Re: Chlorine or Fluoride?

Thanks for this timely topic. I have been in a dilemma. Have been searching for a filtration system that can take out fluoride. My brother told me that Reverse Osmosis is the way. The others are Activated Alumina Defluoridation Filter (which I can't seem to find in any of the filters in my country) and Distillation (which is not possible for me).

Based on this CDC document (http://www.cdc.gov/healthywater/drinking/travel/household_water_treatment.html)

"A reverse osmosis filter has a pore size of approximately 0.0001 micron.

Reverse Osmosis Systems will remove common chemical contaminants (metal ions, aqueous salts), including sodium, chloride, copper, chromium, and lead; may reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous."

My limited chemistry knowledge believe that since fluoride is high up in the period table, it's pore size must be very small. Any other filtration system that doesn't filter 0.0001 micron would not work on fluoride. (I would LOVE to be wrong about it, so please correct me if I am wrong!)... I've also looked through expensive filtration systems that costs thousands of dollars with 5,6,9 cartridges or plates or whatever technology (3/4/5 levels of alkaline/acidic water options) but none of them can confidently tell me that their system gets rid of fluoride.

However, here's the kicker. There are also huge disadvantages to RO water. I read that RO water will result in mineral loss from your body if you drink only RO water.

I wonder if anyone have any good ideas? Tweet
