Fluoride in Drinking Water: The Basics
Why fluoride is added to some municipal water, at what level, and how it relates to shower filtration.
Read →How a shower filter works
Tap water first passes a sediment stage that catches particulates, then KDF-55 redox media for metals and free chlorine, activated carbon for odour and VOC, and finally vitamin C for chloramine — so the water reaching your shower is filtered, not softened.
We explain each stage in plain language across the Learn library — no marketing shortcuts.
