One Heart Water is distilled water sourced from public Canadian water.

The process of distillation involves heating water to the boiling point so that the water becomes steam and rises to separate itself from debris and other impurities. The steam is then condensed back into pure liquid form, while the impurities are flushed away. The treatment process also includes pre and post filtration and ozone disinfection, which results in water 99% pure and free of contaminants and impurities.
