Knowing what type of water treatment system will work best for our home can be extremely difficult. With the multitude of treatment systems out there, you can only sometimes be sure which one your water and home need. Water conditioners and water softeners are just some of those water treatment systems. 

Water conditioners treat hard water and reduce scale buildup, while water softeners remove hardness-causing minerals from the water. There are similarities and differences between these systems. When deciding on what to install in your home, you want to pay attention to your type of water, water usage, house size, and the number of people living in the home. Whatever your decision, Logan Services is ready to help you get the perfect and correct water treatment system for your home and water. 

Below are the specifications of water conditioners and water softeners to help you know which one might work best for your water treatment needs.

What is a Water Conditioner?

A water conditioner is a device to treat hard water and reduce scale buildup without using traditional ion exchange methods involving salt. Water conditioners use physical or chemical processes to alter the behavior of hardness-causing minerals (mainly calcium and magnesium), so they don’t form scales. There are many different types of water conditioners, including:

Template-Assisted Crystallization

  • It uses a catalytic media to convert dissolved hardness minerals into microscopic crystals. This process is effective in preventing scale buildup on pipes and appliances without using salt or chemicals. It requires little maintenance and doesn’t produce wastewater.

    Electromagnetic and Magnetic Conditioners
  • This process uses magnetic and electromagnetic fields to alter the structure of hardness minerals, preventing them from adhering to surfaces and forming scale. It’s easy to install and maintain, no chemicals or salt are required, and it works well in small spaces.

  • It uses chelating agents (such as citric acid) to bind hardness minerals, preventing them from forming scale. The minerals dissolve in the water, improving the effectiveness of soaps and detergents. It is often used in combination with other water treatment systems.

    Carbon Filtration
  • Activated carbon filters can remove chlorine and organic compounds and improve taste and odor. Although they aren’t traditional water conditioners, they are sometimes marketed as such when combined with other conditioning methods. With conditioning effects, you’ll see improved water quality and reduced contaminants.

You can reap many benefits when getting a water conditioner for your home. These benefits include:

  • Scale Prevention – Scale buildup is prevented in pipes, water heaters, and appliances, extending their lifespan and maintaining efficiency.
  • Low Maintenance – No need to add salt or chemicals; it requires less maintenance than a water softener.
  • Environmental Impact – It does not discharge salt or brine into the environment, making it more eco-friendly.
  • Health Considerations – Do not add salt to the water, which can benefit people on low-sodium diets.

As with most things, water conditioners have limitations as well. Consider these limitations when deciding on a water condition for your home:

  • Effectiveness – The effectiveness of water conditioners can vary based on water chemistry, flow rates, and the specific technology used.
  • Does Not Soften Water – Unlike water softeners, water conditioners do not remove hardness minerals. They change how the minerals behave but do not reduce the overall hardness. 
  • Limited Contaminant Removal – Water conditioners are not designed to remove other contaminants such as iron, manganese, chlorine, or sediment. Additional filtration systems may be needed for comprehensive water treatment. 

What is a Water Softener?

A water softener is a water treatment device that removes hardness-causing minerals from water. It is designed to remove dissolved minerals such as calcium and magnesium. 

  • Calcium significantly contributes to water hardness and can cause buildup on pipes and household appliances. 
  • Magnesium contributes to water hardness and can also aid in scale buildup.

A water softener provides many benefits for treating water in the home. When calcium and magnesium are removed from the water, it prevents scale buildup on pipes and fixtures, improves the cleaning process, extends appliance lifespan, and improves the softness of skin and hair. These benefits make a difference in the everyday things you use in your home. 

Again, as with most home improvement projects, water softeners also have limitations. These limitations include:

  • It doesn’t remove all contaminants – A water softener will not remove high concentrations of iron and manganese, sulfur, sediment, bacteria, viruses, or chemicals like pesticides.
  • Maintenance and salt use – Regular maintenance is required, and the brine tank must be filled with salt about monthly. 
  • Space requirements – Ensure your home has enough space for the resin and brine tank. 
  • Not effective for all water issues – Water softeners are specifically designed to remove hardness in water. Water with high levels of iron, sulfur, or other specific contaminants will not be treated effectively with a water softener.

Key Differences Between Water Conditioners and Water Softeners

Water conditioners and water softeners both benefit your water, but there are many differences between them. These differences can make them fit into your water treatment needs. Here are the key differences between water conditioners and water softeners:


  • Water Conditioners – Alter the behavior of hardness-causing minerals to prevent scale formation without removing the minerals from the water.
  • Water Softeners – Remove hardness-causing minerals (calcium and magnesium) from water.

  • Water Conditioners – Effectiveness can vary based on water chemistry and the specific technology.
  • Water Softeners – Highly effective at removing hardness minerals and preventing scale buildup.

  • Water Conditioners – Generally require less maintenance than water softeners. 
  • Water Softener – Requires adding salt regularly.

    Installation and Space Requirements
  • Water Conditioners – More compact and easier to install.
  • Water Softeners – Require space for the resin tank and the brine tank.

  • Water Conditioners – Often lower initial cost compared to water softeners.
  • Water Softeners – Higher initial cost due to the complexity of the system. 

Comparison of Water Conditioners vs Water Softeners

While water conditioners and water softeners have distinct differences in their functions and methods, they do have some similarities in the goals and benefits they provide for your water. 

  • Purpose – Both water conditioners and water softeners are designed to address issues with hard water. They aim to prevent the negative effects of hard water on plumbing, appliances, and overall water quality.
  • Scale Prevention – They work with calcium and magnesium ions to prevent scale buildup.
  • Protecting Plumbing and Appliances – Both systems help protect plumbing, water heaters, dishwashers, washing machines, and other water-using appliances from the damaging effects of scale buildup. This can extend the lifespan and improve efficiency. 
  • Improving Cleaning Efficiency – They both improve how soaps and detergents work with or remove the minerals from the water. 
  • Enhancing Water Quality – They both enhance water quality by addressing hardness-related issues. This can lead to better-tasting water and improved water quality for household uses.
  • Maintenance of Personal Care – These systems help prevent the drying effects of hard water by reducing or altering hardness minerals. They can also improve the look and feel of skin and hair.
  • Environmental Impact – Both systems are designed to be environmentally friendly in specific contexts but approach it differently. 
  • Custom Solutions – These systems come in various sizes and capacities, allowing for customization based on household size, water usage, and specific water quality needs. 

When choosing between the two systems, the decision depends on specific water hardness levels, environmental concerns, maintenance preferences, and individual health considerations.

When to Use a Water Conditioner vs a Water Softener?

While both a water conditioner and a water softener will work to help with hard water issues, there are times when one makes more sense than the other. Here are some guidelines to help you decide when to use each:

Water Conditioners:

  • Moderate Hard Water – A water conditioner could be sufficient if you have moderately hard water or are primarily concerned with preventing scale buildup. It can effectively prevent scale without removing minerals.
  • Environmental Concerns – Water conditioners are more friendly to the environment. They do not use salt or product brine wastewater. 
  • Low Maintenance Preferences – Water conditioners usually require less maintenance than water softeners. If you need something with minimal upkeep, you want a water conditioner.
  • Health Considerations – If you are worried about the sodium water softener salt adds, a water conditioner is a healthier alternative, as it adds no salt.
  • Space Constraints – Water conditioners tend to be more compact and easier to install, making them a good choice if you have limited space for a water treatment system.
  • Cost Considerations – Water conditioners have lower upfront and ongoing costs since they don’t require the regular purchase of salt and typically do not use as much water.

Water Softeners: 

  • High Hardness Level – A water softener is a better option for removing calcium and magnesium ions if your water has high hardness levels. 
  • Significant Scale Buildup Issues – A water softener provides a more comprehensive solution for severe scale buildup in pipes, appliances, and fixtures by completely removing hardness minerals.
  • Sensitive Skin and Hair – A water softener can help provide gentler water for sensitive skin and hair. Your skin will not feel as dry, and your hair will not look as dull. 
  • Improving Cleaning Efficiency – Soaps and detergents will work much better with a water softener, leading to better cleaning results and less soap scum. 
  • Protecting Appliances and Plumbing – We all want our appliances to last as long as possible. A water softener can provide better protection against scale buildup and increase the lifespan of your appliances.
  • Customizable Options – Water softeners come in different sizes and capacities, allowing for custom options dependent on house size, water usage, and number of people living in the home. 

These guidelines help you decide which system works best for your home and when each makes sense.


How do I choose between a water conditioner and a water softener?

When choosing between a water softener and a water conditioner, consider factors like the hardness level of your water, your budget, maintenance preferences, and any health concerns related to sodium intake. Getting a water quality test can help you determine the best option for your home.

Are water conditioners effective at reducing hard water problems?

Water conditioners can be effective at reducing scale build-up and mitigating some hard water issues, but they won’t address all of the problems caused by hard water, such as soap scum and mineral deposits. In that case, a water softener may be a better solution.

Can a water conditioner replace a water softener?

It depends on your home’s water quality needs. Water conditioners can reduce scaling but may not be as effective as a water softener in removing all the hardness causing minerals from your home’s water.

What are the benefits of using a water conditioner vs a water softener?

Water conditioners are easier to maintain, don’t require salt, and are more environmentally friendly. Water softeners provide complete removal of hardness-causing minerals, leading to softer water that is better for your appliances, dishes, hair, and and skin.

Do water conditioners remove minerals like water softeners?

No, water conditioners don’t remove minerals. They change the way minerals behave to reduce scaling, whereas water softeners actually remove hard-water causing minerals from your home’s water.
