H2O, Water. Agua. Few elements are as essential to healthy living as clear, clean, fresh water. In our homes, we often take fresh tap water for granted, assuming that when it’s clear, it’s clean. Unfortunately, hard minerals, pharmaceuticals, and disinfectants like chlorine and chloramine, as well as other contaminants are invisible. Simply put, water isn’t what it once was.

Our clients


We are very pleased with the product and the installation. Yes, it’s pricey. However, it exceeds our expectation and we feel we have received more than enough value for the money we spent. Mike Munns, the installation tech, was courteous, efficient, and cleaned everything up when he was done. The installation is very professional, including patching the drywall that was removed to access the pipes…We are very pleased and would highly recommend them to anyone thinking of getting water conditioning equipment.
