Best Water Softener

If you simply want the best water softener out there, we did the job for you and researched different products, finding the Culligan WH-HD200-C Whole to be our top pick. This one is a filtration system that has a bypass shutoff valve to make it easy to operate while it already comes with a 1-inch inlet. It is ideal for whole house operation and has been certified by world standards, such as ANSI and CSA.

For those with an extra budget for a water softener, the Watts Premier 531105 may be a good choice for you. It is a pack of filter solutions that are intended to be used for reverse osmosis. This set contains carbon pre-filters, sediment, post-filters and many others.

The ResCare RK41N All-Purpose may be what you want if you’re on a tight budget. This softening product is a cleaner that contains 1 gallon in one bottle. It can also be used for an existing water softener as a cleaning product so that the quality of the liquid produced will not be altered by content and mineral buildup.

A Little Background

water softener

A water softener can be helpful for places with hard water.


Water softening is the process that involves taking out trace elements in any hard water source, hence “softening”. It is often done by a water softener, which is a kind of filtration system or tool that does the job. There are also special water softeners that come in bottled form.

There are two kinds of sub-methods for softening water: ion-exchange resin and reverse osmosis. Both of them have their differences and similarities.

The ion-exchange resin method exchanges sodium ions with the hard ions of calcium and manganese in hard water, thus making it softer and with fewer metal elements. In short, the sodium content is exchanged with the trace elements and minerals.

It can be kind of a not-so-healthy thing for the body to intake too much sodium (see below) and this is why this method is not always used for a filtration or softening process throughout the world today.


Reverse osmosis is a common filtration process.


The reverse osmosis is another common way of softening. It makes the use of hydrostatic pressure in which hard ions of manganese and calcium are filtered away using a special membrane. Reverse osmosis is the most common way of water softening or filtering.

If you check out your local filtration shop or company, they will most likely be using reverse osmosis as a filtration method.


Distillers can be quite a fortune to set up.


Distillation is another common method but can be downright expensive. If you want your water to be thoroughly pure, distilling it is the best way possible, especially for newborn babies and people with sensitive stomachs to trace minerals, even in nonvolatile salt forms.

Distillation is only suitable for those with delicate medical conditions to ensure that the trace elements do not get in the way of their medication and healthy recovery methods.

Water softeners may also have downsides when used repeatedly. This is because of the sodium content, which may interfere with a person’s health and diet, and may also lead to urinary tract infections and disorders.


Sodium is a common part of the ion exchange process.


Sodium-free diets have been rampant nowadays as kidney and urinary tract problems can be a threat to a person who has consumed too much sodium in their body. There exists some salt-free softeners that have a resin tank with preventive measures for scale build-up.

Purifying liquids can be beneficial for people with sensitive digestive systems, but it may not be that needed if you have a strong immune system. Many studies have concluded that mineral water is still very beneficial for people because our body does still need trace elements at some point.

How we Picked

In choosing the best water softener, you should look for the following criteria for your pick:

Type: it can either come in a liquid form in a bottle or as a system or machine tool for a bigger scale of operation. The liquid form is cheaper, of course, but the machine is what you will really need in order to make the liquid work properly to filter out your desired liquid from trace chemicals.

The machine one should be easy to set up (more on that later) and the liquid solution should come with user instructions on how to use.

Amount per bottle: you have to know how much formula is contained in each bottle, usually expressed in ounces. The amount is important depending on how much you need to use in one go. Since most will be used for a filtration shop or business, it is usually in larger quantities so the more ounces is in the bottle, the less you have to buy in the long run for your filtration business.

Eco-friendly: you have to make sure that the formula is safe for Mother Earth at least. The chemicals should not be too harsh when you throw it away. The smell should not be too strong as well. You also have to consider the list of ingredients that are included in the liquid solution.

Ease of use or installation: the machine should be easy to use and to install with the right amount of directions as to how to operate it. The liquid solution should also have indicated amounts as to how much to mix in one given session. Since it will be a delicate process, the user instructions should be easy to understand, especially for those who do not have experience with any filtration process whatsoever.

Certifications from governing bodies: you should also choose one that has sufficient certifications from governing bodies that dictate world standards when it comes down to any filtration process. This ensures that the product or the machine will be operating as smoothly as possible and the liquid mixture will work as intended to soften the water in the safest way possible without the risk of leaks.

The scope of operation: some are intended for home use while some are for business use. Home use machines can be rare because it can be quite costly. At the very least, most people will use it to establish their own filtration shop or station to make sure that their drinking source is clean and safe for all or to sell filtered water.

Accessories included in the machine system: this can be important to make the setup a breeze overall. The instructions should also teach the user how to use the included accessories.

Compatible machines (for formulas): the softening formula should be compatible with a specific filtration machine. It is usually written in the instructions and labels of the product. There are some liquid solutions out there that can only be compatible or recommended to be used on a specific brand of filtration machine, so be careful when choosing one.

Our Pick

As our top pick for the best water softener, we chose the Culligan WH-HD200-C Whole, which can be ideal for a whole house filtration system. It is great for homes that need a lot of clean filtering as well as those who want to be able to use it for a filtration system for a business.

The included 1″ reinforced inlet and outlet connector made of stainless steel stands to be durable for long-term use and it also makes the installation a lot easier as compared to other brands.

Other Frequently Asked Questions

Q: What are the different benefits of a water softener?

A: A water softener is a great investment to have at home (and for a business) with the following benefits:

Balances your sodium intake There is a kind of process that allows you to put just the right amount of sodium in your source. Too much sodium can lead to urinary and kidney infections, while too little sodium can also be bad for your body. A good balance of sodium is enough to help you achieve a healthier and balanced lifestyle.
Balanced mineral consumption There are minerals that are present in your drinking source that is not really beneficial to the body. However, there are also minerals that are okay for the body. With the help of a softener, you can maintain a good balance between the two.
Helps your pipe and faucet last longer With a softener, you can help clear up the buildup of anything that gets stuck in your faucets and pipes. This can ensure that your plumbing system can last longer with less likelihood of having to call the local plumber for a leak or clogging issues.
Does not damage kitchen utensils There are certain minerals that come out of hard sources that may damage a kitchen utensil and cause corrosion. If you ever own a carbon steel knife then it might get rust easily if your source is not clean.
A healthier skin Many people and experts agree that having a properly filtered source using a softener can be friendly towards your skin. There are some people who may be allergic to certain metals and minerals, even in little amounts, and that’s why they can get rashes and such. With a softener, it might be alleviated.
Conserves appliances In addition to helping kitchen utensils sustain less damage from harsh metals, it also does the same thing for appliances in the kitchen, such as cookers and refrigerators.
Great for a heater system If you have a heater system then you should definitely consider a softer because the mineral deposits can damage it as well when not cleaned properly.
Great for cleaning appliances Cleaning appliances like washing machines will get clogging if you do not have a softener. A softener can help the source become free from sedimentation and other debris to make sure that clogging will less likely happen when washing clothes and the like.

Q: Can it be possible to safely drink softened water sources?

drinking water

It really pays to have a clean and safe drinking source.

A: Yes, softened sources can be safe for drinking. This is because they are still safe and have been filtered out to remove most of the harsh chemicals and minerals like iron oxide and others. The only downside for some people when it comes down to softeners is that they leave a slightly salty taste, which can be bad for people who are maintaining a strict sodium diet.

Q: Which minerals are found in common tap water?

A: If you wash your hands under a faucet in the sink, these minerals are most likely to be found:

calcium milk

Calcium is a mineral commonly found in milk.

  1. Calcium – needed for strong bones and teeth
  2. Potassium – ideal for better blood pressure
  3. Phosphorus – helps in energy conversion from sugar
  4. Magnesium – helps in bones and teeth as well
  5. Sodium – helps maintain blood pressure and fluid balance

Q: How much of these minerals are required for the body daily?

A: On a daily basis, the above-mentioned minerals are needed by an average human being in the following amounts:

Calcium 800 to 1,000 mg
Sodium 1,100 to 3,300mg
Magnesium 300 to 400 mg
Potassium 3,500 mg
Phosphorus 700 mg

Q: How does adding salt help a water softener?

A: This is called the ion-exchange method in which salt is exchanged with the hard minerals like calcium and magnesium. In this way, the salt or sodium is retained in the water while the hard minerals are cast out, resulting in the softening process.

Q: How much salt should be added to the softening device?

A: The softening device should receive about 6 to 8 lbs of salt per 1 cubic feet of resin. Again, this may depend on the size of your tank, such as a brine tank, and you should also consult the user instructions as to how much salt is recommended for the said system.

Q: What are the signs to tell if you live in a place with hard water?

A: Hard water has the following characteristics, and can be treated with a softener:

  1. Your laundry items become stiff in texture
  2. Rust rings can form under your sink and tubs
  3. Your water bill may spike in an unusual way
  4. Whenever you bathe, your skin becomes unusually dry

Q: Why should I filter a faucet?

tap water

Filtering a faucet can have many benefits.


A: Adding a filter to your faucet can have the following benefits:

Safe for children and pets Generally, you would teach your children to wash their hands before eating and drinking, but what if the faucet spits out iron oxide smelling source? You need a softener or a filter for that purpose.
Controls the flow or pressure There are some filters and softeners that can also potentially control the pressure or flow so that it will not be a surprising splash or an annoying small drop when you open the faucet.
Ease of installation Most of these softeners and filters that are specifically made for faucets can be easy to install. Most of them are also lightweight and have simple user instructions so almost anyone can attach them to their sink and faucet systems.
For cooking Obviously, if you are in a rush, you would have to grab your liquid straight from the sink, in which the faucet might have some harsh chemicals if not filtered. This can affect the quality and safety of your foods and drinks. Therefore, you should filter or soften it to avoid such problems.

Q: What is GPG?

A: GPG stands for grains per gallon and is the way to measure the hardness of a water source so that you will know when to get a softener at hand. 1 gpg is the ideal rule of thumb, while anything that is hard is about 7 gpg or more.

Q: How do you know when a filter or softener can be a great choice for your needs?

A: To know if the softener or filter that you chose would be ideal for your home setup or business use, here are some things you need to know about it:

Ease of cleaning We all know that softeners are cleaners as well, but we also have to make sure that the system in itself is also easy to clean in general, otherwise, it will still just get clogged too much when you use it more often.
Good price You have to also consider your budget for the product – will you be using it for home or for commercial use? You have to know how much you are willing to spend or invest in the product if you really need it for your home.
Great performance The level of performance can depend on how much stages of filtration and how effective the softener’s process tends to be in the whole system. Softeners often need the help of a softener product such as in resin or in liquid form.
Durable parts The softener or the filter should be durable in most of its parts to avoid leakage in the system. This is crucial for those with extreme temperatures in which plumbing items can easily crack under the UV rays of the sun.
Simple assembly Not everyone is greatly knowledgeable in terms of plumbing and filtration processes. Therefore, you have to make sure that the softener or filtration system has some decent user instructions in terms of assembly.

Q: Do you also need a softener for an aquarium?

fish tank

Fish tanks, bowls and aquariums can benefit from softening, too.

A: Yes! One of our picks above is intended to be used for a hermit crab tank, and that means that there’s no reason not to use a softener for an aquarium or a fish tank as well! Softeners for an aquarium does the job of removing chlorine and balancing the salt levels in the aquarium itself, making it more natural in term of habitability for the pets that you have, whether it’s a hermit crab, an angelfish or even a janitor fish.

Q: What are the different kinds of purifier filters and their purposes?

A: Aside from a softener, there are filters that vary in terms of design, function, and material, such as the following:

Charcoal filter These are the most commonly used ones today because they can eliminate most impurities from your source. They are used not only on liquids but also on dust in the air around your home.
Activated carbon filter This is a bit similar to the charcoal filter but on a different price. Like the charcoal filter, it traps the dust or mineral to make sure that your source is potable.
UV filter UV filter makes the use of UV light or rays to kill the bacteria and harmful chemicals that are present in your source. This is a more advanced way of filtering and can sometimes be more expensive.
Ion exchange Ion exchange occurs when you exchange sodium ions with the minerals that are present in the source. This is a common method of softeners on how they operate.

Q: What are some ways to prevent hard water stains from forming in your household?

rust stain

Rust stains can form due to minerals.

A: Here are a couple of ways to remove those dirty and unpleasant stains:

  1. Try a store-bought mineral cleanser, vinegar or lemon juice.
  2. Always keep your surfaces dry to avoid staining.
  3. Invest in a water softener to avoid such problems.
  4. Clean up the troubled surfaces once a week.

Q: Why do I need a distiller?

A: Aside from a softener and a filter, a distiller may also be a great investment for your home because of the following purposes:

child drink

Children should only drink something that is safe and clean.

For the kids Babies and children have sensitive stomachs and this is why they may need distilled drinking sources so that they can be free from potential viruses and sickness causing germs.
For cooking It is a lot safer to cook and prepare meals with the distilled source. Because the process of using a softener can sometimes be a concern for sodium diet people, cooking with distilled source can be more ideal for them.
Some distillers are portable You don’t always need to buy distilled drinking sources from your local grocery store – there are portable machines today that can help you distill your drinking source at home.

Q: How is an ionizer different from a softener?

A: Both can be confused with each other, as both can be used in liquid sources, but they do have distinct differences, such as the following:

Criteria Ionizer Softener
Purpose It simply makes the source less acidic and more alkaline It makes the source cleaner and removes iron oxides and other metals
Price Usually more expensive Usually cheaper
Size of unit Usually bulkier Usually smaller

Q: Can I use a water softener for a swimming pool?

A: No, you would have to use a pool cleaner for that task. Water from the swimming pool is a lot more than your regular shower water, and this is why cleaning the pool would mean getting a separate pool cleaner to do the task.

Q: Can you attach a water filter to a shower head?

A: Yes, there are many brands of shower heads out there that allow you to attach a water filter for added convenience. This helps you to filter out the water that comes out of your shower, especially if you are stuck in a place where there is hard water all over the place.

Q: What are the possible problems of the water softener making noise?

A: If your water softener makes a lot of noise, the following problems might be the cause:
