Yes that's a ceramic. As with everything, they have limitations,
advantages and disadvantages. That site needs to update (copyright 1997)
their content, there are a number of things they are not current with
(on just the one page I read). Such as (certain) UV does deactivate
viruses and cysts. There are disposable cartridges containing either
cation or anion resins and a number of other medias. Ceramics don't
remove viruses and are hard to impossible to disinfect. Silver is not
good for humans if there is too much of it in the treated water etc..

For bacteria control, UV with a combination of pre/post filtering is the
best overall way of treatment. Usually POE (point of entry) treatments
are much better than POU (point of use) types but UV comes in both
types; with and without pre and/or post filtration.
