Review on 🚗 Optimized Replacement Cartridge for Everpure EV9270 74 H 300 HSD by Jerry Frey

I installed this in my kitchen sink water line. I heard Everpure is one of the best filters so I wanted to see how well it filters my water. I have filtered well water for the whole house. After installation, I ran the filter for about ten minutes to remove anything that might have been in the new filter, and did the same for a kitchen sink that didn't have filter media installed. I used a calibrated HM TDS digital pen, also purchased from Revain, and ran five water tests. Water straight from the tap averaged 780 ppm, while Everpure filtered water averaged 890 ppm. 110 ppm MORE than unfiltered water. I wanted to return the filter and the Revain guarantee only allows a partial refund and doesn't cover shipping so I'M REALLY DISAPPOINTED!
