The Reticulated KDF-55 Filtration Media Stage is a remarkable REDOX media (oxidation/reduction), representing a new and unique natural process of electrochemical oxidation/reduction and adsorption action. KDF-55 targets the dissolved inorganic contaminants (up to 98% of soluble cation heavy metals including mercury, lead, chromium, cadmium, etc.).
KDF-55 also prevents corrosion and eliminates scale by transforming hardness minerals into crystalline structures that do not adhere to plumbing & appliances (learn more in the What is Salt Free Softening? section below).
SNRF Ion Exchange Catalytic Coconut Shell Carbon is an adsorbent media that target the volatile organic compounds (chlorine, THMs, disinfection by products, herbicides, pesticides, etc). This carbon is supercharged with an internal modification for ion exchange properties for soluble lead adsorption (Ion Exchange Capacity is 130mg/g). The heavy metal reduction capability is redundant given that reticulated KDF-55 is also incorporated in to the system design, guaranteeing 99% removal of soluble lead (even at high flow rates).

The Calcium Based Carbon (BRIMAC), also known as Bone Char, has a unique porous matrix of ions created by heating a calcium based raw material in an oxygen rich vessel at 1,292 °F. The result is a unique type of Calcium Based Activated Carbon with properties that a very different the more common Coconut Shell Activated Carbon. While coconut shell carbon is great for organic contaminants, it is not effective for inorganic contaminants. However, Calcium Based Carbon is selective for filtering inorganic contaminants.
Fluoride filtration is the most common application for Calcium Based Carbon, it is also used in applications for radionuclides reduction including radium, uranium & arsenic present at levels below the MCL.
By nature fluoride is one of the more slowly adsorbed contaminants. High quality fluoride media & a large quantity of those medias is required for whole house reduction of this contaminant. While 90+% removal of fluoride is not generally feasible for Whole House Water Filtration Applications, this stage of the dual tank system will reduce exposure to fluoride significantly.
Exposure to fluoride is primarily a concern with ingestion. Fluoride is not readily adsorbed through the skin and does not vaporize when heated like chlorine & disinfection by products. Since that is the case, if Fluoride Filtration is the sole reason for selecting this upgraded system, we highly recommend you consider installing CuZn’s Wide Spectrum Model Whole House System & a Kitchen Water Filter. Going this route is more economical & offers the best value for your fluoride concerns.
Zeolite Filtration Media – is a fascinating material with both adsorbent & ion exchange properties. The most prominent application for Zeolite is ammonia removal. Zeolite compliments activated carbon’s adsorption of volatile organic compounds, as Zeolite tends to offer greater efficacy with the removal certain organics that activated carbon is less efficient adsorbing. It also has shown promise for the removal of various radionuclides with its unique ion exchange properties.
Rx Filtration Media – is a mesoporous organosilica media that possesses a flexible and hydrophobic pore structure. Rx media is able to remove nearly all forms of pharmecutical contamination found in potable water supplies (testing shows 99% removal of antidepressants, antibiotics, birth controls & 75% removal anti-inflammatories, antihistamines). Rx media can also be used for the extraction of organic species, including hydrocarbons, all forms of oil, chlorinated solvents, esters & glycols.
