When we bought our first home, suddenly I cared about things I had never thought about before. Air filters, non-toxic cleaning products, and most importantly, water quality.
At first, I assumed we’d just get a pitcher filter and call it a day.
But once I started reading about drinking water quality, I realized our “filtered” water might not have been nearly as clean as I thought.
That’s when I started looking into reverse osmosis systems, which remove far more contaminants than standard filters.
After weeks of comparing systems, reading reviews, and looking at certification data, I eventually landed on Cloud RO, an under-sink reverse osmosis system designed to remove up to 99% of toxins while adding minerals back into the water.
Here are 10 things I wish I’d known about water filters & the Cloud RO sooner.
1. Most Basic Water Filters Don’t Remove As Much As You Think
Turns out, simple pitcher filters mainly reduce chlorine and taste issues. Things like PFAS, fluoride, heavy metals, pesticides, and microplastics can still remain.
2. Cloud’s System Removes Up To 99% Of Contaminants
Reverse osmosis systems push water through a semi-permeable membrane that filters out microscopic contaminants.
In fact, Cloud removes 15x more contaminants than the leading pitcher filter. That includes things like:
• PFAS (“forever chemicals”)
• Lead and heavy metals
• Fluoride
• Pesticides
• Chlorine
• Microplastics
3. Not All Water Filtration Claims Are Verified
One thing that quickly became clear is that not all filtration claims are legit.
But Cloud is NSF 58 certified for reverse osmosis systems, which is one of the most recognized independent testing standards in the industry. That means its performance and materials are independently tested to ensure the system actually does what it promises.
4. Reverse Osmosis Water Doesn’t Have To Taste “Flat”
I assumed the taste of Cloud’s filtered water would take some getting used to, since most RO systems remove minerals along with contaminants.
But the water honestly tastes even smoother and fresher than it did before.
That’s because Cloud adds essential minerals back in after purification. These include calcium, magnesium, potassium, and trace minerals, which raise the pH to around 8–9, creating clean, alkaline drinking water.
5. Traditional RO Systems Waste Tons Of Water
I was shocked when I found out that some traditional RO systems can waste up to 10 gallons of water for every 1 gallon filtered.
Cloud, on the other hand, operates at roughly a 1:1 waste ratio, making it significantly more efficient than many other systems.
6. You Can Actually Monitor Your Water Quality
At first, I thought Cloud’s smart monitoring app was a gimmick. Now I genuinely appreciate that I can track water quality and consumption in real time. Sensors in the system measure water quality at three different stages:
• tap water entering the system
• after purification
• after remineralization
For someone who likes transparency and understanding exactly what’s in their water, this feature is incredibly reassuring.
7. Filter Replacements Are Based On Real Usage
Most water filters tell you to replace them every few months, whether they actually need it or not. Cloud’s app, on the other hand, tracks your real water usage and toxin levels, then lets you know when a filter truly needs to be changed.
That feels way more practical than just guessing by the calendar, and it saves me a decent chunk of money, too.
8. DIY Installation Was Easier Than I Expected
I assumed installing a reverse osmosis system would require hiring a plumber.
But Cloud was designed for DIY installation, and the process is so simple. It took me about 30 minutes to follow their step-by-step video instructions.
9. Filter Changes Take About Five Minutes
Traditional RO systems can involve twisting large canisters under the sink – no thanks!
Cloud uses a modular filter “magazine” design that pops off so I can easily replace filters on the countertop.
Plus, the system automatically shuts off the water when the magazine is removed, making the whole process a breeze.
10. Clean Water Is a Daily Essential
Drinking water. Cooking. Coffee. Ice. Rinsing fruits and vegetables. And if you have kids, it matters even more. From filling water bottles to preparing meals, it’s something they’re consuming throughout the day.
That’s why clean water is one of the simplest and most impactful wellness upgrades you can make. The Cloud RO can produce up to 80 gallons of clean water per day, so I know I have clean water whenever my family needs it.
Final Thoughts
The Cloud RO stood out to us because it combines advanced reverse osmosis filtration, mineral-balanced alkaline water, smart monitoring, and efficient performance in a system designed for modern homes.
Now, our water tastes noticeably cleaner, and we feel much more confident about what we’re drinking every day. Looking back, I only wish I had purchased the Cloud RO much sooner.
If you’re considering upgrading your water filtration, I’d truly recommend Cloud RO.
