When it comes to improving the quality of your water supply, choosing between a water conditioner and a water softener is a crucial decision. Both systems are designed to address common water issues, but they work in different ways to achieve their goals.
Water softeners use a process of ion exchange to remove minerals like calcium and magnesium, which cause hardness in water.
On the other hand, water conditioners alter the structure of minerals in water to prevent them from forming scale buildup. Understanding the differences and knowing when each solution is best suited for your needs can help you make an informed decision to ensure that your water is safe, clean, and free from contaminants.
Difference between Water softeners and Water Conditioners
Water softeners and water conditioners have distinct differences in their design, but they share a common objective: enhancing water quality. By employing different filtration methods, they effectively reduce limescale and other impurities present in the water. Ultimately, their goal is to provide you with cleaner and purer water.
Water softeners
A water softener is like a magic device that waves goodbye to pesky minerals like calcium and magnesium ions. It does this through a process called ion exchange with the help of salt. The tougher minerals are swapped out for sodium ions, and then water flows through these awesome resin beads. These beads capture all the minerals, whether they’re good or bad. But here’s the catch: over time, those minerals start to pile up, and the resin bed needs a good flush and some fresh salt.
Keeping a water softener up and running does require some maintenance and a bit of money, especially if you live in an area with super hard water. And, let’s not forget about that some sodium (salt) gets added to your water. While it works wonders for your water, it might not exactly the healthiest thing to consume. For this reason it’s normally advisable to have your kitchen cold tap on an unsoftened supply.

How Does a Water Softener Work?
A water softener works by removing the minerals that make water hard, such as calcium and magnesium ions. It uses a process called ion exchange to achieve this. The water softener contains a tank filled with resin beads that are coated with sodium ions.
As hard water passes through the tank, the calcium and magnesium ions in the water are attracted to the resin beads and swap places with the sodium ions. This process effectively removes the hardness-causing minerals from the water.
Over time, the resin beads become saturated with calcium and magnesium ions, and they need to be regenerated. This is done by flushing the tank with a brine solution, which contains a high concentration of sodium ions. The brine solution displaces the calcium and magnesium ions from the resin beads and recharges them with sodium ions. The excess minerals and brine solution are then flushed out of the system, and the water softener is ready to continue softening the water.
Water Conditioners
A water conditioner is similar to a salt-free water softener but has some unique advantages. Instead of removing all minerals, it changes the way minerals interact with your plumbing and appliances, while still keeping the good minerals that are beneficial for your health. Plus, it requires no ongoing maintenance or added expense of salt. Simply add it to your system and forget about it!
By using a water conditioner, you’ll be saving time on cleaning and money on appliance maintenance because it helps reduce limescale build-up in your home. On top of that, you’ll still enjoy the health benefits from the good minerals in the water. That’s why many people prefer salt-free water conditioners over traditional water softeners.
Water conditioners work in different ways, such as through ion polarization, magnetism, or electromagnetism using a magnetic field. Some methods require an electric connection, while others don’t. The cost of each method will vary based on these factors.

How Does a Water Conditioner Work?
A water conditioner is a device used to improve the quality of water by removing or reducing impurities, such as chemicals, minerals, and contaminants. Unlike a water softener, which specifically focuses on removing hardness minerals (calcium and magnesium), a water conditioner can address a broader range of water problems.
The working principle of a water conditioner varies depending on the specific type and design of the device. However, common methods used in water conditioners include:
1. Filtration: Water conditioners often incorporate various types of filters to remove sediments, particulate matter, and larger impurities from the water. These filters may use activated carbon, ceramic, or other materials to trap and remove contaminants.
2. Chemical treatment: Some water conditioners use chemicals, such as chlorine or ozone, to kill bacteria, viruses, and other microorganisms present in the water. These chemicals disinfect the water, making it safe for consumption.
3. Ion exchange: Ion exchange is a process that involves the removal of unwanted ions from water and replacing them with more desirable ions. In a water conditioner, ion exchange resins or media are used to attract and remove unwanted ions, such as heavy metals or certain minerals, from the water.
4. pH adjustment: Water conditioners may also have components or systems to adjust the pH level of the water. This can be done through the addition of chemicals or by passing the water through a bed of media that neutralizes acidity or alkalinity.
5. UV sterilisation: Ultraviolet (UV) light is used in some water conditioners to kill bacteria, viruses, and other microorganisms. The water passes through a chamber where it is exposed to UV light, which damages the DNA of the microorganisms, rendering them unable to reproduce and causing their death.
Overall, the specific working mechanism of a water conditioner depends on the intended purpose and the specific technologies incorporated into the device. The goal is to improve the quality of water by removing or reducing impurities, making it safer and more suitable for various purposes, such as drinking, cooking, and bathing.
When would a water conditioner be the best option?
If soft water is your main goal, water conditioners cannot compete with water softeners as they do not actually soften the water. However, there are certain situations where water conditioners can be a better choice than water softeners.
- In environmentally friendly applications
Water conditioners are more environmentally friendly than water softeners because they do not release chlorides into wastewater. Water softeners inject chlorides into wastewater, which are challenging for treatment plants to remove. Water conditioners also use less water and prevent harmful salts from entering city water. - When scaling is the only concern
If you are only worried about scaling in your home and don’t mind the presence of calcium and magnesium in your water, a water conditioner may be the right choice. Water conditioners cause the minerals in hard water to crystallise, preventing them from coating pipes or appliances. - If you are on a low-sodium diet
Water softeners add sodium to the water as they exchange sodium ions for hardening ions. This can be a problem if you are on a low-sodium diet, as the sodium content in softened water can have adverse effects. In this case, using a water conditioner instead of a water softener will ensure that only naturally occurring sodium is present in your water.
If you want to minimise the sodium content in your water, you can consider implementing a reverse osmosis system after your water softener or conditioner. This system can reduce levels of sodium, iron, lead, and other contaminants in water. - If you do not need a point-of-entry system
Water softeners are point-of-entry systems that treat all water entering your home. On the other hand, water conditioners can be either point-of-entry or point-of-use systems. If you only notice scaling in your water heater but not elsewhere in your home, a point-of-use water conditioner may be the right choice. This type of conditioner can be installed specifically for faucets or individual appliances, such as pre-treatment for a hot water heater that is more susceptible to limescale buildup.

When would a water softener be the best option?
Water softeners are the most effective systems for softening water because they use salt to remove minerals that cause hardness. As a result, they are the preferred choice for situations that require soft water.
When you need truly soft water
Water softeners and water conditioners serve different purposes. While water conditioners prevent limescale buildup by crystallising calcium and magnesium, they do not remove these minerals. This means that their effects are limited to plumbing preservation. On the other hand, water softeners produce water that is free from hardening minerals, providing a range of benefits. Soft water helps prevent limescale buildup, itchy skin, flat hair, spots on dishes, faded color in clothing, and soap scum buildup. To enjoy the full benefits of soft water, using a water softener is the way to go.
