What is Reverse Osmosis?

Reverse Osmosis (RO) water treatment is a process where pressurized water passes through a semi-permeable membrane to remove 90-99.99% of dissolved salts, metals, and other contaminants~. The membrane consists of tiny pores that prevent anything larger than a water molecule from passing through and filters out contaminants such as chemicals, unwanted ions, and sediment particles. What you’re left with is cleaner water that your family can enjoy.
