For Your Health

Reverse Osmosis System

If you replace the water your body needs by drinking tap water, your body is forced to act as a filter—straining out contaminants which can lead to health problems, including cancer, kidney damage, miscarriage, and gastrointestinal upsets. By contrast, a reverse osmosis water filter can distill your tap water to 99.9% pure!
