Top Amazon Reviews

🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.


These reviews commend the Harmony Water Softener for its practical design and good performance, with its setup process deemed as relatively straightforward. It seems to be a durable and efficient unit that operates by using less salt than many other products on the market. However, a concern expressed by several users revolves around its slightly lower than desired softening power and the oddly sized pipe connectors.

Pros

  • 👍 Easy and convenient to install
  • 👍 Robust design keeps electronics away from the corrosive brine tank
  • 👍 Uses less salt compared to other units
  • 👍 Durable and designed for longevity

Cons

  • 👎 Softening power could be better and might need a higher grain count setting
  • 👎 Comes with 1” inch hookup, which might require an additional step to fit the common 3/4" pipes
  • 👎 The brine line is black and opaque, hide the visible confirmation of possible clogs

Should I Buy It?

Overall, if you need a powerful water softener and are willing to tweak the settings a bit, the Harmony Water Softener might make a good investment. It seems reliable, sturdy, and is designed to last long. Though it has a few minor drawbacks, the positives seem to outweigh the negatives, making this a worthwhile consideration for your home's water treatment needs.


  • Surprisingly DIY-able, well made. Immediate result was worth it
Size: 48,000 Grain
I recently purchased and installed the Aquasure Harmony Series 48,000 Grain whole Home Water softener with their pre-filter and as of day 1 I am very happy with the purchase. I will be sure to update this review if anything changes. Overall, This is a great deal and the DIY aspect of it is very manageable. I've been advertised whole-home water filtration and water softening as well as having used it at my parents and siblings homes. I couldn't stomach the quotes I received from professional installers and had been warned by my parents to be careful about parts as their system is proprietary and they have to call out a company rep to install the replacement filters. Aquasure seemed to check my boxes and had enough good reviews that I was willing to take the risk at this price point. Installation: Overall, I'd say it was a 2.5 out of 5 on difficulty and that is mostly due to this being the first time I've ever worked on plumbing. This difficulty rating would be greatly reduced (or increased) depending on how your home is setup and how your existing water pipes are laid out. This system is quite large and my water came in next to some concrete steps in my garage - as such I had to install it on the lower level and still plumb it up to the top of the steps where my water heater and rest of the home is plumbed. I opted to use Sharkbite fittings, 3x 1" FIP water heater hoses, and some copper pipe from my local hardware store & fittings purchased on amazon. Assembly of the Water softener system was not difficult at all and was very straight forward, the difficult part was tying it into my water pipes and specifically my biggest challenge was creating a proper drain for the regen cycle of the softener. The regen takes about an hour and 15 minutes and put out a LOT of water during the initial flush so be ready for that. Again, the assembly of the softener itself was very straightforward and easy but hooking it up to my plumbing was a bit challenging due to tight quarters, un-even surfaces, and it being my first time working with plumbing or sharkbite fittings. I'd estimate I spent close to $120 in additional supplies and tools to finish this install. Performance: So far so good, It has only been a day but my laundry came out softer, my water tastes better, and my shampoo in the shower and shaving cream both lather much better. My house is older and had a lot of scale and buildup on fixtures and appliances and I am glad to be preventing more of that from appearing in the future. After I get my first few salt refills I'll be sure to comment on about how long the 80lbs of salt lasts me but it is thankfully very cheap and easy to replenish. Final thoughts: I'm already happy with this purchase and will be recommending it to others. I hope it lasts a long time to come. The product seems well built, the documentation and accompanying installation video were very good and didn't leave me guessing or lost. Everything seems well thought out and appropriately built. I kind of wish the softener outlets came out at 90 degree angles so I could push it closer to a wall but I am making due with flexible hoses. If you can take your time, plot things out, and aren't scared of buying a pipe cutting tool - this is very doable as a DIY'er with sharkbite fittings and 1" hoses. The effect of it on my water was immediate and noticeable, I think the benefits far out weigh my afternoon of putting this together and will pay dividends on my quality of life for years to come. ... show more

  • This Aquasure Harmony water softener surpassed my every expectation!
Size: 48,000 Grain
I am truly bewildered at how efficient Aquasure Harmony is! Prior to installation, I had a water hardness of between 250ppm and 350ppm. After installation, the water hardness was almost non-detectable, being somewhere between 0 and 25ppm! That reduction of water hardness is incredible. We purchased the 48,000 Grain model so we will not have to regenerate until 3100 gallons have been used. In the picture you will notice that water is traveling from left to right. First, the tall tank at the far left is a very sophisticated filter that removes the majority of impurities. The next filter is located between the two tall tanks and is the small pre-filter that came with the Aquasure Harmony. Finally, the third tank is the ion exchange from Aquasure that softens the water by removing calcium and other heavy metals. The results of this type of water treatment shown in the picture using both filtration and ion exchange is ideal which results in the purest water attainable with today's technology. But just as one car is not the same as another car, so too are ion exchanges not the same. Aquasure Harmony's ion exchange water softener is by far the most impressive and most efficient water softener that I could have ever imagined, including the separation of the salt container to be by itself to avoid salt water corrosion of other parts! We discontinued use of another water softener years ago because of the taste of salt we had in the tap water of the house. But this water softener does not only produce water that is virtually zero ppm of "hardness", but the taste is smooth, pure, saltless, and absolutely magnificent. If there is any residue of salt in the tap water, we have never tasted it because it's concentration is so low as to be totally unnoticeable to the most demanding taste buds! I am writing this review because I cancelled my purchase one day after buying it via Amazon. I cancelled because I thought, "Why go back to a water softener that uses salt, when I know it will make the tap water salty?" But then I read more reviews and most people did not have such an issue as salty tap water. So I decided to give it a chance and decided to cancel my "return status". The tap water is phenomenal and I am very glad I decided to keep this water softener to give it a chance. It has truly surpassed my expectations! One last comment before I end this review. I read a lot of reviews where the customer experienced leaks. I experienced no leaks whatsoever. Make sure you apply silicone grease to ALL O-rings, and take your time in the installation of parts so that they are installed according to the instructions. Thank you Aquasure Harmony for an outstanding product! ... show more
