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.

I am using a Big Blue Dual 20 filter. I was getting toilet and tub rust stains with a sediment and carbon filters. I replaced the sediment filter with this Iron reduction filter. Immediately the metallic smell in the water disappeared and it tasted better. After two weeks now, I have not seen any trace of the rust stains. If the filter last for a few months, and only time will tell, then this is definately an outstanding product.

I have very hard water with Iron and methane gas. I use a sanitizer water softener that also removes Iron. After softening, the water still had .5ppm of Iron a strong metallic smell, and left black and brown stains in the toilet, tub and shower. I tried several types of Pentek filters and worked my way up to the RFFE20-BB - Radial Flow Iron Reduction Filter. This is the best filter I have ever used. The water is softer and there is no trace of a metallic smell. The fixtures have been cleaned and after 3 weeks of use no stains!
