Purification Process

Providing you the Best Water

Our Hawaiian Source
The Hawaiian Islands are one of the world’s most isolated landmasses. Their volcanic origin, abundant rainfall and clean air provide ideal, natural conditions for pure drinking water.

Our water begins as abundant rainfall within an environmentally-pristine, virgin rain forest. This exceptional water naturally filters through thousands of feet of lava rock slowly trickling on a 25 year journey into our protected aquifer which becomes our source.

Our Ultra-Purification Process
We further enhance our pure source water through a state-of-the-art 8-Step Filtration Process to achieve our “Ultra-Pure” Water. The U.S. Pharmacopeia uses “Total Dissolved Solids” (TDS) as a Key Measure of Water Purity with the lower the level the better.

“Ultra-Pure” Menehune Water has fewer than 5 parts per million TDS. That’s less than 1/2 the USP Standard for Purified Water of 10 parts per million! Our “Ultra-Pure” level enables maximum absorption by your body.
