When my husband and I finally bought our first home last year, we knew the kitchen would be the heart of it all. After years of living in cramped apartments with questionable tap water, upgrading our kitchen wasn’t just about new cabinets and fancy lighting — it was about feeling good about what we were cooking with and, more importantly, what we were drinking every single day.
I still remember our first morning in the house. Boxes were stacked to the ceiling, the kids were running wild, and I poured myself a glass of water straight from the tap. One sip, and I knew we had a problem — the water tasted metallic, and the smell was even worse. Bottled water was not an option forever. Between the kids’ water bottles for school, coffee in the mornings, cooking pasta, and making soup, we needed clean water — and a lot of it.
That’s when I started researching an undersink reverse osmosis system. After comparing so many options online, reading endless reviews, and asking friends, we landed on the SimPure Q3-600 under sink tankless RO system. It checked all the boxes we cared about: high capacity, tankless design (our under-sink cabinet was already stuffed with cleaning supplies), and easy DIY installation. Plus, the fact that it was tested by SGS to meet NSF standards gave us peace of mind.
Easy to Install, Even for Us
Neither of us is particularly handy — I can put together IKEA shelves, but that’s about it. The thought of installing a water filtration system seemed intimidating at first. But the SimPure Q3-600 made it surprisingly doable. The box came with everything we needed, and the instructions were clear enough that my husband could handle it on a Sunday afternoon while I kept the kids out of the kitchen.
What I love most about this system is that it’s tankless. In our old apartment, my parents had a huge old RO system that came with a bulky storage tank under the sink. It was always in the way, took up so much space, and made replacing filters a pain. With this one, it’s compact — it takes up barely half the cabinet, leaving us room for dish soap and the recycling bin.
First Glass, Fresh Glass
One thing I didn’t realize about old reverse osmosis systems is that the first glass of water you draw can sometimes taste off because of residual water in the pipes or tank. The SimPure Q3-600 under sink tankless RO system solved that with its “Fresh Water Technology.” Every glass tastes clean and crisp. No more dumping the first cup down the drain. The kids can just grab their water bottles and go.
It’s also fast — and I mean really fast. It can fill an 8-ounce glass in about 8 seconds. With two kids constantly asking for water, plus cooking and coffee brewing, the high flow rate really makes a difference. And it has a 2:1 pure to drain ratio, which means it doesn’t waste as much water as other RO systems do. That was important to us, both for the water bill and the environment.
A Small Upgrade That Made a Big Difference
It’s funny how something you don’t think about, like water, can change how you feel about your home. Before, I was always buying bottled water, worrying about whether the kids’ water tasted funny, or if it was safe to use tap water for soups and baby formula. Now, the undersink reverse osmosis setup gives us peace of mind. I use it for everything — washing veggies, making ice cubes, cooking rice — you name it.
Our coffee even tastes better. My husband noticed it first: “Did you change the coffee beans?” he asked one morning. Nope. Same beans — just better water.
Another bonus? The SimPure Q3-600 connects to our fridge’s ice maker, too. We never had that option before, and I can’t tell you how nice it is to have clear, clean ice for cold drinks in the summer. No more cloudy cubes or weird taste.
The Little Things Add Up
I also appreciate the filter life reminder. With other systems, I always worried about forgetting to change the filter. This one gives you a clear reminder and the filter swap is easy — I can do it myself in a few seconds. Plus, the filters last longer than I expected, which saves money over time.
When we have friends over, they almost always comment on how good the water tastes. It’s one of those tiny details that makes our new house feel like a real home.
Final Thoughts
If you’re a first-time homeowner or just tired of dealing with sketchy tap water and stacks of plastic bottles, I can’t recommend the SimPure Q3-600 under sink tankless RO system enough. It’s one of those upgrades that you don’t fully appreciate until you’ve lived with it for a while — and then you wonder how you ever managed without it.
Sometimes, the best home improvements aren’t the flashy ones people see when they walk in. Sometimes, it’s what they taste when you offer them a glass of water.
