Subject: Big Berkey Water Filter Fri Sep 03, 2010 11:12 pm
I have a friend who owns one of these things and swears by them! They come in different sizes and shapes but is perfect for pretty much anywhere. You can take dirty pond sludge and put in this thing and get out perfectly clean water. I'm not sure about whether they still need to be chemically treated but it's a piece of cake. However one of the big things with the Berkey is that it also has a fluoride filter which fluoride is VERY hard to filter out!
Again, these can be kind of expensive but from what I've heard, they are worth the money.
