Dealing with hard water and the buildup that it can leave behind can make you hate using water because of how often you need to clean.

Thanks to the Eddy Water Descaler, you have an alternative to traditional water softener systems. Designed to work on the deposits you already have and to prevent buildup in the future, it includes a 12-month money-back guarantee. Find out what shoppers love about this product in our Eddy Water Descaler review.

Detailed Review and Breakdown

Many shoppers looking for a salt-free water softener alternative turn to Eddy and products such as this descaler. Now is a good time to look at our review to see the specs of the product and its overall reliability.

Top Features

You cannot look at the Eddy Water Descaler without taking a look at the guarantee offered by Eddy. This guarantee lets you get your money back if you aren't happy up to 12 months after your initial purchase. You also receive a lifetime warranty that covers any of the repairs or replacement parts that the descaler might need.

We also like that it includes all the supplies that you need for installation and that you can install those parts in less than an hour. You just need a nearby outlet for the power source. It can significantly improve the efficiency of your home's plumbing system.


  • Measures 6.69 X 1.57 X 3.54 inches
  • Weighs 7.8 ounces
  • 110 volts/5 watts
  • 12-month money-back guarantee
  • Compatible with most types of pipes
  • Offers a 20 GPM flow rating or higher

Ease of Use and Reliability

One issue we had with the Eddy Water Descaler is that it requires some general maintenance that you cannot do yourself. Some of the parts do not come off unless you have the right tools. That maintenance can add to your total operating costs in the future.

In terms of reliability, we give this salt-free alternative two thumbs up. Most people who used it found that it worked well and that they saw improvements quickly. It gives you a high flow rating and works with water that has various hardness ratings.


If you want to bring home this descaler, you'll likely find yourself surprised at the low price. Though it does cost more than some of the alternatives that you can learn about below, Eddy helps you save money on the installation costs and the cost of maintaining the descaler later.

Who is This for?

The primary people that this electronic descaler from Eddy can help include those with hard water and those who see spots on their fixtures and faucets. Those spots form because of the lime and other impurities in the water, which can cling to everything from glasses and dishes to shower doors and floors. Eddy promises that it will eliminate the deposits in the water that cause those spots.

We also recommend this descaler for those who suffer from dry hair that resembles straw and anyone who suffers from dry or itchy skin, especially in the winter. Once you install the Eddy system, you might notice significant results and improvements in the next few days.

Our Opinion

Only after trying this product did we create our Eddy Water Descaler review. This is an electronic descaler that works in most homes and can change the hardness of your water and give it the soft and smooth consistency that you want. It lets you remove calcium and other scale buildups from your pipes and keep that scale from causing more buildup.

Thanks to the 12-month money-back guarantee, you can return your purchase for a full refund up to a year later, which is significantly longer than other companies give you. We also think it's worth the money for the lifetime warranty that covers so many of the issues you might experience.

Other Options Worth Looking at

Eddy isn't the only company that offers salt-free alternatives to traditional water softeners. You may want to consider the iSpring ED2000 Whole House Salt-Free Electronic Descaler Water Conditioner, which doesn't need any special maintenance and works on PVC and any of the other pipes you might have. It costs close to half what the Eddy Descaler does too.

Another product that might appeal to you is the HQUA 5000E Electronic Water Descaler. It has a similar design to the Eddy descaler and is nearly as easy to use. It only works in homes with a water hardness of 25 GPM and is not compatible with pipes that are more than 1.5-inches thick. Two other units that you may consider are the Bullet Poly Softener and Magnetic systems inexpensive units. They are simple to use and install.
