Hi, Russ and other forum members:

Again, my apologies for not replying sooner, I am still trying to figure out how to set up email notification to those threads, which I initiated.
For now it is "blind checking" every few days, so that people would not think I "walk away" from my posts.

I am not sure if calcium acetate is a proper chemical name for this stuff, but I get it by adding acetic acid CH 3 COOH(vinegar) to eggshells (CaC03)

As for commercial filters, here is what I got on my search for "Fluoride Removal" (paid listings)
www.equinox-products.com Top Whole House Fluoride Removal Filter System. Free Ship. Now $495.

Fluoride Removal Filters
www.PureWaterEssentials.com Remove fluoride from tap water! Undersink, counter, or whole house

Again, beware of false claims that "reverse osmosis" removes fluorides.
Also, a "whole house" may mean that the filter capacity is also wasted to filter water for toilets and laundry.

"Reverse osmosis" cannot be "whole house" because it is very slow. It has an accumulation tank, which is being gradully filled "while you sleep".
One acquaintance had such a system, but he never assayed the water.
The tank is closed, you cannot open it and wash it. There is an inlet opening and an outlet.
If you use the same tank for 10 years (changing filters as required), would smth grow in it?

According to books it is the "Type 3", the lowest laboratory grade water, imho not worth the money, except for removal of bacteria and viruses.

Best regards
Oleg
