If our customers experience any performance issues with our cutting edge water ionizer systems, then we will fix or replace the unit (within a week in most cases). Any damaged unit will be fixed, or replaced with a comparable unit at no cost to you (excluding shipping). The only thing not covered under our warranty is accidental breakage that could be caused by dropping one of our units or damage caused from something of a similar nature. Feel free to use our units in any type of water, and produce as much water as you wish. Our advanced cleaning system, filtration, and power methods are the toughest and most advanced in the industry.
