Big Berkey Gravity-Fed Water Filter with 2 Black Berkey Purification Elements

Product Information

They will last up to 11 years before replacement filters are recommended. These set of filters are cleanable and they should be cleaned every 12 months (takes 10 minutes) and giving it the ability to take water from almost any source and produce fresh and pure drinking water. Berkey water filter systems are rated the best and longest lasting water filter systems on the market and they are the top performing portable water filters in the industry. PF-2 filters contain high-grade activated alumina (Al2O3), which currently is the most efficient media available for extracting fluoride from water.

Regarding the PF2 Fluoride filters - Can my in house water filter or other waterfilters on the market remove Fluoride without any additional Fluoride filters? Why do I need to buy additional Fluoride filters? I have seen a test carried out by Berkey which shows it removed progesterone in water. The test did not show anything about oestrogens but when I researched water filters Berkey came up as the only filter that removes disruptors as reverse osmosis and ionisations does not. As oestrogen is far more damaging than progesterone to the body, I would like to know if in fact the Berkey does remove this? They are so powerful that they are classed as a water purification systems and have a much higher standard then normal water filters today.According to the World Health Organization, a non-government agency, Arsenic is one of the major causes of poisoning and death since Arsenic is naturally found in groundwater, which is the source of drinking water in some undeveloped countries in the world. Fill the upper chamber with water and add up to 1 teaspoon of red food coloring for every gallon of water. 3 drops is perfect and enough for Big Berkey test. The first “all-in-one” carbon-based filter element tested reduced fluoride by just 20.8% at 50 gallons (227 litres) , and a mere 14.3% at 100 gallons (454 litres).

According to Wire Cutter, the internals seemed to be comprised of carbon and embedded ion exchange resin.The Big Berkey’s manufacturer, New Millennium Concepts, claims the filter can remove more than a hundred contaminants, far more than other gravity-fed filters we’ve researched. We tested these claims on a limited scale, and our results were not always consistent with lab results that New Millennium commissioned. In particular, results from both our commissioned lab and the lab most recently contracted by New Millennium showed less effective filtration of chloroform than that third, earlier test (which is also listed in New Millennium’s product literature). Berkey systems can efficiently purify ordinary tap water or even raw, untreated water from remote lakes and streams without electricity.

Very infrequently, the filters can have a defect. If for some reason, they are not working after troubleshooting the possible problems. BerkeyHome stands by our high-quality products and excellent customer service.

Why Berkey? What makes Berkey water filters so special?

With respect to the absolute micron rating, there is also confusion because there are two different standards to determine absolute; in the US the standard is 99.9% removal, but the international standard in 99.99% removal or 10 times greater removal. Start with an empty system (upper and lower chamber) and remove any PF-2 Fluoride Reduction filters (if installed). These are only a few but the most common ones endangering our water's reliability. We must be mindful of other contaminants: pharmaceutical drugs and medicines, sewage leaks, and industrial waste. Berkley Water Filter or Berkey Water Filter?
