How To Reduce Arsenic In Drinking Water
Arsenic is a carcinogen that can be found in drinking water. Reverse osmosis can remove up to 99% of the dissolved salts, particles, organics, and colloids from the feed water. Cross filtration helps to avoid the buildup of contaminants by allowing the water to wash away the contaminant buildup while allowing enough turbulence to keep the membrane surface clean. RO systems also employ cross filtration instead of standard filtration, where the filter media trap the contaminants.
All you have to do is swap out the filters and membranes according to your system’s manual. Better yet, you only need to replace most of the filters every six to 12 months, and replace the RO membrane every two to three years, depending on the water quality in your area and the volume of water supplied by your system.
