Reverse Osmosis – The Environmentally-Friendly Way to Clean Water

Reverse osmosis is the most economical method of removing 90% to 99% of all contaminants in water. Today, reverse osmosis is known as the most convenient and thorough method of filtering water. It is used by most water bottling plants and by many industries that require ultra-refined water in manufacturing. Now this advanced technology is available to homes and offices for drinking water filtration.


In reverse osmosis water filtration, two different water concentrations are forced through a micron semi-permeable membrane by water pressure, which separates the unwanted substances. The most amazing aspect of the reverse osmosis system is that the substances left behind are automatically diverted to a waste drain so they don't build up in the system, this is why the system can last so long and requires little maintenance to perform like new.
