The regular water supply that we receive in our homes and use everyday is mostly hard water. This means that there are still hard mineral deposits in the water that flows through your plumbing. Soft water has a lot of advantages compared to hard water which is why water softeners are being used. However, there are many kinds of water softeners available in the market and they all operate differently. There is always something that fits your needs. In the following text, we will narrow down these kinds of water softeners and briefly explain their advantages and disadvantages to help you make a decision. 

What is a water softener?

Before we get into more details, let us first clarify what a water softener is for. Basically, these are products that convert hard water to soft water. Hard water is filled with mineral deposits like calcium deposits, magnesium carbonate, and manganese. There are a number of indicators that tell you you are using hard water. If your soaps and shampoos do not lather much, your dishes and utensils have dark spots, dark rings on the bathtub, slight stains on your laundry, scale deposits in your kettles – these are just some clear signs that you have hard water circulating in your pipes. You may want to start thinking about getting a water softener. 

These mineral deposits in hard water are not necessarily harmful to the health but there can be long-term damages to your plumbing and your appliances that will cause you hassle in the future. Based on the US Geological Survey, around 85% of American households experience problems related to hard water.

Problems posed by Hard Water

Like we said before, hard water is not a public health threat but it could possibly become a problem in the future. Your plumbing system and the appliances that use water are the ones most at risk. And you will only experience these problems in the future after too much exposure to hard water. Mineral deposits in hard water tend to crystallize and form in the presence of heat. As the residue builds up, it could be a cause of clogging in your pipings and the internal circuitry of your appliances like the dishwasher, washing machine, coffee machine, and water heating systems that will lead them to malfunction. The efficiency of water heaters decreases by 22 to 30 percent if there is hard water residue based on a study by the Water Quality Research Council at New Mexico State University. 

These hassles, if left unresolved, will disrupt your daily tasks like cooking, bathing, cleaning, and doing laundry. Soaps, shampoos, and other cleaning agents lose some of their lathering factor when reacting with calcium and magnesium deposits and you will be forced to apply more of the product which is a wasteful practice. As these deposits accumulate on surfaces, they also leave a stain which commonly appears on bathtubs and tiles, dark spots on plates, and residue on other kinds of kitchenware. Other minerals like iron and manganese can also affect the appearance, odor, and taste. 

As for the health aspect, although it is not very common, hard water can cause rashes and other problems especially to people with overly sensitive skin. The foreign substances present in hard water alters the normal pH of the skin and can block the pores. 

Benefits of having soft water

There are a lot of advantages in using soft water, not just for your health but for the overall household expenses as well. In order to produce soft water, you will obviously need a water softener. So here are a number of reasons why it would be a good investment:

  • Everything that soft water touches, it softens. That goes for the skin and hair when you take a bath and your clothes when you do your laundry. Regular use of soft water will improve the condition of the fabric of your clothes.
  • Extend the life of your appliances. If they are kept in good condition, then they will most likely function longer. 
  • In addition to the longer lifespan, appliances also tend to consume less energy when they are functioning well. It’s not exactly a benefit that is immediately noticeable but in the long run, you will realize that it’s worth it. 
  • Lesser consumption of soaps and detergents. Hard water renders these products less efficient by decreasing the lather factor. Meanwhile, soft water does the opposite so the benefit there is that it would take a long time before you run out of these products. You do not need to purchase them frequently. 
  • Keeps surfaces clean and residue-free. Soft water does not create stains on plain surfaces and does not leave scale residues on kitchenware.

The different types of water softeners

1. Salt-based (Ion Exchange) Water Softeners

This is the conventional type of water softener that is commonly used in many households. Salt-based softeners can circulate soft water throughout the entire house with high flow rates. It basically works by entrapping the calcium and magnesium ions in a resin and releasing sodium ions. Hence the term ‘ion exchange.’ The resin can be refueled with salt to provide more sodium ions when the supply is running low. This usually needs to be done once every week.

The sole function of this method is to get rid of the hard water deposits but not a complete filtration that includes chemicals and bacteria. The ion resin typically lasts for a couple of years and replacement does not cost much, making this system one of the most budget-friendly there is. 


  • Complete removal of hard water mineral deposits
  • Long-lasting


  • Needs to be maintained weekly
  • Consumes a lot of salt

2. Salt-free Water Softeners

This system takes the weekly refill task off your shoulders since it does not use salt to operate. The minerals do not get removed from the water but they are chemically altered in such a way that they do not solidify and can no longer stick to surfaces where the water flows. 

Salt-free systems initially cost more but you do not need to worry about any more future purchases since they do not use salt nor need regular refills. They are also more compact and do not have other special equipment for draining. It also has a filtration feature consisting of multiple stages that can remove other foreign substances and bacteria present in the water. 


  • Does not require maintenance
  • Does not need sodium salts
  • Can also get rid of other water content


  • Costly at first
  • Mineral deposits are not 100% removed

3. Portable water softeners

Soft water on the go. That is the ultimate feature of this system. This works great for people on the go such as those who live in travel trailers or mobile homes. It does not run on electricity and there is quite a long interval in between salt refills. It also does not cost much to regenerate because regular table salt will suffice and there are no other special tools needed to do so. The water flow may not be as abundant as that of a regular-sized system but it is enough to supply a single bathroom and provide clean drinking water for a group of people, making it slightly cheaper than the water softeners used for an actual household. 


  • Portable and compact
  • Perfect for travel and mobile living


  • Water flow is limited
  • Salt-based

4. Showerhead Water Softeners

Some people cannot afford to invest in the regular softeners that are meant for the whole household. Also, they may not have that much of a need for it. Showerhead softeners is a cheaper option if you only want to have soft water supply in your bathroom for bathing and to avoid the hard water stains on your bathtub and tiles. Using soft water for showering or bathing has a good effect on your hair and skin by making them softer and smoother. You won’t consume a lot of soap because soft water does not affect the lather. 

Installation is fairly easy. You just have to replace the old showerhead and attach the softener. It works by filtering out the mineral deposits. The cartridge filter has to be replaced every two months. There are also showerhead softeners with vitamin filters that provide vitamins to your water. However, they might come with other additives like scents that may not work well for you. 


  • Affordable
  • Easy to install


  • Soft water supply is limited only to the shower
  • May contain other undesirable additives 

5. Reverse Osmosis Water Softeners

This kind of system is not mainly for water softening but the way it operates removes foreign matter and other chemicals in the water. Reverse osmosis subjects water to a complex filtration process through an osmotic membrane and can also incorporate other healthy minerals so it is still safe for drinking. They are usually installed under sinks and have their own faucet as well so you can have soft water directly from the tap. There are more filters through which the water also goes that guarantees maximum removal of impurities. 


  • Readily available drinking water if added with minerals
  • Unlimited soft water directly from tap


  • Limited only to one faucet
  • Quite costly

6. Magnetic Water Softeners

This type of water softener operates differently compared to the regular systems. It works similarly to salt-free softeners by preventing them from solidifying. It is not widely used yet since it is still new on the market. Magnetic softeners are also more affordable and easier to install compared to the regular ones but still offer the same benefits. Installation is hassle-free. You only need to attach the magnets around the existing pipes. The magnetic field will modify the water that flows through the pipes. However, you will need to plug this system into an outlet in order for it to function.


  • Affordable
  • Hassle-free installation
  • Pipe cutting not needed


  • Neutralization only of hard water deposits, not removal
  • Requires electrical power

7. Template-assisted Crystallization

Now we are on to one of the controversial water softening systems available today. Template-assisted crystallization is the method that works best with FilterSmart systems. It operates a lot like electromagnetic systems but also shows promise in reducing scale residue buildup according to a third-party research study. 

On a more detailed note, the crystallization occurs in a molecular sense in which the calcium and magnesium elements react with catalytic beads and are chemically altered so they lose their tendency to precipitate and react to soaps. Basically what happens is that instead of on the surfaces, the residue sticks to the resin. So the resulting water flow is free from the larger particles that form lime scale residue.

8. Dual-tank Softeners

This kind of system works either via ion exchange or TAC method. It operates 24/7 and is designed to supply big households, industrial facilities, or large establishments that need a consistent flow of soft water. Single-tank softeners are rendered unusable during regeneration. In this system, there is another available tank ready for use for whenever one undergoes regeneration. That way, the supply is never cut off. 

For TAC, there may be more demand in flow and more foreign matter to be removed from your water. You can also opt to filter chlorine and put in additives to make the water taste better. Dual tanks are also referred to as “combination” systems or twin tank systems and they are quite in demand on the market. Have a look at our dual tank softeners available. 

What to consider in dual tank softeners 

Space is the number one factor that you need to keep in mind when on the market for a dual tank. It needs to be situated in a spot near the main inbound water pipeline to supply the whole house or building. There needs to be a drain for backwashing and if the unit needs an electric source, there should be an outlet near it. Learn more about proper placement of water softeners here.

Other information you should take note: a certification issued by the NSF (National Sanitation Foundation) and a warranty on crucial parts like the mineral tank for 10 years and control valve which is 3 years. Water softeners generally last an average of 20 years. 

Regenerating Water Softeners in 3 Different Ways

You can regenerate water softeners using a meter, a timer, or by manual means. 

1. Meter Regeneration

This is the most common and widely used kind of regeneration method. It works by regulating the amount of water consumption. When the meter is set, it will then estimate based on how much water is consumed and the hardness of the water supply. 

2. Timer Regeneration

It has a specific time interval in between regeneration processes. You basically schedule the frequency of regeneration. This kind is more affordable than meter systems but tends to consume more salts.

3. Manual Regeneration

You call the shots here. You choose when you want to regenerate your water softener which means you also have to be the one to monitor. This method is the cheapest and most efficient and is advisable for small-scale water softening systems. 

A Guide to Picking your Water Softener

In this part, we will give you some surefire tips and advice from experts before you make that purchase. We will also compare the types of softeners that have already been listed. If you want to know what you need to consider before buying, then you’re in the right place. 

Here are some ideas to help you narrow down your choices and select the best water softener that fits your needs. The following is your research guide slash criteria for your next water softener shopping trip. 

  1. First off, you need to decide if you want a single or dual softener. If you ask us, we would definitely recommend getting a dual tank since it’s cheaper and the parts are safely separated. The electronic parts are at a safe distance from the tank that holds the salt solution. As long as you have the right space, a 2-piece softener is a better choice.  
  2. For a small household or building, a single unit can be enough. Do not just think about the space it’s going to take up but consider the workload that it is able to carry out. Single units consume less salt but also supply less water. It might be enough for those who live alone or with a partner or for small families. 
  3. Brandless component parts are the way to go. Do not be deceived with fancy brands. Though they hold a reputation for renowned quality, their parts are made uniquely so that consumers would still go to them for repairs and replacements. It would be best if the unit you buy is made of parts that can be bought in local hardware stores so that you won’t have to be entirely reliant on the brand to provide you with maintenance and repair services after a long time. 
  4. Trust the legends. Pick brands that have already been in the business for a long time. Chances are,  they have already resolved most of the consumer problems that were encountered. Go for manufacturers with good reviews and positive feedback from customers.
  5. Get it from a good source, preferably locally. Local suppliers have an idea on the type of water in your community and could give you an idea on what works well for your home. They can explain better the technicalities of having a water softener and you can voice out your concerns and ask questions before finally making the purchase. 
  6. Find a smaller version of an industrial water softener. This kind of system are built for heavy duty workloads which means they are more sturdy, long-lasting, and usually have high capacity.
  7. Low maintenance remains a wise choice to this day. You want to make sure that your softener, as much as possible, does not require any special tools in order to be maintained or to have one component repaired. 

What features to look for

The following guide will tell you the most important features of water softeners that you have to bear in mind to be able to make an informed decision about what unit suits your needs. 


If you are aiming to buy a salt-based water softener then the first thing you should consider is the resin capacity. You need to have a rough estimate of the amount of water that you consume on a daily basis depending on the number of people in your household. A bigger resin capacity also means that you do not need to regenerate frequently. The lowest capacity starts at 16000 up to 96000 usually for dual tanks. There are softeners that do well with iron-rich water from deep wells. Take a look at the resin content in the brine tank because that also determines the amount of salt that it will consume. 

Available Area

Check the space around your main inbound water line. You cannot go for a large water softening system in a small area. Middle-of-the-pack softeners already usually work fine for a lot of households so dual tanks consisting of iron tank and brine tank might suffice. Make sure that you are informed of the important details such as dimensions and measurements of the unit. You can look up this information online.

Bypass Valve

Under circumstances where you do not need a supply of soft water. The bypass valve somehow passes the water through the system without it passing the softener itself. It is important that the valve is easy to locate and operate. Look up the brand Fleck – they are a brand that specializes in manufacturing components for water softeners. Bypass valves typically have two red arrows and they need to be pulled together to redirect the water and not make it go through the softener. 

Regeneration Setting

We have tackled this before about the mode of regeneration for water softeners. You can have a metered or timed regeneration. For the former, it will monitor the amount of water being consumed and then regenerate when it reaches a specific level that you set. The latter, on the other hand, has a predefined schedule as to when it will regenerate depending on your estimated usage on a timely basis. However, for these regenerations with a preset, you need to have an accurate estimation or else you will have a shortage if the supply runs out ahead of schedule or an excess if there is still a lot left because not much was consumed. 

Best water softener brands

The following are some comments and reviews on some widely used water softener brands. 

SpringWell Futuresoft Salt-free Water Softener

This brand is without a doubt one of the most highly-renowned in the water softening industry. SpringWell Futuresoft makes both salt-based and salt-free systems that are proven to be more efficient and well-functioning compared to other brands because they have their own exclusive media that’s unlike any other.

FutureSoft uses a template-assisted crystallization process for water softening. This method works well for the hair, skin, clothes, and appliances that use water. In terms of maintenance, you only have to change the filter once a year! The unit already comes packaged with all essential parts, including a bypass valve and a lifetime warranty. We strongly recommend availing their Whole House Water Filtration System as well so you have the entire SpringWell care.

A DIY Water Softener Installation Guide

Almost all house filtration systems are installed the same way. However, installing water softeners specifically can require some extra help and if you are not adept or technically knowledgeable about it, it is best to seek the assistance of an expert. Regardless, here are some basic instructions to help you out. 

  • Turn off the main water supply and find the inbound pipe. This is usually found in the garage or basement.
  • Cut the pipes that run between the water meter and before it goes into the house. 
  • Place your pipe connection along with the 3 valves – two valves prevent water from coming in and out of the softener itself and the third valve is the bypass valve. 
  • Ensure proper placement and attachments. You might need a soldering iron.
  • Use a ⅜ plastic tubing to connect the media tank to the brine tank.
  • Use a hose clamp to connect the drain line to the drain elbow. 
  • Finally, attach the discharge pipe to the wastewater drain.


All in all, there are six kinds of water softeners that we included in this post. You can choose from the variety of ways that they operate and whether they can accommodate the entire house or only one showerhead or faucet. To recap:

  • Ion-exchange softeners replace the calcium and magnesium with sodium ions.
  • Salt-free systems chemically alter the minerals’ tendency to precipitate and form scale residue. 
  • Portable softeners can be carried anywhere and attached to a lot of water sources without need for a power source.
  • Showerhead softeners provide soft water only for a single showerhead, giving you soft water for use during baths and there is less formation of stains on tile surfaces.
  • Reverse osmosis subjects the water through an osmotic membrane that supplies it with other minerals to make it drinkable and at the same time removing hard water mineral deposits.
  • Lastly, magnetic water softeners can be attached to the pipe and will electromagnetically modify the flowing water, changing the chemical composition of the ions present.

Water softeners can fulfill your need for soft water, may it be for the purpose of having soft skin and hair or not having to worry about stains on your tile surfaces. It can be a good investment for your household and beneficial to your lifestyle.
