Well that was two months wasted. I should have known to actually do some research instead of believing all the claims that distillation is effective.Distillation will remove as much as 60% to as little as 20% of the fluoride depending on starting concentrations.
The effect of water purification systems on fluoride content of drinking water Prabhakar A R, Raju O S, Kurthukoti A J, Vishwas T D - J Indian Soc Pedod Prev Dent
Unprocessed borewell and tap water samples showed mean fluoride values of 3.51 ± 0.02 and 0.26 ± 0.02, respectively [Table - 1]. In the borewell group, processed water samples showed a reduction of about 72.2% in the fluoride content by reverse osmosis system, 55.6% by distillation, 28.9% by activated carbon, 63.9% by Reviva® , and only 2.4% by candle filter; these differences were statistically highly significant ( P < 0.001). Processed tap water samples showed a reduction in the fluoride content of about 37.9% by reverse osmosis system, 17.5% by distillation, 14.6% by activated carbon, and 21.4% by Reviva® , which was statistically highly significant ( P < 0.001); by candle filter the reduction was only 1.5%, which was statistically significant ( P < 0.05).
