The label shows the flow arrow, part number CQE-RC-04060, the operating limits and nine numbered replacement steps. Inside, the black bone char granules are sealed in, so a change is a clean swap of the whole cartridge.\u003c\/p\u003e\u003ch3\u003eHow bone char removes fluoride\u003c\/h3\u003e\u003ch4\u003eA swap inside the crystal\u003c\/h4\u003e\u003cp\u003eHydroxyapatite holds hydroxide groups in its crystal structure. Fluoride carries the same charge and is almost the same size, so it can take the hydroxide's place. The result is fluorapatite, a stable, insoluble mineral that stays locked in the media instead of returning to your water. Where fluoride is higher, some of it also precipitates with calcium from the media as calcium fluoride.\u003c\/p\u003e\u003ch4\u003eA carbon surface, too\u003c\/h4\u003e\u003cp\u003eUnlike aluminum oxide fluoride media, bone char also carries carbon: Calcium GAC has about 200 m²\/g of total surface area, about 50 m²\/g of it carbon. That carbon surface adds adsorption of some dissolved organic and colored compounds, which is why bone char has a long history in purification beyond water.\u003c\/p\u003e\u003ch4\u003eWhy pH and contact time matter\u003c\/h4\u003e\u003cp\u003eBone char takes up fluoride best in slightly acidic to neutral water, and its capacity falls as pH rises. The exchange is also gradual: the longer water stays in contact with the media, the more fluoride it can take up. That is why an inline cartridge running at its rated flow, rather than faster, gives the media the time it needs.\u003c\/p\u003e\n\u003ch3\u003eWhat it reduces\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003ePrimary target (printed on the cartridge label):\u003c\/strong\u003e fluoride, specifically inorganic fluoride in municipal water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAlso adsorbed by bone char\u003c\/strong\u003e (a capability of the media, not a separate tested rating for this cartridge):\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeavy metals such as lead, which Crystal Quest's Calcium GAC data sheet lists among bone char's strengths\u003c\/li\u003e\n\u003cli\u003eSome dissolved organic and colored compounds, through its carbon surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNot designed to treat:\u003c\/strong\u003e bacteria and viruses, nitrate, hardness, dissolved solids, or chlorine and chemical tastes as a dedicated stage.
