Review on Waterdrop WD RF10 MZ Replacement Remineralization Filtration by Bill Howard

Fits my Waterdrop 15UA under sink water filter system. I softened soft water with KCl. This removes almost everything from the water. That might sound like good, clean drinking water, and for the most part it is. However, it made for bad coffee! The lack of minerals resulted in poor and inconsistent coffee extraction. So, time to try remineralization! It does the job! Instantly increased GH from 0 to a nice 3.5. To be honest I don't notice a huge difference when I drink it, but I definitely notice a difference in my coffee!
