A "pH water filter" is an acid neutralizer: a whole-house tank of calcite, which is crushed limestone, plumbed in where the water enters the house, that raises low pH well water to about 7. Google shows four things under that name, a pitcher, an under-sink cartridge, the whole-house tank and a chemical pump, and only the tank treats every pipe in the house. I go through which one you are looking at, why the limestone is the natural fix, how to find out whether your pH needs one, where the tank goes, and what changes after it is in.
