters is that they remove unpleasant odors or weird tastes from the water. For instance, sulfur in well water or chlorine in city water.

These systems are simple water purifiers for consumption and not water softeners. They do not soften the water by eliminating the hardness caused by minerals. Carbon Filtration is most commonly found in water filter jugs that are sold in supermarkets and in the water dispenser of your refrigerator.

Electromagnetic or magnetic water conditioners

Magnetic or electromagnetic water conditioners use magnets to create a molecular motion in the water.

This molecular agitation causes the minerals to displace, thereby reducing the concentration of calcium and magnesium ions. The result of this is that you are left with water that is effectively soft water in the sense that it’s less likely to make limescale.

Although not expensive, the performance of these devices are not completely guaranteed.

Also, the magnetic field is only present in the immediate area of where it sits on the device. This means that it can not treat large volumes of water at the same time and the water can only stay in the “soft” state for about 48 hours after the treatment.

Salt-free Water Softener

Optimh2o Reverse Osmosis + ClaryumCatalytic media conditioners, also known as salt free water softeners, don’t use ion exchange to eliminate minerals of hardness like their traditional salt-based counterparts.

Instead, water is treated through a catalytic medium that uses a physical process that is known as TAC (Template Assisted Crystallization).

This makes the shape of the minerals change into hard crystals that do not stick to the surfaces. However, the important thing to note is that these systems do not “soften” water, but simply condition it.

Water Softener Vs Water Conditioner?

A water softener is a specific type of water conditioner that reduces water hardness. Hard water is formed when dissolved calcium or magnesium ions are present in the tap water of a house.Getting a water softener means that it will remove all the “hard minerals” from your water at source.

On the other hand, a water conditioner is just a generic term for any sort of water system that is able to alter the quality of your water to improve it in some way.

Different types of water treatment units have different abilities.

Especially when it comes to water filtration in the ability to remove things like water chlorine. The main purpose is to remove all impurities and improve the taste of water – not just soften.

Water Softener Vs Water Conditioner?

The short answer is that it depends on your needs.

Mr Water Geek ThinkingIf you want to soften water at home or at your business premise, but are looking for alternatives to getting a regular water softener then you need a water softener alternative. However, the hardness levels below are a good rule of thumb to know which one is best. In order to get your GPG level you should get a water hardness test kit.

Optimh2o Reverse Osmosis + Claryum

A water SOFTENER  is best for = hardness levels OVER 25-50 GPG

This is very hard water. Meaning lots of limescale problems and white stains around your pipes and plumbing.

A water CONDITIONER is best for = hardness levels UP TO 25-50 GPG

This is low to medium hard water. Good if you just want something to protect your pipes and plumbing from future hard water.mrwatergeek winner badge

  1. I have well water & was tested at 86 gpg. My home is new and appliances arent here yet so was wanting to get some soft water system ideas. I am looking at kenetico, US Water Systems, and Water Right. All are expensive and all companies say I need a big system to handle such hard water.
    Can you recommend a good reliable system?? Its hard to find any good reviews.

    • Hi Art
      Yes, 86 GPG is on the high side so the companies are right, you should be looking for high capacity machines but they tend to over-charge for this and I don’t have the best opinion of Kinetico (read my review here).

      My recommendation is to get a water softener with exceptionally good reviews, customer experiences and then get the highest capacity model that they offer.

      I usually like to recommend that people buy through Amazon because of their reliable customer service in case anything goes wrong and you can also get a qualified plumber to install it for you (direct through Amazon).

      Check out models like the most popular and best selling water softener Fleck with the 80,000 Grains TwinTank Model.
      The Fleck WS 96,000 Grain Model.

      Hope this helps,

  2. I like how you differentiated water softeners and water conditioners. My wife and I have just bought our own separate tumblers and we are considering to buy a water filter as well. We are both leaning towards water softeners. If ever, I would like an expert on drinking water systems to handle the installation process in case we want to buy our own unit.

  3. Is there one system or can you use both a water conditioner and a water softener together to have soft water and not have the scale build up in your pipes?

    • Hi Shirley,
      Getting a water softener does both. It will provide you with soft water AND soft water means NO scale build up in your pipes.
      However, a water conditioner is for people that don’t want a softener. This device doesn’t use salt/sodium so can not guarantee soft water but will gently condition your water to prevent/reduce scale build up.
      Let me know if you need more help,
