yes, there is a filter for fluoride, from a company named vitasalus. I have one of their filters is how I know this. I do not have their fluoride eliminating filter and this is a whole house filter that is not in any way cheap. The company is out of Michigan.

I am fortunate to have only tank water - only the chemicals that fall from the sky in that :-(( Jane I don't think there is a filter system on the market that will remove Fluoride. I spoke with reps of the Seagull home water purification systems {which of course they say is the best money can buy} but nowhere in their information material does it state theirs will remove Fluoride, everything else seemingly <g> but nowhere does it state Fluoride removal. My understanding is RO is the only way to remove it, and that I am led to believe is fairly cost prohibitive for the home.
