One Pure mineral water is filtered using ozone to ensure it meets the highest health and safety standards. Filtering with ozone means using oxygen to clean the water.
No minerals are added in, and no minerals are taken out. Their water source is so clean and pure, there is no need to interfere with the natural structure of the mineral water.
The water is artesian, which means it bubbles out of the ground naturally, without needing heavy mechanised pumps to pull the water out.
