We cannot ship to Iowa or California
The versatile Big Berkey
®
system is the ideal system for use at home with small or medium sized families, travel, outdoor activities or during unexpected emergencies.
This powerful system filters both treated water and untreated raw water from such sources as remote lakes, streams, stagnant ponds and water supplies in foreign countries, where regulations may be substandard at best. Perfect for outdoor activities and a must in hostile environments where electricity, water pressure or treated water may not be available.
The Big Berkey
®
system removes pathogenic bacteria, cysts and parasites and reduces harmful chemicals such as herbicides, pesticides, and VOCs without removing the beneficial minerals your body needs.
Constructed of highly polished 304 stainless steel, the system comes complete with four 9" ceramic elements. This system has a storage capacity of about 2.25 gallons (8.5 liters) and when in use it stands 19.25" in height with a diameter of 8.5". The upper chamber nests within the lower chamber for transport and stands only 13" in height.
The system will filter about 25 to 30 Gallons (95-115 liters) per day*.
New British Berkefeld PF4 Flouride & Arsenic Reduction Elements
Specifications on the PF4 Flouride & Arsenic Reduction Elements:
PF-4 reduction elements
are designed for use in conjunction with the
Super Sterasyl Ceramic Filter Elements
to adsorb the following unwanted elements found in drinking water.
• Fluoride
• MTBE
• Lead
• Arsenic
• Other residual heavy metal ions
TECHNICAL INFORMATION:
MTBE:
The PF-4
™
is manufactured to exceed ANSI/NSF Standard 53 which requires that MTBE be reduced by at least two thirds from an influent rate
(water going in)
of 15ppb to an effluent rate
(water going out)
of less than 5ppb (
> 95% reduction*).
LEAD:
Tests have shown that when 2000 gallon (7,600 liters) of influent water at a concentration of lead of 150-200 ppb pass through 200 grams of media at a flow rate of 1 gpm (3.8 lpm), the lead level was reduced to less than 1ppb
(>99% reduction).
FLUORIDE:
Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm (11 lpm) per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the media
(>95% reduction).
Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved
(>99.75% reduction).
REPLACEMENT:
Under normal conditions it is recommended that PF-4
™
elements be replaced at six-month intervals
(
Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of total organic carbons, volatile organic compounds or certain inorganic minerals may reduce the capacity and efficiency of these elements.)*.
Note: do not boil this element.
