The RFFE10-BB will take care of the permanganate and some of the iron, depending on how much there is in the water. However, it is our professional recommendation that you would need a water softening system in order to fully treat your water. If you have any further questions regarding this please feel free to contact us toll free at 1-877-432-4117. I have also included a link to the RFFE10-BB on our website:
