Berkey Filters offer more effective gravity filtration than Brita or Pur filters sold at stores, costing much less over time and removing more pathogens, herbicides, pesticides and pharmaceuticals than their store counterparts.
Food dye can be easily tested in your Berkey water filter by placing several drops in its lower chamber. A sight glass spigot can also be added to indicate water levels in this chamber.
Viruses
Under disaster conditions, accessing clean drinking water becomes of critical importance. Berkey water filters provide an efficient means of purifying raw untreated water without stripping its essential minerals; their advanced design means they don’t remove important healthful elements that help the body function optimally.
Black Berkey elements contain microscopic pores too small for viruses to pass through but large enough to trap harmful chemicals and sediments such as trihalomethanes, heavy metals, pesticides, pharmaceuticals, petroleum contaminants, rust and silt. In laboratory tests these elements outshone competitors.
Bacteria
Black Berkey elements mechanically extract bacteria, cysts and parasites (including Giardia duodenalis, Cryptosporidium and Raoultella terrigena). Their performance has been evaluated and shown to remove over one billion E-coli organisms per liter – 10x more than what standard testing limits allow.
Filters contain thousands of microscopic pores to form a barrier similar to surface tension, while using electrostatic charge to draw contaminants against tunnel walls, creating a tortuous path through which they must pass.
Contrary to other water filter systems, the Berkey system preserves essential ionic minerals such as calcium and potassium that are beneficial to our health and add a pleasant alkaline taste to water. Furthermore, its filter system removes heavy metals, industrial chemicals, pharmaceuticals, petroleum contamination from oil spills, Bisphenol-A, Hexavalent Chromium 6 as well as toxic contaminants like chlorine fluoride trihalomethanes herbicides and pesticides from entering our bodies through exposure.
Heavy Metals
Heavy metals such as arsenic, lead, mercury, cadmium and chromium may enter water supplies from mining operations, industrial and consumer waste or acid rain which dissolves soils, entering human bodies where they may cause serious health problems.
Berkey’s Black filter elements have been extensively tested by independent laboratories to demonstrate their ability to reduce a wide range of toxic heavy metals, pathogens and turbidity in water supplies. Furthermore, these tests proved that Berkey’s Black filters aren’t just filters – they serve as true purifiers removing disease-causing microorganisms while simultaneously eliminating heavy metals and other toxins from our drinking supplies.
Black Berkey elements have been designed with care and patent protection in order to minimize removal of beneficial minerals, while drawing water molecules slowly by gravity through their “Tortuous Path” structure – staying in contact with media for much longer than most filter systems that force their filter elements through at high pressure.
Chemicals
Berkey water filters reduce an array of chemicals, such as arsenic, MTBE and fluoride that can have long-term negative health impacts on humans. Furthermore, Black Berkey elements reduce other substances including disinfectant byproducts HAA5, disinfectant byproducts disinfectant byproducts pharmaceuticals pesticides VOCs petroleum products perfluorinated chemicals perfluorinated chemicals perfluorinated chemicals perfluorinated chemicals perfluorinated chemicals perfluorinated chemicals perfluorinated chemicals perfluorinated chemicals perfluorinated chemicals as well as perfluorinated chemicals perfluorinated chemicals per fluorinated chemicals perfluorinated chemicals perfluorinated by perfluorination such as Bisphenol A(BPA). Furthermore, Black Berkey filters eliminate endocrine disruptors like Bisphenol A(BPA).
Filtration works through adsorption and ionic absorption. Micropores in filters create what’s known as a tortuous path for pathogenic bacteria, cysts, parasites, and other impurities to travel through while electrostatically charged contaminants cling to walls of these small tunnels – an effective method of trapping them without forcing them through holes – this also allows filters to remove sub-micron viruses more effectively than simply forcing them through holes.
Sediments
Sediments can harm water quality in several ways, including increasing its turbidity. This makes it more difficult for fish gills to absorb oxygen, and prevent aquatic plants from photosynthesizing photosynthetically. Furthermore, sediments may contain heavy metals and organic contaminants which contaminate the water supply.
Sediment accumulation is both natural and man-made. No matter its source, sediment that accumulates in seas and oceans, lakes, or rivers leaves evidence of past climate conditions in various forms – from mudcracks formed when wet sediment dried out when cracks in rock formed from cracks formed when drying occurred to flute casts – both can help us understand which direction and magnitude of flow deposited this sediment in its entirety.
