### 3/5 — Niche product. Expensive filters.

*2025-11-28*

Water tastes good. Filters need to get replaced annually for $200. We’re right at 580 gallons. The product itself doesn’t actually measure contaminants, just grabs local data from public water systems. They measure the total dissolved solids before and after. It’s better off getting a 2 stage entire house system than replacing the filters + battery for this thing yearly. 

Step above a Britta! Fine for if you have an apartment.

### 1/5 — Smoke and mirrors

*2025-05-23*

Unit is sleek and tech is alluring, but there is a large amount of inconsistencies in the tech. Nothing syncs, or is accurate. Says I need to replace the battery, but when I go into the details it says it’s good for another year, yet our water smells like sulfur.

### 5/5 — Top Rated

*2025-02-01*

This system was thoroughly and thoughtfully put together!

### 5/5 — App name not good

*2024-08-25*

You guys need to change the name of your app. “Cloud” is way to vague and I’ll never find it. Cloud RO? Cloud Water?

### 2/5 — App is not working

*2024-07-11*

Hello we just installed the system and downloaded the app however when we enter the email, the screen stays a dark blue. How do we resolve?

### 5/5 — Great!

*2024-04-17*

Great product!

### 5/5 — Best water filter out there

*2024-04-09*

Super intuitive app. I love being able to see that it’s working and how much I’m drinking.

### 1/5 — Can not connect

*2024-01-28*

Can not connect to application if your purchase this RO filter through Amazon. Will adjust review once they get this issue sorted. Super bummed currently.

### 5/5 — Great product!!!

*2023-03-17*

I love is product. I never knew what my system was doing or the condition of my filters. Just by looking at the app, Now I know my filters are clean and when they need changing. A dirty filter can be worse than having none at all so now Im confident the water I’m drinking is 100% clean. Installation was super easy and everything worked just fine right off the bat.

### 5/5 — Simply the best

*2023-01-25*

It’s the blue label of water, the finest available
