If you've been following me for a while, you know I'm always trying to make healthier choices for my family-especially when it comes to what we eat and drink.
For years, I didn't think much about our tap water. If it looked clean, I assumed it was fine.
But after learning more about contaminants that can be present in drinking water-including lead, PFAS ("forever chemicals"), microplastics, chlorine, pesticides, and other impurities-I decided it was time to upgrade our filtration system.
After comparing several options, I ended up installing the Cloud RO, and I'm genuinely impressed.
Here's my honest review after using it in my own kitchen.

Why I Chose Cloud RO
We already had good-tasting tap water, but after reading more about PFAS, lead, microplastics, and other contaminants that can be present in drinking water, I wanted an extra layer of protection for the water we drink every day.
Since I spend so much time cooking, we're constantly filling glasses, coffee makers, kettles, reusable water bottles, and large pots for pasta, rice, and soups. Water is one of the most-used ingredients in my kitchen, so investing in better drinking water felt like an easy decision. Check the prices here.
What Is Reverse Osmosis?
If you're new to reverse osmosis (RO), here's the simple explanation.
Reverse osmosis is one of the most effective water filtration methods available. It works by pushing water through a specialized membrane that removes many common contaminants, including lead, PFAS ("forever chemicals"), chlorine, fluoride, pesticides, heavy metals, and microplastics.
The result is cleaner, better-tasting water for everyday use.
One thing to know is that traditional reverse osmosis systems also remove naturally occurring minerals. That's why I specifically wanted a system that filtered thoroughly without leaving the water tasting flat-which is one of the reasons I chose Cloud RO.

Why I Chose Cloud RO Over Other Reverse Osmosis Systems
I spent quite a bit of time comparing different reverse osmosis systems before making my decision.
Cloud RO stood out because it offered everything I was looking for in one system:
- NSF 58 certified for reverse osmosis performance
- Remineralizes the water with calcium and magnesium after filtration
- Smart app that tracks water quality, filter life, and usage
- Compact under-sink design that doesn't take over the entire cabinet
- DIY-friendly installation with clear instructions
- Modern, minimalist design
For me, it wasn't just about removing contaminants-it was about finding a system that fit seamlessly into everyday life.
Installation
I'll admit, installation was the part I was most nervous about.
Thankfully, it was much easier than I expected.
The instructions are clear, everything is well labeled, and the unit fits neatly underneath the sink without taking over the cabinet. Once it's installed, it's completely out of sight, so your kitchen still looks exactly the same.

How We Use Cloud RO Every Day
Since installing the system, we've completely stopped using water pitchers and bottled water.
Every day we use it for:
- Drinking water
- Filling reusable water bottles
- Morning coffee
- Tea
- Cooking rice
- Boiling pasta
- Homemade soups
- Washing fruits and vegetables
- Filling pitchers when guests come over
Having filtered water instantly available from the faucet is incredibly convenient. There's no waiting for a pitcher to filter or remembering to refill it.

What I Like Most
The Water Tastes Better
This was honestly the biggest surprise.
The water tastes noticeably cleaner and crisper, and because Cloud adds calcium and magnesium back after filtration, it doesn't have the flat taste that some reverse osmosis systems can have.
I've even noticed that coffee, tea, rice, and pasta taste better.

Excellent Filtration
One of the biggest reasons I chose Cloud RO is its filtration performance.
According to the manufacturer, it helps reduce:
- PFAS ("forever chemicals")
- Lead
- Fluoride
- Chlorine
- Microplastics
- Pesticides
- Pharmaceutical residues
- Heavy metals
That gives me much more confidence about the water my family drinks every day.


Smart App
The Cloud app monitors water quality, filter life, and usage in real time.
Instead of guessing when filters need replacing, the app lets you know exactly when it's time.
It's one less thing to remember.

Low Maintenance
Another thing I love is how easy it is to maintain.
Changing the filters takes about a minute, and you don't need a plumber or special tools.
Simply replace the filter when the app reminds you.
Compact Design
This may not seem like a big deal, but I love that everything stays hidden under the sink.
No bulky countertop filter.
No pitcher taking up fridge space.
Just clean drinking water whenever we need it.
Pros
- Excellent-tasting water
- Removes many common contaminants
- Remineralizes water
- Compact under-sink design
- Quiet operation
- Easy filter replacement
- Smart app monitoring
- No countertop clutter
Cons
- The biggest downside is the upfront cost.
- It's definitely more expensive than buying a basic pitcher filter, but considering how often we use it every single day, I see it as a worthwhile long-term investment.
Is Cloud RO Worth It?
For me, absolutely.
Clean drinking water is something we use every day, and this is one of those kitchen upgrades that quietly makes a difference. Whether I'm developing recipes, making coffee, filling a water bottle before heading out, or simply pouring a glass of water with dinner, it's something I use constantly.
If you're already considering a reverse osmosis system, I think Cloud RO strikes one of the best balances between filtration performance, convenience, and design.
Where to Buy
Cloud RO is currently running a limited-time sale, making this a great time to upgrade your drinking water.
Frequently Asked Questions
It depends on your rental agreement. Since the system requires installation under the sink, you'll want to check with your landlord before installing it.
Yes. According to Cloud, the reverse osmosis system is designed to significantly reduce fluoride during the filtration process.
Yes. Cloud RO is designed to reduce PFAS ("forever chemicals") along with many other common drinking water contaminants.
Yes. It helps reduce chlorine, which also improves the taste and smell of your drinking water.
Like all reverse osmosis systems, some wastewater is produced during filtration. However, Cloud RO has a much more efficient water-to-waste ratio than many traditional RO systems.
Absolutely. The water tastes noticeably cleaner and crisper. Because Cloud adds minerals like calcium and magnesium back after filtration, it doesn't have the flat taste that some reverse osmosis systems can have.
The remineralization stage naturally raises the pH slightly, producing mildly alkaline water.
Yes. Cloud RO uses electricity to power the system and its smart monitoring features.
Not at all. You'll hear the system briefly while it's filtering, but it's very quiet and not something I've ever found distracting.
That depends on how much water your household uses. The app tracks your usage and lets you know exactly when it's time, instead of relying on a fixed schedule.
If you're comfortable with basic DIY projects, yes. The instructions are clear, and installation is straightforward. If you'd rather not do it yourself, any handyman or plumber should be able to install it without any issues.
