Review on Upgrade Reverse Osmosis Re Mineralization Water by Heather Gorman

I like to place the remineralization cartridge after the reverse osmosis membrane and before the storage tank. Truly pure water likes to clean and balance itself and can pull rubber and plastic out of the tank. If you remineralize it first, it will be less prone to it. This cartridge also makes the water taste better for most people. I like to use the final GAC filter (Granulated Activated Charcoal) after this remineralizer as the final "polish" step before drinking. This cartridge comes with extra fittings and mounting brackets as a bonus. That's a good value. 5 Stars.
