Description

We manufacture water softeners, whole house and reverse osmosis systems & more to provide clean, healthy water for you and your family. Aquasure was formed by industry professionals with over 25 years of experience. Our vision is to provide affordable, uncompromised quality water treatment solutions to everyone. We're set on improving the water quality for our customer's health and home. Visit the Store Visit the Store Visit the Store Engineered to deliver the best performance with 99.99% effectiveness against harmful microorganisms. Soft water is kinder to your skin and hair. Say goodbye to frizzy hair and skin irritation caused by hard water. Soft water helps extend lifespan of appliances while increasing performance and reducing energy consumption. Aquasure Water Softener comes with pre-assembled parts for your convenience, saving time and effort. Why do I need a water softener? Hard water, common in the U.S., has high levels of minerals such as calcium and magnesium causing scale buildup on pipes, appliances, and soap scum, reducing efficiency and lifespan. A water softener can remove hard minerals and prevent these issues. Can water softeners remove iron? It can remove up to 2 ppm of iron, but most water softeners are not designed to specifically remove iron. In areas where iron is more prevalent, we recommend getting the Aquasure Harmony Series with Fine Mesh which can handle up to 10 ppm of iron. Will water pressure and flow rate be affected? It can reduce the water flow rate slightly since it adds an additional step in the water treatment process. However, the impact on the flow rate is unnoticeable as most softeners are designed to have minimal impact on water pressure and flow rate. Does the Aquasure Harmony Series Water Softener work with city or well water? The Aquasure Harmony Series Water Softener is designed to remove hard water minerals from both city and well water. Well water may require further testing to determine specific minerals and potential contaminants that require additional treatment. Do I need a pre-filter for this system? A pre-filter can extend the life of your water softener by removing sediment & other minerals such as chlorine that can clog the resin beads, protecting the system and improving its efficiency.

🚀 Abunda's Overview

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


The Aquasure Water Softener System comes highly recommended by users, with the product earning praise for its ease of installation and long lifespan. Many find the controls located on the bead tank, distance from the corrosive salt water, a smart design choice. Lower salt use is also appreciated, though some users note they need to set the system at a higher grain count for more effective water softening.

Pros

  • 🔧 - Easy to install, with most units arriving mostly pre-assembled.
  • 💡 - Smart design places controls on the bead tank, away from the corrosive brine.
  • 🧂 - Uses less salt than other models.
  • 🚰 - Works well in softening water overall.
  • 💵 - Good value for the cost.

Cons

  • 💧 - May not soften water as effectively as other brands.
  • ➡ - Comes standard with a 1” hookup, which may require purchasing reducers for homes with 3/4" pipes.
  • 👀 - The brine line is solid black, making it impossible to see if it becomes clogged.
  • 🔇 - Customer support might be difficult to reach.

Should I Buy It?

Despite some minor issues, the high ratings, user-friendly design, and effective water softening make the Aquasure Water Softener System a worthwhile purchase. Whether you're a professional in the water treatment field or a DIY homeowner, this system should serve you well.


  • Good unit, good value, easy/ moderate install skills required.
Works great. Not too bad to install. I pulled out the old unit, slide this one in. It comes with a "pre-filter" thing. You'll need to have some basic plumbing skills/ experience mark the flow direction on th water pipes in and out of the old unit before you disconnect it. Take a lot of photos of the old plumbing and routing of the pipes and felx hose/pipes before disconnecting anything. All different angles and close ups of fitting, etc. Makes it easier to get your hand around it during install. Follow the directions EXACTLY. takes about 2 to 3 hours to install, program, do the initial cycle, etc. I put 120# of salt in the brine tank and filled it to the top of salt level with water using a 5 gallon bucket. I tried to do the hardness formula to set cycle interval. My math said 3500 gallons (our water is moderately to highly hard). Ran it like that and water at the faucet was hard after about 2000 gallons. I ended up just setting it to cycle every 1000 gallons. Been running now for 6 months used less than 2 40# bags of salt. 2 adults in our home. Cycles about once every 3 to 4 days at 1000 gallon usage during that time. I like the unit. Pretty easy to program and adjust. I recommend it. I'd say it's a 3 out of 5 skill level to install where a 5 would be completely plumbing a bathroom sink, shower and toilet. 1 would be replacing a sink drain trap and a 2 would be changing out an existing bathroom faucet. You'll need some plumbing skills for sure, but it's doable. I hate working with plumbing. I always seem to have little tiny leaks at my threaded connections. It's frustrating, but usually just requires tightening or taking it back apart and putting more thread tape on the threads. Anyway, you get the idea. If you've done lite plumbing work before, you'll be fine. If this is your first plumbing project, get some help from a buddy with experience are higher a plumber. If your going to higher a plumber, talk to them before you order the unit. They may have their own brand that the favor. Some plumbers can be opinionated and may have some valid advice on purchasing certain brands. My plumber, for example, doesn't like AO Smith. He said he gets calls all the time from people who have units 3 years old with problems already. He said dont buy the AO Smith from Lowes (which was what I was going to do). ... show more

  • Surprisingly DIY-able, well made. Immediate result was worth it Surprisingly DIY-able, well made. Immediate result was worth it
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

  • Wow! I FINALLY have soft water!
I bought this water softener to replace a deceased "schmulligan" softener. It was way less expensive than going with the big name guys. So easy to install. It really is a "plug in and play" type of unit, if you've already had one installed. The instructions are clearly written, short, and super easy to follow. I followed the directions step by step and within 24 hours, my water went from 450 ppm to less than 25 ppm. I did have a little help. My husband brought the resin tank downstairs using a dolly. It is quite awkward to carry and quite heavy too. Once it was in place and ready to rock and roll, I calculated how many gallons of water we used (average American used approximately 75 gallons a day) multiplied by how many people are in the household and used that as a baseline. AquasureUSA.com has a calculation section on their website and I just used what was recommend. Set the control valve with the proper time, how much soft water we needed and just walked away. I did purchase two 1" FIP to FIP stainless steel flex hoses and two brass male connectors to attach my whole house filter just before the softener to filter out a whole bunch of gunk prior to the intake valve. It was basically just wrapping plumbers tape around the fittings, attach said fittings to the water intake and outlet, attach the brine tank hose and discharge hose, plug in the control valve and run it. I am not a plumber. I am a 63-year-old disabled woman who is not afraid to try, so you CAN do it too. Just read the instructions completely through, get a Philips screwdriver/socket wrench (my personal choice), a Plumbers wrench, an adjustable wrench and your patience. Wrap about 7 spins of the plumbers tape (in the correct direction - clockwise) attach female hose to the male fitting, tighten connectors firmly and turn your water back on. Super easy. Time consuming, but not hard. If you can turn a wrench, you can do this. CAUTION: The valve control head, (the thing on top of the tank) is made of plastic. Be careful about cross threadding and over tightening. You certainly don't want to do that. Make sure you lube the O-rings, which will be included with this purchase. One final note: Thank you Aquasure for the whole house filter. It was truly a pleasant surprise. That too was a simple install. My water is clean, clear and soft! Very, very happy with this purchase. I would highly recommend this unit! Thanks again Aquasure!! ... show more

  • Close to perfect whole home water softener, just a couple quirks to shout out Close to perfect whole home water softener, just a couple quirks to shout out
First off, after the initial flush and regen, this 48K Grain whole home softener does it's job VERY WELL. Assembly was not bad considering, directions are laid out and with font that I could actually read. I would purchase this unit again, of course depending on the longevity I can get out of it... which would be destemmed hopefully way down the road. I would like to point out, everything in the 2 boxes completes your unit (even silicone grease) except a 1/2" ID poly tube; used for overflow protection in the brine tank. This is noted as optional in the directions, I believe I will purchase this tubing and install it as if the float inside the tube fails, I could have a salt slurry mess all over my laundry room floor. My two quirks or negatives are: 1. Programming is several pages long (in the instructions), it's laid out (with images) but I don't think it needs to be this complicated. Related to this problem is the display panel. It's 30 year old LCD technology, having blocked out letters or hard to intemperate lower case letters. The upper case are fine, still an old display that could meet an updated one and the Mfgrs cost would not be that significate. SEE MY IMAGE of the head, I made a "Cheat Sheet" to help me (years down the road?) when I may need to re-program, or, having to quickly click maybe the "Cancel Regen". I will try to keep the instruction manual in a poly bag taped to the wall by the tank. 2. While unit is regenerating, IT IS LOUD!. Sounds like Niagara Falls lol. I know from experience, some of this noise comes from the turbine device that counts the Gallons (or Liters) being used. I have an LED faucet that is noisy because of this, but not nearly to the extent of this unit, If your softener will go in the basement, then you may be fine. Unfortunately, out Laundry room is close to our master bedroom and the timed 2am (or I went with 4am) regen is an awakener. ... show more

  • Technical issues, hard water problems, will be replacing soon
Size: 32,000 Grains
Problems, problems, problems. We installed this during a house expansion/remodel last year to replace an older GE model that worked fine, but was getting old. Aquasure was easy to install and the instructions are fairly clear, though the control screen display and prompts are very clunky and not intuitive - you definitely have to keep the paper manual on hand to understand how to set it up and change settings. One side note: some reviews mentioned the clock resets during a power outage - I never had that issue - it always kept time regardless of the power going out (though we never had a long, multi-day power outage, just short ones). Once we got it up and running, it worked great for about 6 months. Then we noticed that hard water would show up at the tap when there was still a few hundred gallons left on the countdown meter (the meter that starts a recharge cycle). Over time, I lowered the recharge gallon amount, but each time, hard water would show up with a few hundred gallons left. I started by setting it at 3,150 gallons (based on the calculation in the manual - using a scientific water quality sample as my data input) - which worked for 6 months. Once the hard water problem showed up, and I started reducing the meter point by a few hundred gallons at time (3150, 2700, 2250, 2000...etc.) I ended up at 1,000 gallons and then started getting hard water with 200 gallons left to go (hard after 800 gallons went through the meter). I spent hours on the phone with customer support over days and weeks. They eventually shipped me a new resin tank. I installed that, cautiously set the meter to 2,500 gallons (manual still said 3,150 would be the right amount, but I was gunshy and wanted it to work this time so I set it more conservatively). After a few cycles of working fine, sure enough, on this last cycle, I got hard water with 400 gallons left to go - had to go back to manually cycling after I catch hard water at the tap. Now I'm back to watching the meter every few days, using test strips at the tap, trying to catch the hard water before it ruins my expensive water heater and faucets. This thing is taking up mental space in my head which is not what I want from an appliance that should be reliable. Their customer support was courteous and responsive. However, they were not able to answer some of my technical questions. Like why does the meter setpoint calculation have an additional factor based on # of people in the household, instead of a simple and pure # of gallons throughput? The rep also told me at one point that the system has to cycle once per week (then why have a gallon throughput calculation? And if there is a time component, what is that based on? Do beads degrade over time regardless of usage throughput?). My old GE system cycled once every few months and I never had any problems with nor any hard water. With this system in its degraded state, I am cycling once per week - which is eating a lot of salt (more $$$). While I appreciate that customer support spent time troubleshooting with me and even shipped a replacement tank for free, this system is inferior and I have had too many problems with it. I will be replacing it shortly, tired of spending time trying to monitor and manage the hard water issues. ... show more

  • This Aquasure Harmony water softener surpassed my every expectation! This Aquasure Harmony water softener surpassed my every expectation!
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
