Not sure about rain water but do not boil tap water as that will increase the level of fluoride in your water, not remove it at all, which contradicts the idea of "removing fluoride from water by boiling”
+1 for ZeroWater. Cant believe I had to scroll this far to see someone mention it. They claim it removes fluoride and the tester they provide seems to prove it.
