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 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.

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.
