British Berkefeld Information
Standard Model and Big Model
British Berkefeld® water filters are also compact, portable, and simple to operate. Requiring no external plumbing, each filter takes only minutes to assemble and can provide up to 24 gallons or more of safe drinking water each day. The high-tech silver-impregnated ceramic elements feature a nominal filtration efficiency of : 0.2 microns, greater than 98%, at 0.5 microns, greater than 99.9%, and at 0.9 microns, greater than 99.99% which effectively blocks waterborne pathogens and clarifies the water.
These filters are in common everyday use in households across the country, and are particularly effective on private well systems. The replacement filter elements have an activated carbon core and are designed to remove undesirable tastes, odors, and many organic chemicals.
The ease of operation combined with a proven effectiveness at eliminating water-borne diseases such as cholera and typhoid has led to the filter being the preferred unit for field operations by many of the world's major aid and emergency relief organizations.

The special ceramic elements are manufactured specifically for use in this gravity filter. British Berkefeld ceramic elements consist of a fine microporous structure, which forms a complete barrier to all particles larger than 0.5 microns in size (1 Micron = 1/1,000th of a millimeter). All particles above this size become trapped on the surface and within the ceramic material. Fine particles of silver are evenly dispersed within the structure of the filter element, which prevent the growth of bacteria (mitosis) within the ceramic wall. The British Berkefeld elements also contain an additional activated carbon filling, which removes chemical and organic compounds from the water and improves its taste and odor.
Our high-quality British Berkefeld® gravity water filters offer these advantages and convenience:

Individual Model is extra.
Newest model is the PF-4 set of 4 Filters. Fits in the Big Berkefeld and Regular British Berkefeld 4X4 Unit. Item #NP008. Filters Fluoride, Arsenic, Lead and MTBE. Replace filters every 6-12 months depending upon usage .
British Berkefeld MTBE Water Filters
New P-4 MTBE Filters also remove, Chlorine, Floride, Lead and Heavy Metals. Set of 4 screws into the Regular British Berkefeld 4X4 Unit. Super Sterasyl Filters work in the upper chamber, MTBE P-4 Filters in the lower chamber. Unfortunately MTBE is now turning up in wells, underground aquifers, lakes and reservoirs.
60-Minutes' Steve Kroft revealed that MTBE is now the second most common water contaminant in the country. One internal study conducted by Chevron discovered that MTBE had contaminated the ground water at 80 percent of the sites the company tested. Remarkably, there are no requirements for local governments, municipalities and water providers to test for the presence of MTBE contamination.In March of 1996, the city of Santa Monica California discovered that MTBE had contaminated 7 of its 11 wells. The water in these wells took on a strong chemical odor and simply became undrinkable. The wells were closed and today Santa Monica spends about $3 million dollars per year to obtain water from the Colorado River. Since then, the state of California has identified 10,000 sites where MTBE is present in groundwater. MTBE has now been detected in the ground water of 49 states including major cities such as Atlanta, Albuquerque, Dallas, Denver, Hartford, Las Vegas, Long Island and others. In South Lake Tahoe California, MTBE was discovered in the lake, the groundwater and in a dozen wells. One third of the city's water was shut down. They are now suing 12 local gas stations, 12 major oil companies and several manufacturers of MTBE according to Victor Sher, an attorney representing the city. 60-Minutes' Kroft conveyed that in New Jersey, it has been found in 65 public drinking water supplies and in Long Island New York, MTBE has leaked from more than 400 gasoline storage tanks and is now being detected in more than 100 public water supplies. Glennville, California had some of the highest levels of MTBE ever recorded in drinking water. One well tested at 20,000 parts per billion, 1,000 times greater than the maximum level the EPA is now recommending. Today, Glennville has become a virtual ghost town. Recently, 500,000 gallons of MTBE laden gasoline was spilled in the Dallas area contaminating 30% of its water supply.
Dr. Bernard Goldstein, a toxicologist and the director of the Environmental and Occupational Health Sciences Institute in New Jersey says, "anyone who looked at the chemical properties of MTBE would have known it was going to pollute water". He explained that the oxygen in MTBE makes it more soluble in water than almost anything else found in gasoline. It moves rapidly in groundwater once it gets spilled. In a report issued by Dr. Peter Garrett of the Maine Department of Environmental Protection and two of his colleagues stated that "MTBE moved further and faster in groundwater and was more difficult to clean up than any other contaminate in gasoline". The problem is that MTBE doesn't break down. Craig Perkins, director of public works for Santa Monica stated "What we found was that it was behaving much differently than contaminants that-that (sic) we had tracked in the past. It was moving through the-the (sic) groundwater into the wells much more quickly. On one of our wells, the-it (sic) essentially doubled within one-week period".
A 1987 EPA memo states "Known cases of drinking water contamination have
been reported in four states, affecting 20,000 people. It's possible that this
problem could rapidly mushroom due to leaking underground storage tanks. The
problem of groundwater contamination will increase as the proportion of MTBE in
gasoline increases." The Clean Air Act of 1990, which mandated the use of
oxygenated fuel additives, was passed three years later. Bob Perciasepe, an
assistant administrator of the EPA told 60-Minutes "any optimism anybody
had that we could manage the potential problem has not come to fruition, and
before this becomes a national crisis, before this gets worse, we need to change
the way we make clean-burning gasoline". The Environmental Protection
Agency recently said it would move to ban the substance after recent studies
showed it contaminates water supplies across the country. MTBE can cause water
to take on a chemical odor similar to that of turpentine or paint thinner. A
study conducted in Italy on lab animals showed that ingesting high doses of MTBE
caused leukemia, lymphoma and testicular cancer. MTBE has not been adequately
tested for toxicity in humans and scientific data of its long-term human health
effects is sadly lacking.
Contamination of groundwater with MTBE is a rapidly growing problem in 49 U.S.
states. In drinking water, even trace amounts of MTBE can cause taste and odor
problems, which may lead to nausea and dizziness. The potential long-term health
effects of MTBE are not understood at this time, however, initial studies
indicate MTBE may cause kidney and liver problems. MTBE removal from water is a
challenge because it is very soluble in water and must compete with other
organics for binding sites on the filter medium. These other contaminants (BTEX
- butane toluene ethylene xylene and TOC - total organic carbons) are adsorbed
more readily, and MTBE often slips by standard carbon filters, ending up in the
filtered water. The PFE-1 filter has been specifically designed to remove MTBE
from drinking water when used in conjunction with a British Berkefeld gravity
filter system. The media within the Super Sterasyl filters, in the upper
chamber, capture the more strongly adsorbed BTEX and TOC's. This permits the
downstream PFE-1, secured as a post filter, to more efficiently remove MTBE.
