I recently excavated a couple of cisterns at Fort Johnson, Charleston
SC (38CH69.com). They didn't have filters, but I did find a number of
patents using Google patents and found a wide variety of styles,
including the pierced stoneware type someone else mentioned.

At Mission San Antonio de Padua in California there is a reservoir with
a
small settling basin attached to it dating to ca. 1800. The basin has
a square
floor tile set upright in the wall, with holes punched throough it.
This
served as a filter to remove large matewrials before entering an
underground
ceramic pipeline. A Spanish construction that is pure Roman in detail.
