Do Black Berkey® filters remove limescale?
Limestone is in fact a form of calcium called calcium carbonate. It is rich in calcium but also in dissolved magnesium (mineral salts essential to health). The presence of calcium in water is natural. It comes from the soil that the water has passed through before being pumped and made drinkable. Calcium is a natural element and tap water can provide up to 25% of daily calcium intake. So why remove it?
Well, Berkey® filters do not remove it! The mineral salts are therefore present in the filtered water, for your well-being, unlike the pollutants, which are filtered out.
If, however, deposits accumulate in the tanks due to very hard water, it is sufficient to clean them from time to time with white vinegar and lukewarm water, for example. The filters can be scrubbed on the outside with a soft brush or Scotch-Brite® to clean them and remove any clogged pores.
Black Berkey® Elements
FAQs From Same Category
The composition of the purification elements Black Berkey® used in Berkey® systems is an exclusive, patent-protected formulation based on the assembly of six different types of specific media, including very high quality activated carbon. Assembled in a very compact matrix containing millions of microscopic pores, they allow the creation of a "tortuous path" through which the water will pass but not the pollutants. Indeed, these channels are so fine that all undesirable elements are inevitably captured. Through absorption and adsorption, even submicron viruses are blocked, which other water filters cannot achieve without chemicals.
The activated carbon block is impregnated with an ion exchange resin. Activated carbon adsorbs or chemically binds to organic compounds, such as petroleum-based fuels and solvents, many pesticides and pharmaceuticals. Ion exchange resin removes many dissolved metals from water by exchanging toxic heavy metals (such as lead, mercury and cadmium) for lighter, essentially harmless metals (such as sodium, the main component of table salt). All this allows for a complete and extremely efficient filtration.
Furthermore, the manufacturer Berkey® New Millenium Concept Ltd. confirms that no graphene oxide is used in the composition of the elements.

That's right! Silver is used as an anti-microbial so that each Black Berkey® element can self-sterilize. Analysis was performed by an independent laboratory to ensure that the silver used does not dissolve in the purified water and this is exactly the case. The analysis concludes, "All control samples, including stock samples, positive and negative analytical controls, and the negative control collected prior to plating gave appropriate results and were accepted. Results for the leaching control samples (effluent sample spiked with MS2 and R. terrigena and analyzed at two time points) were quite similar, suggesting that no active antimicrobial agents dissolved in the treated water."

Yes! BPA is not present in any Berkey® system or any part of it. No BPA in Black Berkey® filters and no BPA in the Berkey Light® or Sport Berkey® Filter Bottle either.
Effectively, water that passes through Black Berkey® filters tends to be more basic than it was before. Its pH goes up. And that's actually a good thing... This is because pathogenic bacteria and viruses tend to thrive in acidic environments and have difficulty surviving in alkaline environments. And the higher the pH, the more alkalinity there is.
Nevertheless, it should be kept in mind that the final pH level of the treated water may depend on other factors, such as the pH level of the water before filtration.
