Andy: Water filter follow-up

[Guest guest]

Andy:

Reading more at the Big Berkey water filter site, I may have had it a little

mixed up before.

The ceramic filters, that we're using, use the colloidal silver.

We could use the black filters, which seem to be the ones that more filter out

heavy metals, and don't use the silver:

Would it be imperative that we switch soon? Our ceramic ones are not needing

replacement yet.

Thanks!
