Reverse Osmosis Water Filter Systems

Reverse Osmosis Water Filter

What is a Reverse Osmosis?

Source: WQA

A water treatment process that removes undesirable materials from water by using pressure to force the water molecules through a semipermeable membrane. This process is called "reverse" osmosis because the pressure forces the water to flow in the reverse direction (from the concentrated solution to the dilute solution) to the flow direction (from the dilute to the concentrated) in the process of natural osmosis. Visit our 'How Does Reverse Osmosis Work' guide to learn more and see the steps in a reverse osmosis system.

RO systems are also used to purify water before sterilizing it with a Ultraviolet Systems or attached to a Bottleless Water Cooler.

What does a Reverse Osmosis Water Filter Remove?

Reverse osmosis water filtration systems can remove 90% of total dissolved solids (TDS) from water and can provide the purest water available for your home. Reverse osmosis water filters remove a wide range of contaminants and minerals from your drinking water, including sand, chlorine, fluoride, cryptosporidium, and hexavalent chromium.
