WHY CHOOSE Hi2O?

Water—it covers about 70% of the Earth’s surface and it makes up more than half of our body weight. This precious resource is the essence that drives health and wellness in all living things, including people.

At Hawaiian Cool Water, we believe that the water you drink should be: 1) free from contaminants and chemicals; 2) affordable and; 3) delivered in a manner that is non-damaging to our environment.

They’re plastic and their production, delivery, and “disposal” is shockingly harmful to our environment. Learn more »
