Reverse Osmosis is a water treatment method that uses artificial pressure to push water through a semipermeable membrane to remove contaminants. It is the most sophisticated and effective filtration technology available for household use.

Ro water filtration systems reduce up to 99% of dissolved solids and most organic chemicals*, as well as some heavy metals like lead and mercury. They also reduce bacteria, cysts, and other microorganisms.

A properly designed and maintained RO system produces drinking water of the same quality as bottled water. It can significantly improve the taste and odor of your water, as well as provide a number of health benefits.

How to Choose the Right Reverse Osmosis Drinking Water Filter

The main disadvantage of ro water filtration is the amount of waste water generated by the process. Depending on the model you choose, it may produce between 3 and 6 gallons of waste water for every gallon of pure water produced. This has led to a negative reputation for reverse osmosis, although recent improvements in membrane technology have helped reduce the amount of wasted water.

Reverse osmosis can reduce fluoride, which is added to most municipal drinking water supplies to prevent tooth decay. It can also reduce the concentration of other chemicals, such as volatile organic compounds (VOCs), pesticides, and industrial cleaners.

The process of ro water filtration can remove valuable minerals from the water, but many systems include a re-mineralizer to add back healthy minerals to the water. RO water is generally considered healthy and safe to drink, but it is important to test your water before installing a filter to ensure that you are removing the right substances. A professional water test conducted by your local Culligan dealer can help identify problem water issues and recommend the best solution.
