And you need not worry about essential minerals being removed from the water as this descaler only treats unwanted materials and preserves vital minerals. 

What’s more, we had cleaned the mineral build-up from faucets and showerheads before installing this product, and there has been no build-up for the past few months. This proved that it actually works well, and we were indeed impressed. 

What Could've Been Better?

It is best if you check the level of deposits that are present in the water before making a purchase. The decaler does not work with very hard water, and you will see some amount of build-up in such cases. Now, this is a drawback, but it provides enough value for its price if you use it well.

Why Did We Like It?

To begin with, this product works very well with hard water, and you can take care of water with its 10-19 grains per gallon. We saw a gradual change in the water quality over the first few weeks, and our shower would not get clogged anymore. Also, soaps started lathering better, thanks to this. 

Furthermore, it makes water suitable for those with salt-restricted diets by reducing the levels and preventing excess salt from being present in the water. It is great for skin and hair too, and we noticed that the hair felt softer after this was installed. 

Now moving on to the installation process, it can be done without any professional help. You can finish it off within half an hour if you have prior knowledge about the process. Otherwise, you can watch tutorial videos before proceeding. 

What Could've Been Better?

The tech support team was disappointed as they could not answer some very fundamental questions. We were initially unable to get through to them, but when we did, they were not able to solve our queries. So, we had to take to the internet to find answers but we hope that the brand looks into this. 


  • Prevents scale build-up inside pipes
  • Known to bring down energy-consumption
  • Promotes healthier hair and skin
  • Works on all kinds of pipes


  • Inefficient tech support team

3. Yarna CWD24 - Best for Rust Accumulation

  • WHO BENEFITS FROM YARNA: Our customers report cleaner pipes...

Why Did We Like It?

This product treats water with the help of electric impulses that are controlled by a microchip, which is computerized. It then leaves electric impulses, which are transferred via ultra-flat impulse bands that are tied around the pipe. This, in turn, prevents crystals in the water from sticking to each other, and if they do not stick, then no deposits are formed. 

Now, if you are worried about essential minerals like calcium and magnesium being removed from the water, rest assured that will not happen. This one does not eliminate needed minerals and focuses on preventing mineral build-up in pipes and other faucets and sinks. 

Plus, it works with all pipes, which are 1 inch thick, and you can attach it with PVC, plastic, copper, iron, stainless steel, and PE-x compound pipes. The installation process will only take 15 minutes, and you can easily get it done yourself. 

What Could've Been Better?

The only problem we had with the descaler is that the copper bands were slightly oxidized. Now oxidation minimizes the conduction power of electricity, and hence we wanted to exchange it. The customer service representatives were nice enough to allow it without any hassle. And the next one worked fine and had no visible damage. 


  • Helps in dissolving lime build-up
  • Works with all kinds of pipes
  • Preserves calcium and magnesium
  • Easy to install


  • Oxidized copper bands

Preserves Minerals: Yes | Dimensions: 5.9 x 1.8 x 2 inches | Weight: 1.39 pounds | Suitable Pipes: Works all kinds

Some of the major problems that happen due to lime build-up are corrosion, rust formation, and bad color and smell of water. Now, this product targets all of this by not letting build-ups form and by descaling the water. The pH level of the water is not affected, and that is a great benefit. 

Moreover, this takes care of hard water up to 25 grains per gallon, and you can rest assured that there will be a change in the quality even with very hard water. Plus, it works with all kinds of pipes, and you will not need a plumber to attach it to a pipe. This is a quick job, and it will take you 5 minutes at the most. 

Coming to customer satisfaction, HQUA is very particular about it and offers a money-back guarantee for up to 365 days. If you are not satisfied, just contact them, and they will arrange for a replacement. 

What Could've Been Better?

While this will be providing you with impressive results, it will take time. You can expect to see some changes over 3 months of use and slowly the water quality is improved. Now, if you wanted an immediate solution, this might prove to be a major drawback.

Next, the product is known for low power consumption, and you should not be seeing a major change in your electricity bills. This features a working voltage of 9V and a power consumption of 0.5 W. 

Moreover, this will create a magnetic field with the help of coils that will lead to the crystallization of mineral ions. That will ensure that minerals do not stick and clog faucets and instead flow with the water. 

What Could've Been Better?

This product works well with water with hardness ranging from 10.5 to 12.5 GPG. That being said, it will not work on very hard water, and you will see lime deposits in such cases. Hence, we would recommend checking the number of grains per gallon of water before proceeding.

Plus, it provides a healthier and less expensive alternative to water softeners. Water softeners waste lots of water when they are eliminating chlorides, and they need regular maintenance. This one is not as expensive and you will not have to go above your budget at any rate.

What Could've Been Better?

This product runs with the help of 1 AAA battery, which is unfortunately not included in the pack. You will have to purchase it separately, and it is best if you get one from before.

Moving on, this model is perfect for hard water up to 30 grains per gallon and 598 ppm of calcium. You can easily install it on any kind of pipe up to 1.25 inches in diameter, including PVC, PEX, CPVC, and copper. 

And it is 8.8 x 5.5 x 4.4 inches in size and fits into small spaces easily. Since pipes are generally present in restricted spaces, this will prove to be beneficial. 

What Could've Been Better?

The only problem we faced was with the installation process, which was time-consuming. You will have to first measure the width of the pipes and then read the instructions about how much wire you will require to double wrap. The wires need to be wrapped around the pipe, and they kept getting tangled, which had proved to be frustrating. 


  • Can be installed on vertical and horizontal pipes
  • Works with homes up to 5,000 square feet
  • Compatible with CPVC, PEX, PVC, and copper pipes
  • Improves durability of appliances that use water

Plus, this works with all kinds of pipes including, stainless steel, galvanized, PVC, copper, and PEX ones. You can easily install it yourself with some guidance from the company or the internet. 

And do not worry about losing out on essential nutrients as this will not prevent calcium and magnesium from reaching you. So, this process does not involve removing any of the minerals, but they are treated so that they do not get deposited in faucets, showerheads, and sinks. 

Moreover, if you are on a salt-restricted diet, this will ensure that the water is well-treated and made fit for you. This product will also lead to healthier hair and skin, both of which are important. 

What Could've Been Better?

While we did not face any issues ourselves, on reading numerous reviews, we found that some customers complain that the product could not be returned after 30 days of buying it. Now, this can be problematic if it does not work well with the water in your area. Hence, it is best to discuss this with the customer care representatives before proceeding.

Buying Guide For The Best Water Descalers For Hard Water

Now that you know about the top 8 water descalers, you must have noticed that they all come with certain differences and similarities. In this section, we will be discussing the key considerations to keep in mind before making a choice. 

These are important considerations, and they talk about the major differences in the products mentioned above.


None of us want to pay a huge sum of money for maintaining the product that we choose. Now, most water descalers do not need you to spend on maintaining them, but you should check the description well for any hidden clauses. Read about any subsequent costs that may come up and how much effort is involved in the process before proceeding.


While most descalers are easy to install, it is best if you do your research before purchasing. Now, if you have installed one before, this should not be a problem at all. 

For those who are doing it for the first time, the process can be slightly tricky. We will recommend that you read the feedback and the experiences of other customers before purchasing. Some brands will have customer care representatives helping you out over the phone, while in other cases, online videos can be the guide.

Grains Per Gallon

The level of minerals in the water defines how hard it is, and it is essential that you know it in your case. If you are not already aware of it, ask a plumber or call up the local water department to know the grains per gallon. 

Having said that, some products will work well with water with up to 15 GPG while others can extend up to 25 GPG and beyond. Be careful about this as if you have very hard water and the machine is unable to descale it, then the entire purpose gets defeated.


While these are generally small in size, you still need to measure the space available and then compare it with the size of a product that you like. So, you will be attaching it on pipes, and pipes are generally present in restricted spaces. 

While many forget to consider this beforehand, you do not want to go through the entire process of returning and purchasing another. Hence, size is something that is best not ignored.


Many consumers who use water descalers have returned them after a few months because they did not suit the water in their area. They were able to do that because the product had a 100% money-back guarantee for a limited period. 

The moral of the story is that it is safe to purchase a product that comes with a 6-12 months warranty period. This will ensure that it can be returned if you are not satisfied or it is not working well with the water. 

Water Descalers For Hard Water FAQs

  • Do water descalers require regular maintenance?

    Most water descalers do not require regular maintenance. However, it is important to read the product description carefully to check for any hidden clauses regarding maintenance. Look for information on subsequent costs and the level of effort involved in the maintenance process.

  • How easy are water descalers to install?

    Water descalers are generally easy to install, but it’s recommended to do some research before making a purchase. If you have prior experience installing descalers, it should not be a problem. For first-time users, it can be slightly tricky. Reading customer feedback and experiences can be helpful. Some brands provide customer care support over the phone, while others offer online videos as installation guides.

  • What is "grains per gallon" and why is it important?

    “Grains per gallon” (GPG) refers to the level of minerals in the water, which determines its hardness. It is crucial to know the GPG value in your water to select an appropriate descaler. You can consult a plumber or contact your local water department to determine the GPG level. Different descalers are designed to handle varying GPG ranges, such as up to 15 GPG or even higher. It’s important to choose a descaler that can effectively handle the hardness of your water to achieve the desired descaling results.

  • Is a warranty important when purchasing a water descaler?

    Yes, it is recommended to choose a water descaler that comes with a warranty period, typically ranging from 6 to 12 months. A warranty provides assurance and allows you to return the product if you are not satisfied or if it doesn’t work well with your water. This ensures that you can seek a refund or replacement within the specified warranty period if the descaler doesn’t meet your expectations or compatibility requirements.

    If you do not want to use a salt-based system, this is the best alternative on the market currently. A good water descaler will bring in a major change in your life, and you will be able to see it within a month. 

    Having said that, let us move on to our favorites now. The Eddy Water Descaler ED6002P-US is our topmost choice as it ranks high in efficiency. But if you have very hard water in your area, the iSpring ED2000 Water Descaler System is going to fit in excellently well. 

    On the other hand, the Yarna Water Descaler System CWD24 deals very well with rust and bacteria. 

    With this, we have reached the end of this comprehensive guide, and we hope you have all the needed information now. Let us know about any further queries that you may have in the comment section below.
