BUYING GUIDE FOR THE Best Water Softener 2021

You need a detailed-buying guide when you want to have a reasonable water softener comparison. When you look for the Best Water Softener 2021, you want the best results with the most efficient costing. It makes sense why you are concerned about which water softener you should go for. It’s excruciating to know your water softener is useless and inefficient yet expensive. And this expense is not just one time. You should also keep its maintenance cost in mind. This is why you are doing an excellent job of digging into the Best Water Softener 2021 for you.

There are many factors involved in making a decision on which softener you should choose. What if your water softener is impressive but does not just fit in your required area. There is no use if it does not give enough flow rate. You should take the time to understand the importance of the water softener that suits you. You should take grain-capacity, hardness level, flow rate, available area, softener size, features, and budget into consideration. We have discussed every aspect in detail below.

Let’s jump in.

 Grain Rating 

We rate regular water softeners by grain-capacity, obviously. Your hard water has many hardness-causing grains like those of calcium, magnesium, and others. So, every water softener has some capacity to process these grains after you need regeneration. But wait, what is regeneration by the way? It is a process by which we remove impurities from water softener so that it may collect more. While deciding for the Best Water Softener 2021 for you, you should decide how much grain capacity or grain rating you need.

So now the question arises; how much grain rating do you need in your water softener? Well, it depends upon the hardness in your water and the number of people who use it. To determine the hardness in your water, you can test your water through a particular kit. You can easily purchase it from the market. Also, lots of water softeners come along with the test kit. Just to give you an idea, city water contains almost 15 grains per gallon on average. We will discuss it in the next section as well.

For example, if you are a family of four and you consume 320 gallons of water per day. It means you need to filter 12800 grains from your hard water. So, here is a pro-tip, getting a water softener with more grain rating means it needs regeneration less often, saving you lots of bucks. Now, as you know about grain rating and regeneration, you should decide the Best Water Softener 2021 for you.

 Water Hardness Level 

We determine the hardness level by the number of hardness-causing grains in your water, obviously. It should be noted that our water might have 10 to 40 grains per gallon. On average, city water has 15 grains per gallon. To decide which water softener is just for you, you should know the hardness level in your water. You can determine the number of hardness-causing grains in your water by estimation or a proper test kit if your water is slightly hard, your dishes dry with mineral spots.

If faucets accumulate calcium or soap scum sticks to shower walls, your water is hard. And if your skin dries, your water creates visible stains and clogs pipes; your water is extremely hard, obviously. Now you should choose a water softener according to the hardness level in your water. Higher the hardness level, the more grain-capacity your water softener should have. Getting water softener with higher grain capacity will result in fewer regeneration cycles. It will save you a lot of bucks in the long run, obviously.

 Flow Rate of the Best Water Softener 2021 

The flow rate is an essential factor to note while choosing the Best Water Softener 2021 for you. It is the quantity of water supply per minute. We usually calculate it in gallons per minute. Just to give you an idea, a shower requires two gallons of water per minute, a washing machine needs 1.5 and a faucet only one. You should also how many family members are going to use water simultaneously.

You regularly want a minimum of 4 gallons of water per minute, if you are single or two. But if you are a family of three, you would like almost 6 GPM. To add to your knowledge, we can determine the flow rate by the amount of resin that a water softener contains. For example, if a water softener has 50 grains per gallon capacity, it can produce 5 gallons per minute for every cubic foot of resin. We hope you are more knowledgeable now to make a decision.

 Available Area 

You should also consider the available area while choosing the Best Water Softener 2021 for you. If the s for a water softener space very small, you would like to get a compact water softener, of course. So, measure the available area for water softener before you purchase the device for you. Also, if your intake pipes are too small, you cannot handle a water softener of a relatively larger size.

If you have a small house, we recommend you to get a two-piece system featuring just brine and an iron tank. On the other hand, dual systems are larger and more expensive, and they will not fit into your available area. Get the water softener that suits your needs. Always check for the particular dimension and measurements for the water softener. Also, measure the available area in your house as well. Lots of people ignore this little thing and repent afterward.

 Water Softener Size 

This is related to the previous section. If you know the available area in your house, you should then see the size of the water softener. The size of the water softener does not only depend upon the available space you have. It also depends upon your water softening requirement. Bigger size means more capacity a water softener has. It will be more pricey too. You also got to live within your means.

But the ability to soften your water is also essential. This is why you are getting it. Aren’t you? To buy the correct size of the water softener, you should know the amount of water you need for your family. You can calculate it by multiplying the number of your family members by 75. Now multiply this number to the number of grains per gallon. And here we go, you just determined the total capacity of the Best Water Softener 2021 you need.

 Bypass Valve 

It is the valve that lets the water bypass the device. While considering a particular water softener, you must know if it comes with a bypass valve. Even if you buy a separate bypass valve, it will not be a bad investment either. You will make use of it for many other activities. A bypass valve is a beneficial thing to have. Especially during the summer, we can use it to make our softener more efficient. It helps you save a lot of water.

When you make use of bypass, you will enjoy the water for all your needs, from watering your lawn to new trees in your house. You can always put those bypass valves back. If your water softener needs repairing, you just need to use your bypass valve rather than going all the way to your main water line. Also, a bypass valve can help you get ready for some issues proactively.


You cannot ignore your budget when buying something. And if it is the Best Water Softener 2021 that you want to buy, it becomes more important to consider your budget. It is because water softener is not just a one-time investment; you need a lot more for its upkeep. So you would want to make sure that you neither spend an extra buck nor be deprived of making real use of your water softener. As a general rule, if you spend more now, you will need to spend less in the future.

A water softener based on salt is comparatively more expensive to the salt-free systems. You could end up spending almost $400 to $3000 to get a salt-free residential water softener. But if you are on a budget, you should go for a descaler. But honestly, if your water is hard enough, we recommend you to get a salt-based water softener system. A salt-based water softener is an expensive option but extends the life of your pipes and appliances. In contrast, a salt-free water softener is a cost-efficient and eco-friendly option to soften your water.

 Features and Controls of the Best Water Softener 2021 

You also must know some handy features and controls if a water softener to determine if it is for you. Characteristics and controls in any softener play a vital role in several ways. For example, you must know the options to control the amount of water, the length of regeneration cycles, and other such operations. The features and controls let you decide your cost to run your Best Water Softener 2021.

There are two methods to control the cycles; DIR and timer controls. DIR is Demand Initiated Regeneration. It’s a sophisticated method to start the regeneration when needed automatically. This process is more efficient as it does not recharge unnecessarily. It saves a lot of water and salt, without a doubt. It is a more cost-efficient method, saves you a lot of bucks. An automatic softener is helpful in the sense that it adds salt itself when needed. The other method to control cycles is by a timer. You can set the cycles manually as well.

 Water Softener Certification 

It is beneficial to know about your water softener certification, obviously. If your water softener has accreditation from the National Sanitation Foundation (NSF), it means it can wash off certain minerals from the water effectively. But the certification is not a guarantee that your device is error-free. Also, you got to check a gold seal, which indicates the quality standards of your water softener. Water Quality Association (WQA) smash this seal onto your softener, which guarantees its robust and safety characteristics.

Various Types of Water Softener

There are various types of water softener based on four characteristics. Let’s discuss them in detail so that you may have in-depth knowledge before buying a particular water softener for your house.

 Salt-free Water Softener 

A salt-free water softener is the most eco-friendly softening solution. It is also a comparatively less expensive option. It does not remove impurities from hard water literally. Instead, it prevents the formation of limescale in your hard water. It does not mean it is not a useful device. Moreover, it just nullifies the effects of those factors that give rise to hardness in your water. With a salt-free water softener, you can prevent limescale and stains. This type of water softener is perfect for those who do not want sodium in their water. This is why we do not call it a water softener but a descaler. It descales your hard water.

  • Affordable softening solution
  • Cost-efficient (because of no usage of water or salt)
  • Most eco-friendly water softening option
  • Best Water Softener 2021 for those who want a salt-free solution for hard water.
  • Prevents stains from dishes and scales from pipes
  • Does not soften the water
  • Is not as efficient as a salt-based solution, obviously

 Salt-based Water Softener 

Unlike salt-free systems, this type of water softener uses salt to solve your hard water problems. It uses the ion-exchange method for removing all the hardness-causing grains from the water. This device also uses an iron replacement method to remove iron. It is important to note that not all the salt-based softeners remove iron from your water. Mostly, with the help of the ion-exchange method, we remove magnesium and calcium grains from hard water. By water softener, we usually mean salt-based type. It uses two tanks, one with resin and the other has brine. It is the most efficient and highly functional type of water softener.

  • Affordable on the long-run but with an expensive start obviously
  • Removes hardness-causing grains effectively
  • Best water softener for those who have no problem with salt-usage
  • Does its job quickly
  • Prevents limescale buildup
  • Requires upkeep cost
  • Adds sodium in your water
  • Requires salt

 Electro/Magnetic Descaler 

The electronic or magnetic water softener is a comparatively smaller option to solve your hard water problems. You can also call it a descaler. We attach it to the pipe system, and here we go. It works like a salt-free water softener. It does not remove grains from the hard water literally. Instead, it prevents accumulation on the surface. This descaler creates a magnetic or electronic field to change the characteristics of hardness-causing grains in the water. This is not the Best Water Softener but a descaler, obviously.

  • Easy upkeep
  • Affordable and compact
  • Installation is hassle-free
  • Prevents stains and limescale
  • Gives a very slow outcome, obviously

 Dual-tank Water Softener 

You need to regenerate a salt-based water softener, mostly at night, obviously. During the process of regeneration, the device disconnects from the water system. Things get worse when you need water at night. What will you do then? What if you have a large family and water is too hard? You do not need to worry about it; a dual-tank water softener is a solution, obviously.

In dual water softener, you get two tanks to fulfill your soft water needs. You can get water during nights, or when the device is regenerating itself. You might want to get a dual-tank water softener when you have a large family. The softening system is extensive, of course. However, it solves your problem. This is the Best Water Softener 2021 for a large family. When we compare water softeners, we always look into their pros and cons, obviously.

  • Continuous water supply
  • Effective and efficient
  • Fast and reliable
  • Expensive of course
  • Needs more upkeep, increasing cost on the longer term

Water Softener Capacity Calculation

You want to get the softener to solve your hard water problems, that’s great. But every system has its limitations. A water softener is not an exception, obviously. By the way, it has its limitations related to its grain-capacity, regeneration cycles, etc. If a water softener reaches its full capacity, it needs to regenerate itself. It’s like a recharging process for the softener. If the size of your water softener is reasonable, regeneration does not matter, obviously.

Best Water Softener 2021 Capacity Calculation

Moreover, to get the right capacity, you need to multiply the number of your family members by the national average usage of water per person, which is 75. You can calculate it specifically for your family. You need to know how much water your family is going to spend per day. For example, if you have a family of four, your daily water usage will be 300 (4x75) gallons per day.

The second step is to determine the hardness in your water, obviously. You can get an idea about your water hardness. Here is how, if faucets accumulate calcium or soap scum sticks to shower walls, your water is hard. And if your skin dries, your water creates visible stains and clogs pipes; your water is extremely hard. Now you should choose a water softener according to the hardness level in your water. Higher the hardness level, the more grain-capacity your water softener should have. You can also get a test kit from the market.

Your calculations should result in grains per gallon (GPG). If they are in mg/l instead, you got to divide it by 17.1 to know the number in GPG. Here is how:

  • 150ppm or mg/l ÷ 17.1= 8.77 GPG
  • Now, have a look at this yet another formula to know grains per day.
  • Grains per day = water usage in gallons per day x water hardness in grains per gallon
  • Congratulations! You are getting better, obviously.

Moreover, you can calculate the frequency of regeneration cycles if you divide efficient capacity by grains per day. For example, if you have a family of four and ten GPG of hardness in water,

Step 1: 4 family members x 70 gallons per day = 280 gallons per day

Step 2: 280 GPD x 10 GPG = 2800 grains per day

Step 3:

    • 1 cubic foot: 24,000 grains ÷ 2800 = 8.6 days regeneration cycle
    • 1.5 cubic feet: 32,000 grains ÷ 2800 = 11.4 days regeneration cycle
    • 2.0 cubic feet: 40,000 grains ÷ 2800 = 14 days regeneration cycle

Now, you need to decide which regeneration cycle suits you, obviously. We recommend you get a 1.5 cubic feet water softener in this case. The knowledge given here equips you to choose the Best Water Softener 2021 for you, obviously.

  • Decide the available area for your well-sized water softener
  • Find your meter and cut the pipework accordingly
  • Install three valves on your pipes. Start fittings. And check if you connected them well. You need to buy tubing if the package does not have them already.
  • Connect the resin and brine tanks
  • Join the drain line to the drain elbow and the discharge pipe to the wastewater drain.

That’s all. You just installed your water softener hassle-free. Once again, we would like to ask you to give the user manual a read.
