Berkey Fluoride Filter (Set of 2)
The Berkey water filter fluoride reduction elements work by adding the ability to remove
the contaminants listed below. When threaded directly onto the
Black Berkey® purification elements the fluoride reduction element is an
effective way to take control of targeted harmful contaminants in your drinking
water. These fluoride water filters work as a post filter to the Black Berkey and is
compatible with all Berkey water filter systems.
Effectively reduces the following water contaminants
- Pre-oxidized Arsenic III and Arsenic V
- Other heavy metal ions
Filtering Fluoride From Your Drinking Water Controversy
The Berkey fluoride water filter uses a time tested method that was
developed to reduce fluoride in your drinking water. Berkey developed
this filter to address the concerns of the many who find the practice of
adding fluoride to drinking water questionable or unacceptable. Fluoride
has been deliberately added to many municipal water supplies since the
1950's. This common practice is now becoming more controversial to say
the least. New reports and studies about the harmful effects of adding
fluoride to drinking water are emerging. The health and hygiene
benefits of applying fluoride directly to the surface of teeth are a
well known and seldom disputed. The dispute begins with fluoride that
has been added to drinking water only comes in contact with the teeth
for a very short amount of time and in a very diluted form. After this
contact the fluoride is than swallowed and the human body is subject to
the well known ill effects of the fluoride compound for hours after
ingestion. Critics claim that in this age of high fluoride tooth pastes
that are correctly applied directly to the surface of the tooth, the
benefits of fluoride in the water supply are negligible and quite
possibly unnecessary. Berkey fluoride water filter allows you to make
this decision about your health for yourself by reducing the amount of
fluoride in your water by 95%.
It is recommended that each set of two Berkey PF-2™ fluoride water
filters should be replaced after 1,000 gallons (3,785 liters). Example:
If you had a Big Berkey system (2 gallon capacity) and you refilled the
system 2 times per day, you would be using 4 gallons of water per day.
Under these conditions the PF-2 fluoride water filter elements would
last 250 days (1000 gal. divided by 4 = 250) or a little over 8 months.
Actual replacement period for the PF-2 fluoride filter is dependent on
how much water you would use and the presence of other competing
contaminants in the source water. High levels of arsenic, fluoride and
certain heavy metals may negatively affect the efficiency and capacity
of the PF-2 elements.
Testing was performed with a flow rate of less than 11 liters per minute per cu.ft. of the Berkey KDF filtering medium at 20 - 30 parts per million (ppm) of the ion in the solution liquid. Results of < 1ppm of the fluoride ion in the effluent were typical for the filter media (>95% reduction). Under optimum laboratory conditions, effluent concentrations of less than 50 part per billion (ppb) were readily achieved which equates to a >99.75% reduction.
ARSENIC: Arsenic cations and arsenic oxide anions have unique properties that this Berkey filter product effectively targets.
1) Do not subject to freezing temperatures, high heat or boil the fluoride water filter elements.
2) Under normal circumstances the PF-2™ canisters reduce water filtering flow rate of most Berkey filtering systems by 15-20%.
