The Pentek RFFE20-BB replacement radial flow Iron reduction filter effectively reduces up to 3 PPM of dissolved iron from water. The RFFE20BB improves the metallic taste caused by iron and will reduce the orange & brown staining found in your sink, toilet, tub, and other plumbing fixtures. Another great feature of this RFFE20-BB filter is that it doesn’t add any harmful chemicals to your water so you can use it for drinking water applications as well. This iron water filter should be installed on the main cold water line after the pressure tank or water meter.
