What is a Reverse Osmosis System?

There are two kinds of Reverse Osmosis systems available: point-of-use (POU) systems and point-of-entry systems (POE). POU systems are often installed under a kitchen or bathroom sink, or inside a fridge that has a water dispenser. This system filters the tap water used for drinking, whereas a POE system will filter the water for the entire home or business, including all showers and appliances. Generally, POE systems are less common because of the higher upfront cost and long-term maintenance fees.

Reverse Osmosis Systems remove contaminants using a series of filters. The water pressure pushes the tap water through a semipermeable membrane, removing dissolved inorganic solids from the water. Most systems use a four to five step process to ensure that all contaminants have been removed and flushed down a separate drain, leaving sparkling and fresh drinking water behind.

Some impurities that can be removed are:

  • Lead
  • Detergents
  • Nitrates
  • Arsenic
  • Pesticides
  • Pharmaceuticals
  • Sulfates
  • Chlorine
  • Fluoride

Thanks to your reverse osmosis system, you can enjoy fresh and clear water for many years to come! To learn more about these filtration systems, get in touch with your local Water Depot store today.
