Prefer to reduce it? Reverse osmosis is the technology to look at.
Jugs, tap filters and standard carbon cartridges aren't designed to reduce fluoride. Crystal uses an RO membrane, the technology used for fluoride reduction.
Testing for fluoride
Can you test my water for fluoride?
We can point you to an accredited lab and talk you through the result.
What does a TDS reading show?
TDS shows dissolved solids. It isn't a fluoride or PFAS test.
