30 Days with a Water Filter That Changed How I Think About Every Sip
I’ve always considered myself a health-conscious person. But somehow I never gave a second thought to what was actually in our water.
We had a pitcher filter, and it seemed fine until my best friend looked at it and said, “You know that’s not actually filtering much, right?” What followed was a twenty-minute conversation that really opened my eyes.
This is a diary of the thirty days after I installed a Cloud RO reverse osmosis system under my kitchen sink in Los Angeles.
Day 1
The installation took less time than expected
When the Cloud RO box arrived, I assumed it would sit in our living room for two weeks until my husband finally got around to installing it. But I was too excited to wait.
So I watched Cloud’s installation video. Thirty minutes later the system was mounted under the sink. It was easier than building my son’s legos.
I poured my first glass and took a sip. It tasted like pure, refreshing water.
Most RO systems strip everything out, including beneficial minerals like calcium and magnesium. Cloud RO adds them back, raising the pH to around 8–9. The water tastes noticeably better than the flat, stripped taste of my mom’s standard RO.
Day 4
What was actually in our water?
Cloud’s app connects to the system’s built-in sensors, which measure water quality at three stages: as it enters, after filtration, and after remineralization. The numbers on our unfiltered tap water were… a lot.
I had been handing my kids a Brita-filtered glass and feeling like a responsible parent… I am not a catastrophist, but the pitcher was in the trash before I’d even finished reading.
Cloud RO removes contaminants like PFAS (so-called “forever chemicals”), lead, fluoride, pesticides, and microplastics – 99% of contaminants overall. It removes 15x more contaminants than the leading pitcher filter.
It’s also fully NSF certified. This is the most rigorous independent standard for water filtration systems, covering performance, materials, and safety. Not all filters can say that.
Day 9
The cooking difference I didn’t expect
I started using Cloud RO filtered water for everything – pasta, soups, and the kids’ oatmeal in the morning, – because boiling water doesn’t remove PFAS or heavy metals (who knew?!).
The 2.8-gallon tank provides consistent pressure and immediate access to purified water without relying entirely on real-time filtration, so I always have purified water when I need it. I also love that Cloud connects directly to our fridge, which has a built-in ice maker, and so our ice is now filtered too.
Day 14
Dog-approved
Our Frenchie, Biscuit, is four, and perpetually suspicious of anything new in the kitchen. I switched his water bowl to Cloud water around day ten, after reading that dogs can be sensitive to chlorine levels in water. I have no idea if that’s what made the difference, but Biscuit is very enthusiastic about his bowl these days and I’m not going to question it.
Day 18
The water bottle math
Around this point, I started noticing that we had almost completely stopped buying cases of bottled water. We’d been going through about two cases a week between the kids’ sports, and my own habit of grabbing a bottle when running out the door.
By the end of month one, we’d saved roughly 101 plastic bottles. I can’t believe it took me this long to make the switch. The money adds up faster than you’d think, and don’t even get me started on the plastic we used to waste…
It’s also worth noting that Cloud runs at roughly a 1:1 ratio. Other RO systems on the market can waste up to 10 gallons for every 1 gallon filtered!
Day 21
The app, which I thought I’d ignore and now actually use
I am not someone who downloads apps for appliances. But Cloud‘s monitoring app is genuinely useful. It tracks filter performance in real time, shows me the water quality data, and tells me when filters actually need replacing based on real usage, not just a calendar. Most filters guilt you into swapping them out every few months regardless. This one only asks when it’s actually necessary.
Day 28
Then we found out we were moving
My husband’s job situation shifted unexpectedly (in a good way), and suddenly we were looking at houses in a different part of the city. My first thought was that we’d just gotten our water situation sorted. I was not going back to the Brita era.
Turns out, the whole system uninstalls in about the same time it takes to install. At the new house, I had it running before the movers had finished unloading the living room.
Day 30
What I’d tell anyone thinking about it
One month in, the Cloud RO has quietly become as essential as the dishwasher. I don’t think about it much day to day. It just works. The water tastes noticeably better, I feel genuinely good about what my family is drinking, and we’ve almost completely stopped buying plastic bottles.
If you have kids, pets, or simply care about having truly clean water at home, I’d stop overthinking it and just get it. It’s easily one of the best purchases I’ve made in a long time. After comparing countless filtration systems, Cloud RO is the one I’d confidently keep buying and recommending again and again.
