No, the shower filter won't remove fluoride and I also have a bath ball (not the same as yours) again, that does not remove fluoride, only chlorine.
I'm now thinking I need to get a whole system for the house, some sort of reverse osmosis sytem - one that I can only afford if I sell the house! So that is out of question :-)
Or ... I can program some Orgone to eliminate the fluoride. Hmmmmmm!
Each question I ask seems to dig my hole a little bit deeper. I better bury my head in the sand later or I won't be able to sleep!
