Fluoride
From information sources that relate to activated charcoal, we know that fluoride
is not trapped by any charcoal filter.
From
the summary of Health Canada’s subcommittee on Guidelines for Canadian
Drinking Water Quality, we have a 1.5 mg/l acceptable level for fluoride.
Our test report from Sucofindo Laboratory in Indonesia, shows a test
result of below 0.02 mg/l using 1995 Standard Method of Testing #4500F-D.
The Indonesian acceptable level is also 1.5 mg/l
Fluoride
is an inorganic chemical. The MTF filter Of the Regency unit traps organic
chemicals. In the Encyclopedia Britannica, fluoride is listed among
the anions while sodium, potassium, magnesium and calcium are listed
as cations. After water has passed through the 6 stage filter, it enters
the Electrolytic Cell which contains 2 chambers. These chambers are
separated by layers of membranes with holes so small that water molecules
cannot go through, but large enough for the ionized inorganic chemicals
and minerals to do so. This is where the fluoride is partially removed
from the drinking water and flushed out with the acidic water.
So
now we know the actual ionization process will remove a good percentage of Fluoride and my guess is from 50% to 75% maybe higher but there are variables to consider.
Since Fluoride is of a polarity which will pull it into the acidic flow
of the water, it will depend on the power adjustment and the flow rate.
Of
course there are the 'acceptable' levels but most health conscious people
are not satisfied with that. Therefore, we offer an optional pre filter for those wanting the 97%+ removal. |
