I’ve watched a few videos on the subject and I’ve come to this conclusion myself, there might actually be a reason for them trying to ban them but I’m not sure if that will end up being what they ban. There’s been reports of aluminum in some filters leaking into the water so I hope they just go for those specific ones and not all Berkey filters. If they have something that caused problems, ban that, don’t go for the whole line unless there’s a larger contamination problem in all the tanks or filters
