Through years of research, Mistbox has developed a custom water treatment system to ensure the fine mist won't damage your AC unit. The patent pending process kills bacteria on contact and treats metal surfaces to make algae or mold growth an impossibility.  Also, dissolved solids (hardness) in the water is neutralized so hardness cannot tightly adhere to the condenser fins. The Mistbox filters have been designed to work with municipal water anywhere in the continental US. Though our method works with many international water supplies, please consult Mistbox before using outside the US.
