Artesian Water: Water from a well that taps a confined aquifer (a water-bearing underground layer of rock or sand) in which the water level stands at some height above the top of the aquifer. Rich in minerals. Great for use with Hydrogen Water Sticks.

Spring Water: Water derived from an underground formation from which water flows naturally to the surface of the earth. Generally rich in minerals. Great for use with Hydrogen Water Sticks.

Purified Water: Water that has been produced by distillation, deionization, reverse osmosis, or other suitable processes. Lacking important minerals. Process often necessary to clean local tap water. Strongly suggest adding ionized minerals back into water for use with Hydrogen Water Stick and normal everyday usage.

Distilled Water: Water that has been vaporized into steam, then cooled to re-condense it back into water. The water’s minerals are left behind, leaving only pure tasting steam-distilled water. Lacking important minerals. Process often necessary to clean local tap water. Strongly suggest adding ionized minerals back into water for use with Hydrogen Water Stick and normal everyday usage.

Tap Water: Varies from region to town to town. Be sure to filter Chlorine and Fluoride with good filters. If you don't know what Chlorine and Fluoride can do to you, try Googling the words; tones of reading material on the internet.
