What is the deal with 20% more oxygen in the water and why is that important?

The reason we have chlorine in our city water is to kill the bulk of the bacteria that accumulates and grows in our water as it travels through the water pipes. Most water purification systems use a carbon filter because carbon removes chlorine taste and smell. It also removes the dead bacteria. This carbon filter clogs up over time and it needs to be replaced. Once the water passes through a typical carbon filter, it becomes infected with more bacteria from the bio layer in the dental tubing farther down the line. If you have excess oxygen (i.e. 20%) in the water, most harmful bacteria would not survive! Bacteria does not live in excess oxygen. The NanoPURE™ system is the only water system that has excess oxygen in the water after it passes through the media filter.
