Very effective at removing H2S smell from Well Water (Depends on Local water quality, chemistry, and conditions which vary dramatically from location to location)Replacement Media: Catalytic Carbon + Birm - https://www.ebay.com/itm/274538750565KDF 85 (1-2 lbs) - https://www.ebay.com/itm/283441804000 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 10" cartridges. Save money with this refillable 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.We make no specific claims as to the effectiveness or health benefits of any products we sell. Local water quality, chemistry, and conditions varyBIG BLUE 4.5 X 10" Filter/Cartridge BIG BLUE Filter to Remove Iron/Sulfur/Rotten Egg Smell Cartridge, KDF85 10" x 4.5" for Sulfur, Iron, Bacteria, Rotten Egg Smell THIS FILTER CARTRIDGE WILL FIT A BIG BLUE HOUSING 10" SPECIAL MIX OF BIRM, CATALYTIC CARBON , AND KDF85 KDF 85 Medium Removes or reduces iron and hydrogen sulfide from municipal or other water supplies. Also controls scale, bacteria and algae. iron / hydrogen sulfide reduction filter contains a combination of KDF85 media and coconut shell activated carbon. The KDF85 effectively reduces dissolved iron and hydrogen sulfide odor over a wider pH range than possible with standard oxidation filters such as manganese greensand, thereby protecting your plumbing system including toilets, bath tubs and showers, and appliances such as clothes washers and dishwashers, from unsightly staining and odor. The activated carbon removes organic contaminants to substantially improving water clarity, taste, and odor. It does NOT add any harmful chemicals to the water, making it completely safe for drinking water applications. Advantages: fraction of the cost of competitive iron removal systems easy to replace cartridge - no media regeneration necessary! NO backwashing required! effective over a wide pH range of 6.5 to 8.5 also removes manganese and hydrogen sulfide (rotten egg smell) does not add harmful bi-products to your drinking water prevents staining of laundry and plumbing system including you shower and tub will not harm your septic system filter features built-in granular activated carbon post-filter for the removal of a wide range of organic contaminants and better tasting water. filter media inhibits bacteria growth (bacteriostatic) Application: This system should be employed where low to moderate ferrous (dissolved) iron or hydrogen sulfide contamination is known or expected (hydrogen sulfide produces a distinct rotten egg / sulfur odor). This filter is most effective where iron and hydrogen sulfide levels are less than 5 ppm. Best contaminant removal rates are achieved where the pH is between 6.5 and 8.5 and where the water contains some dissolved oxygen. This filter will also remove ferric iron through mechanical filtration, although a sediment filter may be a more cost effective choice. If your water's pH level is 7.0 or higher, you should consider our PH5 iron / hydrogen sulfide reduction filter which uses a different filter media - the replacement cartridges are significantly cheaper. The life of the filter cartridge depends on the contamination level (iron, manganese and hydrogen sulfide levels) and amount of water consumed on a daily basis. The expected filter life for a typical residential application is about 20,000 gallons (75,500 L). For best results and longest filter-life, a sediment pre-filter is recommended. What types of contaminants are you dealing with? ProblemLikely Cause rusty red or brown staining of fixtures or laundry and/or your water has a metallic tasteexcess iron black staining of fixtures or laundryexcess manganese rotten egg smell from waterHydrogen sulfide (H2S) How it Works: KDF85 media acts as a catalyst to change soluble iron (ferrous) cations into insoluble ferric hydroxide which becomes trapped in the filter. The hydrogen sulfide is converted into an insoluble sulfide precipitate which is then similarly trapped and filtered. Ferric iron is removed by mechanical filtration.
