What On Earth is Reverse Osmosis?

Reverse Osmosis (RO) is a water filtration process that works by forcing water through a membrane that separates ions and removes 99.99% of water contaminants, including fluoride and chlorine. Reverse Osmosis is considered the KING of water filtration with the ability to remove the most impurities out of all the water filtration systems available on the market today. 

A reverse osmosis system is most commonly installed under the sink. However, many My Water Filter systems provide benchtop reverse osmosis options for people who rent as well.
