fluoridated, so although he knew the PurifiCups filter reduced
the amount of fluoride in water, he wanted to learn more about it
and see if his product could be improved to remove even more.
In an email
to me he stated:
of our manufacturing partners in Taiwan and suppliers from Japan
do not use any fluoride in their countries, and due to the different
values of each citys application in concentrations varies..
we had to do the (fluoride) test in the U.S. We have found the
most common fluoride level in U.S. cities to be roughly 0.40-0.86
ppm (parts per million). So we did our testing with tap water
from the city of Plano, Texas. The City states the fluoride level
to be between 0.46ppm -0.66ppm range.

from Hanna Instruments and second, testing both the City of Planos
water for fluoride and then a sample that had been filtered by a
