I was expecting great "tasting" water, I was buying Fiji, but wow! I live in a MUD district that has two wells, yet treats the water with all the same nasties as the cities. For my little granddaughter, especially, it was time for all of us to live fluoride free, not too mention radiation, pharmaceuticals and waste chemicals! This water filter system had an unexpected benefit with the few years old all copper piping, and standard fixtures: shower heads became unclogged, toilet bowl water flushing alone seem to clean the stains! In general, good water naturally cleans our bodies and our stuff! Thank you, Igor, with your help and patience! Highly, highly, recommend !!!
