Big Blue Water Filter Cartridges - 20" x 4.5"
For Fluoride Removal-Reduction, Arsenic reduction with KDF 55 Media
Unlike Standard Coconut or charcoal based carbon filter which cannot
filter fluoride, this filter uses a unique calcium based bone char carbon, activated alumina to reduce fluoride from your water.
Removes/Reduces Fluoride, Hydrogen Sulfide (Sulfur), and chemicals and odors! High flow size
Additional Metals Addressed By Bone Char Carbon*
*The information provided on this table is based on Additional testing results of removal efficiency for heavy metals with the use of Bone Char courtesy of Glasgow University, UK and manufacturers of Bone Char. Additional contaminants that bone char carbon is recommended for are not certified by WQA or state standards. Contaminates addressed by bone char may not be in your water.
The use of bone charcoal or bone char is reported to be an effective means for the reduction of fluoride. Bone charcoal contains a carbon structure while supporting a porous hydroxyapatite matrix (a calcium phosphate hydroxide in crystalline form which is rich in surface ions which can be readily replaced by fluoride ion). Adsorption and ion exchange are thought to be the mechanism for fluoride reduction by bone char. This filter works like regular carbon as well. A whole-house filter system treats all water traveling to any faucet or fixture in the home. It removes the chemical before it can be ingested, breathed in, or absorbed by the skin during washing or bathing. A larger carbon filter like this one provides better filtration because of the amount of carbon,and depth of the filter bed. It does not cause a water pressure drop in your home compared to solid block carbon filter installed at the point of entry. Carbon removes/reduces many volatile organic chemicals (VOC), pesticides and herbicides, as well as chlorine, benzene, trihalomethane (THM) compounds, radon, solvents and hundreds of other man-made chemicals found in tap water. Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals. Activated carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities.
Fluoride System uses premium-grade activated alumina media to effectively remove fluoride from the water throughout the entire home. This is important because fluoride exposure doesn't just occur from drinking water but also from inhalation through the lungs and absorption through your skin. Designed specifically for whole house filtration, this system supports a high service flow rate per bed size with superior particle strength to sustain regular backwashing.
We use premium activated aluminum AA400 which has a very high capacity for fluoride adsorption and was specifically designed to remove soluble fluoride from water. This porous media has a large surface-area-to-weight ratio which greatly improves metal adsorption general tap water fluoride levels (1 ppm), making it one of the most effective and longest lasting fluoride filters available on the market.
KDF Process Media are used for a variety of pretreatment, primary water treatment, and industrial treatment processes. They are generally used in place of, or in conjunction with, granular activated carbon filters, even carbon block or inline filters. KDF water filter media extend the life of granular activated carbon (GAC) while protecting the carbon bed against fouling by bacterial growth.
