Anyone ever use the Zero water filtration system? I use it for my drinking water it removes all TDS down to zero hence the name... Not 100 % sure this is the best thing? I also use a Pur water filter and the water that comes out of my window AC along with rain water. All these water sources at my location start between 7.0-8.0 ... SO I am just trying to figure out my best "clean" "raw" water source, any and all input would be helpful I am just trying to learn a better way... Thanks
