This one sounds like a magic spell. Activated alumina is a gritty, porous material. It acts like a sponge for fluoride.
You can find it in special countertop filters or whole-house systems. Water flows through, and the alumina grabs fluoride ions. It’s a chemical hug, but the fluoride doesn’t survive.
These filters are cheap, but they’re fussy. They work best at a specific pH level. Too acidic or too basic, and they take a nap. Check your water’s pH if you’re a perfectionist.
The Old School Hero: Distillation
Welcome to science class! Distillation boils water, collects the steam, and condenses it back into liquid. It’s like making rain in your kitchen.
Fluoride has a higher boiling point than water. So when the water turns to steam, fluoride stays behind in the boiling chamber. You pour out pure water.
Downside? It’s slow and uses a lot of electricity. Also, distilled water tastes flat. Add a pinch of sea salt to bring back the zing. Your taste buds will thank you.
