BIG BLUE HOUSING WATER KDF85/GAC FILTER IRON/HYDROGEN SULFIDE REDUCTION
20" x 4.5" Filter Cartridge
This system should be used where low to moderate ferrous (dissolved) iron or hydrogen sulfide contamination is known. This filter is most effective where iron and hydrogen sulfide levels are less then 5 ppm. Best removal rates are achieved where pH is between 6.5 and 8.5 and where water contains some dissolved oxygen.
The life of filter depends on the contamination levels and amount of water consumed daily. The normal filter life for typical non commercial application is about 20000 gallons.
