Point-of-entry fluoride reduction is genuinely rare, and Crystal Quest explains the chemistry properly: bone char calcium GAC carries hydroxyapatite lattice surface area alongside carbon surface area, which is what gives it affinity for fluoride, and the page is upfront that filtered pH generally rises and that the result varies with source water. The tank is automatically backwashed and rated for a million gallons at 9 to 11 GPM, which is a real household service flow rather than a point-of-use trickle. Where this gets expensive is configuration: the fiberglass 1.5 cubic foot standalone is 1,665 dollars, stainless is 2,243, and adding the SMART filter stage takes it to 3,284. No media replacement interval is published anywhere, only the gallon capacity, so the running cost cannot be estimated from the page. Nothing in the line is certified by NSF, IAPMO or WQA, which on a 1,665 dollar fluoride claim is the most material omission in the catalogue.
