What's the difference between RO and DI water

People looking for the right Water Purification System often ask me, "Whats the difference between RO and DI water purification technologies?" Here's the short answer: RO and DI filters use different physical reactions to clean water. Reverse Osmosis (RO) is often used to partially clean-up tap water to make it roughly 90% to 99% pure.
