Water classification
Purified water
Derived from a municipal source and filtered through reverse osmosis, with a minimum amount of added minerals.
Spring water
The most authentic form of water, sourced from natural springs.
Mineral water
Comes from natural springs and must have a mineral content, also known TDS, of at least 250 parts per million (ppm).
Distilled water
Water that has had many of its impurities removed through distillation. Distillation involves boiling the water and then condensing the steam into a clean container. Long-term consumption of distilled or demineralized water containing low TDS levels is not recommended and can be linked to increased diuresis, body water volume, serum sodium concentrations, decreased serum potassium concentration and increased elimination of sodium, potassium, chloride, calcium and magnesium ions from the body. Simply put, drinking distilled water for an extended period of time can jeopardize your health.
