Do your Black Berkey purification elements filter out PFAS/PFCS?

PFAS/ PFCS also called per- and polyfluoroalkyl substances are a group of man made synthetic chemical contaminants. These chemicals are rapidly being discovered as health risks, and this is a top concern of ours at Berkey Filters. Due to the overwhelming number of chemicals variations (over 5,000) classified as PFAS, we have not been able to test every single PFA. However, it is important to understand the molecular structure of PFAS are very similar to each other. For this reason, our belief at Berkey Filters is that they could be comparably reduced. One of the most publicized PFAS is commonly referred to as Teflon, but it also known as PFOA/ C8, which Berkey removes greater than 99.9%. Check out our article on Berkey Removing PFAS/PFCS.
