    My well water has extremely high naturally occurring fluoride (6.5 mg/L). That is about 4 times higher than the recommended level for consumption. We run our water through a reverse osmosis system. I have a TDS meter and I know the TDS is reduced from 370 mg/L to about 40 gm/L. Is it safe to assume that the fluoride level will have dropped below 2.0 mg/L? Do RO systems preferentially remove one ion over another? The simple answer would be to get my water tested again - but it's not cheap. If anyone knows of a good fluoride test kit, perhaps that might be the way. The last time I had it tested, it went to a lab.

    Thank you.

    Many RO's used to be good, until the manufacturing was sent overseas. Many of the HT Ro's had built in monitors, but a simple TDS tester should suffice. You can interpolate the performance for fluoride rejection based on general tds rejection. This is obviously not 100% accurate but it will give you a good estimate.
