Tony, is taking bath or shower in fluoride water really that dangerous? I mean I usually take cold/hot shower alternately
so how much of fluoride I'd absorb during like 10 minutes? isn't that amount negligible?
I'd invest in house level fluoride filter but I'm not sure and convinced if this is really needed. For drinking water I use distilled and spring water anyway.
Is there any DIY way to measure level of fluoride in water?
