What makes a reverse osmosis system unique is the RO membrane, which filters water by using the water pressure to force it through the membrane so it can remove 99.9% of the contaminants from the water flow.
These drinking water systems are becoming popular because of the growing level of contamination in our water. Our every day drinking water sources are becoming more and more contaminated with pesticides, chemicals, and other potential health risks.
An undersink reverse osmosis drinking water system is needed because of water processing, adding chlorination, chlorine, fluoride, chloramines, and other chemicals to our water supply to keep it clean from parasites and bacteria.
Reverse osmosis drinking water systems use an activated granular carbon filter for chlorine and other chemicals. They can also use additional types of filters to remove the more chemicals and particles that a carbon filter doesn't remove.
