It builds up on your scalp and causes dry hair, split ends, and even hair loss.

"Great Product with Great Service!"

I purchased this a year ago and have waited to have a good timeline in which to use it. All I can say is how very pleased we are with this softener. It was reasonably priced and has proven to be a terrific investment. The Aquasure arrived in extremely secure packaging, quickly, and safely. Once I was ready to install the unit it was easy to hook up, program, and start the first regeneration.

"Not your big box store water softener."

2 weeks since install:I had researched water softeners for some time and came across these on Amazon. Ratings for the Aquasure line were high and most of the feedback was positive.I installed the water softener myself after receiving it. So far very happy with the product and the quality of materials provided.

"Works perfectly!"

I live on a well water system with 44 grains of hard water per gallon. I installed this system with flex water lines to make it easier. total setup took maybe an hour. The hardest part was moving it because it was heavy. After I installed the system, It dropped my grains per gallon to less than 1. Yes, I would recommend this to a friend.

"Color me impressed."

We have had a $4000 General Ionics system about 20 years ago that was awesome and I would definitely compare this one to the $4000 system we had years ago. I am simply amazed at how soft our water is. My husband built our house so installing the system was nothing for him so I can’t speak to the installation but the functionality is way more than I expected for the cost.

"Very economical for it’s size and capacity"

Wow……this is truly a great unit. Things arrived packaged well; the unpack was easy and the installation as well as programming instructions were crystal clear.

"Efficient and priced right"

Great water softener. We bought it to replace our old one that finally quit working. This one works so much better than our old one ever did. It allows us much more water pressure and seems to use the salt more efficiently. It was also very reasonably priced. Completely satisfied.
