I’ve been using RO systems for years, and this is by far the best post-filter I’ve tried. After installing this 4-in-1 filter, the taste of my water dramatically improved—it’s smoother, less acidic, and has a refreshing mineral feel. I love knowing it adds back calcium and other essential minerals lost during RO filtration. The added tourmaline and ORP features are a real bonus. I feel more energized, and my digestion seems better too. It was easy to install and fit perfectly as the final stage. Highly recommend for anyone wanting truly healthy, alkaline drinking water from their RO system!

I’m happy with the water quality and the health benefits this filter offers—my water tastes noticeably better and my TDS readings went up slightly, which is what I wanted. My only minor complaint is that it slightly reduced the water flow at the faucet, possibly due to the dense media. Still, the performance makes up for it. I feel better using this compared to a plain post-carbon filter. Would buy again!

Excellent Upgrade for My RO System. I was looking for a way to remineralize and alkalize my RO water, and this filter did the trick. After a few days, I noticed a clear difference in taste—crisper and more natural. I tested the pH, and it consistently hits around 9. The filter also helped reduce that “flat” RO taste. I appreciate the mix of tourmaline, ORP, and calcite—definitely a step up from standard carbon-only post-filters. It’s reassuring to know it adds essential minerals too. Great value and fast shipping!
