In response to recent customers concernsand increased website traffic over a recent article by"The Guardian" over the report on micro plastic in our environment, oceans, rivers and also our tap water as some major cities desalinate ocean water into our drinking water (As does in Melbourne direct into Cardinia Dam), along with the obvious environmental leaching. This report found that the micro plastic particles can also carry pathogens and have a reported size of approx 2.5 micron as scientist world wide test results have revealed. To assure the safety and effectiveness of the Black Berkey® Purification Elements to remove these micro particles is found in the extensive testing of many independent laboratories that exceed the NSF 42 & 53 standard. The Black Berkey® Purification Elements test results prove a Log 4 (99.99%) Log 5 (99.999%) Log 6 (99.9999%) and Log 9 (99.9999999%), the micro pores of theBlack Berkey® Purification Elements are reported as small as0.1 micron but also remove as small as by laboratory results prove
The MS-2 virus is 24-26 nm in size
The Fr Coliphage virus is 25nm in size
24 nm (nanometer = .024 micron)
which far exceeds this problem and safety of your drinking water. The Black Berkey® Purification Elements exceeds the filtration class and are classified as a Purifier.

Re-cleanable and self-sterilizing during the life of the element
Elements come with a 2-year, prorated warranty
Black Berkey® Purification Elementsremove or reduce:
Bad odors and taste, transforms municipal mains water into water that tastes sweet and pure
Chlorine plus Ammonia =Chloraminesto below lab detectable levels
Made from safe, non-leaching Polypropylene #5 that is BPA-free
Berkey PF-2™ Fluoride and Arsenic Reduction Elements are designed to be used in conjunction with the Black Berkey® Purification Elements only
Attach to the bottom of the Black Berkey® Purification Elements and sit in the lower chamber of the Berkey unit
Number of Berkey PF-2™ Elements in the bottom chamber must match the number of Black Berkey® Purification Elements in the top chamber; for example, 4 Black Berkey® Purification Elements would require 4 PF-2 Filters
Set of 2 Berkey PF-2™ Elements need replacement after 1000 gallons (3700 litres) of use
The Berkey PF-2™ Fluoride and Arsenic Reduction Elementsare covered under a six month warranty

PF-2/PF-4 Fluoride Reduction Media Information
(Extract from Proprietary Products Data Information Sheets)
Fluoride Reduction Media Definition: The fluoride removal media is the same mineral that rubies and sapphires (corundum) are made from, in crystalline form. The process ‘selective adsorption’ is a physical/ chemical reaction whereby the fluoride ions are removed by binding to the media’s oxidised surface.
The Berkey® Proprietary Fluoride Reduction Media is a new and improved high yield aluminum oxide (corundum) especially formulated for the removal of Fluoride and arsenic from drinking water. This media has an unusually high surface area of more than 350 sq.m./gram of material which allows more efficient removal of the Fluoride and arsenic ions. This high surface area is enhanced by controlled development of the pore size distribution from 30 Angstroms to 100 Angstroms, providing greater accessibility to the surface active sites through bulk diffusion.
Uniform particle size low silica content and high purity, is characteristic of the new and improved Proprietary Fluoride Reduction Media which insures effective operation in the reduction of Fluoride. The extremely low silica content significantly reduces the tendency of the silica to form silicone tetra fluoride which reacts with both the media and the pipes leading to clogging and corrosion problems.
The Proprietary Fluoride Reduction Media is an EPA approved method for removing Fluoride from drinking water. This product can be used in various filtration products and can also be packed in large columns for high volume applications including drinking water treatment plants and waste treatment plants. The Proprietary Fluoride Reduction Media can be used in various applications where defluorination is necessary.
For maximum removal efficiency, maintain the water being treated between a PH level of 5-7. The media can be regenerated for enhanced performance lifetime with many applications. This makes the Proprietary Fluoride Reduction Media the most effective and economical defluorination product on the market.

TYPICAL CHEMICAL PROPERTIES OF PROPRIETARY FLUORIDE REDUCTION MEDIA:
The Proprietary Fluoride Reduction Media has been specially prepared to optimize the media for more efficient removal of the Fluoride ion. Testing of the material is important for each application as influent water PH, quality and purify of the water and various metal ion concentrations are all variables which influence the effectiveness of the media. Note that the material is most efficient between a PH of 5 and 7.
Testing for fluoride removal was based on 20-30 ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm per cubic foot (25kg) of media. Results of < 1 ppm of the fluoride ion in the effluent were typical for the media. Under optimum conditions, effluent concentrations of less than 50 ppb of Fluoride ion were found to be readily achieved. Results may vary significantly with each particular application.
1. Calcium & Sodium Fluoride. The Proprietary Fluoride Reduction Media will remove any types of inorganic fluoride salts. All fluoride salts are soluble in water. So it does not matter what fluoride salts that are in the water, fluoride is present as an anion where the media will absorb fluoride ions in water.
2. Hydro-Fluorosilicic Acid (HFS). We do not have any test data to show how efficient the Proprietary Fluoride Reduction Media will remove hydro-fluosilicic acid. But by adsorption of fluoride anion using alumina, we believe the media will remove hydro-fluosilicic acid better than fluoride. The reason is both compounds are ions with negative charges. The molecular size of hydrofluosilicic acid is much larger than the fluoride ion and hydrofluosilicic acid has two negative charges where as fluoride has only one negative charge. So this negative charge makes hydrofluosislicic acid much easier to adsorb to the media compared to regular fluoride ions.
3. NMCL obtains its Proprietary Fluoride Reduction Media from a third party that manufactures specialized media that targets difficult to remove contaminates, such as Fluoride and Arsenic.
