The proprietary filter formulation used in Black Berkey® Purification Elements makes up for the incredibly small pore size by utilizing an exponentially greater number of micro pores in each purification element than that found in other filter elements. This is the reason Black Berkey® Purification Elements produce approximately 8 times more water per hour than other elements. While some of […]
The micro fine pores are so small that they prevent micro fine particulate such as bacteria, viruses and even food coloring particulate from passing through the tortuous path that water is able to pass through. These contaminates are trapped in the micro fine pores while the much smaller H2O molecules are not. This method separates […]
Is the MS2 – Fr Coliphage still known to be a good indicator of virus filtration? Do you have tests on any other viruses?
MS2 and Fr Coliphage are two separate viruses with two different removal characteristics. That is why they are used as surrogates for other types of viruses. These viruses were selected, by both the EPA and the Military, because of their small size relative to other virus strains and the difficulty in removing both strains. They […]
