This is the gold standard for fluoride removal. Reverse osmosis systems force water through a special membrane that blocks fluoride (and tons of other contaminants) like a bouncer at an exclusive club. They’re often installed under the sink, and they can remove up to 95% of fluoride.
Yes, they cost a bit upfront, but think of it as an investment in your personal water bar. You’ll be sipping like a connoisseur!
