4.5" x 20" Whole House Big Blue Refillable Well Water Filter Cartridge - GAC Catalytic Carbon/Birm + KDF 85: Removes Iron, Manganese, Hydrogen Sulfide - Rotten Egg Smell

This mix of coconut shell Activated Catalytic Carbon, Birm and KDF 85 is most often used for iron, manganese and hydrogen sulfide reduction, which works well for removing the "rotten egg smell" from the water. This filter fits any standard housing made for 4.5" x 20" cartridges. Save money with this refillable inline filter. Our filter cartridges have superior taste and odor removal capabilities. There are two types of media in these types of filters: the KDF media in this cartridge specializes in the removal of iron and hydrogen sulfide and the activated carbon is effective against chlorine, odor and taste. Kdf process media are high-purity copper-zinc granules that reduce contaminants in water using oxidation/reduction (redox) reaction. Kdf 85 process medium is an effective iron (ferrous) and hydrogen sulfide (H2s) removal agent that may be used alone or to protect existing water filtration/purification technologies in PoE treatment of groundwater supplies. Effectively reduce/remove chlorine, iron, hydrogen sulfide, heavy metals in potable water without the use of chemicals. This is an excellent choice if you are looking for a filter that will remove a wide range of contaminants.
