Why do water filters like Brita remove chlorine but not fluorine, they’re both halogens.
What about dechlorinating showerheads?

Questions On Air and Water Filter Purifiers
Saturday May 19th 2012
I don’t know if this is exactly the answer you are looking for but I will share what I know.
I don’t know about filtering out fluoride or chlorine, but if you have hard water spots… I think that comes from calcium and magnesium (meaning “hard” water). I have the same issue here and that is what my well guys said.
Options for me: filtering out at the well or filtering at sink (but would only filter out for kitchen sink) with a reverse osmosis system. We are going to filter out at the well because you don’t want the hard water going through the system as it will damage the pipes over time with all the build up. Plus the reverse osmosis system wastes a lot of water. For every gallon your get, you lose 2-4 gallons. Yikes! We are in conservation mode here and I couldn’t do that!
If you are on city water, your water should be fairly good. But contact the water quality control board and ask for results of their water testing to see what is in the water besides chlorine and fluoride (i.e. nitrates, calcium, magnesium, etc.). Good luck.
Flourine is put, by law, in the water supply for tooth decay prevention.
