How does a reverse osmosis water filter work?

Reverse osmosis water filters use tremendous pressure to force water through a membrane which blocks harmful contaminants like lead, mercury,fluoride, arsenic, chlorine, pesticides, herbicides and other chemicals from getting into your drinking water. The result is clean, clear water that tastes great!
