No idea what unit to get
When I bought this unit I had no idea what size to get. I just noticed the product selection tool and should have used that to figure out what to buy. Turns out I should have bought the s38. Oh well Ill give this to my kid since she lives in an apartment

George Tuckerson –
As expected. Quick to attach.

Randall Smith –
works well!
seems to be working so far. small pieces of debris coming through the water. as far as I understand, that means it’s getting rid of my scale.
Jeremy Williams –
I like it so far. It was easy to install like they said. I called just to make sure it was on right and it seems to be working. The staff was friendly and helpful. Update later when I can see if all the scale is totally gone.

water softener
My dishes seem shinier and my hair feels better. Not sure if that is from this but I don’t really care. Thank you.

satisfied customer
I was able to install this myself when my husband was out of town so I’m calling that a win

After a few weeks I am starting to notice a difference in the hard water spots. I think the scale is coming off of the shower heads as well.
Alicia H –
We bought this when we bought our new house and we have zero hard water problems. So glad we did it right away.
Bonnie Carson –
I installed the unit last fall and I am now getting another one for my son’s house that he’s building. It’s a must-have for maintaining your home value.

I followed the installation instructions from the video on the website. In a very short amount of time, the lime rings in the toilets disappeared and the white residue in the shower was gone as well. The scale around the faucets is no longer a problem.
I strongly recommend this unit to anyone with hard water or scale issues.
Angela Biolo –
Easy to install and reasonable. Way cheaper than water softener and safer for the environment.
Robin Hansen –
I’ve had it installed for 3 months, here’s what I’ve found out for myself. i have very hard water in Colorado. Prior to installing this device, I had thick hard water spots on all shower surfaces, inside dishwasher, around refrigerator water dispenser, faucets, and those rubber things on your shower head would get clogged with white deposits, making them shoot water in all directions.
AFTER the install, white calcium deposits on shower heads and faucets are gone and they haven’t reappeared! The dishwasher cleans better, refrigerator water dispenser no longer gets the white crusties around it. Water spots in the shower and on glass are not as thick and wipe off easily.
I have had experience with water softeners, and while I won’t say this “softens” the water quite like salt, I will say that it does make a difference. A VERY cost effective difference, the water tastes much better, and the instructions and installation were very simple.
I wanted to wait a few months before I wrote this review and I hope it helps a lot of you out with your decision. I’m happy with my purchase and have already recommended this to friends and neighbors.

a little slow
It works but it takes awhile for it to work
Cameron B –
it actually reduces scale. This will not soften water. Combined with whole house filter, it seemed to do an adequate job. I previously had a Charger Salt Free Scale preventer with whole house filter in San Antonio TX. That was good, but at $2K, I was looking for more cost effective option so I got a HydroFLOW unit.

Pat Warner –
Love this!

Very good purchase
Kane S. –
Works great
I used your product selection tool it recommended the s38 but I went with this unit instead. I wish I had bought the next unit up so I could treat the guest bathroom but this one is working fine in the main bathroom and kitchen.
Ray Johnson –
We had it installed now for 2 months. No new deposit on the the sinks or dishes
A. Hale –
I was a skeptic. Calcium was clogging my boiler, and I needed to clean it out with acid twice a year to keep my hot water flowing. I installed 2 of these units, 1 on incoming water line and 1 just before boiler. Have not had water pressure issues, no cleaning out the boiler , no white build up on my shower nozzle , and no clogging of my shower head. I’m sold, still feels like voodoo, but its reduced my maintenance and it just works.
Bob Sanders –
well well worth it
Ted –
This somehow works
I am a licensed plumber, this is one of the greatest products I ever used. You make a wonderful product.
Sinjin Smith –
Perfect for my RV
Installed on my RV. It worked great! Now I don’t have to worry about the hard water messing up my RV appliances. Great investment and a better option compared to the “go” water softener.

Tankless water heater
I’m not the most mechanically inclined person and I’m not comfortable taking apart my tankless water heater to clean it. We have very hard well water at my house and I was having to get my tankless water heater professionally cleaned every 6 months. So I decided to buy one of these units 3 months ago I’ve periodically inspected it every month and so far no scale at all!
Sean Michaels –
Perfect for my apartment
I live in a small studio apartment and we have terrible water. I installed this unit 3 months ago. It was nice to see it start working immediately. All the issues I was having because of the hard water went away. Im so glad it worked because I really didnt want to use salt to make the water hardness manageable.
Patrick –
Easy install and seems to be working
I just finished installing this product. Its super easy to install so when it comes to installation this product gets 5 stars. I cant tell yet if its working so I will come back in a few months and update my review. For now, I can only give it 4 stars until I run it for a few months. So far so good.
Stewart –
First 3 months
So far Im happy with the results. Hard water crust on the faucet and water heater has dissapeared. I did add a shower head filter to help with impurities.

Tried this out on my apartment 6 months ago. Scale still appears now and then but its soft and easy to wipe up
Skip –
A+
Got rid of my water softener and installed this on my condo. So far it seems to be keeping scale a reduced level. Happy with the results so far.
Stephen –
Does what it says. I needed something that would help with scale crusting up my heaters element causing it to not heat the water anymore. Since installing it 4 months ago I havent had any scale on my element. Very happy with my purchase.
Scott Simpson –
Not big enough
Bought this and I didn’t see it wasn’t meant to be installed on an entire home. Its a point-of-use product. I upgraded to the s38 model and will update my review once I confirm it works.
Sam –
Happy
I purchased this for my condo. All the issues with scale now just simply wipe away.
Jason –
Works great on scale issues
Bought this for my Condo and I was worried I’d need the bigger unit. Its working great the scale that forms on my shower and sink just wipes away
