outstanding filter Review by Pete Bender
I have 3 parts per million of iron in my well water.This filter removes all of the iron. (Posted on 6/28/12)
Only filter that works!! Review by Binder... not B
My well water had massive amounts of iron. After we installed a huge and expensive water system the regular filters STILL were not good enough! Paper filters lasted less than a month. This one for me lasts about 3 months. This filter is amazing and I highly recomment it. (Posted on 12/20/12)
